The Sistine Chapel Restorations, Part II – CODA: The Remarkable Responses to Our Evidence of Injuries; and Thomas Hoving’s Rant of Denial
Before considering the third and concluding part of our examination of the Sistine Chapel ceiling restoration, it might be helpful to note the responses made to the first two posts (“Setting the Scene, Packing Them In” and “How to Take a Michelangelo Sibyl Apart, from Top to Toes”). Without exception, these have comprised outright expressions of support and/or of indignation and distress at the fate of the frescoes. Such phases as “I had no idea”, “I was horrified to see” and “that things were so bad” abound. Serious and intelligent websites have reported our accounts in similar terms. As is discussed below, no one has challenged our evidence of injuries and everyone who has responded has been shocked and alarmed by it.
Bob Duggan on the Big Think site expressed this concern with precision: “When I learned that my very breath and perspiration could contribute to the slow destruction of the frescoes, I felt sad. However, when I read Art Watch UK’s accusation that the Vatican undertook a 20-year restoration project of the frescoes ‘in full knowledge that the stripped-down bare fresco surfaces would thereafter be attacked by atmospheric pollution unless given some other protective covering’ (which has not yet happened), I felt rage over the local mismanagement of a global cultural treasure…” Duggan added that he was “reminded of a similar, more recent restoration fiasco involving Thomas Eakins’ The Gross Clinic. Years after the artist’s death, overzealous conservators stripped away darkening varnishes applied by Eakins to reveal the brighter colors beneath that were more in line with the Impressionism then en vogue.”
Ikono, an organisation dedicated to democratizing art through the production and broadcasting of short films that present art to the wider public sphere, reported that “ ‘The Vatican authorities are in conservation crisis today because they stripped the Sistine Chapel frescoes bare in the 1980s and 1990s. They did so against material and historical evidence that Michelangelo had finished off his frescoes with additional glue or size-based a secco painting,’ writes Artwatch in an excellent two-part article on the Sistine Chapel Restorations…”
Our case was re-presented in the pithiest form imaginable on the Left Bank Blog: “OY! According to ArtWatchUK: ‘The Vatican authorities are in conservation crisis today because they stripped the Sistine Chapel frescoes bare in the 1980s and 1990s. They did so against material and historical evidence that Michelangelo had finished off his frescoes with additional glue or size-based a secco painting. That original, autograph material was removed in full knowledge that the stripped-down bare fresco surfaces would thereafter be attacked by atmospheric pollution unless given some other protective covering. An attempt to coat the frescoes with synthetic resin (Paraloid B72) was abandoned leaving some surfaces clogged and the rest unprotected. The authorities then promised to install hi-tech paraphernalia that would somehow prevent the polluting atmosphere from making contact with the Chapel’s painted walls and ceiling. As was shown in our previous post, that cockamamie promise was not delivered. Today, in a chapel increasingly over-crowded with paying visitors, these stripped-down frescoes stand in greater peril than ever.’”
A number of questions arise. If the import of the evidence we have assembled over the past 23 years is so clear to so many, why does it have so little traction with the authorities who sanctioned the affronting restorations? Does the absence of any challenge to our evidence mean that everyone is now (privately if not openly) persuaded that – quite aside from the present and ongoing environmental assaults within the chapel – Michelangelo’s painting has indeed been gravely and irreversibly injured artistically, in terms both of its individual component parts and its general orchestration of effects? Or does it show that the authorities, in pursuit of their own interests, are now impervious to and politically insulated against any criticism?
When we first began making this case over two decades ago in the dark pre-digital era, the ink was scarcely ever dry on our criticisms before someone or other claimed that our comparative photographs were misleading; that old painted, drawn, or engraved copies of the ceiling were not to be trusted and had no force as testimony; that we were technically ignorant, or victims of “culture shock”, or agents of mischief – or worse. Could it really be, as it still sometimes seems, that no matter how grave and persuasive the evidence of injuries might be, there exists a wider disabling public resignation and conviction that nothing might today impede the lavishly funded, sponsorship-attracting, Conservation Juggernaut?
To be institutionally specific and somewhat blunt: could it be that the Vatican authorities today think it better to continue sheltering behind a fantastical fairy story of the transforming powers of Wicked Soot and Imperceptibly Darkening Varnishes, than to concede a professional misjudgement made by a small group of in-house experts over a third of a century ago?
Our colleague in France, the painter and the President of ARIPA (The Association Internationale pour le Respect de l’Intégrité du Patrimoine Artistique), Michel Favre-Felix, adds weight and urgency to these considerations with a two-fold reaction. In the first instance, he too was startled by our further evidence of “this incredible statement by the chemist: ‘Ammonium carbonate alone tends to tone down colours…sodium carbonate livens them up’”, and the little-noticed admission of the ferocity of the cleaning agent AB 57 by the chief restorer and co-director of the restoration, Gianluigi Colalucci: “Here’s a tiny patch where I left it on too long. In this little experimental patch you see completely solid violet paint, but around it you can see the gradations of dark and light, which are the shadings of Michelangelo’s own work”. As Favre-Felix notes, whenever a given chemical is known to have even the slightest effect on the original colours, it is rightly forbidden to use it.
His second and generous reaction was to offer further visual corroborations in the form of evidence produced for ARIPA’s journal Nuances of other damages made on the monumental figures of the Sistine Chapel ceiling. The injuries to one of these, the Cumaean Sibyl, are of great strategic significance in our joint battles. That is, we have just shown in our two previous posts the gross damages inflicted on two of the greatest figures that came at the end of Michelangelo’s cycle when he was at the height of his conceptual, painterly and figurally inventive powers – his Libyan Sibyl and his Prophet Daniel (see Figs. 2 and 3). To that catalogue of injuries, the further evidence of this third case must surely now establish an indisputable and irresistible critical mass? Of the ceiling’s twelve alternating Prophets and Sibyls that constituted Michelangelo’s most heroic monumental and spiritually expressive achievement, we can now demonstrate how three in a row of these painted colossi suffered grievously. Statistically, a sample of a quarter might be considered sufficient to make a general case? We could, God willing, pursue the evidence further if necessary, but is it not now time sufficient for the Vatican to confront and address past heritage preservation errors and desist from what would otherwise constitute an effective falsification of scholarship and art history?
The Portuguese online newspaper Publico reported our criticisms of the Sistine Chapel’s restorations on the second of March. Professor Charles Hope, a former director of the Warburg Institute, was quoted in further criticism of the restoration. The present director of the Vatican Museums, Antonio Paolucci, conceded a pressing need for ameliorative environmental measures which he said would shortly be announced. Unfortunately, he nonetheless and bullishly defended the restoration itself as one which will last for centuries – even before any measures have been announced. (We understand that since those comments were made, the promised announcement has retreated from this April to “the end of the year”.)
If we might at least now be sure that the Vatican is aware of our criticisms and evidence, we recognise that for its part, the Vatican will also appreciate the potential material and political risks of abandoning defences of the restoration. Visitors to the chapel greatly swell attendances to the Vatican Museums. In 1976, about 1.3 million people visited the museums. By 2007 the number had reached nearly 4.3 million, netting some $65 million and providing the Vatican City with its most significant source of income. An admission of error would also embarrass the many major players within the international art world who proclaimed a Revolutionary Restoration in the 1980s. To what degree of embarrassment might be sensed in an ill-tempered and defensive outburst by (the late) Thomas Hoving, a former director of the Metropolitan Museum of Art, New York, in a filmed interview for a portrait of the late painter Frank Mason, an early critic of the restoration and a founding member of ArtWatch International.
Thomas Hoving and selected dialogue from an interview in the film A Light In The Dark:
00:53:02 – Thomas Hoving:
“He doesn’t know what he’s talking about (Frank Mason). There’s a guy at Columbia, some professor who’s been screeching about this for years. (pause) Turns out that he just doesn’t know what he’s talking about. (pause) Do you think Michelangelo was honestly going to deliver it to the Pope something that looked dirty?! (laughs) His marble was going to look gray, his marble was going to look blackened out?! You think that he really mixed his fresco to look like that?!”
01:07:01 – Alexander Eliot:
“I wouldn’t say that the Sistine ceiling had been destroyed myself. I wouldn’t use that word. I would say that it had been desecrated.”
01:07:24 – Thomas Hoving:
“I was part of the desecration personally, if this idiot is right. I am part of it so he ought to put my name on it. (pause) I was invited by the man who cleaned it, Paolucci – whoever, (pause) [Gianluigi Colalucci was the chief restorer and co-director of the restorations, which ran from 1980 to 1994. Antonio Paolucci became the Director of The Vatican Museums in December 2007. – Ed.] to come up in the rickety elevator (makes sound effect of elevator) all the way to the top, and he gave me a beautiful fresh sponge, dipped it in the solution and (he) said OK clean. And they were finally doing the Separation of Earth, (uh) Separation of Light and Darkness, the last one. They started with the Flood and worked backwards. I said, ‘What?’ He said, ‘Ya, try it.’ I went (reaches up) ‘shooo!’ (wiping motion) And this thin film of black just disappeared.
“It was just built up soot over hundreds of years from the stoves that they used to drag in there when the Cardinals all had to meet. That’s what they all did. They had little cubby holes, their servants had cubby holes, they had tents, they had bunks, full service catering, and stoves.
“And fresco is impervious to anything other than being blasted by (uh) laser beams you know (does sound effect) out of Star Wars. Not only did they not desecrate or ruin it, they didn’t do anything to it that wasn’t there. So the guy is full of shit (!) if he said that they damaged the Sistine ceiling in any way, they didn’t! I know it. I was there. I cleaned about eight inches of the Sistine ceiling – personally!”
01:10:11 – Thomas Hoving:
“It’s not a controversy, the guy is full of it (Alex Eliot) He’s never been there, he’s never seen it. Did he clean a part of it?”
Interviewer Sonny Quinn: – “He made a film…”
Thomas Hoving: “Big deal.”
SQ: “He was close enough so he…”
TH: “Close enough? It’s about 55 feet, give me a break!”
SQ: “…they built scaffolding for him and he was there for six weeks…”
TH: “During the cleaning?”
SQ: “No, before the cleaning…”
TH: “Ya, so?”
SQ: “Well, he wanted everybody to examine his film and…”
TH: “Ah the guy is just full of it…”
For the record (once again), in 1967 the art critic and writer Alexander Eliot and his wife Jane Winslow Eliot spent over 500 hours making a close-up documentary film of the ceiling, The Secret of Michelangelo, Every Man’s Dream. Eliot was up there on the scaffold, every bit as close to the ceiling as Hoving was to be – and for much longer. On 20 May 1985 Eliot had pleaded with the Vatican’s Secretary of State for him to view the Vatican’s own copy of the Eliots’ film and to “have it stopped at the images of the Ancestors [on the lunettes]. Compare what it proves was there against what’s left today”. That precious record of the unrestored ceiling awaits a re-showing. One can only wonder why the Vatican never pressed the testimony of that filmed footage of the pre-restoration ceiling in support of the later cleaning.
For footage of the cleaning itself in progress, see the Ikono site mentioned above which links to three short films. The narrations of all are unspeakably hagiographic and tendentious: critics of the restoration are said to have been “divided”, while the restorers displayed a “passion for their task that recalls that of Michelangelo himself”. The restoration’s outcome is said to “speak for itself” and to have answered “all but the most severe critic”. Most brazenly of all, an outing for that old canard: this restoration had provided “rich opportunities for study”.
We should perhaps resign ourselves to the possibilty that the Eliots’ film may never be aired again – but it will never be possible to expunge all the photographs of the unrestored frescoes that permit the kind of directly comparative visual analysis routinely conducted on this site. Such comparisons truly do “speak for themselves” because they permit like fairly to compare itself with like. For those with eyes to see, such photo-comparisons will forever tell the same heart-breaking story: a misconceived, technically aggressive restoration inflicted grievous injuries on Michelangelo’s art.

Review: Renoir at the Frick – The Curatorial and Conservational Photographic Blind Spots
The Frick Collection’s recent temporary exhibition “Renoir ~ Impressionism and Full-length Painting” contained ten pictures and took ten years to assemble. It was organised by the deputy director, Colin Bailey, to showcase the The Promenade, the museum’s sole and “somewhat overlooked” Renoir – “overlooked” because Henry Clay Frick’s entrenched prohibition against loans had prevented the picture from travelling to major Renoir shows such as the 1997-78 “Renoir Portraits” exhibition which Bailey had organised for the National Gallery of Canada, Ottawa, The Art Institute of Chicago and The Kimbell Art Museum, Fort Worth. If the Promenade could not join the international party then the party might come to the Frick.
For this celebration of a single work nine major pictures were borrowed from seven museums and Bailey, a distinguished scholar of French art, produced a book/catalogue that contains much illuminating material on contemporary costume and fashionable mores. As delightful as the show itself ought to have been, the experience proved dispiriting and alarming. Partly, this was because such temporary compilations of dream combinations always come with downsides and a common glaring omission. In this case, for several months a gallery-full of important Frick pictures were bumped from view as important works from other, also temporarily depleted, museums were put at risk. The Musée d’Orsay, for example, sent both its Dance in the City, which had been transferred from its original canvas and relined (see Figs. 10-13 and below), and its Dance in the Country, across the Atlantic. The National Gallery (London) sent its already travel-damaged The Umbrellas, and did so at a time when it had lent its brittle, fragile, shotgun-blasted, “never-to-travel” Leonardo Cartoon to the Louvre. The Columbus Museum of Art, Ohio, lent its fire-damaged Madame Henriot “en travesti” (The Page)…and so forth.
The omission that is common to all borrowed compilations was the failure – perhaps for reasons of institutional politesse – to take the opportunity to assess the relative physical conditions of the variously treated and restored cross-section of pictures from within an oeuvre or, in this case, from a specific moment within an oeuvre – “the decade of Impressionism”. This commonly encountered lacuna was the more apparent because Bailey himself discusses conservation matters rather more than most. He does so, however, as a seemingly grateful recipient/beneficiary of museum restoration departments’ technical largesse and their routinely delivered “discoveries”. With his prefatory expression of deep gratitude to an international slew of conservators for “their participation in undertaking technical examination on the paintings in their charge and for allowing me to publish their findings in this catalogue” we knew precisely what critical appraisals not to expect.
Strictly speaking it would not be necessary to call for comparative assessments on such occasions if museums were all, as a matter of course, completely frank about the restoration-injured conditions of individual works. By way of an example of what might be discussed at a time when recollection of the show is still fresh and when armed with Bailey’s book/catalogue, which is as intensively researched and handsomely illustrated as might ever be expected, we consider here the technical history, in so far as it has been disclosed, of just one of the nine loaned pictures – Renoir’s beautiful invention of arrested intimacy-in-movement, his Dance in the City.
The obvious starting point for any appraisal of a picture’s successive states should be the earliest photographic record of the work. With Renoir we enjoy an immense if not comprehensive photographic record. We even have film footage of him painting and sculpting. We have contemporary or near-contemporary photographs that show his paintings in the context of close proximity to other paintings and in a common light (Fig. 1). When the testimony of early photographs differs markedly from presently photographed states (as so often is the case with modern masters – see Figs. 3-7), then, self-evidently, there is an issue crying to be addressed.
When, for example, we compare the very different states of Renoir’s Dance in the City, as seen in Figs. 3 & 4, despite making allowances for photographic variations (such as the great discrepancies of size between the earlier and later images) and being mindful of Bailey’s own thanks to the photographer Michael Bodycomb for having “improved the quality of almost every image”), it is clear that the painting today is not the work that it once was; that its values and relationships have changed. Consider the floor on which the dancers perform: then, it was more varied in its tones; today it is more equal. Then, the floor to the right of the ball gown was darker than the floor to the left of the couple. That darkness served to emphasize the sweeping profile at the back of the trailing gown. Reading downwards from the waist, the shape of two convex masses of material formerly made a leisurely elegant descent towards the train. Today, that “materially” expressive clarity of design in the lower of the two draped forms has been quite disrupted, if not lost, as the now lighter tone of the floor merges with the now diminished shaded tints of the gown (see Figs. 3, 4 & 11).
For all of Bailey’s admirably close (and expertly advised) attentiveness to the dress-making “mechanics” of the gown – “…The skirt is draped in puffed folds (en bouillonée) with a tier of drapery in the front and two pleated flounces at the bottom. The long train is is draped and pleated to form poufs in the back, and a petticoat can be glimpsed beneath it” – he misses the weakened and possibly redrawn profile. Bailey well describes Renoir’s preoccupation with costume. As the son of a tailor and a seamstress, how could that artist have been unaware of or indifferent to the expressive “cut” and sweep of a costume on a swirling, waltzing figure? Previously, the costume of the male dancer was more various in its tones. Today it reads as a uniform black appendage to the female dancer. Previously there had been no hint of the present overly-assertive, sharpened and darkened treatment of the coat tails which pictorially are now as disruptively emphatic as the head of a claw hammer.
For Bailey, the now lighter toned, more equal floor is “immaculate”. To a charlady that might well seem gratifyingly the case, but Renoir, as Bailey acknowledges, fretted greatly about establishing integrated relationships of figures and backgrounds. As Renoir himself put it: “I just struggle with my figures until they are a harmonious unity with their landscape background, and I want people to feel that neither the setting nor the figures are dull and lifeless.” (“Renoir by Renoir”, N.Y., 1990, p. 50). “Harmonious” sometimes seems to be an elusive concept to non-artists. It is not synonymous with “more-alike”. Rather, it describes the uniting through an artistically forged equilibrium of otherwise potentially disparate, disjunctive elements. We constantly see in artists’ preliminary, intimate sketches how their very first thoughts attempt to anticipate and resolve the requirements of such pictorial equilibriums – see Figs. 8 & 9.
Rendering Renoir’s dance floor more homogeneous has had a spatially flattening and pictorially deadening effect. Rendering it both generally lighter and more equal has contributed to the unfortunate effect of detaching the couple from their swirling space and leaving them as isolated and self-contained as a pressed flower in a book. Indication of the painter’s pictorially melding preoccupation is unmissable in the small oil sketch at Fig. 9 that Renoir made for another of his dance paintings. Compared with the earlier state of Dance in the City, the present one resembles an artificially sharpened photograph.
With apparent injuries we must always look for causes and look for them behind as much as within official accounts. As mentioned, and as Bailey euphemises, this picture has “had a complicated structural history”. That is, it has been both transferred and relined. Both operations are highly dangerous. When the paint film was detached from (its presumably original) canvas, the restorers took the opportunity to photograph the painting from the back of the paint, capturing the image in reverse. This image is excitedly presented as having afforded “a rare glimpse into Renoir’s initial preparations…we can see the lines demarcating the back and the train of the womans dress” (but see comments and photograph at Fig. 10). In the same vein, an X-radiograph “shows how enegetically Renoir laid out both his figures and the background elements”. Bailey discusses an infrared reflectogram (Fig. 11) and acknowledges that these “technical” images were made by the Laboratoire du Louvre, C2RMF. Our colleague in ARIPA, Michel Favre Felix, advises that a certain number of paintings coming from the Louvre or from “l’Orangerie”, were “more or less restored” in 1986 on entering the Musée d’Orsay. Bailey confirms that the picture entered the Louvre in 1979 and was transferred to the the Musée d’Orsay in 1986 but offers no details on any restorations of the picture. The pronounced differences in the picture that are evident in Figs. 4 and 13 would however suggest that a restoration took place at some point after 1986.
Needless to say, Renoir painted from the bottom up with overlaid patches of paint and his final, most considered statements therefore formed the upper visible surface of the original paint film. That original, considered and final surface (as was best seen and recorded in the earlier photograph at fig. 2), is no longer to be found in current photographs or in the flesh. Whatever interest penetrative imaging might have, it is secondary in importance to the actual appearance of pictures to the human eye. The current escalating vogue for “technical” imaging that probes beneath the surfaces of pictures serves to divert attention from destructive restoration actions on pictures’ critically important upper surfaces. If the present international museums merry-go-round of borrowings makes the need to address the condition of paintings impolitic, then that is a further compelling reason for curtailing it.

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.”
