Review: Deadly Docents, Dirty Varnish and a Big Educational Push at the Frick

The hardest thing to do in today’s internationalised world of museum administration is to stand still. A trip to New York always compels a visit to the delightful time-frozen art palace that is the Frick Collection but it would seem that, even there, maintaining the status quo there has proved unendurable. Madcap schemes to build new galleries for new exhibitions under the Frick’s garden have been drawn up. It is possible that the new director, Ian Wardropper (former chairman of the department of European sculpture and decorative arts at the Metropolitan Museum of Art), has dampened ardour for the kind of curatorial and physical “bolt-ons” that have skewed similarly bequeathed jewels like the Wallace Collection in London and the Phillips Collection in Washington (where today the historic works and their period architectural setting have been swamped and diminished by curatorial and architectural expansionism; where today “Special exhibitions are a signature element …offering new perspectives on the work of contemporary and modern artists.”) The Frick’s director does however seem minded to expand the audio tours and “other educational programs” and a book prominently displayed in the Frick’s shop (see right) serves as explicit manifesto for Education’s bid to interpose itself noisily at the very centre of museums between art and its visitors. As the painter Gareth Hawker describes below, something vital and of the essence is threatened by the prospect. And, as the painter James Keul discovered on a recent visit, something similar is already up and running at the Getty:

The docent in the Rembrandt room of the East Pavilion upper level, which covers art from 1600-1800, was speaking to a tour group of about 20 people, mostly middle-aged, and asking what observations people had made on the small painting of the Abduction of Europa. One member of the group asked why all of the paintings appear so dark. The docent answered that varnish and oils applied over the years had darkened, leaving many works darker than they were intended to be. Presumably, this was meant to plant a seed in peoples’ minds that all dark paintings are the result of a darkened varnish rather than an intended effect that was used, in this case by a Baroque artist, to provide contrast and thus bathe a picture in a divine light…”

Gareth Hawker writes:

Visitors who plan a quiet hour or so contemplating works of Art in an American museum risk being accosted by guides called “Docents” who intend to deepen their museum experience. Docents, according to Rika Burnham and Elliott Kai-Kee, the authors of “Teaching in the Art Museum: Interpretation as Experience” (2011, Getty Publications – see Figs. 1 – 4), seek to enable the visitor to “make meanings”. The book’s purpose “is to explain making meanings – to open the world by means of art”. Although many readers might be baffled by such sentences as: “metacognition is a byproduct of practice and it facilitates profound experience”, Burnham and Kai-Kee’s respective positions as Head of Education at the Frick Collection, New York, and Education Specialist at the J. Paul Getty Museum in Los Angeles, requires that their campaign to help docents influence a whole culture by shaping the public’s attitude to works of Art be examined.

Docents are amateur enthusiasts, who have been trained to a high level – though not to degree standard – in both teaching and art history. They come from all sorts of backgrounds, and are of all ages. They probably think of themselves as more or less ordinary people who enjoy appreciating art and wish to help others to do so.

The position of the Docent was created in 1907 in response to a perceived need. Visitors to art galleries wished for a guidance in appreciating works of art which was deeper than that being provided by art-historical lectures. Docents were trained and appointed to meet this need by providing an education in aesthetic pleasure. Nearly a century later, there is no longer agreement about what might be meant by “an education in aesthetic pleasure”. So this book appears at an opportune moment, just when museum educators are seeking to clarify their roles.

In order to help redefine their objectives, Burnham and Kai-Kee refer to the work of the educationalist John Dewey who wrote in his classic 1934, Art as Experience, that “The task is to restore confidence between the refined and intensified forms of experience that are works of art and the everyday events, doings, and sufferings that are universally recognized to constitute experience.” Dewey had identified an ideal response to a work of art. The visitor would begin by gaining an “experience” (that is, a sense of unity). A teacher might help the visitor in this, by stimulating and guiding his thoughts, but without ever imposing any view or judgement. In this way, “guided interpretation” might help the visitor to “make meaning” – to recognise relationships in many aspects of life and art. At its highest this process can generate a sense of over-arching interconnectedness which Dewey called a “culmination”.

In one exercise, students working in a group are encouraged to offer up any ideas and reflections which come to mind in reaction to a painting. These “thought showers” sound as if they could be open and productive, but, if a student asks an awkward question, the process seems to go into shut-down, as the following account (p. 71) may illustrate:

The picture (the Frick Saint Francis by Giovanni Bellini) is beginning to cast its habitual spell. Suddenly, without warning, in a slightly confrontational tone, one man in the group asks, ‘What’s the difference between a work of art and a mere illustration? This might be just an illustration.’ [See Fig. 2] The question raises larger philosophical issues that are more difficult than he probably realizes and than I can accommodate in the context of a gallery program. I urge him to be patient. Perhaps the experience of the painting may begin to resolve the question, at least for him.”

The docent hopes that the student’s experience of the painting might begin to resolve his question – ignoring that fact that it was his experience which had prompted the question in the first place. Perhaps only certain types of experience are acceptable. (Dewey made a distinction between “experience” and “an experience”). The docent also suggests that the student’s question might be resolved, “for him”, as if his question were personal; as if he were troubled by a mental hang-up; and as if she were his counsellor. But his question was not personal. It was a general question about how works of art may be classified. An answer which was good only “for him” would not have addressed the issue – if indeed such an answer could have any meaning at all.

So, to summarise, the teacher has judged that her student has had the wrong kind of experience, but will not explain why; she judges that he is probably ignorant of issues which are connected with his question but she will not tell him what they are. This begins to look less like an application of Dewey’s theories and more like a power-struggle in which the docent issues a put-down and asserts her superiority.

As so often throughout the book, while the theories seem perfectly innocuous, even illuminating, it is the way in which they are put into practice which gives cause for concern. The authors seem to share a general squeamishness about talking about artistic quality. This is a mindset which is just as prevalent in Museum education in the UK as in the USA. While the authors appear to accept Dewey’s observation that works of aesthetic merit may be found at all levels of human endeavour, not solely in High Art, they apparently interpret this to mean that one must not point out the difference between good and bad.

The authors do mention the importance of looking and seeing, but by these terms they seem to mean finding and telling stories, rather than observing shapes and colours. Works are treated as objects to be read, like books, with stories to be discovered and assimilated. Looking at a painting for its artistic qualities is considered only as a small part of a student’s involvement, not of central importance. (Whistler’s Ten O’ Clock lecture, with its concentration on qualities such as colour, tone and shape, would form a stark contrast to the narrative approach outlined here.)

For the authors, talking is an essential part of the process of experiencing a work of visual art. The authors would like to see the docent become increasingly prominent in museums. They wish to see teaching develop in such a way that, “galleries may be defined as places where dialogues take place around works of art” (p. 151). This means that galleries would no longer be defined as places where one goes to look at paintings. They would no longer be quiet. The authors envisage galleries “filled with the hum of conversation […as] educators move from the periphery to the center.” But this move may have harmful consequences. If visitors learn to think of the appreciation of works of art as a series of “experiences”, with little regard to artistic quality, their eyes will be closed to many fundamental aspects of the art of painting. Such visitors are unlikely to observe that some pictures are better than others. They will not notice when quality has been reduced over time: when paintings have been degraded by insensitive restoration “treatments”. Their non-judgemental, non-critical stance will make them easy prey for apologists who promote restorations with appeals to crude sensation such as, “now we can see what was underneath that dark paint!” or, “now look at how bright that blue has become!”

Works of art will be relegated to the status of tools which enable the visitor “to open the world by means of art.” Defining the function of art in this way is simplistic. Art can have many meanings or none at all, yet we can still recognise that it is “right” – if our minds are quiet. Yet the museum of the future which the authors envisage is hectic and noisy.

Responsible for the continuing translations of meaning that occur in the new museum, the educators who teach are the most accomplished members of the education department, best qualified to shape and animate museum programs. They lead the department, define its philosophy and mission, and overturn the historical definition of teaching as a peripheral, volunteer, or entry-level activity.”

If, by “translations of meaning” the authors mean anything like the “guided interpretation” we have seen in the verbatim accounts of their teaching sessions, we know that it will involve subtly pressurising the visitor to conform to their view of art, “shaping and animating” his “experience”.

A quiet hour contemplating beautiful paintings looks likely to become ever more elusive if the authors get their way.

Art and its Appropriators ~ A Note on the Barnes Foundation, Merion, Pennsylvania (Michael Daley)
In “Teaching in the Art Museum” (p. 3), Rika Burnham describes the concluding essay chapter on the Barnes Foundation as “a special case study in museum education”.
The Barnes, as a foundation whose primary purpose was educational, rather than being a museum in which teaching happens to take place, appealed greatly to the author – even as its method was rejected. Invited in 2003 to teach as a guest lecturer (unusually, for one untrained in the Barnes method), Burnham came to appreciate how Albert Barnes had collected and assembled a collection to be continually rearranged “by the teachers” so that they might make visible a “continually evolving universe of art and ideas”. If outdated as a pedagogical system, the central role of the educator in the Barnes foundation’s mission was seen to offer “rich possibilities as a model for the future of our profession”.
Above, fig. 3: Albert C. Barnes with Renoir’s “Bathers in the Forest” (left). Photograph of 1932 from the Barnes Foundation Archives.
Barnes, like Henry Clay Frick, was a ruthless accumulator of wealth but where Frick amassed prime art specimens like some super-philatelist, Barnes was gripped both by specific artistic passions and generous democratising impulses. Above all, he was in thrall to Renoir’s late and summary, non-impressionist, nude paintings. An intimate of and close collaborator with John Dewey, Barnes bequeathed his stupendous collection (a thousand pictures with over one hundred and eighty Renoirs) as the tool of an educational method. Executed with his money, his works of art, and according to his and Dewey’s ideas, this unique experiment affronted many in the artworld. As the cash value and the esteem of the collection rocketed, covetous eyes grew impatient with the foundation’s high-minded purpose and began seeking ways to prise the art away from a distinctive teaching method that encouraged/demanded that the student make the great mental effort to acquire the specific habits of perception of artists so as to see as the artist sees.
Above, Fig. 4: Two of the original (now shamefully denuded) Barnes Foundation galleries, as published in “Teaching in the Art Museum”.
When Rika Burnham, the Frick’s present Head of Education and a former Getty Museum Scholar, undertook her teaching at the Barnes, she did so with evident trepidation. Her account (p. 134) opens like a Hammer horror film set in Translyvania:
Darkness is falling in Merion, Pennsylvania, as I leave the station and walk slowly up the hill and turn onto North Latch’s Lane. The year is 2003 but it could just as easily be 1950. Unchanged, the Barnes Foundation stands silent, proud, only slightly faded by time and the endless controversies that have swirled around it since Albert C. Barnes died in 1951. The night watchman at the front gate pokes his head out and says they are expecting me. I walk up to the massive wooden doors and lift the large knocker, pausing for a moment to imagine the treasures inside. My knock sounds heavy and hollow. Slowly the door opens…my heart is racing. Twenty years of teaching at the Metropolitan have not prepared me for teaching in an installation like this.”
Burnham’s dilemma was this:
Is it possible to teach with these works of art, I wonder, as my eyes adjust slowly to the complex arrangements, the soft but dim lighting? How could I teach in these cacophanous arrangement of art objects? How could I help my students see and make sense of the art in what appear to be overflowing, even hyperactive spaces?”
It sometimes seems that the default response of every museum employee and volunteer, when confronted by an old painting, is to complain knowingly about its “condition”. Perhaps in a field heavy with “conservators” it would be held professionally tactless or even provocative to entertain the possibility that non-treatment might ever be preferable to “conservation”? Burnham was first required to talk about two early Netherlandish devotional pictures given to the school of Gerard David, a “Virgin and Child” and the “Crucifixion with the Virgin, St John, and the Magdalene”. She immediately took against the two works and their setting:
However, questionable attribution is only one of my concerns. Both pictures are darkened by varnish and surrounded by many objects and other pictures. My heart sinks. It is hard to imagine that we will be able to see much, let alone sustain study and dialogue.”
One senses on Burnham’s own account that the Barnes students may have come to the rescue of a disoriented teacher:
This is a second year class; the students have spent the previous year learning the Barnes method of seeing. One is a psychologist, another a lawyer, and still others are artists…We sit and begin in silence. We search for words, describing what we see, at first hesitatingly, then with more confidence. Through our shared dialogue we slowly begin to unfold the small ‘Virgin and Child’. The students are patient and disciplined in their looking, persistent. The small work of art becomes large and radiant to our eyes, its spiritual mystery paramount, while questions of attribution and history, for the moment, recede.”
Such revelatory surprises were to come thick and fast. Not only was the varnish-darkened picture possessed of radiance, but Burnham was surprised by its ability to command any attention at all “given that it is surrounded by many other works of art, some large and imposing.” The teacher, already a veteran Metropolitan Museum Educator, came belatedly to the realization that “pictures can be part of their ensembles, yet still assert themselves…”
Week after week and, seemingly, against all odds, pictures were to come alive for Burnham. El Greco was reached.
Above, Fig. 5: El Greco, “Vision of Saint Hyacinth”. For its display context at the Barnes, see Fig. 4 (top).
For Burnham, the attributional quibble came first: “Perhaps painted by El Greco or by his son, Jorge Manuel, it is one of three versions of the subject.” Such doubts notwithstanding, “We look intently, searching for meaning and understanding, and again, the picture shines through its darkened coat of varnish.” A landscape by Claude Lorrain is at first seemingly inaccessible hanging over a glass case, but it too “triumphs over dim evening light and yellowed, aging varnish”.
Although her heart initially sank on entering the Barnes collection, Burnham now hopes that despite its enforced move to downtown Philadelphia, the collection may yet “inform our museum education visions…as we search for a pedagogy advancing our own questions, promoting freedom, and serving us as we seek ever-deeper understanding of the artworks we love”. One senses likely obstacles to this ambitious prospectus: there is an institutionally insurrectionary, anti-curatorial, anti-scholarly bias that, paradoxically, requires building an alliance in which curators must relinquish authority: “If education truly is central to the mission of art museums, as most have claimed since their founding, I believe that educators must collaborate with curators and conservators so that that objects can be free to engage in dialogues with one another that are not limited only by curatorial imperatives.” It is hard to see how – outside of the Barnes as it once was – it could be other than a daydream to call for a world in which throughout “museums big and small, works of art can be moved into surprising juxtapositions at the request of the teachers, to create new dialogues and open new horizons.”
Moreover, the Barnes’ enforced migration has had disastrous consequences for what might once have served as an educational beacon. Wrested from its bequeathed purpose-built beautifully landscaped and architecturally handsome home (with distinguished carved sculptural decorations), the Barnes collection has been deposited within a mean-spirited conservationally sanitised replication of its old interiors. Moreover, these are set within an ugly, affronting, clichéd modernist mausoleum that in repudiating history celebrates nothing more than its own materials and its tyrannical soul-destroying rectilinear aesthetic obsessions – an aesthetic which nods derivatively and dutifully to the “signature” modernist roof-top glass box that has been defiantly bolted on to the top of Tate Modern’s own “modernised” historic building. Compounding the offences against art and generosity of spirit that this hi-jacked legacy constitutes, it transpires that the new building already serves (in flagrant breach of the terms of Barnes’ stipulations) as yet one more commercial “events venue” with a “nice museum attached”.
That betrayal has not gone unchallenged. In yesterday’s Philadelphia Inquirer, Nicholas Tinari, a patent attorney who studied at the Barnes from 1989-91 and later co-founded Barnes Watch in attempt to stop the trustees of the Barnes Foundation from altering the terms of its indenture of trust, speaks of his anger and sadness at the opening of the gallery in Philadelphia: “anger at the gross betrayal of Albert Barnes’ remarkable gift and sadness “for something truly unique [that] is gone, not only an art collection in the perfect setting, but an original idea.”
Tinari’s heart-felt sadness is realistic – a dream has died. The Barnes experiment is not universally replicable and its high aesthetic demands could certainly not be met in the envisaged relativist talking shops when “In the art museum of the future, we walk into a gallery in which the hum of conversation fills the space”. In François Truffaut’s film version of Ray Bradbury’s “Fahrenheit 451″ the “book people” are seen wandering around talking to themselves in order to keep alive the chosen book that they have committed to memory in a society where books are outlawed and destroyed as anti-social. In the transformed museum espoused by Burnham and Kai-Kee, the silent contemplation of a painting will give way to group inductions by educators who make themselves “responsible for these dialogues”; who ask to have a central place in the future museum. In practice, such a transformation threatens the greatest gift that a work of art offers: its implicit invitation to individual viewers to think their own thoughts, to have their own responses, to commune in tranquility directly with the artist. That is the great luxury and privilege that the museum makes possible to all comers regardless of wealth and ownership. Michelangelo once said that he was never less alone than when alone with his thoughts. Can art’s educators really not appreciate that guaranteeing to all the circumstances that permit vivid, living personal, one-to-one engagement with art – to the value of which the authors of this book themselves eloquently testify – should be the primary objective of all museum administrators? It is the art itself that is educational. We do not get waylaid in theatres and concert halls by would-be explainers, nor should we in galleries. Art appreciation classes belong in the class-room.

Rocking the Louvre: the Bergeon Langle Disclosures on a Leonardo da Vinci restoration

ArtWatch has been haunted for two decades by a nearly-but-not-made restoration disclosure. In the 1993 Beck/Daley account of the Nippon TV sponsored Sistine Chapel restoration (Art Restoration: The Culture, the Business and the Scandal), we reported that in the late 1980s Leonetto Tintori, the restorer of Masaccio’s “Trinity” in the Santa Maria Novella, Florence, and a member of the international committee that investigated the controversial cleaning, had “urged the Sistine team privately to preserve what he termed ‘Michelangelo’s auxiliary techniques’ which in his view included oil painting as well as glue-based secco” (p. 111). What we had not been able to say was that Tintori (who died in 2000, aged 92) had prepared a dissenting minority report expressly opposing the radical and experimental cleaning method.

Shortly before the press conference called to announce the committee’s findings, Tintori was persuaded by a (now-deceased) member of the Vatican not to go public with his views. He was assured that his judgement had been accepted and that what remained on the Sistine Chapel ceiling of Michelangelo’s finishing auxiliary secco painting would be protected during the cleaning. With a catastrophically embarrassing professional schism averted, the restoration continued and the rest of what Tintori judged to be Michelangelo’s own auxiliary and finishing stages of painting was eliminated. Without knowledge of Tintori’s highly expert dissenting professional testimony, the public was assured that despite intense and widespread opposition the cleaning had received unanimous expert endorsement. Critics of the restoration were left prey to disparagement and even vilification.

On January 4th, we noted that in the widely reported schism that emerged at the Louvre with the resignations of Ségolène Bergeon Langle, the former director of conservation for the Louvre and France’s national museums, and, and Jean-Pierre Cuzin, the former director of paintings at the Louvre, from the Louvre’s international advisory committee on the restoration of Leonardo’s “Virgin and Child with St. Anne”, it had been recognised that the resulting crisis of confidence was of a magnitude not seen since the Sistine Chapel controversy. Restoration advisory committees are not imposed on museums and customarily they serve as political/professional fig leaves. In the wake of the Louvre committee resignations, embarrassed and perhaps panicky members of the museum’s staff offered self-contradictory and unfounded assurances (see below). In January, the Louvre’s head of painting, Vincent Pomarède reportedly claimed that “The recent cleaning was absolutely necessary for both conservation and aesthetical reasons.” This assurance proved unfounded on both grounds. Pomarède added that no member of the committee “has ever said that the cleaning was not prudent and had gone too far technically.” One has now done so – publicly – and left museum restorations under an unprecedented spotlight.

During an earlier cleaning controversy at the Louvre, Edgar Degas threatened to produce an anti-restoration pamphlet that would be what he termed a “bomb” – but he never did so, so far as we know. Now, as Dalya Alberge reports in the Guardian, the French Le Journal des Arts yesterday published an interview with Ségolène Bergeon Langle of truly momentous if not incendiary consequence (see below). We learn that her resignation came after no fewer than twelve letters requesting information on the restoration’s course went unanswered; that it was made in specific and pointed protest against the use of retouching pigments whose safety had not been proven; and, that the Louvre’s public claims of some pressing conservation need to remove the varnish were false, having been made despite it being known within the museum that any potential threat to the paint came not from the varnish but from a single faulty board in the picture’s panel which was reacting to the museum’s insufficiently stable environmental conditions. Perhaps most disturbingly serious for art lovers are Bergeon Langle’s disclosures that along with old (but nonetheless still protective) varnishes, original material of Leonardo’s was removed – against her advice – from the painting; and, aesthetically, that it is confirmed that the modelling of the Virgin’s face was weakened (see Figs. 1 and 2; and, for weakening to the modelling of St. Anne’s face, Figs. 12 and 13).

That the Louvre authorities would not inform even so distinguished a member of its own advisory committee might suggest either that the restorers had not known in advance what they would be doing to the painting; or, they feared that disclosure of their intentions would provoke opposition within the advisory committee. Either way, this was clearly an unacceptable (if not improper) way for a museum to execute irreversible alterations to one of Leonardo’s most advanced sophisticated, complex and problematic works. To Bergeon Langle’s now public “insider” criticisms, additional detailed material to highlight further Louvre procedural shortcomings and misrepresentations to the press and to the public will shortly be presented by Michel Favre-Felix, the president of the Association Internationale pour le Respect de l’Intégrité du Patrimoine Artistique (ARIPA). Favre-Felix is also to call formally for the establishment of a national scientific ethics committee that would be independent of museums and their restoration teams and be charged with re-examining the conservation file on the challenged St. Anne restoration.

A second member of Louvre’s advisory committee, Jacques Franck, the world authority on Leonardo’s painting technique, has said to the Guardian that a restoration likely to generate such disapproval from leading figures should never have been undertaken in the first place and, given that Ségolène Bergeon Langle is unquestionably France’s highest authority on restoration matters, her alarmed protest is therefore one that should mean a lot to both Leonardo scholars and art lovers the world over.

Unfortunately, the restoration-induced changes on the St Anne are not unprecedented. It is Art’s general tragedy that while scholars have quietly enlarged the oeuvre of Leonardo over the last century and a half, restorers have repeatedly swabbed and scritched away at the surviving fabric of those precious works – sometimes to an astounding degree, as with the “Last Supper” in Milan. With the National Gallery’s substitute version of the “Virgin of the Rocks” we have seen how the distinctive Leonardesque expression on the angel’s mouth was altered (without any acknowledgement) despite the fact that a distinguished scholar and former director of the Gallery, Kenneth Clark, had seen the angel’s face as being “the one part of our Virgin of the Rocks where the evidence of Leonardo’s hand seems undeniable, not only in the full, simple modelling, but in the drawing of the hair”. It is a matter of note that four of the most enthusiastically supportive members of the Louvre advisory committee were drawn from the curators and restorers who were directly responsible for the London and Milan Leonardo restorations.

Of Leonardo’s accepted earlier paintings, in 1939 Kenneth Clark lavished especial praise on the treatment of modelling found on two portrait heads – and in his enthusiasm, he awarded the palm of best preservation to both of them. The “Ginevra Benci”, then in the Liechtenstein Collection but now in the National Gallery of Art, Washington, was judged “the best preserved of all Leonardo’s early pictures”; one that “shows most clearly his intentions at this period”; and, one where “within the light oval of the face there is very little shadow, and the modelling is suggested by delicate gradations of tone, especially in the reflected lights.” Clark thrilled to the great refinement of execution: “We see a similar treatment of form in Desiderio’s low reliefs, controlled by the same sensibility to minute variations of surface. There are passages, such as the modelling of the eyelids, which Leonardo never surpassed in delicacy, and here for once he seems to have had none of that distaste for the medium which we can deduce from his later paintings, no less than from contemporary descriptions of his practice.” Ever aesthetically alert and deft, Clark saw all of these ultra-refined technical devices as being entirely “subordinate to the feeling of individual character with which Leonardo had been able to charge his portrait, so that this pale young woman has become one of the most memorable personalities of the Renaissance.” (We are grateful to Carroll Janis for drawing attention to this passage.)

Clark’s alertness to the physical/aesthetic characteristics of Leonardo’s hand was to the fore in his reflections on the “Portrait of a Musician” at the Ambrosiana in Milan. In the “subtle luminous modelling” of its head and its “delicate observation of light as it passes across the convex forms”, this work could only be “by Leonardo’s own hand alone and unaided” and it was “very similar to that of the angel in the Virgin of the Rocks”. As it stood before 1939, this too was “perhaps the best preserved of Leonardo’s paintings”, and in it we were then able to “learn something of his actual use of pigment, elsewhere obscured by dirty varnish, and we see that it was less smooth and ‘licked’ than that of his followers.”

Ironically, Clark, with his pathological aversion to “dirty” varnish (which is to say, old varnish on an old painting on an old support), was more responsible than anyone for the subsequent museum restoration/stripping mania. Looking around today’s museums, it is hard not to conclude that Clark might have been more careful in his wishes. Bergeon Langle’s warning against the modern addiction to penetrative imaging systems is particularly apt and timely: the hyper-active restoration changes (see right) made to the modelling and to the expression of those precious living Renaissance faces have cumulatively thinned and abraded pictures surfaces and material components and thereby remorselessly pushed great paintings into sad resemblances of their own infra-red under-states (see particularly, Figs. 4-11 and 19 & 20). Technical curiosity kills more than cats. In the case of Leonardo it has contrived to pull that artist back from his own increasingly lush highly-wrought subtly atmospheric shading towards the brilliant but thinner decorous linearity of Botticelli, when any comparison of the “Mona Lisa’s” hands with those of Leonardo’s “Annunciation” would have warned precisely against such perverse and regressive adulterations.

The interview given to Le Journal des Arts of 27 April, by Ségolène Bergeon Langle read as follows:

Why resign from the Louvre’s scientific advisory committee for the St Anne? “In January 2011 the committee had agreed on a gentle cleaning of late varnishes and the removal of the stains on the Virgin’s cloak. Yet, between July and October 2011 a more pronounced cleaning was done and presented as ‘necessary’, which I objected to. I was then faced with people who would oppose my position, which is technical and not based on aesthetics. My 12 letters [to the Louvre] asking for precisions on some aspects of the cleaning process and on the materials to be used for retouching, remained unanswered. I had to resign (on December 20th, 2011) to be heard just on one specific point: the Gamblin retouching pigments were not to be used since their innocuousness is not proven. Right from the beginning, false ideas have been put forth, like calling ‘repaints’ original retouches by Leonardo in the work’s early stages, or to attribute flaking in the paint layer to the ‘contracting varnish’, a [consequence that was] actually due to the sawing up of the wood [panel]…”

What do you think of the work done? “In my opinion, the precautionary principle hasn’t been respected. We must face the fact that the Virgin’s face is less modelled now. The cleaning should never have gone so far. However, I was happy that the grove [of trees] be preserved and, also, the ground’s material constituents that some ‘felt’ not original (though between January and April 2011 a brown-greenish section of the ground, located below St Anne’s elbow had been removed already). Besides, another matter of much controversy, the whitened layer on Christ Child’s body, has mistakenly been understood as a late varnish [that has] gone mouldy. I’m inclined to believe it was an irreversibly altered [original] glaze and, therefore, I have recommended that it be preserved, but nobody would hear me.”

The current Leonardo exhibition implies that his other paintings in the Louvre should be cleaned also. How do you feel about that? “Just not to do it, by all means! The original flesh paint in the St John-the-Baptist, being rich in oil, displays a significant network of drying cracks and might be fragile in the event of cleaning. For sure, scientific methods are essential but they need sound interpretation and wisdom dually… To date, there is too much boldness originating mistakes and an alarming fascination for infra-red investigation whereby are revealed under-layers that were never meant to be seen.”

Can all the photographs in the world be wrong?
Might anything ever count as a fair demonstration of a restoration-induced injury?
Can no curator or trustee appreciate the inherent physical dangers when allowing restorers, who work with sharp instruments and highly penetrating solvents from the top down, to act upon pictures which artists have built from the bottom up in order to leave their finest and most considered effects exposed at the picture’s surface? Can no one in authority appreciate that every authorised restoration is an accident waiting to happen?
Does no curator ever wonder what has happened to eyebrows and the shading around eyes – and mouths, and nostrils – when pictures are “cleaned” or “restored”? Does no curator appreciate the vital function that shading serves for artists who are attempting to capture from nature, or to evoke imaginatively, a precise and specific personality, state of mind, engagement with the world? Does no curator recognise the tell-tale signs when restorers subvert artistically conjured forms and change the expression on subjects faces?
Would Kenneth Clark, if he were alive today, still consider “Ginevra Benci” and “The Musician” to be Leonardo’s best preserved works – and if not, why not? In the art trade it is recognised that the best preserved works are those that have been preserved least often by “conservators” and “restorers”. Why do people who are charged with protecting art in within the museum service so often take a contrary view? What supports their apparent belief that a much or a radically restored work may count as a “best preserved” specimen?
They all use the words freely, but do any Leonardo scholars, or Leonardo exhibition organisers, truly comprehend the vital conceptual connection between an artist’s system of illusionistic shading and the forms that sculptors literally build? Are any scholars prepared to discuss the manifest changes to Leonardo’s works that emerge in each successive monograph? The elephant in the art restoration room is this: while photography and book reproduction methods improve ceaselessly (see in particular the excellent and instructively enlarged photographs in Giovanni Villa’s Leonardo da Vinci – Painter, The Complete Works), authors themselves habitually refrain from discussing the nature of the often profoundly altered states to which their photographs testify. Ségolène Bergeon Langle, a conservation scientist, has bravely lifted the lid. Will others now discuss what lies below?

Another Restored Leonardo, Another Sponsored Celebration – Ferragamo at the Louvre…

The penny dropped last week in Paris: museum picture restoration is becoming a money-making machine in which the artistic sums may not necessarily add up. The Louvre’s restored Leonardo “Virgin and Child with St. Anne” re-appeared in a series of openings for a swish exhibition-of-celebration, “La Sainte Anne l’ultime chef-d’oeuvre de Léonardo de Vinci”, sponsored by the Italian fashion house Salvatore Ferragamo (whose 2012 fashion show is to be held within the Louvre). The official defences of the restoration are found in the exhibition literature and in a DVD film (“Leonardo de Vinci The Restoration of the Century”) celebrating “The spectacular operation, the likes of which occurs only once a century”. Although there may be a touch of “The Official” in the film, acknowledgement is certainly made of opposition to the course of the restoration that came from within the advisory committee itself. Jean-Pierre Cuzin, the former director of paintings at the Louvre, is seen to speak with great eloquence on the option of, essentially, leaving well enough alone. Reference is also made to wider opposition that was reported in what is described as “a virulent press campaign”. The organisation of the exhibition itself is seen to testify to the rapid growth of mutual support systems within the international museum community. At the same time, we can now better gauge the restoration’s artistic consequences and better appreciate why two eminent art authorities, Ségolène Bergeon Langle, the former director of conservation for the Louvre and France’s national museums, and Jean-Pierre Cuzin, resigned from the restoration’s international advisory committee.

As with the Credit Suisse sponsored exhibition “Leonardo da Vinci – Painter at the Court of Milan” which gathered £1.5bn worth of Leonardos in celebration of the National Gallery’s restored “Virgin of the Rocks” (see Figs. 17 & 18), this Ferragamo/Louvre exhibition has drawn masterpieces by Raphael, Michelangelo, Pontormo, Andrea del Sarto and others. The National Gallery (two of whose staff members served on the St. Anne restoration’s international advisory committee) loaned its hitherto unloanable Leonardo “Burlington House Cartoon” in a straight swap for the Louvre’s earlier loan of Leonardo’s original “Virgin of the Rocks” to the London Leonardo-fest. It would seem that in this international bonanza, one restored Leonardo begets another and each begets a plumply lucrative exhibition and catalogue. The current escalation in travel and restoration risks for works of art is terrifying.

The Louvre’s current exhibition is said by the curator, Vincent Delieuvin, to comprise “a science workshop”. But this “workshop” could not inform the treatment of the painting because it followed, not preceded, the restoration. Moreover, the exhibition itself imposed a guillotine on the restoration. Members of the international advisory committee who wished for more tests, for more consideration of vexing issues, felt thwarted by the Louvre’s need to finish the restoration in time for the arrival of the stupendous borrowed treasures. The cumulative assembled testimony of the exhibition’s many borrowed copies and derivatives of the “St. Anne” might well have been instructive, but, not having been seen, it finds no reflection in the restored Leonardo which artistically has pulled away from its own off-spring (see Figs. 13-16). Delieuvin’s reported twin claims that the restoration “is a true resurrection of the ‘St. Anne’” and that “The painting has recovered a depth and a relief almost like sculpture, with an intense palette of lapis lazuli blue, lacquer red, grays and vibrant browns”, seem both rather tastelessly hyperbolic and at variance with visual evidence (- see right).

Certain structural stresses in the over-heating art economy have become visible. At the exhibition’s epicentre the “Burlington House Cartoon” and the “St. Anne” (for which picture the drawing was a study), have been brought together side by side in a spectacular but counter-productive coup de théâtre (see Figs. 13 & 14). The drawn study, now discoloured but sombrely potent in a magnificently worthy black frame, conjures a breath-taking orchestration of monumentally poetic forms, forms that rightly have been seen to rival the pedimental female groupings of the Parthenon sculptures. Since the Second World War there has been no drawing in existence to rival this fragile and brittle manifestation of the grandeur of Leonardo’s thoughts. (If lost – and in recent years lorries have been burnt-out in the Channel Tunnel and a ferry and its lorry cargo was lost in the Channel – no insurance money or state indemnity could acquire another of its kind.) In contrast, the restoration-weakened “St. Anne”, with its now arbitrarily floating, obtrusively abstract and glitzy lapis lazuli blue drapery, has departed from its formerly-realised self, as the adjacent cartoon and the exhibition’s many derivative pictures mutely testify. To see strong colours subsumed within tight sculpturally integrated groups, we must now look to derivatives of Leonardo rather than to their progenitor (see Figs. 15 & 16).

As if to inoculate the exhibition viewer against this back-firing juxtaposition, the wall immediately opposite the cartoon and the “St. Anne” carries a portentous notice headed “A fundamental restoration”:

A fundamental restoration of Leonardo da Vinci’s St Anne was initially envisaged in the 1990s when a few quite conclusive cleaning tests were carried out.

The picture’s dull appearance, its hues discoloured and distorted by numerous repaintings of the sky and the Virgin Mary’s blue mantle, demanded the intervention that finally began in 2009. Minute bulges, very probably caused by the stress exerted on the picture layer by the hardening of old restoration varnishes rendered the restoration inevitable.

Preceded by an exceptional series of preliminary examinations and scientific imagery analyses carried out by the laboratories at the Centre de recherche et de restauration des musées de France (C2RMF) and generously financed by Mr Barry Lam, the restoration itself began late in 2010. The restorer, Cinzia Pasquali, was chosen following an invitation to tender and worked for more than a year at the C2RMF in the painting workshop in the Pavillon de Flore.

The restoration comprised two principle problems: the removal of the discordant repaintings, some resulting from very ancient and thick accumulations of retouches, the thinning of restoration varnishes oxidised and deteriorated by too many partial cleanings, the moving of excess varnish from one area to another using solvents, retouches and refixings down the centuries throughout its long history, the picture had obviously been devarnished and revarnished many times but fortunately the picture layer had been sufficient robust to resist this. The extremely irregular and oxidised state of the surviving varnishes distorted all the tints and, by a well-known physical effect, ‘decolourised’ and yellowed the original hues.

The gradual thinning of these varnishes to a uniform level was therefore the restoration’s major challenge. During this process, resin analyses and measurements of varnish thickness, conducted by new techniques developed at the C2RMF enabled an extremely precise approach to the thinning, which had to be undertaken delicately, both to preserve a degree of patina on the picture and protect the painting itself from any contact with the solvents used. This extremely gentle cleaning process revealed a painting in vivid colours and resuscitated the splendid lapis lazuli blues and refined violet reds and crimson kermes gum lacquer.”

In this classic museum PR conflation of aesthetic and conservation “needs”, we are variously told that aesthetic changes had been necessary on urgent conservation grounds; that the restoration was “envisaged” some time ago and that this aspiration had been reinforced by the picture itself whose dull appearance “demanded” a restoration. Meeting this demand from the inanimate is said to have been made “inevitable” by a mysterious conservation ailment in the form of “minute bulges” which “very probably” were being caused by the varnish itself.

“Very probably” is a distinctly weasel-phrase and seemed the more so because Ségolène Bergeon Langle had very recently pointed out that the minute manifestations were confined to a single board (which had been badly cut when first made) within the panel, and therefore could not have derived from overall varnishes which some were itching to remove. This analysis of the actual cause was accepted on the DVD film where it was claimed that the restoration had had to proceed because of “lifting due to contraction of the wooden panel”. That raised the larger restoration question: if the varnish was not causing the lifting, was there any conservation reason for removing it at all? A frankly negative admission on that point would, of course, have greatly strengthened the position of the “moderates” on the advisory committee who were, under any circumstances, urging restraint and caution. We now hear that not only is it admitted that the liftings of paint were indeed caused by this plank, but also that they had easily been repaired locally. In hope of preventing future liftings, the panel painting is to be encased in framing that will incorporate a suitable micro-climate designed to stabilise the offending wood. On the face of it, this is good news but, in today’s museum practice, a risk removed often seems to make space for another to be incurred. And, sure enough, we also hear it is now thought that, with the provision of its own micro-climate, this great picture can be regarded as safely peripatetic – and that as such it is to be despatched in the first instance to an annexe of the Louvre at Lens, in northern France. But then where next – Tokyo? Dubai? California? And on what tariff? Perhaps in addition to adding this “restoration of the century” to our list of cleanings sold on misleading conservation-necessity prospectuses, the picture should also be put on our Now At Grave Risk of Travel Injuries category? We trust that the Louvre authorities will amend their misleading wall notice on the restoration.

The material on the picture’s surface is said to have been the accumulated product of many and various previous restorations (some with caustic substances), throughout all of which Leonardo’s original paint had suffered no injury. What chance, therefore, could the last restoration’s highly advanced, “extremely precise” techniques have produced anything other than an “extremely gentle” cleaning? Well, first of all, the proof of the pudding is in the appraising of the result – see right. Second, it is never wise to take restorers’ own prognoses at face value. Errors can occur at any point of the restoration process. The suggestion that a uniform layer of varnish had been left in place might surprise members of the international advisory committee who had been under the impression that varying thicknesses of varnish would be left in place according to specific needs for caution (as with the especially vulnerable face of “St. Anne” – see right).

Further, questions arise in terms of conservation methodological practice. In restorations, paintings are stripped down and then reassembled by repainting. Where, then, are the detailed photographic sequences showing the painting before cleaning; after cleaning but before retouching; and, after cleaning and retouching? Without such hard visual documents the path of the restoration cannot be retraced. It was only when the National Gallery kindly provided such photographs that we were able to identify an unacknowledged change that had been made to the angel’s mouth in the London “Virgin of the Rocks” (see comments at Figs. 17 & 18).

In the two versions of the Louvre exhibition catalogue (one of 52 pages at 8 Euros and one of 448 pages at 45 Euros) there are not even any facing images showing the picture before and after restoration. Such a pairing is found in the (excellent) Beaux Arts special “Léonard de Vinci – Les secrets d’un génie” at 6.90 Euros (a similar comparison is shown here in Figs. 14 & 16). There is also a helpful before and after restoration record of the National Gallery’s “Virgin of the Rocks” (see Figs. 17 & 18).

The Louvre and the National Gallery leonardo restorations share a common methodological feature: in both cases it is said that old varnishes were thinned but not completely removed. This claim creates a conundrum because in both cases changes have taken place which seem inexplicable in terms of a mere thinning of varnish. When explanations are sought or when appraisals are attempted, restoration authorities sometimes take fright, retreating behind claims that theirs is a highly specialised technical field whose mysteries are simply unfathomable to outsiders. Restorers themselves often don the proverbial doctors’ white coat and claim to have acted on not aesthetic grounds at all but on (quasi-) medical ones. For the “St. Anne” restorer, Cinzia Pasquali, this restoration was not made for aesthetic reasons. Instead: “This was about caring for a sick patient. From the conservation point of view we had to intervene, primarily to address a cracking of the varnish that could leave the paint exposed to damage.” Well, we now know that in this particular case the patient was not as sick as had been thought. But more importantly, we should remember at all times that works of art are made by people to be looked at by people. They are not created as laboratory specimens. Artists work with materials so as to produce values and relationships between values. No scientific test can analyse a value, let alone an inter-related group of values. To its maker, the professional test of a work of art is how it looks – the painter stops working precisely when the picture looks right.

In the realm of art and away from corporately funded museum politics, the ultimate test of a restoration is also how it looks – but that is to say, not how it strikes the passing viewer (who may or may not be thrilled by solvent-brightened colours) but how it looks now as compared with how it looked previously; how it looked not just immediately prior to restoration but in its successively recorded history; and, most especially, how it looked the last time it was cleaned. If picture cleanings did no harm, if they were as simple and non-destructive as cleaning a window, each restored work would return to its appearance when last cleaned, and there would be no surprises, “discoveries”, “revelations”, “restorations of the century” – or controversies. While no one ever berates a window cleaner for ruining the views, restorations irreversibly change a picture’s “view” on to the world. Restoration is a one-way street that runs away from history, away from the original work.

All cleaning controversies turn on the extent to which pictures suffer during restoration. Even among those who authorise restorations, some concede that there are losses as well as gains and frankly admit to seeking the best trade-off between improved legibility and pictorial injury. Defensive restorers insist that pictures cannot be harmed by their own “advanced”, “gentle” and “scientifically underpinned” methods. Making a fetish of the “safety” and the “science” of restoration methods attempts to shelve restorers responsibility to identify and account for all material and aesthetic changes. Given that all restorers’ methods cannot be superior, none should be held beyond question. With the physical alteration of art, aesthetic appraisal is essential to scholarship and art’s protection. In appraising restorations, the comparison of like with like is of the essence.

In visual arts, appraisals are necessarily made by visual comparisons. Pictures are made by eye, hand and mind, to be viewed by eye and mind. Because each cleaning destroys the earlier state, comparisons can only be made between pre and post-restoration photographs. While straightforward cleaning might always be expected to achieve a greater vivacity of pictorial effect, it should never be made at the expense of the pictorial relationships, patterns, or gradations made in the service of modelling, that can be seen to reside in the uncleaned work. If the relationships can be seen it is because they are there – whatever chemical analyses might suggest to the contrary. The aesthetic production of pictorial values by artists is the proper science of art. Unfortunately, in such terms, the values that were formerly evident in this great picture seem not to have fared well in this last cleaning.

Above, Fig. 1: Leonardo da Vinci, “Virgin and Child with St. Anne”, detail, before cleaning. Note the artist’s very selective and artfully focussed disposition of his brightest lights, and, at the same time, the extremely subtle but sculpturally effective modelling of the Child’s right shoulder and arm. Note too, the careful placement of tonal values throughout this grouping and how successfully these values contribute to a general sense of sculptural placement in space – for example, how the Child’s left forearm recedes behind the bright wooly top of the lamb’s head, and how appreciably it recedes from the Child’s nearer right arm.
Above, Fig. 2: Leonardo da Vinci, “Virgin and Child with St. Anne”, detail, after cleaning.
How to explain the differences between these two greyscale versions above, of Figs. 3 and 4 below? It has been said that the restorer left a thin layer of varnish over the paint throughout the picture. It is hard, on the face of it and given the scale and nature of the changes that took place in this single restoration, to see how they might have resulted from a reduction rather than an elimination of the varnish (but see below). And it is hard, too, to see how a restorer, cleaning freely by hand with nothing more precise than a cotton wool swab (evidently dragged not rolled in this instance) might differentiate perfectly between the lowest level of a varnish and the upper level of an old glaze of similar colour and tonality at every point. When previous restorers had applied their varnishes, often, presumably, after harsh cleanings, would those then-new, solvent-saturated varnishes not have integrated themselves to any degree within whatever material was to hand?
One question that might always be borne in mind when evaluating pre and post-cleaning states, is whether or not the cleaned (altered) state looks more or less characteristic of the artist’s known traits. (This might be held a perilously subjective notion to conservators of a certain “scientific” bent, but without such an artistic navigational system, how might any restorer proceed?)
Does this after-treatment Fig. 2 detail look more Leonardesque than the before treatment detail at Fig. 1? It is hard to see how this question could be answered in the affirmative. The melting of the Child’s limbs into and out of the artist’s light in Fig. 1 seems quintessentially Leonardesque, while the after-cleaning state of Fig. 2 might be thought rather more Michelangesque by comparison. A key difference between these two great Renaissance figures (and sometime rivals) was that Michelangelo was not averse to autonomously forceful contours. Leonardo, of course, wished to out-sculpt the great sculptor with shaded simulations of form on the picture plane; with forms disposed within an envelope of space and light that was entirely of his own shaping and in no way dependent on the contingencies of the real world in which sculptors’ productions must always take their chances. The existence of the surface upon which paint was applied was a fact to be denied or concealed by the sheer force of artistry. One consequence of this cleaning is that the painting’s picture surface comes further to the fore. The restorer, Cinzia Pasquali, attributes this to the fact that although the work was known to be unfinished, “now we can actually see it”, as if that might be considered some kind of gain, but anything that causes the picture surface to compete for attention with the intended illusion upon it can hardly be thought characteristic of Leonardo’s wishes or intentions, and anything that causes a picture to seem unfinished and less resolved than previously was the case, might more realistically be taken as an aesthetic alarm call than as a vindication of raw method.
Above, Fig. 3: Leonardo da Vinci, “Virgin and Child with St. Anne”, detail, before cleaning.
Work on this section of the painting produced one of the strongest and most keenly contested controversies within the international advisory committee. A “varnish” on the Child’s body was taken by the restorer (and others) to be an earlier restorer’s decayed varnish. This reading was challenged by the student of Leonardo’s painting technique, Jacques Franck, who noted that this material had contributed to the modelling of the Child to a substantial degree and in a manner that went beyond any straightforward varnish layer. He felt, therefore, that it should be preserved until no doubt existed about its precise function and date of making. He and others of this opinion called for the disputed coating to be revived rather than removed, but they were over-ruled on the committee. Analytical tests were made on the material and these were said to have proved on chemical grounds that the material taken to be constructive orginal glazing by Leonardo was in fact only a later varnish. But if this chemical analysis is held to have provided an indisputable basis for excluding the possibility that the material was original, then it is incumbent upon those who removed it to explain how the various apparently artistic effects that it had contributed, had been achieved. In a nutshell the problem is: How might an overall “varnish” as opposed to a glazed layer, contribute differently in local areas that happen to coincide with discrete parts within an artist’s design? In effect, this is the same challenge that we mounted over two decades ago to the restorers at the Sistine Chapel who held that sculpturally-enhancing shadows on Michelangelo’s frescoes were the happy consequence of soot from candle smoke that had accumulated on the ceiling over many centuries.
Above, Fig. 4: Leonardo da Vinci, “Virgin and Child with St. Anne”, detail, after cleaning. Visually, it would seem clear that the ground around the lamb’s tail has been in effect “scoured”; that darkened passages which threw the lamb into relief and prominence have been in effect “abraded”. Is it possible that a mere thinning of an overall varnish could have been responsible for such a transition?
Above, Fig. 5: Leonardo da Vinci, “Virgin and Child with St. Anne”, detail (St. Anne), before cleaning.
Above, Fig. 6: Leonardo da Vinci, “Virgin and Child with St. Anne”, detail (St. Anne), after cleaning. The changes in this face can only thought alarming and deleterious. Vincent Delieuvin’s claim that cleaning has enhanced the sculptural effects of the picture seems plain wrong. For any draughtsman or sculptor, the image at Fig. 5 would have to be considered to hold more “information” than that at Fig. 6. The shadows contribute to a far greater sense of sculptural relief and surface relationships. One might say that the cleaned state now appears to be modelled in shallower relief than that found before treatment. Before the cleaning, the plaited braid of hair running over the top of the head, partook of a general system of shading. After cleaning it has emerged generally lighter and, on the viewer’s left side, no longer tucks into the general ensemble that comprises the more shaded side of the head. Moreover, of the shading on the face, it can immediately be noted that a certain transparency has been introduced – it is now possible to see under St. Anne’s (true) right eye, an earlier positioning of the iris by Leonardo. It is a commonly encountered consequence of picture cleanings that they take works further towards the condition of transparency that is seen in infra-red photographs, where the light penetrates the surface of the paint. While that kind of “imaging” is very useful in terms of identifying earlier stages in a work’s genesis and, specifically, in identifying an artist’s own under-drawing, it cannot be a good thing for works of art themselves to be rendered transparent.
Above, Fig. 7: Leonardo da Vinci, “Virgin and Child with St. Anne”, detail (St. Anne), before cleaning.
Above, Fig. 8: Leonardo da Vinci, “Virgin and Child with St. Anne”, detail (St. Anne), after cleaning. This issue and the artistic dangers of increased transparency had been raised on the international advisory committee by Jacques Franck who had urged that a sufficiency of varnish be left on the face of St. Anne to prevent the inevitable consequence of age-induced transparency in Leonardo’s paintwork from emerging. He has described the peculiarly heightened dangers that were to be expected because of Leonardo’s method on flesh passages at that late stage in his career (when the “Mona lisa” was being produced). He paraphrases his submissions to the committee on the constructive use of “velatura” in the St. Anne head in the following terms:
In Leonardo’s time, those ‘velature’ were meant to interplay optically with the undermodelling and a more roughly worked state of the image. It resulted in opalescent flesh tones linked to the shadows very gradually, thus producing the typical smoky effect called “sfumato” in these sections. The ageing of the binding agent through time has made the opalescent micro-layers become increasingly transparent: details like the eyebrows, some sharp accents in the mouth, in the nose’s end seem to have been executed in the final state of the Saint’s head but have not. They are parts of the underdrawing that are emerging in the visible light due to increased transparency now.
The same with the undermodelling. To date, the soft transitions having lessened markedly, the contrasts between light and shade are much stronger, inevitably so. More microns of old brown varnish left [in place] would have compensated for the now missing opalescent subtleties of Leonardo’s “sfumato”. Hence the difference to be observed between before and after cleaning.
The Louvre was advised by me not to thin too much for that very reason. Leonardo’s subtleties need a substantial ‘veil’ of old varnish left over them, a situation clearly respected by Alfio del Serra in cleaning [Leonardo's] Annunciation in the Uffizi, for the picture’s atmospheric effect is beautifully preserved.”
Above, Fig. 9: Leonardo da Vinci, “Virgin and Child with St. Anne”, detail (St. Anne), before cleaning.
Above, Fig. 10: Leonardo da Vinci, “Virgin and Child with St. Anne”, detail (St. Anne), after cleaning. One sees in this comparison of the eyes, not only the emerged iris but also a substantial degree of lost shading around the eyes. This is very commonly encountered in restored faces. The eye is best understood anatomically as a ball set in a hollow (a hollow that is formed by the brow/nose/cheekbone configuration), and its surface is only made visible through lids that close for protection and during sleep. The “eye” that is defined by the aperture of the opened lids is properly to be understood as a part of the surface of the larger eyeball. The relationships between these component parts are very distinctive to individual heads (or to the idealised “types” of heads devised by artists). Anything that reduces the original artist’s construction of those relationships (made by shading essentially) is extremely harmful to the “plastic” properties of the head as well as to its characteristic expression. A commonly encountered feature of restored faces is that the shading around the eye, which “sets” it properly in its recessed protective zone, is so diminished that the more precisely delineated parts – the shapes of the eyelid apertures and the iris/pupil – of the eye become more apparent, become over emphatically drawn.
With regard to the level of cleaning that is said to occurred on the St. Anne, Franck had been assured that varnish would be left in place to a thickness of 18 to 20 microns. A micron is only one-thousandth of a millimetre or 0.001 mm. It might be wondered how a restorer working with solvent-laden cotton wool swabs (as seen in use on the DVD film, for example) might ever be able reliably and predictably to operate evenly to such ultra-fine tolerances. In the event, Franck was told that on the St. Anne the level of varnish that had been retained was of only 12 – not 18 to 20 – microns depth, or in other words of 0.012mm. This raises the question: Was this, as had been promised, the area of greatest varnish thickness that was left in place, or was this, in fact, the “uniform level” to which the painting had been cleaned throughout, as is described in the exhibition on the wall notice?
Above, Fig. 11: Leonardo da Vinci, “Virgin and Child with St. Anne”, detail (St. Anne), before cleaning.
Above, Fig. 12: Leonardo da Vinci, “Virgin and Child with St. Anne”, detail (St. Anne), after cleaning. It would seem inconceivable, to any sculptor’s trained-eye that this section of the face, after cleaning, might be considered to enjoy enhanced sculptural values. In purely formal terms, what is seen here is an advance and an expansion of the lights at the expense of the darks – which darks had comprised in this working method the “constructive” component of Leonardo’s “modelling” on the light ground of his picture. The lights had not been painted as values, they were merely the sections of ground left unmodified by Leonardo’s meltingly applied shadows.

As with the Louvre’s St. Anne, the varnish (which had been described as having come to constitute a threat to, as well as a disfigurement of, the paint) was said to have been thinned not removed. Indeed, when shown the painting part-cleaned, and when it was lit with an ultra-violet lamp, remains of (patchy) varnish were to be seen on the picture. Against that evidence, we face the problem of how the changes that manifestly occurred (as seen above) could have arisen. For example, how was the angel’s mouth changed if it remained under a film of varnish? What accounts for the fact that after the last cleaning the picture did not return to anything like its condition when previously cleaned sixty years before? Specifically, what accounts for the great lightening of the sky seen in the top right, as opposed to the sky seen on the left? What accounts for the great change in the Virgin’s blue robes?

Black is a Colour

We reported in an early Journal that Anna Somers Cocks, when editor of The Art Newspaper, had observed that Frans Hals employed as many as six tones of black and that these were “too often deadened by bad cleaning”. This prompted a response from a painter colleague.

Iain Walker wrote:

Anna Somers Cocks’ observation that Frans Hals painted with up to six tones of black reminded me of another appraisal made some years ago when Hals was being shown at the Royal Academy. An eminent art critic noted in his review of the exhibition that Vincent van Gogh had claimed to have counted no fewer than 28 different blacks in a Hals painting. The observation, the critic accepted, may have indicated Vincent’s preoccupation with the picture but it could not have been so because research had revealed that at that date there were only six blacks in production. Many readers may have concluded that poor Vincent had got it wrong again, and that this was a critic who did his homework.

At the time of this review, a project exploring the nature of black and the assumptions we have of it, was being conducted with the first year students at the City and Guilds of London Art School in Kennington. To this end, one side of the studio had been painted black throughout and filled with black objects and materials: black cottons, velvets and silks, as well as a numerous household objects that were painted or sprayed with matt or gloss paint. Coal and soot were also used.

The task given to the students was to make a perceptually accurate painting of a section of the studio without using any black paints. They met this requirement by mixing their own blacks from the colours contained in their paint kits. It was pointed out that Francis Bacon often produced a black by mixing sap green with alizarin crimson. The students also made use of Prussian blue, cobalt, burnt umber, violet etc. Their studies swiftly established that it was entirely possible to make an optically accurate transcription of a black set-up containing many black objects without ever having recourse to any commercially available black paint.

In painting, all colours and tones are relative. Margaret Meade cites the Eskimos as having 17 words for white. When confronting an all black set-up, it soon becomes apparent that there are greenish blacks, reddish blacks, bluish blacks and so forth. Theoretically, there may be a black which absorbs all incident radiation but even a material as black as soot apparently reflects 3% of incident light. Couple this fact with the effect of “simultaneous contrast” and it is hardly surprising that most painters think of black – and white – as colours in their own right and not just as means of creating a tonal range in a painting, as there other ways to do this.

I recall the above as a demonstration of how well-meaning academic research, although possibly correct in one way, can also be misleading and harmful when applied to painterly practice.

“I remember visiting the Delacroix house in Paris, where they have a palette on which he’d mixed a whole row of grey tones, each looking like a pearl, and each mixed from colour, not from black and white. Instead of darkening yellow with black, he darkened yellow with purple.”
From Artists on Art, Martin Gayford, The Daily Telegraph, 13 January 2001.
SEEING NATURE’S PALETTE:
“I cannot help thinking that something important is being lost and that we ought to refresh our eyes with the more subtle harmonies for which they were designed. The dead of winter is the time to do this. For life has retreated, leaving its many colours half-hidden but perceivable, and the landscape is filled with a subtle counterpoint that could never feature on the telly. The lesson so patiently taught by Corot, Turner and Cézanne – that no natural object is truly monochrome, and that even in the blackest thicket can be discovered all the colours of the palette – is repeated by winter. And that is why there is no better time to visit the country, to walk or ride in the fields and to take the chance of the weather for the sake of the eyes…It is an interesting exercise to stare into a dark, denuded hegerow and count the colours. Soon you will come to see that this unassuming, unclamorous thing could not be transcribed in paint without using the entire pallete: every shade of red and blue, from salmon pink to scarlet, and from deepest indigo to pale forget-me-not, is lurking there, recuperating from the light of summer. And as you watch these hues glimmering like embers you come to understand the myster of colour: how red excludes green and yellow blue; how white is somehow not a colour at all and the metal shades are like glosses in which colours are trapped and made invisible. These strange phenomena are not explained by the physics of light – a fact which Goethe noticed, and which led him to compose his great treatise on colour. They are not facts about things, but about us seeing things. Pondering them we are also pondering the mystery of consciousness. How is it that the world not only is, but is also revealed? Why was it not content just to be?”

The Perpetual Restoration of Leonardo’s Last Supper, Part 2: A traumatic production of “a different Leonardo

The unhappy $8m Olivetti-sponsored restoration of Leonardo’s Last Supper began in 1977 with a repair of small flakes of detaching paint. It morphed, on very grand institutional technical advice, into a promised liberation of all of Leonardo’s surviving original paintwork. It ended after twenty-two years amidst widespread recriminations and as a distinctly mongrel work showing alarmingly little original paint and very much alien “compensatory” and “reintegrating” new paint.

Prospective major restorations are often presented as elegant technical answers to some urgent conservation necessity the resolution of which promises magnificent artistic gains. In reality, the interface between technical intervention and artistic outcomes constitutes art restoration’s fault-line and does so in a field that is notoriously subject to the law of unanticipated consequences. One of the commonest surprises is how greatly the coherence of a work had depended on earlier restoration repairs that were removed on the grounds of being alien impurities. Like Humpty Dumpty, radically stripped works often prove to be wrecks that have to put back together again and many a restorer discovers – too late – that it is easier to take to pieces than to reassemble [see Endnote 1]. The resulting changes made during restorations are often presented as “discoveries”, “recoveries” or “recuperations” when on close examination they prove to have been plain errors. One such unwarranted, unsupported, insupportable case is shown here.

Towards the end, the restorer, Pinin Brambilla Barcilon, expressed the hope (Art News March 1995) that her restoration might be the last because: “The less you restore a work of art, the better its chances of survival. Each time you touch a work, it suffers a trauma, no matter how carefully you operate.” In November 1998 the Art Newspaper reported that when Mrs Brambilla was restoring a crucifixion on the wall opposite the Last Supper in 1978, she noticed that “fragments of painting were peeling off Leonardo’s work before her eyes.” The Guardian of July 21 1997 reported she had noticed “bits of painting falling from the Last Supper” and that after experts from Italy’s central institute for restoration in Rome (Istituto Centrale di Restauro) had been called in “the decision to restore the painting was swiftly taken”. Too swiftly, many Italian experts believed.

Although conservation necessities are sometimes exaggerated [see Endnote 2], with paint losses, determining the extent, cause, and remedy must always be the top priority – the equivalent of fixing a building’s leaking roof. As seen in Part 1, when the Last Supper was disintegrating to the touch after the Second World War, the then restorer, Mauro Pelliccioli, fixed the problem by embedding the paint in litres of shellac. He also won some critical praise for uncovering most of Leonardo’s own surviving paint from restorers’ over-paint. Crucially, however, he tackled the disintegrating paint first (during 1947-49). Only when the shellac was settled and the paint completely secure did he begin scraping off restorers’ repainting (during 1952-54). In this most recent restoration, despite the problem of paint detachment, work began with an intended systematic removal of the remaining repaints.

Effectively, in the last restoration the authorities undertook an all-or-nothing gamble with a masterpiece. Against the certainty that shedding the old would be disruptive of the familiar and the still-surviving, they bet that the recovery of some more fragmentary, talismanic relics of Leonardo’s paintwork would outweigh the scale of accompanying losses and newly exposed bare wall. This presumptuous naivety was to prove disastrously wrong-headed. First, as scientific tests of paint fragments (published in Studies in Conservation, August 1979) were to warn, the distinction between original paint and later restorers’ overpaint was not at all easy to establish: “the dividing line is much less clear cut”. (This was hardly surprising given the work’s earlier exposure to corrosive cleaning agents and heated metal rollers.) Second, Pelliccioli had already uncovered most (two thirds, he believed) of what was taken to be Leonardo’s surviving paint. While there was not all that much more to recover, there was, artistically, still very much to lose. Pelliccioli had left repaints in place precisely where they covered only bare wall – which is to say, where they held the image together.

The paradoxical consequence of this pursuit of original material was that the old ill-preserved yet somehow-maintained “theatrical” illusion that Leonardo had originally created was greatly undermined. One narrow specialised purist concern for what was “original” and “authentic” material was set against another larger more elusive aesthetic/artistic concern for what had been intended; for what was yet struggling to survive. Achieving the liberation of fragmentary and injured archaeological material imperfectly adhering to a damaged moisture-prone vertical surface came at the cost of eliminating all that had maintained and prolonged Leonardo’s decaying but originally mesmerising artistic illusion incorporated into the space and fabric of a large room. (Kenneth Clark had spoken fondly of “these ghostly stains upon the wall”.) The work was remorselessly stripped down to the sum total of all previously accumulated injuries in order that the resulting wreck might then be put back into some presentable aesthetic form more suited to today’s tastes. The ideological/art historical rationale offered for this purgative exercise was that every age has the right to make its own Leonardo…that the Leonardos that had come down to us from the past were somehow deficient, obsolete, culturally-contaminated; that we now simply know better. The preposterous nature and Futurist flavour of this relativist conceit (“Every previous generation has erred, we, standing outside of history – or at its end – will now get things right”) might have been held self-evident. Leo Steinberg, evidently unsettled by this recent spasm of historical/aesthetic cleansing, quoted Jonathan Swift: “Last week I saw a woman flayed, and you will hardly believe how much it altered her person for the worse.” (“Leonardo’s Incessant Last Supper”, 2001.)

The purist shedding of earlier repaints regardless of their antiquity and artistic functions, necessarily guaranteed that Leonardo’s work would be “altered considerably”, as Carlo Bertelli, the then director of the restoration, acknowledged in the catalogue to the 1983 Washington National Gallery of Art exhibition of Leonardo’s studies for the Last Supper. A later defender of the restoration, Giovanni Romano, not only applauded the creation of “a different Leonardo” during “a great restoration” (Il Giornale dell’arte, April 1999) but fawningly added that he would be “satisfied with a restoration of this sort every year.” Throughout this era of vaultingly high ambition, the restoration community needed the biggest possible “sell”: nothing less than a “New Michelangelo” was said to have emerged during the Sistine Chapel ceiling restoration. It became a commonplace that revolutionary restoration “discoveries” required the very “rewriting of art history”.

There is no mystery about how the latest calamity came about. In the 1983 catalogue, the Washington National Gallery curator, David Allan Brown, duly relayed the twin official reasons for the restoration: that the paint (which, under a microscope, resembled “the scaly skin of a reptile” ) had not remained secure; and, that Pelliccioli had not removed all earlier repaints. The repaints had to come off because they were now “threatening the stability of the original colour.” Not explained, was how this was so, or how much original paint had been left by Pelliccioli. In the July 2 1995 New York Times, Bertelli recalled having been “certain that there was enough beneath the additions to warrant this restoration”. He added that “Mrs Brambilla and I had examined the surface with a microscope, and we were surprised to see how much of Leonardo’s original work remained”.

In 1983 Allan Brown noted that “The expectation that a considerable portion of the original might survive [had given] a strong impetus to the decision in the late 1970s by the Superintendency of Fine Arts for Lombardy (at that time directed by Franco Russoli) in consultation with the Istituto Centrale di Restauro, to take up again the unfinished work of cleaning the picture.” This would suggest that so strong was the desire to revive and complete Pelliccioli’s unfinished aesthetic programme that the operation was begun even as the technical solution which had originally made that aesthetic objective possible was said to be failing. Whatever gains might have been hoped for or anticipated, by May 1998, Bertelli admitted (in Art News) that “Now we can see only a few square feet [of original Leonardo paint] but they are by the master” and, on a Channel 4 documentary that year (“The Lost Supper”), he characterised Leonardo’s mural as a “ruin” (“una rovina” ). In the November 1998 Art Newspaper Brambilla said, self-contradictorily, that the repaint had had to be removed out of fear that condensation might become trapped between “the artist’s original paint and the successive layers of paint”, and, that constant environmental conservation measures would henceforth be necessary because “the layers of repainting are no longer protecting the original paint.”

Which was the case? If the repaint was protecting the Leonardo paint, what had been causing the original detachments? Given that the 1979 tests mentioned above had established that it was not always possible – even under ideal laboratory conditions – to “decide exactly on the dividing line – both for areas and for layers – between what remains of the original and materials pertaining to later interventions”, how great could the risk have been of moisture insinuating itself between the original and the subsequent paint layers? On whatever technical premises it rested, when the restoration proper began on the better preserved right-hand side of the mural, the attempted removal of all previous restorers’ repaints and consolidations of paint, inevitably constituted a prolonged and sustained assault on the mural’s fabric – as Brambilla herself candidly described in the March 1995 Art News:

Here we have a surface that is completely ruined, disintegrated into tiny scales of colour that are falling off the wall. We have to clean each one of these scales six or seven times with a scalpel, working under a microscope…Here I can clean an area one day and still not be finished, because when the solvent dries it brings out more grime from beneath the surface. I often have to clean the same place a second time, or even a third or a fourth. The top section of the painting is impregnated with glue. The middle is filled with wax. There are six different kinds of plaster and several varnishes lacquers and gums. What worked on the top section doesn’t work in the middle. And what worked in the middle won’t work on the bottom. It’s enough to make a person want to shoot herself.”

Could Pelliccioli’s already failing shellac have survived these repeated traumatic assaults with solvents and scalpels on all the glues, waxes, lacquers and gums within the paint-film? Had some new superior quick-acting consolidant been identified or manufactured? What were the structural consequences of this apparent removal of every atom of previous consolidations of the paint? Brambilla has said of the detaching paint “To re-adhere the fragments we used wax-free shellac in alcohol, the same adhesive as Pelliccioli applied during his intervention of 1947″. So, in other words, just some more of the same. If Brambilla’s best English wax-free shellac lasts no longer than Pelliccioli’s, we might expect another restoration within twenty years or so.

One thing is clear: the technical underpinning of the restoration, and the swiftness with which its unquestionably radically transforming methodology was applied, were both challenged by Italian experts. On July 2 1995 the New York Times reported that Mirella Simonetti, a Bologna-based restorer, protested: “There was never any doubt in their minds. They decided how to proceed without even conducting the proper analyses to determine how much of the original painting remained. They didn’t even submit their findings to an international committee of experts.” The Florence-based diagnostician, Maurizio Seracini, who had been called to examine the Last Supper after the restoration began, complained: “I think that Mrs Brambilla has worked in good faith. But you don’t decide to restore a masterpiece like the ‘Last Supper’ on the basis of what you see under a microscope. It’s simply irresponsible.” Seracini added “I myself have not seen any definitive scientific proof that restoration was really needed.”

That the authorities had not known how much original Leonardo paint might survive had been tacitly acknowledged as early as 1983, when, with the restoration one third completed, David Allan Brown could speak only in relative terms: “By comparison with other, well-preserved murals of the time, Leonardo’s detailed execution is almost entirely lost.” Even when the restoration was eventually finished (or halted) there was no agreement among the protagonists themselves on how much had survived. Carlo Bertelli, the director of the Brera Art Gallery in Milan, who effectively initiated the restoration, put the figure at 20%. Pietro Marani, the prolific Leonardo scholar who advised Brambilla from 1985 and became co-director of the restoration in 1993, once said that “no more than 50%” survived and later more ambiguously claimed that 90% had survived “in parts”. Giuseppe Basile (later the director of the restoration of Giotto’s Arena Chapel frescoes) put it at “about half”. Giorgio Bonsanti, the director of the Florence-based laboratory Opificio delle Pietre Dure, put it at “possibly 20%”. Giovanni Urbani, the director of the Istituto Centrale di Restauro between 1973-83, and the director of the Brancacci Chapel restoration, thought 25% had survived.

In 1989 a Milan town councillor, Maria Bonatti, brought an (unsuccessful) action against the restorer for accelerating the mural’s decay – a charge also made by the painter, essayist and paint materials expert Mario Donizetti, who held that it would “disintegrate more rapidly than before.” Ten years before the restoration ended, in November 1989 the Art Newspaper reported “Over the years work has been stopped repeatedly, sometimes following changes at the helm of the Milanese Soprintendenza and the Instituto in Rome, other times simply to allow the whole project to be reconsidered.” Eventually the proceedings quickened dramatically. In his 2001 book, Leo Steinberg recalled encountering the restorer and three young assistants in 1998 “all huddling at lower left scraping away”. On the cleared wall, “more filling was needed – and it had to be done fast (a deadline had been imposed from on high), so that this must-see tourist attraction would show decent finish to the daily sightseers.”

In 1983 Bertelli had said in National Geographic that Brambilla was taking a week to clean an area the size of a postage stamp. He quoted her professional plaint: “It’s difficult. The work is hard and tiring. It creates much physical tension bending over the microscope. After a few hours my eyes grow blurry. I may come every day for months. Then I must take an extended break. There is also the psychological tension. All the eyes of the world that know Leonardo are watching what I do. Some nights I do not sleep.” The pressure intensified as the restorer inched her way towards the central figure of Christ. In April 1998 the Art Newspaper reported that “Hundreds of tourists (mostly Japanese) last month lined up…to visit Leonardo’s Last Supper. The painting was back on view after having been closed for two months to allow restorers to work on the faces of Christ and the apostles.” That report evidently escaped the attention of the National Gallery’s then director, Neil MacGregor, who wrote in his 2000 BBC book “Seeing Salvation”:

When the latest restoration was unveiled in 1999, all hell broke loose, and the admirably scrupulous restorer in charge was vilified in much of the world’s press…Among the wilder accusations, fears were expressed that the face of Christ had been altered. Happily these proved to be groundless.”

That the unveiling was badly received is beyond dispute, but if vilification was in evidence it was aimed by defenders of the restoration at their critics (see right). The extent to which the face of Christ was altered, and the evolving means by which the restorer came to impose her own distinctive, ahistorical, arguably arbitrary aesthetic reading on the unprecedentedly vast, fully-exposed areas of paint loss in a quest to “bring it back to its original colors and composition”, will be examined in Part 3. Here (right) we examine a single unwarranted change that was made to the design of drapery on Christ’s right arm and then presented as a restoration recovery.

ENDNOTES
[1] In the 1962-64 National Gallery Annual Report, the then director, Sir Philip Hendy, described how with the great Uccello panel from the Battle of San Romano series, the stripping down (which had begun and 1959 and was still ongoing) had exposed a greatly damaged surface. As a result, after its characteristic Gallery “complete cleaning“, it was realised that “To restore scrupulously takes very much longer than to create freely, and the task of pulling the picture together again could have been further prolonged.”
[2] With the restoration of Michelangelo’s Sistine Chapel ceiling it was said in 1986 (six years into the restoration) that “various checks [had] ascertained that in several places minute flecks of colour were lifting” and that this had “necessitated an immediate restoration.” In 1987 it was said that extensive areas of flaking were progressively worsening and threatening an imminently “uncontrollable situation”. By 1988 Vatican spokesmen were claiming that the weight of encrustations upon the paint surface was causing it to break away from its ground. By 1989 it was said that the glues had “shrunk and puckered” causing “scabs” to fall away “pulling pigment with them”. It was said that this “slow destruction by glue-pox” was “the Vatican’s principle motivation for cleaning the ceiling“. When I asked in 1990 how big the puckerings were, a Vatican spokeswoman said “Oh! Some are as big as your hand.” Soon after, in 1991, the problem de-escalated: initial investigations were acknowledged, once more, to have encountered “minute desquamations and loss of pigment.”

Such reports generated public denunciations of the critics. One, by Georgio Bonsanti in the May 1999 Art Newspaper, targeted this organisation:
At the root of the controversy are the declamations of the international brigade, Art Watch International, now nearly ten years old, led by the American art historian James Beck and the English journalist [sic] Michael Daley. These crusaders are convinced that masterpieces are being desecrated by poor restoration all over the world but especially in Italy…”
Bonsanti further claimed that Italy’s restorations were being attacked by outsiders because that country “tolerates dissent”, evidently forgetting that James Beck (a professor of art history at Columbia University, who lived in Italy for part of each year, whose wife was Italian and whose children are half Italian) had been hounded simultaneously in several Italian cities on charges of criminal slander (which carried, in addition to horrendous potential financial penalties, the risk of a three-years jail sentence) for criticising the restoration of a masterly piece of sculpture by the subject of his life-long studies, Jacopo della Quercia. (For Michael Daley’s reply, see “Was it necessary?”, the Art Newspaper, July/August 1999.)
In a more specifically abusive vein Bonsanti alleged that:
All standards of accuracy and correctness were laid aside in the scramble to report the supposedly disastrous restoration of the Last Supper…I am not suggesting that critics should be silenced or that a moratorium is desirable, but criticism should be based on observable fact, it should be a technically competent, well-researched and accurate reaction.”
As it happens, all of our criticisms are based on observable, demonstrable (and photographically reproducible) facts. How else, in visual art, might criticisms proceed? As a case in point we discuss and illustrate below a change that was made to the Last Supper and then presented as one of a number of “noteworthy recoveries” when, manifestly, it was not a recovery but an adulteration.
To judge restorations it is necessary to know what was done and what was said to have been done by those in authority. For many of those of us who had the privilege of seeing from the scaffold what was being done to Leonardo’s work, the experience was alarming. The removal of everything except that which was deemed original Leonardo paint meant that greatly more “not-Leonardo” was emerging than Leonardo. The second consequence of the stripping was that what little original paint survived, was lost in the visual clamour of the surrounding cracked and discoloured wall preparation layers.
It would have been inconceivable to leave the tiny emerging islands and archipelagos of original paint adrift in the vast sea of ruined wall. At close quarters it was evident that this was not only an extreme restoration, it was also methodologically self-defeating in its dogmatic pursuit of “pure” material. As fast as earlier restorers’ paint was eliminated, fresh paint was needed to ameliorate the losses and impart a pale impression of continuity, coherence and legibility (“The goal of pictorial integration was to achieve a sufficient legibility of gesture, pose and modeling” – Brambilla). The purging of paint and the attendant debilitation of imagery gave rise – as is soften the case with radically deconstructing cleanings – to a misconceived, ahistorical reconstruction that altered the design of the picture – in this case, even, that of Christ himself. While doing so in the name of historical authenticty, historical testimony was defied to a degree that beggars belief.
The change in question was made to the sleeve of the tunic on Christ’s right arm. It is shown here at Figs. 5-9, as it appears in the “official” published accounts. As seen in Figs. 6 and 8, the alteration was made with fresh paint to stripped areas. On the “evidence” of some fragments of red paint located in a clearly distressed section of the mural, the sleeve drapery was extended by fresh repainting so as to come to rest on the top of the table which it had originally tucked behind – as countless drawn, engraved and painted copies of the Last Supper testify.
By a fluke of publishing, we can show directly comparative photographs that capture the genesis of this alteration. They are found in two books. The first is Pietro Marani’s sumptuous, large format 1999 “Leonardo da Vinci ~ The Complete Paintings” (hereafter: Marani 1999). In it there is a photograph of Christ (shown here in Figs. 6 & 8). It was taken when the figure had been stripped down and largely but not entirely retouched. The second source is the beautifully photographed and produced 1999 book-of-the-restoration “Leonardo ~ The Last Supper”, by Pinin Brambilla Barcilon and Pietro C. Marani with Antonio Quattrone’s photographs (hereafter: Brambilla/Marani 1999). In this book there is another photograph of the Christ but this time it is after all the retouching had been completed. This plate is seen at Figs. 7 & 9. The differences between the two states are worth a thousand words. But before discussing their testimony in detail, the status of the many copies of the Last Supper should be considered.
We take as fair testimony of Leonardo’s original treatment of the drapery, copies of the Last Supper made in the first eleven decades of its life. Fig. 2 is a detail of an engraving thought to have been made within a couple of years of the Last Supper’s completion. Although primitive in style, it clearly shows that the sleeve drapery is cut off by the table top and does not not rest upon it. Over a century later, Rubens (or an associate) made a copy in ink and wash. Here too the sleeve drapery is cut off by the table.
Above, top left, Fig. 2: Detail of the engraving given to Giavanni Pietro da Birago and thought to be the earliest copy (c. 1500) of the Last Supper which was completed in 1498. This work comprises a visual record of the Last Supper’s appearance before the mural’s notoriously rapid physical decomposition was in train. Enlarged, the clarity of delineation attests to a feature that may not be so evident elsewhere: the (blue) mantle does not yet simply disappear in the zone of shadow behind the table and between the arm and torso (as is already recorded at Fig. 4), but is seen to turn briskly around the waist of Christ.
Above, top right, Fig. 3: Detail of an ink and wash copy given to Rubens or an associate, and of c. 1600-08. It is possible that the Rubens copy may have been made not from Leonardo’s Last Supper in Milan but from the large full-size copy of it seen at Fig. 10. But that copy, too, attests to the drapery being cut off by the table. This table/drapery relationship had thus remained unchanged for more than a century.
Above, Fig. 4: Detail of the 1616 oil on canvas copy by Il Vespino (Andrea Bianchi). This copy had been specifically commissioned in 1612 to record the then condition of the already alarmingly decaying mural.
Above, Fig. 5: Leonardo’s Christ, as seen before the 1977-1999 restoration. It is clear when comparing this state with the copies of the painting shown at Figs. 2, 3, 4, 10 & 11, that in the course of earlier restorations, the drapery of Christ’s right arm had been slimmed down on its inside edge by encroachments of the shaded zone between the table top and the figure.
The key role served by certain copies in the last restoration might be mentioned. Pietro Marani (in Brambilla/Marani 1999) discusses the assorted values of the many and various copies as testimony. He gives a list of fifty principal and “more faithful copies”. Pre-eminent among these are the two full-size oil on canvas copies of the Last Supper. One is by Giampietrino, a student of Leonardo’s (see Fig. 11). It is given to c. 1520. The second is given by Marani (on not very clear grounds) to an anonymous Flemish artist, but it was formerly attributed to another Leonardo follower, Andrea Solario. For convenience we refer to it as the Tongerlo copy, after the Abbey in Belgium which has owned it since 1545. A third large copy is the oil on canvas by Il Vespino, shown above at Fig. 4. At the time of last restoration of the Last Supper the Il Vespino had recently been restored and put on display in Milan at the Ambrosiana.
The two full-size canvases played critical roles in the last restoration. The Tongerlo copy had been damaged in 1929 and was restored in 1932, 1952 and again in the 1990s prior to being housed in what is known as the Da Vinci Museum. The Giampietrino (owned by the Royal Academy) was borrowed as an aid to the last restoration and cleaned to that end by Pinin Brambilla Barcilon. Marani says of the copies generally that their value “cannot be overestimated”. From the full-size Giampietrino and Tongerlo copies, Brambilla had taken tracings – and these, Marani reports (Brambilla/Marani 1999), demonstrated:
…how the painters faithfully traced the most important elements of Leonardo’s work – the heads, hands and other principle outlines of the various figures – but then assembled the pieces into into complete images that did not always take into account the original intervals between the figures and the painted spaces in the mural.”
That the two full-size copies shared essential design properties both with one another as well as with Leonardo’s mural is of the utmost importance. Such a triangulated matching of imagery shows that the Tongerlo and Giampietrino copies were taken directly from the mural itself after completion, and were not taken from cartoons that might have been made in preparation for the painting during the course of which revisions were made. This in turn means that the restorers between 1977 and 1999 had in their possession unquestionably reliable guides to the designs and the component parts of Leonardo’s figures as they had been finished by him on the mural itself – if all three matched, none could be inaccurate. There could be no grounds for departing from the commonly held “principle outlines of the various figures”.
Above, Fig. 6: Christ, as seen (in Marani 1999) before the completion of the 1977-1999 restoration. This illustration captured a curious stage of restoration. We see that after the stripping of earlier restoration repaints, the extensive losses to the blue drapery of the mantle and the red drapery of the tunic had been ameliorated by overall applications, respectively, of lighter blue/grey and lighter red paints. Of critical importance is the fact that at this stage a crescent shaped, as-yet untinted zone, sits unresolved between the red and the blue passages, as if there is confusion about where to place the boundary between the coloured zones of the two draperies. A reason for hesitation is not hard to divine: this untreated area not only sits between the red and the blue draperies, it also also runs down across the table cloth.
Above, Fig. 7: Christ, after the completion of the 1977-1999 restoration (as in Brambilla/Marani 1999). It can now be seen that the junction of draperies at the inside of the red sleeve and the blue mantle in Fig. 3 was moved rightwards by an extension of the pale red paint. But at the same time, this light red retouching has also been carried downwards, overlapping the table cloth before turning upwards so as to terminate behind the wrist, and thereby impart to the sleeve drapery a muff-like (or puffball-like) configuration from the centre of which the forearm now emerges. As well as being an unwarranted falsification of Leonardo’s design, this change insinuates a solecism: in the laws of artistic drapery, material hangs from and partially expresses underlying human forms, it does not provide autonomous enclosing receptacles for them (like pots for a lobster, as it were). As shown below, no authority exists in the painting’s many copies for this change of design.
Above, Fig. 8: An enlarged detail, again showing the sleeve/mantle relationship after some tinted infilling had taken place but before the completion of the restoration. The dark shape in the bottom left corner is the mantle of the apostle John. It would seem that this photograph was taken at the point when the restoration was just about to pass to the left of Christ. It would seem also to confirm that the tinted infills were being made pretty much as the stripping down was taking place. Here we can see that the razor-sharp delineation of the architectural forms is not a happy by-product of the stripping down but is almost entirely a subsequent reconstruction effected with superimposed overall painting on a zone of almost total losses of original paint. It looks as if the tinted brown repaint on the background wall was stopped short of the not-yet stripped drapery of John, thus producing the temporary effect of a coarse outline or halo.
Below, Fig. 9: The section at Fig. 8 after completion of the restoration. Note how the repainted tones on the architecture have been brought to a sharp and precise relationship with the contour of the arm drapery. Is that seeming precision of draughtsmanship authentic or spurious? How well does it compare with the sleeve/wall boundary on the two full-size copies shown below? Of this back wall, Pinin Brambilla Barcilon writes:
The entire wall, however, was characterised by the widespread loss of colour…Once the superficial repaint had been removed, it was clear that we had to press on with cleaning in order to achieve some sort of visual coherence between the back wall and the side walls…Pictorial integration meant that the wall had to be restored using coats of dark toned water colour to define the shadows. Obviously the flakes of original colour remain completely visible…”
Of the sleeve drapery the restorer writes:
Like the mantle, Christ’s robe also required the removal of extensive repaint, as the heavy red tone detracted noticeably from the lovely original vermilion passages. The thick adhesives made the removal particularly difficult, so it progressed with the repeated application of compresses which managed to dissolve the film of glue completely. The cleaning redefined the original articulation of the folds, both at the neckline and at the sleeve cuff. The cuff which had been covered by the mantle’s repaint now revealed beautiful violet flakes, composed of a blue base glazed with a crimson lake to define the shadow area…”
The very concept of “redefining” the original is unsettling if not oxymoronic. Note that while there is excitement at the discovery of “beautiful violet flakes” (as seen through a microscope?) in the stripped down wreckage, there is no mention of the table cloth or discussion of the changed drapery/table relationship. The restorer continues:
Other noteworthy recoveries included…”
Above, Fig. 10: Detail of the Tongerlo Abbey copy of which Steinberg writes:
“…given its size, its high quality, and general accuracy, the Tongerlo copy ranks with the finest surviving testimonies to the near-lost Leonardo.”
Above, Fig. 11: Detail of the large, c. 1520 copy of Leonardo’s Last Supper that is owned by the Royal Academy and attributed to Giampietrino. In the catalogue to the National Gallery’s recent “Leonardo da Vinci – Painter to the Court of Milan” exhibition, Minna Moore Ede wrote:
Given the deteriorated state of Leonardo’s Last Supper mural today, the question of which of the early painted copies can be said to be most faithful to the original is of particular and tantalising importance. Always viewed as among the most accurate is this scale copy by Giampietrino…Believed to have been a live-in apprentice of Leonardo’s during his first Milanese period (probably joining the workshop in the mid 1490s), Giampietrino would have been present during the period when Leonardo was preparing and painting the Last Supper, perhaps even assisting his master.”
When told of our objection to the redrawn sleeve of Christ, Pietro Marani reportedly responded: “A small piece of drapery. Oh, my God.” and contended that Giampietrino might have misunderstood the position of Leonardo’s drapery.

Another Restored Leonardo, Another Sponsored Celebration – Ferragamo at the Louvre…

The penny dropped last week in Paris: museum picture restoration is becoming a money-making machine in which the artistic sums may not necessarily add up. The Louvre’s restored Leonardo “Virgin and Child with St. Anne” re-appeared in a series of openings for a swish exhibition-of-celebration, “La Sainte Anne l’ultime chef-d’oeuvre de Léonardo de Vinci”, sponsored by the Italian fashion house Salvatore Ferragamo (whose 2012 fashion show is to be held within the Louvre). The official defences of the restoration are found in the exhibition literature and in a DVD film (“Leonardo de Vinci The Restoration of the Century”) celebrating “The spectacular operation, the likes of which occurs only once a century”. Although there may be a touch of “The Official” in the film, acknowledgement is certainly made of opposition to the course of the restoration that came from within the advisory committee itself. Jean-Pierre Cuzin, the former director of paintings at the Louvre, is seen to speak with great eloquence on the option of, essentially, leaving well enough alone. Reference is also made to wider opposition that was reported in what is described as “a virulent press campaign”. The organisation of the exhibition itself is seen to testify to the rapid growth of mutual support systems within the international museum community. At the same time, we can now better gauge the restoration’s artistic consequences and better appreciate why two eminent art authorities, Ségolène Bergeon Langle, the former director of conservation for the Louvre and France’s national museums, and Jean-Pierre Cuzin, resigned from the restoration’s international advisory committee.

As with the Credit Suisse sponsored exhibition “Leonardo da Vinci – Painter at the Court of Milan” which gathered £1.5bn worth of Leonardos in celebration of the National Gallery’s restored “Virgin of the Rocks” (see Figs. 17 & 18), this Ferragamo/Louvre exhibition has drawn masterpieces by Raphael, Michelangelo, Pontormo, Andrea del Sarto and others. The National Gallery (two of whose staff members served on the St. Anne restoration’s international advisory committee) loaned its hitherto unloanable Leonardo “Burlington House Cartoon” in a straight swap for the Louvre’s earlier loan of Leonardo’s original “Virgin of the Rocks” to the London Leonardo-fest. It would seem that in this international bonanza, one restored Leonardo begets another and each begets a plumply lucrative exhibition and catalogue. The current escalation in travel and restoration risks for works of art is terrifying.

The Louvre’s current exhibition is said by the curator, Vincent Delieuvin, to comprise “a science workshop”. But this “workshop” could not inform the treatment of the painting because it followed, not preceded, the restoration. Moreover, the exhibition itself imposed a guillotine on the restoration. Members of the international advisory committee who wished for more tests, for more consideration of vexing issues, felt thwarted by the Louvre’s need to finish the restoration in time for the arrival of the stupendous borrowed treasures. The cumulative assembled testimony of the exhibition’s many borrowed copies and derivatives of the “St. Anne” might well have been instructive, but, not having been seen, it finds no reflection in the restored Leonardo which artistically has pulled away from its own off-spring (see Figs. 13-16). Delieuvin’s reported twin claims that the restoration “is a true resurrection of the ‘St. Anne’” and that “The painting has recovered a depth and a relief almost like sculpture, with an intense palette of lapis lazuli blue, lacquer red, grays and vibrant browns”, seem both rather tastelessly hyperbolic and at variance with visual evidence (- see right).

Certain structural stresses in the over-heating art economy have become visible. At the exhibition’s epicentre the “Burlington House Cartoon” and the “St. Anne” (for which picture the drawing was a study), have been brought together side by side in a spectacular but counter-productive coup de théâtre (see Figs. 13 & 14). The drawn study, now discoloured but sombrely potent in a magnificently worthy black frame, conjures a breath-taking orchestration of monumentally poetic forms, forms that rightly have been seen to rival the pedimental female groupings of the Parthenon sculptures. Since the Second World War there has been no drawing in existence to rival this fragile and brittle manifestation of the grandeur of Leonardo’s thoughts. (If lost – and in recent years lorries have been burnt-out in the Channel Tunnel and a ferry and its lorry cargo was lost in the Channel – no insurance money or state indemnity could acquire another of its kind.) In contrast, the restoration-weakened “St. Anne”, with its now arbitrarily floating, obtrusively abstract and glitzy lapis lazuli blue drapery, has departed from its formerly-realised self, as the adjacent cartoon and the exhibition’s many derivative pictures mutely testify. To see strong colours subsumed within tight sculpturally integrated groups, we must now look to derivatives of Leonardo rather than to their progenitor (see Figs. 15 & 16).

As if to inoculate the exhibition viewer against this back-firing juxtaposition, the wall immediately opposite the cartoon and the “St. Anne” carries a portentous notice headed “A fundamental restoration”:

A fundamental restoration of Leonardo da Vinci’s St Anne was initially envisaged in the 1990s when a few quite conclusive cleaning tests were carried out.

The picture’s dull appearance, its hues discoloured and distorted by numerous repaintings of the sky and the Virgin Mary’s blue mantle, demanded the intervention that finally began in 2009. Minute bulges, very probably caused by the stress exerted on the picture layer by the hardening of old restoration varnishes rendered the restoration inevitable.

Preceded by an exceptional series of preliminary examinations and scientific imagery analyses carried out by the laboratories at the Centre de recherche et de restauration des musées de France (C2RMF) and generously financed by Mr Barry Lam, the restoration itself began late in 2010. The restorer, Cinzia Pasquali, was chosen following an invitation to tender and worked for more than a year at the C2RMF in the painting workshop in the Pavillon de Flore.

The restoration comprised two principle problems: the removal of the discordant repaintings, some resulting from very ancient and thick accumulations of retouches, the thinning of restoration varnishes oxidised and deteriorated by too many partial cleanings, the moving of excess varnish from one area to another using solvents, retouches and refixings down the centuries throughout its long history, the picture had obviously been devarnished and revarnished many times but fortunately the picture layer had been sufficient robust to resist this. The extremely irregular and oxidised state of the surviving varnishes distorted all the tints and, by a well-known physical effect, ‘decolourised’ and yellowed the original hues.

The gradual thinning of these varnishes to a uniform level was therefore the restoration’s major challenge. During this process, resin analyses and measurements of varnish thickness, conducted by new techniques developed at the C2RMF enabled an extremely precise approach to the thinning, which had to be undertaken delicately, both to preserve a degree of patina on the picture and protect the painting itself from any contact with the solvents used. This extremely gentle cleaning process revealed a painting in vivid colours and resuscitated the splendid lapis lazuli blues and refined violet reds and crimson kermes gum lacquer.”

In this classic museum PR conflation of aesthetic and conservation “needs”, we are variously told that aesthetic changes had been necessary on urgent conservation grounds; that the restoration was “envisaged” some time ago and that this aspiration had been reinforced by the picture itself whose dull appearance “demanded” a restoration. Meeting this demand from the inanimate is said to have been made “inevitable” by a mysterious conservation ailment in the form of “minute bulges” which “very probably” were being caused by the varnish itself.

“Very probably” is a distinctly weasel-phrase and seemed the more so because Ségolène Bergeon Langle had very recently pointed out that the minute manifestations were confined to a single board (which had been badly cut when first made) within the panel, and therefore could not have derived from overall varnishes which some were itching to remove. This analysis of the actual cause was accepted on the DVD film where it was claimed that the restoration had had to proceed because of “lifting due to contraction of the wooden panel”. That begged the larger restoration question: if the varnish was not causing the lifting, was there any conservation reason for removing it at all? A frankly negative admission on that point would, of course, have greatly strengthened the position of the “moderates” on the advisory committee who were, under any circumstances, urging restraint and caution. We now hear that not only is admitted that the liftings of paint were indeed caused by this plank, but also that they had easily been repaired locally. In hope of preventing future liftings, the panel painting is to be encased in framing that will incorporate a suitable micro-climate designed to stabilise the offending wood. On the face of it, this is good news but, in today’s museum practice, a risk removed often seems to make space for another to be incurred. And, sure enough, we also hear it is now thought that, with the provision of its own micro-climate, this great picture can be regarded as safely peripatetic – and that as such it is to be despatched in the first instance to an annexe of the Louvre at Lens, in northern France. But then where next – Tokyo? Dubai? California? At on what tariff? Perhaps in addition to adding this “restoration of the century” to our list of cleanings sold on misleading conservation-necessity prospectuses, the picture should also be put on our Now At Grave Risk of Travel Injuries category? We trust that the Louvre authorities will amend their misleading wall notice on the restoration.

The material on the picture’s surface is said to have been the accumulated product of many and various previous restorations (some with caustic substances), throughout all of which Leonardo’s original paint had suffered no injury. What chance, therefore, could the last restoration’s highly advanced, “extremely precise” techniques have produced anything other than an “extremely gentle” cleaning? Well, first of all, the proof of the pudding is in the appraising of the result – see right. Second, it is never wise to take restorers’ own prognoses at face value. Errors can occur at at any point of the restoration process. The suggestion that a uniform layer of varnish had been left in place might surprise members of the international advisory committee who had been under the impression that varying thicknesses of varnish would be left in place according to specific needs for caution (as with the especially vulnerable face of “St. Anne” – see right).

Further, questions arise in terms of conservation methodological practice. In restorations, paintings are stripped down and then reassembled by repainting. Where, then, are the detailed photographic sequences showing the painting before cleaning; after cleaning but before retouching; and, after cleaning and retouching? Without such hard visual documents the path of the restoration cannot be retraced. It was only when the National Gallery kindly provided such photographs that we were able to identify an unacknowledged change that had been made to the angel’s mouth in the London “Virgin of the Rocks” (see comments at Figs. 17 & 18).

In the two versions of the Louvre exhibition catalogue (one of 52 pages at 8 Euros and one of 448 pages at 45 Euros) there are not even any facing images showing the picture before and after restoration. Such a pairing is found in the (excellent) Beaux Arts special “Léonard de Vinci – Les secrets d’un génie” at 6.90 Euros (a similar comparison is shown here in Figs. 14 & 16). There is also a helpful before and after restoration record of the National Gallery’s “Virgin of the Rocks” (see Figs. 17 & 18).

The Louvre and the National Gallery leonardo restorations share a common methodological feature: in both cases it is said that old varnishes were thinned but not completely removed. This claim creates a conundrum because in both cases changes have taken place which seem inexplicable in terms of a mere thinning of varnish. When explanations are sought or when appraisals are attempted, restoration authorities sometimes take fright, retreating behind claims that theirs is a highly specialised technical field whose mysteries are simply unfathomable to outsiders. Restorers themselves often don the proverbial doctors’ white coat and claim to have acted on not aesthetic grounds at all but on (quasi-) medical ones. For the “St. Anne” restorer, Cinzia Pasquali, this restoration was not made for aesthetic reasons. Instead: “This was about caring for a sick patient. From the conservation point of view we had to intervene, primarily to address a cracking of the varnish that could leave the paint exposed to damage.” Well, we now know that in this particular case the patient was not as sick as had been thought. But more importantly, we should remember at all times that works of art are made by people to be looked at by people. They are not created as laboratory specimens. Artists work with materials so as to produce values and relationships between values. No scientific test can analyse a value, let alone an inter-related group of values. To its maker, the professional test of a work of art is how it looks – the painter stops working precisely when the picture looks right.

In the realm of art and away from corporately funded museum politics, the ultimate test of a restoration is also how it looks – but that is to say, not how it strikes the passing viewer (who may or may not be thrilled by solvent-brightened colours) but how it looks now as compared with how it looked previously; how it looked not just immediately prior to restoration but in its successively recorded history; and, most especially, how it looked the last time it was cleaned. If picture cleanings did no harm, if they were as simple and non-destructive as cleaning a window, each restored work would return to its appearance when last cleaned, and there would be no surprises, “discoveries”, “revelations” – or controversies. While no one ever berates a window cleaner for ruining the views, restorations irreversibly change a picture’s “view” on to the world. Restoration is a one-way street that runs away from history, away from the original work.

All cleaning controversies turn on the extent to which pictures suffer during restoration. Even among those who authorise restorations, some concede that there are losses as well as gains and frankly admit to seeking the best trade-off between improved legibility and pictorial injury. Defensive restorers insist that pictures cannot be harmed by their own “advanced”, “gentle” and “scientifically underpinned” methods. Making a fetish of the “safety” and the “science” of restoration methods attempts to shelve restorers responsibility to identify and account for all material and aesthetic changes. Given that all restorers’ methods cannot be superior, none should be held beyond question. With the physical alteration of art, aesthetic appraisal is essential to scholarship and art’s protection. In appraising restorations, the comparison of like with like is of the essence.

In visual arts, appraisals are necessarily made by visual comparisons. Pictures are made by eye, hand and mind, to view by eye and mind. Because each cleaning destroys the earlier state, comparisons can only be made between pre and post-restoration photographs. While straightforward cleaning might always be expected to achieve a greater vivacity of pictorial effect, it should never be made at the expense of the pictorial relationships, patterns, or gradations made in the service of modelling, that can be seen to reside in the uncleaned work. If the relationships can be seen it is because they are there – whatever chemical analyses might suggest to the contrary. The aesthetic production of pictorial values by artists is the proper science of art. Unfortunately, in such terms, the values that were formerly evident in this great picture seem not to have fared well in this last cleaning.

Above, Fig. 1: Leonardo da Vinci, “Virgin and Child with St. Anne”, detail, before cleaning. Note the artist’s very selective and artfully focussed disposition of his brightest lights, and, at the same time, the extremely subtle but sculpturally effective modelling of the Child’s right shoulder and arm. Note too, the careful placement of tonal values throughout this grouping and how successfully these values contribute to a general sense of sculptural placement in space – for example, how the Child’s left forearm recedes behind the bright wooly top of the lamb’s head, and how appreciably it recedes from the Child’s nearer right arm.
Above, Fig. 2: Leonardo da Vinci, “Virgin and Child with St. Anne”, detail, after cleaning.
How to explain the differences between these two greyscale versions above, of Figs. 3 and 4 below? It has been said that the restorer left a thin layer of varnish over the paint throughout the picture. It is hard, on the face of it and given the scale and nature of the changes that took place in this single restoration, to see how they might have resulted from a reduction rather than an elimination of the varnish (but see below). And it is hard, too, to see how a restorer, cleaning freely by hand with nothing more precise than a cotton wool swab (evidently dragged not rolled in this instance) might differentiate perfectly between the lowest level of a varnish and the upper level of an old glaze of similar colour and tonality at every point. When previous restorers had applied their varnishes, often, presumably, after harsh cleanings, would those then-new, solvent-saturated varnishes not have integrated themselves to any degree within whatever material was to hand?
One question that might always be borne in mind when evaluating pre and post-cleaning states, is whether or not the cleaned (altered) state looks more or less characteristic of the artist’s known traits. (This might be held a perilously subjective notion to conservators of a certain “scientific” bent, but without such an artistic navigational system, how might any restorer proceed?)
Does this after-treatment Fig. 2 detail look more Leonardesque than the before treatment detail at Fig. 1? It is hard to see how this question could be answered in the affirmative. The melting of the Child’s limbs into and out of the artist’s light in Fig. 1 seems quintessentially Leonardesque, while the after-cleaning state of Fig. 2 might be thought rather more Michelangesque by comparison. A key difference between these two great Renaissance figures (and sometime rivals) was that Michelangelo was not averse to autonomously forceful contours. Leonardo, of course, wished to out-sculpt the great sculptor with shaded simulations of form on the picture plane; with forms disposed within an envelope of space and light that was entirely of his own shaping and in no way dependent on the contingencies of the real world in which sculptors’ productions must always take their chances. The existence of the surface upon which paint was applied was a fact to be denied or concealed by the sheer force of artistry. One consequence of this cleaning is that the painting’s picture surface comes further to the fore. The restorer, Cinzia Pasquali, attributes this to the fact that although the work was known to be unfinished, “now we can actually see it”, as if that might be considered some kind of gain, but anything that causes the picture surface to compete for attention with the intended illusion upon it can hardly be thought characteristic of Leonardo’s wishes or intentions, and anything that causes a picture to seem unfinished and less resolved than previously was the case, might more realistically be taken as an aesthetic alarm call than as a vindication of raw method.
Above, Fig. 3: Leonardo da Vinci, “Virgin and Child with St. Anne”, detail, before cleaning.
Work on this section of the painting produced one of the strongest and most keenly contested controversies within the international advisory committee. A “varnish” on the Child’s body was taken by the restorer (and others) to be an earlier restorer’s decayed varnish. This reading was challenged by the student of Leonardo’s painting technique, Jacques Franck, who noted that this material had contributed to the modelling of the Child to a substantial degree and in a manner that went beyond any straightforward varnish layer. He felt, therefore, that it should be preserved until no doubt existed about its precise function and date of making. He and others of this opinion called for the disputed coating to be revived rather than removed, but they were over-ruled on the committee. Analytical tests were made on the material and these were said to have proved on chemical grounds that the material taken to be constructive orginal glazing by Leonardo was in fact only a later varnish. But if this chemical analysis is held to have provided an indisputable basis for excluding the possibility that the material was original, then it is incumbent upon those who removed it to explain how the various apparently artistic effects that it had contributed, had been achieved. In a nutshell the problem is: How might an overall “varnish” as opposed to a glazed layer, contribute differently in local areas that happen to coincide with discrete parts within an artist’s design? In effect, this is the same challenge that we mounted over two decades ago to the restorers at the Sistine Chapel who held that sculpturally-enhancing shadows on Michelangelo’s frescoes were the happy consequence of soot from candle smoke that had accumulated on the ceiling over many centuries.
Above, Fig. 4: Leonardo da Vinci, “Virgin and Child with St. Anne”, detail, after cleaning. Visually, it would seem clear that the ground around the lamb’s tail has been in effect “scoured”; that darkened passages which threw the lamb into relief and prominence have been in effect “abraded”. Is it possible that a mere thinning of an overall varnish could have been responsible for such a transition?
Above, Fig. 5: Leonardo da Vinci, “Virgin and Child with St. Anne”, detail (St. Anne), before cleaning.
Above, Fig. 6: Leonardo da Vinci, “Virgin and Child with St. Anne”, detail (St. Anne), after cleaning. The changes in this face can only thought alarming and deleterious. Vincent Delieuvin’s claim that cleaning has enhanced the sculptural effects of the picture seems plain wrong. For any draughtsman or sculptor, the image at Fig. 5 would have to be considered to hold more “information” than that at Fig. 6. The shadows contribute to a far greater sense of sculptural relief and surface relationships. One might say that the cleaned state now appears to be modelled in shallower relief than that found before treatment. Before the cleaning, the plaited braid of hair running over the top of the head, partook of a general system of shading. After cleaning it has emerged generally lighter and, on the viewer’s left side, no longer tucks into the general ensemble that comprises the more shaded side of the head. Moreover, of the shading on the face, it can immediately be noted that a certain transparency has been introduced – it is now possible to see under St. Anne’s (true) right eye, an earlier positioning of the iris by Leonardo. It is a commonly encountered consequence of picture cleanings that they take works further towards the condition of transparency that is seen in infra-red photographs, where the light penetrates the surface of the paint. While that kind of “imaging” is very useful in terms of identifying earlier stages in a work’s genesis and, specifically, in identifying an artist’s own under-drawing, it cannot be a good thing for works of art themselves to be rendered transparent.
Above, Fig. 7: Leonardo da Vinci, “Virgin and Child with St. Anne”, detail (St. Anne), before cleaning.
Above, Fig. 8: Leonardo da Vinci, “Virgin and Child with St. Anne”, detail (St. Anne), after cleaning. This issue and the artistic dangers of increased transparency had been raised on the international advisory committee by Jacques Franck who had urged that a sufficiency of varnish be left on the face of St. Anne to prevent the inevitable consequence of age-induced transparency in Leonardo’s paintwork from emerging. He has described the peculiarly heightened dangers that were to be expected because of Leonardo’s method on flesh passages at that late stage in his career (when the “Mona lisa” was being produced). He paraphrases his submissions to the committee on the constructive use of “velatura” in the St. Anne head in the following terms:
In Leonardo’s time, those ‘velature’ were meant to interplay optically with the undermodelling and a more roughly worked state of the image. It resulted in opalescent flesh tones linked to the shadows very gradually, thus producing the typical smoky effect called “sfumato” in these sections. The ageing of the binding agent through time has made the opalescent micro-layers become increasingly transparent: details like the eyebrows, some sharp accents in the mouth, in the nose’s end seem to have been executed in the final state of the Saint’s head but have not. They are parts of the underdrawing that are emerging in the visible light due to increased transparency now.
The same with the undermodelling. To date, the soft transitions having lessened markedly, the contrasts between light and shade are much stronger, inevitably so. More microns of old brown varnish left [in place] would have compensated for the now missing opalescent subtleties of Leonardo’s “sfumato”. Hence the difference to be observed between before and after cleaning.
The Louvre was advised by me not to thin too much for that very reason. Leonardo’s subtleties need a substantial ‘veil’ of old varnish left over them, a situation clearly respected by Alfio del Serra in cleaning [Leonardo's] Annunciation in the Uffizi, for the picture’s atmospheric effect is beautifully preserved.”
Above, Fig. 9: Leonardo da Vinci, “Virgin and Child with St. Anne”, detail (St. Anne), before cleaning.
Above, Fig. 10: Leonardo da Vinci, “Virgin and Child with St. Anne”, detail (St. Anne), after cleaning. One sees in this comparison of the eyes, not only the emerged iris but also a substantial degree of lost shading around the eyes. This is very commonly encountered in restored faces. The eye is best understood anatomically as a ball set in a hollow (a hollow that is formed by the brow/nose/cheekbone configuration), and its surface is only made visible through lids that close for protection and during sleep. The “eye” that is defined by the aperture of the opened lids is properly to be understood as a part of the surface of the larger eyeball. The relationships between these component parts are very distinctive to individual heads (or to the idealised “types” of heads devised by artists). Anything that reduces the original artist’s construction of those relationships (made by shading essentially) is extremely harmful to the “plastic” properties of the head as well as to its characteristic expression. A commonly encountered feature of restored faces is that the shading around the eye, which “sets” it in its protective zone, is so diminished that the more precisely delineated parts – the shapes of the eyelid apertures and the iris/pupil – of the eye become more apparent, become over emphatically drawn.
With regard to the level of cleaning that is said to occurred on the St. Anne, Franck had been assured that varnish would be left in place to a thickness of 18 to 20 microns. A micron is only one-thousandth of a millimetre or 0.001 mm. It might be wondered how a restorer working with solvent-laden cotton wool swabs (as seen in use on the DVD film, for example) might ever be able reliably and predictably to operate evenly to such ultra-fine tolerances. In the event, Franck was told that on the St. Anne the level of varnish that had been retained was of only 12 – not 18 to 20 – microns depth, or in other words of 0.012mm. This raises the question: Was this, as had been promised, the area of greatest varnish thickness that was left in place, or was this, in fact, the “uniform level” to which the painting had been cleaned throughout, as is described in the exhibition on the wall notice?
Above, Fig. 11: Leonardo da Vinci, “Virgin and Child with St. Anne”, detail (St. Anne), before cleaning.
Above, Fig. 12: Leonardo da Vinci, “Virgin and Child with St. Anne”, detail (St. Anne), after cleaning. It would seem inconceivable, to any sculptor’s trained-eye that this section of the face, after cleaning, might be considered to enjoy enhanced sculptural values. In purely formal terms, what is seen here is an advance and an expansion of the lights at the expense of the darks – which darks had comprised in this working method the “constructive” component of Leonardo’s “modelling” on the light ground of his picture. The lights had not been painted as values, they were merely the sections of ground left unmodified by Leonardo’s meltingly applied shadows.

As with the Louvre’s St. Anne, the varnish (which had been described as having come to constitute a threat to, as well as a disfigurement of, the paint) was said to have been thinned not removed. Indeed, when shown the painting part-cleaned, and when it was lit with an ultra-violet lamp, remains of (patchy) varnish were to be seen on the picture. Against that evidence, we face the problem of how the changes that manifestly occurred (as seen above) could have arisen. For example, how was the angel’s mouth changed if it remained under a film of varnish? What accounts for the fact that after the last cleaning the picture did not return to anything like its condition when previously cleaned sixty years before? Specifically, what accounts for the great lightening of the sky seen in the top right, as opposed to the sky seen on the left? What accounts for the great change in the Virgin’s blue robes?

Shedding archival records at the Tate and the Victoria and Albert Museum

A disturbing account in the Guardian of abuses of archival records within the museum world (“Tate’s national photographic archive ‘rescued from a skip’ after internal tipoff”, 24 February 2012 ) disclosed how the Paul Mellon Centre for Studies in British Art, received a call from a Tate employee who said “you might like the curatorial photo archive because we’re about to throw it on to a skip” (- or, in American usage, throw it into a dumpster). Shocking as this report was, it came as no surprise to us because in recent years the Tate has shown a notoriously cavalier way with its artistic holdings and its archival material (see right). More surprising was the Guardian’s revelation that an archive of black and white photographs of almost every item held at the Victoria and Albert Museum and grouped by subject, had also been dumped by the curator in charge.

This dual elimination of black and white photographs echoes the destruction of old black and white television programmes that routinely took place at the BBC until 1978. A further destruction of archival property within British cultural bodies in recent years included that of newspaper collections held by the British Library. Sometimes a justification offered for archival vandalism is that essential “content” has been preserved by transfer to other media. The speciousness of such claims and the frequent destructiveness of such practices were searingly established in Nicholson Baker’s 2001 book “Double Fold: Libraries and the Assault on Paper”.

Following our reported comments in the Guardian article, we received a note of sympathy and an invitation to read the “Florence Declaration” from the director of the Photographic Library of the Kunsthistorisches Institut Florenz (the Max-Plank Institut), Costanza Caraffa. We are indebted: it seems that there is a wider threat to photo archives. The Florence Declaration is a call for the integration within photo archives and libraries of photographs in both analogue format and digital format. Their dual preservation is rightly taken as being essential to preserve the photographic heritage for future studies.

The Florence institute’s own photo library was founded in 1897 and today comprises more than 600,000 photographs of Italian art from late antiquity to the modern era. Like many photo libraries, the institute has recently engaged in transferring photographic images to the new digital media to aid electronic cataloguing and greater accessibility. There can be no quarrel with such exercises, but, paradoxically, by virtue of the editorial decisions that are inherent in any major transfer of material to new systems of storage and dissemination, the Institute has become the more conscious of the unique and irreplaceable nature of its general physical historic compilation; of the value of its illuminating bequeathed collections-within-the-collection; and, of the unique testimonial potency of its individual “hard copy” historic photographs. (Needless to say, this combination of visual acuity and heightened sense of patrimonial responsibility is one with which ArtWatch is in great sympathy.)

For our own rather specialised primary purposes the value of photographs lies not so much in their individual intrinsic qualities, as in their relationships to other, earlier or later photographs. The accumulated sequences of images (of paintings, drawings, prints, architecture, sculpture, metalwork, illuminated manuscripts, stained glass, wall paintings and textiles) held in the Courtauld Institute’s Witt and Conway photo libraries, and the photographs of paintings held in the National Gallery’s curatorial and conservation dossiers, greatly facilitate the identification and demonstration of injuries to works of art through restoration “treatments” (see right, Fig. 4).

The great value of photographic collections is, however, multifarious not singular. For some researchers, the self-same images might assist in making specific attributions of authorship, or in establishing chronological relationships within an oeuvre or period. For others still, the images can inform more general scholarly, thematic, historical, artistic or even sociological studies. In truth, all such focussed collections facilitate and trigger infinite lines of inquiry and speculation – and their benefits can neither be quantified nor anticipated in advance. Digitalised versions of photo collections – immensely useful as they are – cannot replicate or replace the ultimate benefits of “hands-on” studies of hard copy photographs, each of which is a physically and historically unique record made at a certain time, in a particular way, of a certain object, under a particular lighting condition. The ability to compare, juxtapose and read such various, culturally-expressive living historical records, in real space and real light, one against another, freely and without the physical and visual fatigue that attends a prolonged relationship with a fixed electronic screen (see right), is a methodological luxury and necessity. A photograph is a thing; a digital version is a virtual simulacrum of a thing. Although it is technically possible to track every manipulation of a digital photograph’s raw data, in practice, a photograph-as-object is more trustworthy, carries its traits and its history about its person, as it were. A most moving evocation of the multiplicity of uses within hard-copy photo collections – and of their great vulnerability in a philistine, cost-cutting world – was brilliantly captured by Stephen Poliakoff in his 1999 award-winning television drama, “Shooting the Past”.

We have long suspected that the inescapably destructive impulse of restorers constantly to undo and redo the material fabric and the artistic character of works of art through restoration/conservation “treatments” is a manifestation of a wider, history-hating cultural pathology; a narcissistic and hubristic desire of succeeding generations to remake history in their own image rather than to learn from it. The evidently assumed similar right of curators to undo and discard the historic record itself – even when held it is held in public trust by supposedly dedicated, culturally and fiscally privileged institutions like the Tate and the Victorian and Albert Museum – and even though that record possesses the power to hold to account as well as to illuminate, is a dangerous new, hitherto unimaginable, cultural low.

Above, Fig. 1: The ArtWatch UK Journal showing the demeaning treatment of the Tate’s Rodin marble sculpture, The Kiss, which had been bought for the Nation by public subscription. The strings had been added by the “conceptual” artist Cornelia Parker. Parker was paid £50,000 by the Victoria and Albert Museum for a work that consisted of crushed musical instruments. The work was exhibited at the V&A. Parker said of it that “A vibrant working class tradition has been brought into the British Galleries [of the V&A] in the guise of a heraldic ceiling rose. I wanted to create something that would explore the ideas of duality: light/dark, silence/noise, upper class/lower class, the North/South divide, black cloud/silver lining, death/resurrection. I see the work as a ghostly last gasp of the British Empire.” She denied that by crushing a band-full of brass instruments she was denying working class children the opportunity to play them. An artist who was affronted by Parker’s purloining of the Rodin, liberated the sculpture by cutting off the strings. He was arrested on a charge of “suspicion of causing criminal damage.
A curator at the Tate (where Parker had been a Turner Prize nominee) said of her stringed additions to the Rodin, she had created a work that is: “suggestive of the constrictions of relationships, the caughtupness and complications… [the] desire to drag new life out of dead things.”
Above, Fig. 2: The Tate’s director since 1988, Sir Nicholas Serota, as shown in the Jackdaw No 5, February 2001 (“Serota Dangerous Dictator?”), when he had been in place for thirteen years. When Cornelia Parker asked to use lining canvases removed from Turner paintings at the Tate for an exhibition of her own work, conservators at the gallery protested against the misuse of technical archival material. They were over-ruled by Serota. When a small municipal German gallery that shared premises with a music college and had no perimeter defences, requested the loan of two important Turner paintings, Serota agreed to lend, instructing the German gallery to collect the paintings from the airport as they would not be being courrier-ed by the Tate. When the paintings were susequently stolen by Serbian gangsters, the Tate paid a £3.1m ransom. It could easily afford to do so because, earlier, with the intervention of a Government Treasury minister, the Paymaster General, Sir Geoffrey Robinson, the Tate had shaken a £22m windfall out of the insurance underwriters of the stolen Turners. The money had been urgently needed, Robinson said, to complete Tate Modern.
Serota is reported in the March 2012 The Art Newspaper to have defended the decision to shed two highly respected curators who are specialists in British art of the 16th-19th centuries. This is not a cost-cutting exercise, a Tate spokeswoman has said, but an attempt to bring new blood and younger curators into the Gallery. Even though the modern collection was moved out of the Tate Gallery on the completion of Tate Modern, the entire pre-19th century part of the British collection remains effectively confined to a single room.

Because the pronounced and various changes of value that can be seen within the two photographs cannot be accounted for in terms of differences of photography and processing, it must be concluded that they arise from the intervening restoration.

The Perpetual Restoration of Leonardo’s ‘Last Supper’ – Part 1: The Law of Diminishing Returns

The restoration of Leonardo’s “Last Supper” (1977 -1999) was defended last month at the National Gallery symposium on the artist’s methods and influence, by Pietro Marani, the Leonardo scholar who co-directed the restoration from 1993 onwards. When we pointed out that while the previous restoration had been praised for recovering all of Leonardo’s authentic paintwork, the last restoration had in fact introduced vast areas of new painting, Marani held that restorers and curators may impose their own generation’s values and interpretations. Appeals to the authority of one generation cuts little ice given how happy each proves to be to undo and redo its predecessor’s work – and, besides, given that on past form we are already half way along to the next generation’s “Last Supper” restoration, the one presently being defended is already approaching its own “sell-by date”.

In its early days, the last restoration was presented as a near miraculous liberation of the original and entirely unadulterated handiwork of Leonardo da Vinci, when that claim, far from being a novel one of its day, was, as mentioned, a re-run. In 1958, John Canaday, the art editor and art critic of the New York Times, reported how, following the war-time bombing of the refectory housing the mural in Milan:

When the sandbags were removed…the ‘Last Supper’ was in such pitiful condition that historians were ready to list it as a war casualty. But since then the picture has been gone over as definitively as the combination of exhaustive scholarship and high technical skill make it possible to preserve once and for all whatever is discoverable of the original work. The results are better than anyone expected, although the painting still suggests a ghost at best or, at worst, an embalmed relic…”

Taking their cues from restorers, commentators often dismiss past treatments and celebrate more recent scientifically under-pinned “definitive”, “once and for all” and “miraculous” ones. (Just this week, a Rubens – his “Cain Slaying Abel” – that has been restored at the Courtauld Gallery with funding by the Bank of America, is said in a press release to have stabilized the painting for nothing less than “the next one hundred years”.) The “Last Supper” rescue operation took place in two stages in 1947-49 and 1952-54. In the first, the restorer Mauro Pelliccioli (see Fig. 1) supervised by a former Superintendent of Fine Arts in Milan, Fernanda Wittgens, anchored the disintegrating paint with shellac. As Wittgens’ wrote in the Christmas 1954 issue of Art News, “This was not ordinary shellac, of course, but an absolutely colourless one recently produced in England by a chemical process that removes all wax.” With this shellac, Wittgens went on, Pelliccioli performed his wonders:

…it produced the greatest miracle of the entire restoration. The reattachment of the painted surface was achieved to perfection, and the colours acquired a new consistency as though they had been actually rejuvenated by the shellac that made them adhere to the wall…Mauro Pelliccioli, by doing away with all glues soluble in water, had permanently eliminated the danger of mould: he had at last hit upon a tremendously strong, transparent adhesive impervious to humidity.”

When the shellac was settled, Pelliccioli began scraping off the repaints of earlier restorers. Bernard Berenson visited the scaffold and later reported how, with no more than a penknife, a razor and a drop of turpentine, Pelliccioli had “touched bottom” by removing the “multiple restorations of centuries” and allowing the paint of Leonardo, “deteriorated by the centuries but no longer deturpated by incompetent hands” to be seen once more. In his diary note on October 21st 1953 Berenson said that Pellicciolli had known precisely “where to scrape” – a point echoed and amplified in H. H. Pars’ 1957 “Pictures in Peril”:

Pelliccioli was able to distinguish those parts of the painting where nothing of the original painting was left, and those parts where overpainting and restoration concealed Leonardo’s own brilliant colours. Step by step these were revealed in the now firmly-fixed painting until we are now able to see Leonardo’s ‘Last Supper’ in better preservation than for many generations, deteriorated through the centuries it is true, but no longer marked and deformed by incompetent hands.

Thus, to everyone’s satisfaction, the work had been physically rescued and what authentic Leonardo paintwork could be exposed to view had been liberated. Earlier restorers’ repainting was left in place only where it covered bare wall. Just twenty-one years later in 1975, Pinin Brambilla Barcilon, a former student of Pelliccioli’s, reported that fragments of paint were falling off the mural. Two years later, following tests, she began re-securing those parts of the paintwork that were becoming detached. Her minimal and straightforwardly necessary conservation measure was to mushroom, in parallel with the restorations of Michelangelo’s Sistine Chapel ceiling frescoes, which began in 1980, and Masaccio’s Brancacci Chapel frescoes, which began in 1981, into one the most protracted radically ambitious, corporately-funded and controversial restorations of modern times.

It can now be seen that 1977 marked the high water mark of confidence in the recuperative powers of restorers and in the legitimacy of their increasingly bold and experimental methods. In the previous decade, heroic actions in wake of the floods in Florence had carried restorers to unprecedentedly high levels of public respect (even when they opted to strip frescoes from walls). In Britain, following a spuriously engineered triumph with the restoration of Titian’s “Bacchus and Ariadne” at the National Gallery, criticism had been declared dead by the victors. The National Gallery launched its Technical Bulletin in 1977 and in it, the Gallery’s head of conservation science, Joyce Plesters, mused complacently: “one or two readers may recall the furore when the cleaning of discoloured varnishes from paintings…began to find critics”. In the same year, Kenneth (Lord) Clark published his two volumes memoir “Another Part of the Wood” and “The Other Half” in which he pronounced picture cleaning “a battle won” and claimed credit for having taken the first steps, as director of the National Gallery (1934-1945), by installing a “scientific department with all the latest apparatus”. He had done so not because he believed in the “application of science to the problems of cleaning”, but because “until quite recently the cleaning of pictures used to arouse extraordinary public indignation and it was therefore advisable to have in the background what purported to be scientific evidence to ‘prove’ that every precaution had been taken.”

Duping the public in such manner occurred in Italy. In 1981, a year after the start of the Sistine Chapel ceiling restoration in Rome, the restoration of the Brancacci Chapel commenced. Speaking of the prior tests made in connection with that restoration, the author Ken Shulman cites an Italian art historian (“Anatomy of a Restoration”, p. 156), who had said:

Let’s be honest and admit what all restoration directors will say in private. At the beginning of any restoration, you order as many tests as you can imagine, fully aware that only about five per cent of them will be of any use during the restoration. The rest of the analyses are merely window dressing.”

With Leonardo’s “Last Supper”, amidst all the preliminary testing, no-one seemed concerned by the fly that was present in the ointment of Pelliccioli’s celebrated reductive, purist restoration: his liberation of Leonardo’s paintwork had come at a cost in terms of artistic legibility. A law of diminishing returns had been set in motion that would (as we will see in Part 2) produce panic and confusion among the restorers and their supervisors.

What Price a Smile? The Louvre Leonardo Mouths that are Now at Risk

There is an air of confusion, and even a whiff of crisis, in today’s international art restoration community. At the National Gallery’s CHARISMA symposium on Leonardo’s technical practices and influence (January 13-14), many fascinating and highly informative demonstrations were made of non-invasive imaging techniques. A ground-breaking paper by Ana González Mozo revealed how the Prado’s copy of the Mona Lisa had faithfully tracked Leonardo’s own revisions on the original work. Imagine – a copy not so much of the finished masterpiece but of its very genesis. The proceedings, happily, are to be published. Unfortunately, at this richly rewarding and even-handedly conducted event, two critically serious weaknesses emerged during the proceedings and discussions that seemed linked and together to constitute a wider international art conservation faultline.

That is, firstly, there are manifest deficiencies of understanding on the crucial relationship between the discoveries that are being made through advances of technical analysis, and the original painterly/artistic means by which the art-objects-under-investigation were produced by artists in the first place. This single shortcoming carries profound cultural and professional consequences and is, we believe, a root cause of many of the controversies which arise in the field. Secondly, and concerning these controversies, a number of speakers (particularly Italian speakers, as it happens) used their papers to dismiss critics of their (sometimes long-past) restorations. Such combative unrepentance suggests how hard the task remains to establish some proper and effective systems and habits of disinterested critical appraisal in what is becoming an alarmingly expanionist and self-authorising and validating field. Much might be gained if restorer/conservationists themselves would devote more energies to those fruitful knowledge-advancing studies that leave vulnerable and uniquely precious historical works of art intact and free from what too often seem injudicious or debilitating interventions.

For some speakers, “virtual” indications of changes within pictures, seemed to be taken in themselves as invitations to swabs-on interventions. Certainly it seemed tactless and provocative when, at a time of great disputation, a Louvre curator, Vincent Delieuvin, ended a talk on non-invasive examinations of the museum’s Leonardo “Virgin of the Rocks” with the bald declaration “Restoration of the painting is possible”. Possible? No doubt it is politically so today at the Louvre, but desirable even under the present controversial circumstances? And what exactly has made this hitherto untreatable picture (see caption at Figs. 2 and 3) treatable? Must every restored masterpiece immediately trigger another? Will curators and their restorers never allow decent intervals for the fumes to evaporate and for their handiwork to be evaluated with due attention and consideration after the inevitable PR media barrages that nowadays accompany all major restorations? For that matter, is no one in authority concerned by the general and wider risks that are being incurred in the current Leonardo binge in which the oeuvre itself is being speculatively “grown” even as its most secure works are being recast by today’s more adventurous generation of technicians?

Concerning the Louvre fracas, Didier Rykner, surprised and disappointed us in his Art Tribune post of January 7th by disparaging the international debate on the restoration of Leonardo’s “The Virgin and Child with Saint Anne”, that followed a Guardian report. Headed “A follow-up to the Debate…” that somewhat churlish post afforded a proxy defence of the Louvre’s current policy. Of the momentous resignations of Sègoléne Bergeon Langle, the former director for conservation at the Louvre and France’s national museums, and Jean-Pierre Cuzin, a former director of paintings at the Louvre, from the Louvre’s own international advisory committee, Rykner complains that the restoration has sparked a debate “when in fact nothing new has happened since since the month of October (see our article in French).” One thing that is new is that everyone now knows (thanks to the diligence and reach of the international press) what very few previously appreciated: a profound schism exists over picture restoration methods at one of the world’s greatest museums – in truth, the world’s greatest single museum – and, that the restoration of a major work of the world’s most famous artist is the centre of that dispute.

Rykner characterised the “Virgin and Child with St Anne” restoration as one in which only “three points had to be solved”, when, far from being some problem-solving exercise, this is a debate about the very nature and legitimacy of actions that might be made on an immensely complex, unfinished, ancient and precious masterpiece. Restorations never take place in antiseptic clinical spaces. They always reflect philosophies, interests and professional inclinations or dis-inclinations towards radical interventions. Conflicts in this arena are far from trivial and it is desirable that they should not take place in the dark.

There is great irony in the present situation. For many years after the Second World War, the Louvre occupied the virtuous conceptually elegant and restrained end of the restoration spectrum. And it did so in explicit opposition to the brutal simplistic campaign of “total cleaning” launched at the National Gallery by the restorer Helmut Ruhemann, who insisted that “important paintings should be thoroughly cleaned before we theorise about them”. Ruhemann’s influence at the National Gallery was under-written by the long-serving post-war director Philip Hendy, who wrote in the catalogue to the didactic 1947 exhibition of pictures cleaned (in secret) during the war: “The purpose of this exhibition is not only to do justice to the cleaned pictures, but, by extending the knowledge of their condition, to bring about a higher standard of criticism in this all-important subject.” By 1958 Bernard Berenson had been persuaded that “the recent restorations of pictures in the National Gallery are defended by most English people against the almost universal disapproval of continental craftsmen and critics.”

Berenson was right about the continental opposition but, perhaps being overly-reliant on the reports of Kenneth Clark (who had launched the National Gallery’s cleaning blitzkrieg in the late 1930s when he had hired “the brilliant Ruhemann”), he had quite missed the scale and the ferocity of opposition within England. In 1947 Hendy had made the self-defeating claim that: “There would not in all probability have been so much criticism of the appearance of the pictures cleaned since the war began if the public had been kept waiting until the cleaned pictures could be shown as they are shown [all together] now. Instead, they had to be scattered among the dirty pictures upon walls which there had been neither time no labour even to brush down after six years of increasing exposure to the elements.” If Hendy could not see the force of a widespread preference for “dirty” over “cleaned” pictures, by 1977 his predessor director, Kenneth Clark had quite forgotten the controversy the returned pictures had provoked: “A cleaned picture often looks very bright when first it is finished, but it loses its shine after a year or two, and I was fortunate in that the pictures I brought back for the reopening of the Gallery, all of which had been cleaned, had had time to ‘settle down’. No one complained about them.”

For a concrete example of the war-time consequences of Ruhemann-esque preludes to theorising, see Figs. 9 and 10. For a discussion of the role of the German restorer, Johan Hell, whose highly restrained work in Britain earned much support among artists and private patrons, see this author in the June, July/August and September 2006 issues of the Jackdaw. Hell’s great influence in Britain (he restored the collection of the Dulwich Picture Gallery to acclaim) was carried to the United States, albeit in dilute form, by his sometime student, John Brealey. In 1951, René Huyghe, the Louvre’s chief curator of paintings and drawings advised restorers and curators “If there is the slightest doubt, stop; for in this matter it is inadmissible to make a mistake. Excessive prudence leaves the future open without compromising it. But mistakes made by presumption are irreparable.” In the Sunday Times (15 January 2012) Bergeon Langle said “We prefer the most moderate cleaning possible. But my views weren’t taken into consideration.”

Not heeded, perhaps, but widely noted nonetheless. The debate that has been opened by the two Louvre resignations shows no sign of abating. In a recent article Bergeon Langle has further explained: “I deemed that the restoration was not being carried out in line with what I imagined was necessary for this Louvre painting. That is my firm belief.” We now learn through such increasingly frequent press reports and the assorted leaks and briefings on this schismatic dispute within the museum’s twenty members strong advisory committee, that the Louvre’s present curators, with the encouragement of certain English and Italian curator and conservator members of that committee, are resolved to pursue more radical, less precautionary treatments. What makes this dispute-among-experts so alarming is that evidence of the consequences of the shift from caution and physical restraint within the Louvre already exists – we don’t have to read the book (and the official accounts, should they ever be made available), we can simply look at the pictures: as previously shown, restorers at the museum may now change and then re-change the expressions on old master faces without even being required to record their adulterations in the museum’s dossiers. This, by any standards is an already extraordinary and indefensible position.

News of the Louvre resignations comes just seven months after the shocking disclosure of its cosmetic facial exercises and at the point where the cleaning of the “St. Anne” is completed and the perilous stage of retouching begins. It so happens that the expression of St. Anne’s mouth is interrupted by a panel join (see Fig. 1) which might provide another temptation for a little cosmetic surgery with the retouching brushes. We were not reassured when the Louvre’s present head of painting, Vincent Pomarede said recently that the retouchings would be “reversible”. “So what?”, we would ask. As shown right (Fig. 5), the Louvre recently made two egregious errors on a single Veronese face. That the second falsification – which is still in place – is theoretically as removable as the one it superseded does not mitigate the presently persisting offence and lapse of curatorial vigilance. The two members of the Louvre advisory committee from the National Gallery who have been enthusiastic supporters of the current restoration (the then curator Luke Syson, who has moved to the Metropolitan Museum, New York, and the head of conservation, Larry Keith), happen themselves to have been responsible on their own patch for another incomprehensible, initially unacknowledged (- even in the Gallery’s own Technical Bulletin report) but again “reversible” alteration to a (Leonardo) mouth – see Figs. 6, 7 and 8.

One of the more monumentally controversial restorations defended at the National Gallery symposium was that of Leonardo’s “Last Supper” by Pinin Brambilla Barcilon. Sponsored by the Olivetti corporation, the restoration had been directed by the distinguished Leonardo scholar Pietro Marani, who is a member of the Louvre’s “St. Anne” advisory committee, and like Syson and Keith an enthusiastic supporter of the present restoration. When we pointed out at the conference that the previous restoration of the “Last Supper” in the 1950s had been praised at the time by Bernard Berenson as an ultimate recovery of all the surviving authentic Leonardo paintwork, Pietro Marani countered by claiming a right for each generation’s restorers and curators to impose their own values and interpretations on historic works of art. The consequences for Leonardo’s “Last Supper” of the claimed (“Buggins’ Turn”?) right to undo and redo every great work of art, will be examined in our next post.

Above, Fig. 1: St. Anne, detail from Leonardo’s “Virgin and Child with St. Anne”. The vertical line that runs through the right-hand end of the mouth marks a split in the panel.
Above, Fig. 2: Detail of the face of the angel in the Louvre’s version of Leonardo da Vinci’s “Virgin of the Rocks”. The heavy craquelure is, in part, a likely exacerbating consequence of the paint film having been (badly) transferred from panel to canvas by restorers at the Louvre in 1806. In any event, the persisting fragility and vulnerability of this surface has hitherto protected the painting from “restorations”, of which the National Gallery version of this painting (see Figs. 6, 7 and 8) has had two since the Second World War.

It seems to be being claimed now that scientific tests have shown that the painting can safely be restored. Given a) the extremely cracked and irregular surface; and, b) the extraordinary subtlety of the modelling that attaches to the individual fragments of the paint but works artistically across them and despite their physical and optical disruptions, it is hard to imagine what assurances “scientific analyses” might offer in support of taking the sheer risk of working upon such a painting with solvents which are notoriously invasive and pentrating and love nothing better than a good crack through which to advance themselves. Would a restorer attempt to clean each item of paintwork individually or work across several at a time while attempting to preserve the immeasurably subtle artistic relationships that would be out of sight underneath the solvent-laden and abrasive swab?

Above, Fig. 3: Detail of the face of the Virgin in the Louvre’s version of Leonardo da Vinci’s “Virgin of the Rocks”.
Above, Fig. 4: The mouth of the “Mona Lisa”. Those who would restore this painting, even in its present parlous state, might first recall Leonardo’s account of painting flesh values:

Put on the carnations with silk brushes, and while they are fresh you can make the shadows as vaporous as you will. The carnations should be painted with white, lake, and massicot; the shadow should be of black and matoric (massicot), with a little lake and black. When the picture has been sketched in lightly, let it dry and then retouch it with lake soaked in gum-water, and this should have been left some time in gum-water, because it is thus better, and will not have any lustre when it is used…”

The scholar of Leonardo’s painting techniques, Jacques Franck, has adduced that the “vaporous” subtlety of expression encountered here could only have been produced by minute touches of brushwork applied in multiple glaze layers, and has warned that with such a blur of superimposed micro-layers of vulnerable glazes, one could not be sure that the solvent used, even in the course of a very gentle cleaning, would not cause inevitable damage, whether in the ultra delicate zone of the mouth or elsewhere. As it is, any gum-bound pinks have long since faded or perished at restorers’ hands, along with the Mona Lisa’s eyebrows – which have survived on the Prado’s copy.

Above, Fig. 5: The top two images show changes made to the mouth and nose of a Titian at the Prado. Among the many solecisms introduced in this single “restoration”, the tip of the nose now terminates not in the centre of the philtrum (the groove that runs from the upper lip), as human anatomy decrees, but behind its far edge, in a quasi-cubist manner; the lower lip has been padded-out so as to swing entirely in a convex curve to the left terminus of the mouth; that terminus now sports two little creases, not one, thereby suggesting that the mouth turns both up and down.
The bottom three images show the recent changes made to a Veronese face at the Louvre that were detected and reported by Michel Favre-Felix of ARIPA.

Above, Fig. 6: Detail of the face of the angel in the National Gallery “Virgin of the Rocks”, above, after its recent cleaning but before retouching.
Below, Fig. 7, below, the angel after its recent cleaning and retouching, in which the far side of the mouth was turned down against art historical and technical (including x-ray) evidence.

Above, Fig. 9, and below, Fig. 10: Details from the National Gallery’s Pontormo “Joseph with Jacob in Egypt”, before (left, and top), and after two cleanings and restorations (right, and bottom).
These images are taken from the 1938 and 1990 editions of Kenneth Clark’s book “One Hundred Details from Pictures in the National Gallery”.

In between the two photographs (the post-cleanings photographs are grey-scale conversions from the large colour plate in the 1990 edition) this painting was restored twice by the Gallery, in 1940 and in 1981-82.
It was said of the first cleaning that it had been undertaken because the picture was “much disfigured by dark spots and discoloured varnish”.

The second cleaning was undertaken because “The picture is still blistering. There are numerous old small retouchings, obvious repairs along the cracks and a large hole in the green robe lower left…[and because there was a] discoloured layer of old varnish with some blanching.”

The treatment report after the second restoration read: “The discoloured varnish and retouchings were removed with propan-2-ol and white spirit leaving a thick greyish layer of surface dirt and varnish remnants which was removed with a potassium oleate soap. The blisters were laid with gelatine and the painting restored with pigments in Paraloid B-72 and varnished with Ketone-N.”

It should be said that we are greatly indebted to the National Gallery for making its conservation records and photographs available to us. In this particular case, in setting out the post, we queried our own scanned post-cleaning photographs and re-scanned them as a precaution. The second scan was identical to the first. Thus, in so far as the (Gallery’s own published) photographs are reliable, the viewer may fairly make here an appraisal of the artistic cost (in terms of lost tonal differences; lost modelling of forms; lost details – as in curls of hair, for example) that was paid for the removal of the disfigurement represented by spots of darkened retouching. Moreover, such trade-offs, which are surprisingly common in museum restorations, are rarely strictly necessary – or necessary at all. Jean-Pierre Cuzin, the former director of paintings at the Louvre who resigned from the St Anne advisory committee, was of the opinion that the discoloured touches on the St Anne could simply have been repainted. (The varnish had been thinned, replenished and regenerated on a number of occasions since the war.) Such retouching practices are common: aside from its two major cleanings and restorations, this Pontormo had simply been retouched in 1955 – and again in 1979, just two years before its second cleaning.

Perhaps the last word should be given to
Sègoléne Bergeon Langle who has recently commented:
As a general rule, I prefer old works to be cleaned only very lightly. You can never retrieve the original colours, what you get instead is the current state of the painting materials. Leaving a slight veil over the work makes it
more harmonious

The Louvre Leonardo Restoration Committee Resignations

The Great Louvre Picture Cleaning Controversy has crossed the Atlantic. Following the Guardian coverage reported in our previous post, the New York Times’ Paris Correspondent, Elaine Sciolino, today covers yesterday’s meeting (January 3rd) of the Louvre’s international advisory committee on the restoration of Leonardo’s “Virgin and Child with St Anne”. Ms Sciolino’s account likens the current internal professional crisis of confidence at the Louvre to the controversy over cleaning methods that followed in the wake of the restoration of Michelangelo’s Sistine Chapel ceiling frescoes in the late 1980s and the 1990s.

The departure from the Louvre’s advisory committee of two such eminent authorities as Ségolène Bergeon Langle, the former director of conservation for the Louvre and France’s national museums, and Jean-Pierre Cuzin, the former director of paintings at the Louvre, comes at the moment when the “Virgin and Child with St Anne” enters its second and (– as we have seen with the repainted angel’s face in the National Gallery’s version of Leonardo’s “The Virgin of the Rocks”) inherently perilous phase of retouching. Louvre spokesmen, in their official justifications for a provocatively radical and inescapably controversial cleaning, are seemingly in denial of the significance of the events now reverberating around their heads.

Madame Bergeon Langle’s timely and sagacious warning that “Despite great progress in our competence we need to be driven by modesty. Better and more controllable materials are yet to be discovered” can only give heart to those critics who have been horrified by the Gadarene Scramble for newsworthy restorations in which too many major museums and galleries have already participated.

“Few problems are more controversial than the problem of how to restore a painting. I have never encountered a practitioner of the craft who approved of the work of another.”

~ Bernard Berenson

Above: the Louvre’s (unfinished, c. 1508-10) Leonardo da Vinci “The Virgin and Child with St Anne”. In return for the loan of the Louvre’s version of Leonardo’s “The Virgin of the Rocks”, the National Gallery is to send its (brittle and fragile) Leonardo Cartoon (“The Virgin and Child with St Anne and the Infant St John”) to the Louvre, to accompany the unveiling, after cleaning and restoration, of the “Virgin and Child with St Anne” – so many cross-polinating risks being undertaken by so few, so insouciant, curators.
