The Twilight of a God: Virtual Reality in the Vatican
It seems that there is to be yet another make-over at the Sistine Chapel. It seems that, for the Vatican, you can never have too much colour, or too bright a supply of lights – or too many paying visitors – in the Pope’s private chapel. It seems that aesthetics are now under the control of technicians and bean-counters. Michelangelo is to suffer further indignities. The recent falsification of his work by “restoration” is now to be artfully compounded by bespoke hi-tech boutique lighting.
On 7 November, the Times’ business section broke the news that the Sistine Chapel is about to be illuminated by no fewer than 7,000 new LED lights (by courtesy of technical wizards at Osram and EU Research funding). Their purpose is to “enhance” the experience for visitors (see Fig. 1, “Judgement day for a bright idea”). In the FT Weekend Magazine it is claimed that the 5m tourists who now pack into the chapel each year will “have a far better view” (Mind/Science: “Illumination: New Light on Michelangelo”, 30 November 2013). This is on the grounds that, while the present lighting creates a “low-contrast twilight that fails to bring out the colours in Michelangelo’s masterpiece”, the replacement will facilitate “a completely new diversity of colour”. This diversity is to be the product of artificially selective sources of lighting, quite unlike anything found in nature and unlike previous systems of artificial light used in churches and chapels.
There are two things wrong here. The first is that Michelangelo’s colours have already been forced chemically into a false chromatic intensity by the misconceived and radically intrusive restorations of the 1980s and early 1990s. As we have repeatedly demonstrated (see bottom right), the homogenised applications of solvents-saturated cleaning gels stripped away the artist’s own tonal modifications of colour and intensification of shadows, even though there was abundant evidence that this part of the frescoes was original work that had been recorded during the artist’s own lifetime and throughout the frescoes’ history. (On the aesthetically destructive impact of the cleaning method, see Figs. 3 and 4.) Second, this proposed attempt to flood the Chapel with artificial light constitutes a bizarre “own-goal” act of revisionism on the part of the Vatican.
That is, the defence offered at the time of the controversial restoration was that the new and startling colour effects (which many critics likened to Disney animation stills) had been calculated by Michelangelo himself so that his images would cut through the gloom of a smokey chapel. On that initial rationale there can be no aesthetic or historical justification today for flooding the Chapel with artificial stage-lighting that is to be ten times more powerful than the existing artificial lights.
In the December 1987 Apollo, the Vatican’s official spokesman/consultant on art historical matters, Prof. Kathleen Weil-Garris Brandt, conceded that the “transformation of Michelangelo’s mysterious dark frescoes, half visible but so familiar (at least from reproductions), into blazing, colouristic pyrotechnics… is attracting the most public attention and controversy.” Nonetheless, she insisted that Michelangelo had “modelled his forms by means of colour” – this, despite the fact that his contemporaries had been united in the contrary conviction that he had done so by his unprecedented powers of light and shade. One apologist declared in December 1987 that all previous Michelangelo scholarship had been prey to what he dubbed “the Darkness Fallacy and the Sculptural Fallacy”. It was further claimed that the revolutionary chemical excavation of the “New Michelangelo” was “one of the great revelations of our time” and that it required nothing less than the rewriting of art history.
Given this recent history, might Prof. Brandt – or any of the restoration’s supporters at that time – ever have imagined that within a couple of decades the Vatican would conclude that the chromatically brilliant “New Michelangelo” would require artificial lighting ten times more powerful than that installed at the time of the restoration? If that seems inconceivable, let us turn the question round. Has there been in recent years any loss of chromatic intensity in the bare, stripped-down fresco surfaces that were left exposed for the first time in their history to the air-borne pollution of Rome? If not, why, as the FT reports, was it thought necessary to analyse Michelangelo’s surviving pigments so that each one of the 7,000 new lights might be individually attuned to a spectrum that suits the said, specific pigments precisely as and where they are encountered on the present ceiling – and in the present “twilight that fails to bring out the colours in Michelangelo’s masterpiece”?
This proposed adjustment of lights for the purpose of chromatic enhancement rather creepily resembles the use of projected light to simulate the original condition of colours that had faded in Rothko’s Harvard murals. The authors of a paper delivered at the 2011 Lisbon ICOM conference on this particular usage on modern paintings, concluded that theirs is: “A novel restoration technique that uses colored light from a digital projector to compensate for color alteration… To the authors’ knowledge, this approach has not been used previously for the restoration of paintings.” So we ask again: Has the Vatican been monitoring the colours of Michelangelo’s frescoes since the last restoration? If it has, have any changes and deteriorations been detected – and is this lighting system designed to compensate for them? Could the Vatican be attempting to launch by stealth what will be the world’s first non-secular virtual restoration?

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.

The Sistine Chapel Restorations, Part II:
How to Take a Michelangelo Sibyl Apart, from Top to Toes
“I must confess I harbour a lingering almost subconscious fear that someday someone will come, unexpectedly, with a really intelligent observation that will show all of us to have been blind.” ~ Gianluigi Colalucci, 1990
We were startled when the Vatican authorities admitted that Michelangelo’s Sistine Chapel frescoes are in greater peril than at any point in their history. Powerful art institutions rarely broadcast their own embarrassments. More often, they see off their critics by sitting tight, quietly briefing journalistic proxies and…continuing to be. Welcome as was the acknowledgement of the problem by Antonio Paolucci, director of the Vatican Museums, casting the Chapel’s paying visitors as the principal cause of the present crisis, masked greater institutional responsibilities.
The Vatican has yet to acknowledge that this environmental crisis arose as a direct consequence – and within just two decades – of permitting the Chapel’s ancient frescoes to be used as a test bed for the then new and highly controversial cleaning agent “Mixture AB 57″. And, despite the brouhaha over toxic visitors, there remains no hint of acknowledgement that the restorations of the 1980s and early 1990s proceeded on an art critical misreading which, in addition to stripping the fresco surfaces bare and leaving a chemical time-bomb within the Chapel, inflicted grave and irreversible artistic injuries on Michelangelo’s paintings – see right.
On the cleaning method’s toxic conservation legacy, we had precisely warned in 1993 that: “even if the Vatican team were to concede that the brilliance of Michelangelo’s new colours is a chemical deceit purchased at the cost of a physical and chemical weakening of the frescoes, the dispute would not be laid to rest. The need to avoid further deterioration would still be there.” (James Beck and Michael Daley, “Art Restoration: The Culture, the Business and the Scandal”, Chapters III and IV.) In similar vein we can now say that today’s promises of dramatic technical “improvements” are simply recycled 1980s assurances that, at best, remain of a palliative nature. Even when promised the first time around, the Vatican authorities had admitted to us (see below) that the measures could not fully solve the then already pressing environmental problems unleashed by the restoration’s experimental method.
The Experimental New Picture Cleaning Method
AB 57 was developed by Professor Paulo Mora and his wife Laura Mora, chief conservators at Rome’s Istituto Centrale del Restauro, for cleaning stone buildings. It comprised: “a mixed gelatinous solvent, consisting of a solution of ammonium bicarbonate, sodium bicarbonate, Desogen (a surf-actant and anti-fungal agent), carboxymethylcellulose (a thixotropic agent), dissolved in distilled water.” Toti Scialoja, a painter and a former professor at Rome’s Academy of Fine Arts, complained that its ingredients were “too powerful – ammonia and soda, the stuff you use to clean your bathtub”. Professor Christoph Frommel, director of the Bibliotheca Hertziana in Rome, described it as “a sharp and aggressive chemical”.
The Moras presented AB 57 as a means of removing insoluble salts and incrusted materials from wall paintings: “If the original surface of the painting is unaffected by water then this mixture will have no deleterious action on it”. Michelangelo’s frescoes did not suffer greatly from incrusted and insoluble salts but they were extensively covered with water sensitive glue/size painting which artists, conservation experts and scholars held to comprise Michelangelo’s own final painted adjustments. An early sign of the wrongness of the new cleaning method came when the restorers abandoned customary claims of a miraculous “recovery” of original and authentic conditions. The use of AB 57 had produced such a mismatch between the cleaned frescoes and the early copies that had been made of them, that the hype had to be bolder and of a different order. As seen in our previous post, the decision to clean with AB 57 had been taken quickly and in express excitement at the prospect of overturning art history itself. This dramatic technology-led change of conservation philosophy was reported in a 1983 Newsweek account: “As recently as 1976 while cleaning paintings by the other artists on the side walls of the Chapel, workers deliberately kept the colours muted so that Michelangelo’s wouldn’t look too faded by comparison. ‘Even then it entered nobody’s head to start on Michelangelo’, says master restorer Gianluigi Colalucci. But when a new cleaning solvent was developed, Colalucci tested it…”
Selling the Surprising AB 57-induced Changes to Michelangelo’s Painting
Having used it, the resulting rupture between the old Michelangelo and his restored self was trumpeted by Fabrizio Mancinelli, the Vatican Museums’ curator and co-director, with Gianluigi Colalucci, of the restoration. Mancinelli claimed in 1986 that the restoration “had brought to light (and will continue to bring to light) a totally new artist, a colourist quite different in character from the unnaturally sombre character who has in the past fascinated generations of historians, connoisseurs and fellow artists…The cleaning of the frescoes has led to the surprising conclusion that the kind of suggestive painting by shadows for which Michelangelo was admired until a few years ago was essentially the product of candle smoke and still more of glue varnishes applied possibly even before the 18th century.” (“The Sistine Chapel ~ Michelangelo Rediscovered”, p. 218.)
Even though no evidence was ever produced of extensive glue applications having been made by restorers, in the early years, art historians and credulous art critics queued to repudiate what one scholar dubbed the “Darkness Fallacy” and the “Sculptural Fallacy” of traditional Michelangelo studies. The proclaimed “New Michelangelo”, however, was an entirely modern chemically engineered artefact, not a scholarly construct. In fact, it flew in the face of the historical record: Michelangelo had been celebrated at his own funeral not for any colouristic brilliance – let alone for, as one critic recently held, the “sharp and acid palette used by Michelangelo in the Sistine Chapel” – but for his “fleeting, sombre colours”. The new art historical dispensation rested on a twentieth century purging of aged, sometimes distressed but nonetheless authentic material. Indeed, it was precisely because this was not a historically-informed recovery of an original state that drums had had to be rolled for “The New Michelangelo”.
It was claimed that this revisionist reading of historical and material evidence had been corroborated “scientifically”. But this was a New Science to sanction a New Michelangelo. Scientific examinations of the frescoes in the 1930s by X-ray and ultra-violet imaging techniques had led to altogether contrary conclusions. It was reported in 1938 that Michelangelo’s “overpaintings were lying quite brightly a secco on the fresco layer itself; these overpaintings proved themselves undoubtedly the painting of the Master himself.” (See “Art Restoration”, Chapter III.) It was further claimed that Colalucci and his colleagues had recovered the original fresco surfaces so deftly that they had preserved its “original” patina and even left a thin layer of dirt above them that would protect the new surface from airborne pollution. Well, we all now know from the present panic in the Vatican that that assurance was not worth a used solvent swab and that a couple of years ago “unimaginable amounts” of dirt were scrubbed off the frescoes by conservators working at night so as not to impede the daytime tourism stream.
The Over-Selling of Conservation Science
Conservation science has its uses but it can never analyse or appraise works of art because Art’s essential properties are aesthetic not material; perceptual not mechanical. Insofar as there might be a science of art, it is to be found in art itself and within artists’ own practices. This is because art consists not so much of materials as of values and the relationships between values that artists’ create and orchestrate, albeit, with materials. These values are aesthetically relative, not intrinsic to materials, and they are continuously appraised and adjusted by artists as they work. Self-criticism, self-analysis and continuous aesthetic appraisal are integral to the making of art. With art, critical and analytical faculties can never be replaced by apparatuses or be donned by technicians. Conservation science might sometimes tell us of what something is made but never by whom it was made.
The Mis-Appliance of Conservation Science
In terms of professional art restoration, conservation science can serve a useful diversionary purpose. The restoration-authorising authorities and art lovers alike can be invited to put aside critical responses on an implicit assurance that some inscrutable but infallible force has guaranteed the probity of whichever of the many conflicting restoration methodologies is being used at that moment. We ArtWatchers are not inclined to be so trusting nor so easily led. In the case of Michelangelo’s Sistine Chapel ceiling, having examined evidence of the cleaning method and its consequences for two and a half decades, and being now armed with the officially published accounts, we are confident that not only can it be shown that Michelangelo’s tonal/plastic systems were recently injured, but that even his very designs, his drawing, his vaunted disegno were repeatedly violated and corrupted.
A Catastrophic Loss of Art Citical Nerve
These losses and violations were not so much unfortunate by-products of an inappropriately aggressive cleaning agent as the consequence of prior and catastrophic failures of art critical judgement and powers of aesthetic analysis. This failure was evident not only within the Vatican’s curatorial, scientific and conservation staffs, but throughout much of the wider international art historical establishment. By effectively agreeing to “de-attribute” what were – and had always been recognised to be – the last stages of Michelangelo’s own work, an overly deferential art historical establishment sanctioned their destruction. For all this (initial) pan-national consensus, the judgement was historically rogue. In 1986, when defending his own restoration, the chief restorer, Gianluigi Colalucci admitted that his professional predecessors’ judgements had been contrary to his own and “not encouraging” to the restoration. That was an understatement: restorers who had worked on the previous restoration (1935-36) had officially and flatly reported that Michelangelo had “finished off a secco”, that is, that he had painted on top of his frescoes when they had dried.
The Testimony of Charles Heath Wilson
Restorers who had worked on the restoration of 1904 had abandoned attempts to clean the frescoes for fear of damaging Michelangelo’s vulnerable work on the surface. Colalucci, greatly in thrall to contemporary “scientific” analysis, dismissed such official reports as “subjective impressions”. He also ignored the testimony of the British painter and fresco expert Charles Heath Wilson who had reported his own close-hand examination of the ceiling in an 1876 book “Life and Works of Michelangelo Buonarotti”. Wilson had found the frescoes “extensively retouched with size colour…evidently by the hand of Michelangelo”. He found that this secco painting “readily melted on being touched with a wet finger and consisted of a finely ground black, mixed with a size probably made according to the usage of the time from parchment shavings.” He further noted, “The shadows of the draperies have been boldly and solidly retouched with this size colour, as well as the shadows on the backgrounds…The hair of the heads and the beards of many of the figures are finished in size colour …These retouchings…constituted the finishing process or as Condivi [Michelangelo’s preferred biographer] expresses it, alluding to it in the history of these frescoes, ‘l’ultima mano’.”
For Wilson, there could “be no doubt that nearly all of this work is contemporary, and in only one part was there evidence of a later and incompetent hand.” Aside from its artistic force, certainty about the secco painting’s antiquity lay in an elegant technical proof: “The size colour has cracked as the plaster has cracked”. It is a matter of record that the ceiling cracked before any restorers touched it. If, as has been claimed, later restorers had repeatedly applied glues, those glues would inevitably have been brushed into the pre-existing cracks. Wilson, who tested the depth of the cracks with a penknife, saw that none had been. Artists like Wilson appreciate that it is impossible to paint over a cracked surface without working the material into the cracks. Wilson was left in no doubt: having been applied when the ceiling was new and not-yet-cracked, these surface glue paints could only have been Michelangelo’s own work, his finishing stages, his l’ultima mano. Normally, restorers recognise that when varnishes or paints can be shown to have run into age-cracked materials this can be taken as a proof of their more recent origins. On this occasion, the restorers failed to recognise the implications of the converse.
The Vulnerability of Michelangelo’s Glue Painting
Moreover, this original secco work, Wilson appreciated, was water-sensitive, having been damaged when “washed by labouring men with water in which a caustic has been mixed”. As to when the alleged restorers’ glue-varnishes might plausibly have been applied, no evidence was forthcoming. In 1996 Colalucci said that although “countless attempts at cleaning and restoration seem to have been made”, only “four are actually accounted for”. The four are of 1566, 1824-25, 1904 and 1935-36. As we showed in our post of 1 April 2011, that first restoration itself provided the clearest possible evidence of Michelangelo having painted shadows a secco. That evidence, taken together with the copies of the ceiling discussed opposite should have been an end to the matter. The last two restorations cited by Colalucci coincide with photographic records and these, too, offer no support for the claimed superimpositions of secco painting and glue-varnishes by restorers.
Perplexed by the Vatican’s unwavering but evidently unsupported insistence that the ceiling had repeatedly been coated with glue “varnishes”, I asked in May 1990: “Does any documentary evidence exist to support the claim that hot animal glue was repeatedly applied to the frescoes over the centuries in order to revive the colours?” Colalucci replied that there was none. In 1986 he had reported a note in a manuscript which described how the ceiling had once been cleaned with linen rags and bread “scrubbing hard, and sometimes when the dirt was more tenacious, the bread was moistened a little” but added “That is as much as it says. The note does not mention at all the use of substances to revive colours or of glue varnish.” (See “Art Restoration”, pp. 74-78.) If, as Wilson discovered, the secco painting dissolved at the touch of a wet finger, an earlier hard scrubbing with wet rags or bread would certainly have been sufficient to cause the injuries that Wilson and others had reported to parts of the ceiling.
A Filmed Corroboration of Wilson’s Testimony
Wilson’s appraisal was echoed from another scaffold a century later. 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”. Alexander Eliot reported in the April 1987 Harvard Review how “with the exception of the previously restored Prophet Zachariah, almost everything we saw on the barrel vault clearly came from Michelangelo’s own inspired hand. There are passages of the finest, most delicately incisive draughtsmanship imaginable. Michelangelo’s loving depiction of fingernails, eyelids and tiny wrinkles stand in contrast to tremendous swirls of colour…” 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, now historical, record still awaits a re-showing.
Venanzo Crocetti’s Protests Against the Restoration – as a Sculptor and as a Former Restorer in the Sistine Chapel
In 1989 the sculptor Venanzo Crocetti, who had spent “four full years” working during the 1930s as an apprentice restorer on the scaffold, published three photo-comparisons of the cleaned lunettes in an article in the December Oggi e Domani (“Salviamo Almeno il Giudizio Universale”) – see Fig. 28. Crocetti’s account was detailed and technically informed. He began by explaining how he had appealed unavailingly in 1983 to the director general of the Vatican Museums, Prof. Carlo Pietrangeli, to desist from incurring the “rapid biological degradation caused by the cleaning power” of AB 57. Crocetti flatly dismissed claims that the glues had been applied by restorers. He also testified that as early as 1983 applications of AB 57 had been standardised at 3 minutes each, regardless of local conditions (see below). He complained of the folly of cleaning aggressively in small patches, zones that had originally been made with very broad applications. These glue-paint applications, he noted, had been made chiefly in the shaded parts of the figures and to such artistically selective purpose that Michelangelo’s authorship was beyond question. As a (formerly) supreme case in point, see Fig. 1.
The Effects of the Double Applications of AB 57
Crocetti’s testimony on the AB 57 cleaning method then being used on Michelangelo was particularly damning. He noted that while the first 3 minutes long application left the frescoes looking cleaner, the second on the following day, left them with altered and considerably degraded colours. He believed that the first applications effectively “degreased” the surfaces leaving them open to greater penetration by the second applications. He was convinced that the immediately apparent visual effects of these twin applications would not be their final outcome. He argued that their corrosive actions would continue because of the absorption of the solvents to a depth of half a centimetre. Some days after the second applications he noticed (from the scaffold itself) the appearance of “whitish oxidations of variable intensity” over large zones.
He considered the restorers’ claimed discovery of “stratifications of dirt gathered on the frescoes over the centuries” exaggerated and misleading, and he held that the early photographs of the lunettes by Anderson made the extent of this exaggeration clear – see Fig. 28. He believed that the ferocity of AB 57 made any finely tuned cleaning gradated to meet local conditions impossible. He believed that the greatest injury was to the chief feature of the frescoes – their disposition of lights and shades, and not their local colours. He believed that the restorers, in their pursuit of more intense colours, had penetrated the frescoes to their brighter, less modulated preparative layers. He felt confident that he had seen at first-hand how, with “cleaning”, the figures in the lunettes had been remade, becoming “false in form and colour” alike. He saw that many of the shadows from which the figures had formerly emerged had simply disappeared. He saw that corrections which Michelangelo had, with mastery, made invisible, had been exposed (in particular, see Figs. 11-16). Above all, he confirmed that the condition of the frescoes remained “excellent”, and that this was in part due to the absorption over the centuries of greasy substances of chapel smoke which had “strengthened the colour. Leaving upon it a glittering shift of the lightest varnish [thereby counterbalancing] the aridity and fragility” of old fresco. Having worked on the restoration in the 1930s, he found himself near to despair.
The Invasive Ferocity and Likely Legacy of AB 57
The AB 57 water-based paste used to remove Michelangelo’s size painting contained two “caustics”: sodium bicarbonate and ammonium bicarbonate. Professor Frommel had questioned the method of application: “Who knows if they succeed in cleaning this completely away? No one can prove whether or not it will affect the frescoes in the future. No one can say definitely if they get all of it off.” Consider Colalucci’s own account of the method of application:
“The times of application, rigorously measured, were:
First application: 3 minutes, followed by removal, washing with water. Left to dry for 24 hours. Second application: 3 minutes, followed by removal, washing and leaving to dry as before. If necessary, and locally only, small applications, followed by plentiful final washing.
In the case of salt efflorescences consisting of calcium carbonate, there was added to the solvent mixture a saturated solution of dimethylformamide…”
Chemically Adjusting Michelangelo’s Colours
AB 57, a calcium dissolving solvent, was thus used to remove organic materials with an oven-cleaner like ferocity and speed even though many experts held those very materials to comprise authentic Michelangelo work. Contrary to assurances otherwise, the aesthetic consequences of this stripping extended, as Crocetti had observed at first hand, into the very fabric of the exposed fresco surfaces. This was a serious matter. The Vatican’s research chemist, Nazzareno Gabrielli had explained that AB 57 contained two separate salts because while “Ammonium Carbonate alone tends to tone down colours…sodium carbonate livens them up”. The Moras’ combination, he judged, had “the proper chromatic effect”. So far as we know, it was never explained by what means the “proper” combination for Michelangelo might have been established.
Juggling with dangerous chemicals and processes constitutes professional chic in some restoration quarters. Restorers often claim that a dangerous chemical in “safe hands” is better than a mild one in “untrained hands”. When restorers speak among themselves, the professional conceits are more evident. The IIC Bulletin carried an obituary on Paolo Mora who died on 27 March 1998. He had studied under Mauro Pelliccioli, who restored Leonardo’s Last Supper, and, reportedly, was fond of claiming that he could clean a picture with a broom and drugstore chemicals. When he found himself too busy to clean a large Bellini altarpiece, Pelliccioli enlisted two students and showed them how to dissolve rods of caustic soda in water. He demonstrated his cleaning technique by sweeping a swab of soda over the picture with one hand followed immediately by a “neutralising” swipe with a turpentine swab with the other. Thus enlightened, the students were said to have “cleaned the large painting in a single day”.
The AB 57 Rinse-Water Menace
Aside from exposing the stripped fresco surfaces to the Chapel’s notoriously polluted atmosphere, yet other risks were taken in pursuit of brighter colours. Removing the water-based solvent gel with copious amounts of washing risked, as Frommel feared and Crocetti had observed, depositing corrosive ingredients within the frescoes. The “highly soluble” ingredients were said to have been selected because “they are easy to wash off”. It was certainly desirable that they should be so: carboxymethyl cellulose is known to encourage sodium retention; ‘Desogen’, being a detergent as well as fungicide, is non-volatile and does not evaporate. The Moras had conceded that these ingredients have “the disadvantage of remaining in the painting unless removed after treatment by rinsing with water”.
There are problems with washing, however. First, the rinse water was absorbed deeply into the porous fresco and with it, inevitably, particles of soluble and corrosive ingredients. Twenty four hours were needed for the water to evaporate before a second application of AB 57 could be applied. Second, tap water may contain solutions of sodium, iron, copper, and chloride, and unless it is packed with sufficient calcium bicarbonate, will itself attack the calcium carbonate of fresco. Even distilled water (which is free of impurities) slowly dissolves calcium carbonate and attacks the frescoes’ structure. When challenged in 1991 on having introduced dangerous materials into the frescoes, Colalucci replied: “AB 57…has been greatly tested and is very old. The actual solvent is held within a gel which does not allow the particles of the actual solvent to penetrate the plaster and the colour. However, the gel is removed and only a minimal (if any) percentage might remain which has no influence on the colours.” In 1986 Colalucci disclosed that, at that date “The work was concluded with abundant rinsing, repeated at intervals of up to several months” and that only “The last rinsing was done with distilled water”. Much copious washing was thus carried out with tap water.
Mirella Simonetti on Dangerous Deposits and their Air-Borne Allies
Far from having “no influence”, experts expressly feared that residues deposited within the frescoes by rinsing would react with airborne pollutants and moisture. The restorer Mirella Simonetti held one of AB57’s ingredients, bicarbonate of soda, to be an “extremely damaging” residue because, when combined with the sulphates of calcium and air-borne sulphuric anhydrites, it produces sodium sulphate – a whitish dust which corrodes the fresco and destroys its coloured surface. Simonetti also maintained that the use of EDTA (ethylene diamine tetra acetic acid) within the solvent gel had chemically altered the fresco by causing a “breakdown in the molecular structure [and] bringing about a disintegration [which] in turn causes the division of the components and the discohesion of the lime.” Once weakened in this fashion, the disintegration would continue – and “even water can favour such a process”. Simonetti’s alarm was later vindicated when, tests showed that the compound’s corrosive properties etched the surface of marble into irregular corrugations, scattering light and imparting a deceiving effect of brightness that provided more routes of ingress to airborne pollutants.
Fresco Painting and Its Known Enemies
It had long been recognised that air-borne sulphur attacks fresco. In 1884 the reverend J. A. Rivington explained in a paper delivered at the Society of Arts in London how air contaminated by coal and gas emissions destroys fresco: “The carbonate of lime is converted into the sulphate, breaking up the paint and becoming itself disintegrated in the process of change.” The notoriously contaminated air surrounding and invading the Sistine chapel contains sulphur dioxide from coal-burning, nitrous oxides from car exhausts and hydrogen chloride from incinerated plastics. When combined with rain or condensed water these substances produce sulphuric, nitric and hydrochloric acids respectively, all fiercely corrosive. Water is brought into the Chapel by tourists in the form of perspiration and breathing vapour while breathing itself gives off carbon dioxide.
On 12 December 2012, Corriere della Sera reported: “‘Dust, temperature, humidity, and carbon dioxide are the great enemies of paintings’, Museum Director Antonio Paolucci told reporters in the Vatican, ‘so this threat is something we have to address. The five million tourists who visit the Sistine Chapel each year bring massive amounts of grime and humidity with them, and it is seriously damaging Michelangelo’s frescoes. So starting in the middle of 2013, every tourist will be thoroughly vacuumed, dusted, cleaned, and chilled before admission to reduce the amount of environmental pollution they cause.
‘On entering the chapel, each tourist will be required to pass through a hi-tech vacuum system to remove dust, fibres, skin flakes, hair and other tiny particles, before they are allowed to view the frescoes. At the same time, a special carpet will also clean their shoes, while side vacuums will cool their temperature, to reduce the heat and humidity that emanates from their bodies. The dirt and heat generated by the 20,000 bodies each day has caused grime to accumulate on the paintings, and a thick layer of dirt had to be scrubbed off of the Last Judgment two years ago. This cannot be allowed to happen again.’”
What Goes Round, Comes Round
We have been there before. In “Art Restoration” in 1993 we wrote: “A recent report commissioned by the Vatican on the Chapel’s microclimate noted that the very large numbers of tourists produce the following adverse effects: they carry in from the streets polluted dust and organic particles on their clothing and hair; their combined body heat raises the temperature by as much as 5°C; and they greatly increase the relative humidity of the air. The moisture and carbon dioxide given off by tourists combines to produce carbonic acid which dissolves the calcium carbonate of the fresco. Water vapours convert sulphur particles into sulphuric acid which also dissolves fresco. The body heat creates convective air currents which carry polluted particles up to the walls and ceilings. Water vapour can activate the traces of salt and detergent left behind after the cleaning with AB57.”
In 1981 Colalucci had equated the glue/size paints with “extraneous chemical substances” without which “and with the science we have today” he hoped “the frescoes will remain in good condition for a very long time”. As mentioned, he offered an assurance that he had left “a very thin film of dirt touching the paint surface with its varying ‘patina’. This fine layer of dirt acts as a form of protection to the paint.” As also mentioned, we now know that whatever Colalucci might have left behind performed no such service, and that dirt on frescoes is no protection from further accumulations of corrosive dirt.
There have been many unfounded assurances. In 1987 Kathleen Weil Garris Brandt, Professor of Fine Arts, at New York University’s Institute of Fine Arts, and spokeswoman for the Vatican on the restoration of Michelangelo’s Sistine Chapel frescoes, assured readers in Apollo that, “The substances used for the cleaning…have been used successfully for over twenty years… their chemical action is known and stops once the process is finished…the cleaning chemicals do not actually come into contact with the fresco surface”. Just months before in the Summer 1987 Art News, Summer 1987, the Moras themselves had claimed no more than that placing the solvents in a cellulose gel helped to “reduce penetration into the fresco”. In the summer 1987 Art News, the assurances were becoming more specific. M. Kirby Talley Jr., an independent consultant in fine art, interiors and art conservation, wrote:
“In order to prevent the condensation of moisture on the surface of the fresco, the Vatican has already embarked on an extensive programme to control the micro-climate of the Sistine Chapel. Professor Camuffo of the University of Padua spent a year making detailed measurements of relative humidity, temperature and air movement. A climate-control system based on his findings, which will prevent the movement of air above the windows as well as filter it, is now being developed by Carrier-Delchi. Electrical heating coils, ‘A sort of giant electrical blanket,’ as Persegati called it, will be placed under the roof above the ceiling, and will help to maintain a steady temperature during the winter. A dirt absorbing carpet has already been installed on the stairs down to the chapel and on part of the floor inside. Carrier-Delchi is considering a wind shower to remove dust particles from people’s clothing before they enter the chapel. Low heat lamps that can be adjusted to the amount of natural light entering through the windows will further reduce the temperature.”
Synthetic Resins – On or Off?
Talley Jr. reported that Colalucci had assured him that Michelangelo had used no secco paint on the lunettes, and that while the synthetic resin B 72 had been used to seal the walls of the lunettes it had not been used to that purpose on the ceiling. Even the official apologias for B 72 were more disturbing than reassuring: “Like all restoration materials it has its good and its bad points”, Talley said. Frommel was quoted as saying “According to the critics B 72 is something which may become opaque in the future. Are the critics right when they say we don’t know what it will do? They say tests should have been made and then a long period of time should have been allowed to elapse before proceeding. Paraloid can close the surface to respiration. It can close the pores, and if that were to happen it might change the interior life of the fresco.” To this Talley gave voice to B 72’s champions. According to the Moras “If you don’t use Paraloid, what do you use? Organic resins and inorganic fixatives such as lime water, ethysilicates and barium hydroxide all have serious drawbacks. Of the synthetic resins the acrylics are the best, and of the acrylics Paraloid is the least bad.” Was the least bad, good enough for Michelangelo – and better than his own secco painting which had for centuries protected the fresco surfaces from airborne pollutants?
On this question, the Vatican’s accounts prove unsatisfactory and shifting. All that can be said safely is that B 72 was abandoned and not replaced at some point between 1986 and 1991, at which latter date Colaucci claimed “There was no final application to protect or saturate the painting”. This change of mind was defended in 1991: “Our decision not to apply a protective material derived from the awareness that any new material which is not homogeneous with the original components of the fresco will undergo rapid degradation, causing, in the best of cases, aesthetic damage.” This being so, we must expect some parts of the frescoes to deteriorate more rapidly than others – but how many? In 1991 Colaucci put B 72 applications at “lunettes 50 per cent, ceiling 3 per cent”. In 1993 (“Art Restoration” p. 120) we had noted that while protection of the frescoes was to depend on the thin layer of original dirt that Colalucci claimed to have left in place and on the above described plans to stabilise and purify the chapel’s microclimate: “When Michael Daley asked if the air-conditioning system would eliminate the great fluctuations triggered by tourists, he [Mancinelli] replied ‘No. It will reduce the peaks and the troughs but will not eliminate the problem entirely.’” Of course, at that date, as today, the problems could have been halved by halving the numbers of tourists. Then, as perhaps still is the case, on days when the Chapel was closed to visitors, visitor numbers to the Vatican museums fell by 60 per cent.
The Breach of Methodological Good Practice that Menaced Michelangelo’s Shading
In the execution of the cleaning, certain procedural lapses compounded the risks and dangers. Early in the programme (in 1981 when working on the lunettes), Colalucci had said that AB 57: “was created mainly for marble but the Moras experimented with it on fresco. It is like paste. It can be on for a minute or ten minutes. The effect varies with the amount of time it spends in contact with a surface. The danger is that if you leave it on a minute or two too long it will go beyond the foreign substances and start removing the paint. You can see little areas where I’ve applied AB57 in two or three stages. Each time I take it off well before it’s too late. Then I look at it and gauge how much more time it will need…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.”
Why, then, were the varying thicknesses of the (mis-designated) “foreign and extraneous substances” all given identical applications of two three minutes-long applications set twenty-four hours apart? Such an uniform treatment of so vast and varying a programme of painting seemed to breach conservation’s own ethics and “good practice”. As we had reported in “Art Restoration”:
“Within four years, Colalucci had abandoned this control of the solvent by constant observation and timing. In its place a standardized procedure was adopted, described in the 1986 ‘General Report on the Lunettes’: ‘First application, three minutes followed by removal and washing with water. Left to dry for 24 hours. Second application, three minutes followed by washing and leaving to dry as before’. These three-minute applications were said to have been ‘rigorously measured’. Colalucci explained the reason for the change of procedure: the size of the ceiling required that work be carried out by a team. Individual restorers, responding to the evidence of their own eyes, would draw different conclusions. Therefore, in order to obtain a ‘homogeneity of result’ – a ‘primary objective’ – they must be denied the opportunity to judge for themselves how long the solvent should remain in place. Solvent applications had to be predetermined, Colalucci felt, in order to avoid ‘either emotional involvement or complex mechanical manipulation on the part of the restorers’. When asked in 1985 at the Wethersfield Conference in New York why he did not adjust the timing to what his eyes were witnessing, he replied: ‘Because emotional or subjective conditions must not be permitted to intrude upon science.’ The scaffold, he added, did not permit stepping back to assess effects and the continuous bright lights of the Japanese film-makers ‘fatigued one’s eyes’. The activity of the film crews was itself a distraction as was also his having to entertain up to sixteen VIP visitors a day…” See Figs. 34 and 35.
Conservation Ethics and Showbiz Restorations
The inventors of AB57 held that cleaning should never be considered “entirely a technical matter…confined merely to the choice of solvent”. The restorer’s responsibility for the control of the solvent’s actions is absolute and should never be left to “depend on the natural uncontrolled action of the products” and must always depend on “the precise wish and aim of the restorer guided by his critical interpretation”. By failing to exercise control at all times, the restorer “deprives himself of the principal alarm signal when faced with new situations; he gives up looking ahead and allows the problem to resolve itself mechanically so that subsequently he can impose the result as an accomplished fact.”
By test-driving a new cleaning agent under television studio conditions in a constricted, over-crowded and art-politically febrile space, the Vatican restorers pioneered a new professional genre: conservation as both entertainment and professional swank. The combination of the Nippon Television Corporation sponsored showbiz and a provocatively radical restoration drew many protests. This spawned intensely propagandistic promotional razzmatazz, the unprecedented scale and character of which will be examined in Part III.
“The activity of restoration can be defined in terms of two overlapping headings, procedure and method. Procedure is fixed and invariable, and consists in the scientific planning and execution of the restoration project, regardless of the material involved. Method, however, is the department strictly of the action taken in the course of the restoration, and is therefore variable, subject to factors arising from the material, technique and state of conservation of the monument involved.
“The adoption of a procedure which governs the progress of the work is characteristic of modern restoration. Under the impetus of a marked development in technological expertise, modern restoration has extended its established and primary function of conservation for aesthetic ends to include a research capacity, directed towards the work of art considered as an inseparable duality, conceptual and material.
“In the past restoration practice aimed at cancelling out the effects of time and events upon the work of art, termed by Brandi comprehensively its historical aspect, absolute priority was given to its aesthetic aspect, conditioned of course by its contingent situation. The restoration of works of art was therefore entrusted to artists, who were free to introduce personal methods, often secret or private, consistent with the aim of returning the work to its pristine material state, but not necessarily to its original intended state.
“In the evolution of the ‘art’ of restoration, the laboratory for the Restoration of Pictures in the Vatican Museums has had a not insignificant role. Founded in 1992 by Biagio Biagetti according to the latest ideas, and subsequently provided with a Laboratory for Scientific Research, the institute is today directed by by Carlo Pietrangeli who in 1978 established its guidlines in Rules for the restoration of works of art.
“In June 1980 this laboratory, constitutionally responsible for the restoration of the pictorial patrimony of the Holy See, qualified and informed by its enormous experience, which goes back more than 50 years and has been constantly renewed both technically and in terms of personnel, undertook the most important task it had yet undertaken in its history, the restoration of the frescoes of Michelangelo in the Sistine Chapel…” ~ Gianluigi Colalucci, “Michelangelo’s Colours Rediscovered”, “The Sistine Chapel – Michelangelo Rediscovered”, London, 1986.
“The restoration of Michelangelo’s frescoes in the Sistine Chapel was a venture that shook the very foundations of the art world more than any other single event has managed to do in the last quarter of a century.
“Promoted and conducted with rigorously conservative objectives, over the course of its execution the restoration program assumed an ever-growing significance in historical and critical terms – an importance that was foretold when the first patches were cleaned and was fully confirmed by the restoration of the Eleazar-Mathan lunette.” ~ Gianluigi Colalucci, “Michelangelo The Vatican Frescoes”, by Pierluigi de Vecchi and Gianluigi Colalucci, 1996.
“…The intuition that the colours must have been quite different from those that could be seen can be found sporadically in the writings of the more perceptive scholars of Michelangelo, from [Charles Heath] Wilson to Biagetti and Wilde. But clear and conclusive evidence of the original colours was established for the first time in recent times by the extraordinary photographs of the Japanese photographer Takashi Okamura, taken just before the restoration and published in a book of 1980, unfortunately in a small limited edition and now not widely seen. The eye of the camera, in itself much more acute than the human eye, and aided by much stronger light than is usually available in the Chapel, revealed beneath the dirt and deteriorated glue-varnish the tangible existence of of what the restoration today is gradually retrieving.
“Although the book with Okamura’s photographs and the restoration that is now proceeding came about independently and for different reasons, the two are complementary, and Okamura’s book is today a valuable record of what for centuries had masked the true nature of Michelangelo’s painting; if the cleaning had not gone ahead, it would have been the sole means by which to achieve a proper or effective analysis of his work…” ~ Fabrizio Mancinelli, “Michelangelo at Work”, “The Sistine Chapel Michelangelo rediscovered”, London, 1986.

The Sistine Chapel Restorations: Part I ~ Setting the Scene, Packing Them In
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 (see right and our posts of 1 April 2011 and 12 November 2012). 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 (see Appendix below). 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 (see caption at Fig. 4). As was shown in our previous post, that cockamamie promise was not delivered. Today, in a chapel increasingly over-crowded with paying visitors (see Fig. 1), these stripped-down frescoes stand in greater peril than ever.
Ironically, the “cleaning” of the ceiling, which arguably constitutes the greatest single restoration calamity of the 20th century, occurred at a time when picture restorers had skilfully rebranded themselves as safe, scientifically validated “conservators” of all that is valuable – even though Kenneth Clark had recently admitted to having founded the National Gallery’s science department in the late 1930s in order to dupe the public and wrong-foot restoration critics. A grandly titled “Laboratory for Scientific Research” had been created at the Vatican in 1922 on the “latest ideas” but during the 1980s Italian restorers admitted that running technical “tests” before restorations was professional “window-dressing” because it was always known in advance which materials were to be used.
Some restorers sincerely believed in the scientific hocus pocus that supposedly had trumped anachronistic and unacceptably “subjective” aesthetic responses. The appointed chief restorer of Michelangelo’s frescoes, Gianluigi Colalucci, was one such, insisting that: “Emotional and subjective considerations must not be permitted to intrude upon science”. At that time the Vatican’s curatorial and administrative authorities may not have sufficiently appreciated the extent to which every restoration of a great work of art is an accident waiting to happen: a collision of sublimity and incomprehension made tangible. In 1993, at the beginning of the fourth chapter of the JamesBeck/Michael Daley book “Art Restoration: The Culture, the Business and the Scandal”, we asked:
“If authentic painting by Michelangelo has been lost in the course of a scientific restoration, many questions need to be answered. Did a blunder occur because of or in spite of the use of a scientific approach? Has too great a dependence on scientific data undermined crucial powers of aesthetic discernment and judgement? Is the scientific method of restorers rigorous or slipshod? Is the scientific status of modern conservation legitimate or bogus? Do restorers always follow their own ground rules?”
In the last twenty years it has become clearer that the claimed scientific underpinnings of picture restoration methods were spurious and that an appreciation of the workings of art and its internal relationships is not to be gained through some analysis of material components in a laboratory, however highfalutin and expensive the “investigative” or “diagnostic” apparatus may be. Beyond its conceptually simplistic and aesthetically impoverished terms of reference, the very reporting of “scientific” conservation methods has lacked both critical rigour and methodological consistency. In practice conservation science has provided a flag of convenience under which fundamental artistic questions can be evaded while ever-more ambitiously grandiose, lavishly funded and spectacularly transforming projects are launched. The authorities at the Vatican seemed quite oblivious of the ease with which even the most modest restorations can escalate into dangerous and irreversible treatments.
In 1964 Dr Deoclecio Redig de Campos, the Vatican museums’ curator and director of restorations, launched a cautious cleaning of the 15th century frescoes by Perugino, Botticelli, Ghirlandio, Rosselli and Signoreli on the lower parts of the Sistine Chapel’s north and south walls. After 15 years, that programme led to the cleaning of two minor 16th century frescoes by Matteo da Lecce and van den Broecke on the east wall. By that date, direction had passed to Dr Fabrizio Mancinelli, the new curator (and soon to be, with Colalucci, the co-director of the Nippon Television Corporation-sponsored restoration of all of Michelangelo’s Sistine Chapel frescoes). As we reported in “Art Restoration”, Mancinelli decided that “Redig de Campos’s cautious policy of removing only part of the layer of grime and foreign substances…was not appropriate in this situation.”
What Mancinelli deemed appropriate was that the minor frescoes should be cleaned with the new aggressive cleaning compound AB 57, even though this would obliterate original painting applied a secco by the artists onto their frescoes when dry. Curiously, Mancinelli’s justification for this removal of authentic and historical material was primarily aesthetic. That is, he held that a cautious cleaning and repairing of the damaged original secco paints would give only “disappointing results” compared with what might be attained by what he termed “a more radical cleaning”. We should be absolutely clear: “radical” was a euphemism for stripping the paintings down to their bare fresco surfaces in order to introduce heightened (but inauthentic) colours. Although the programme was to prove unethical by restorers’ own professional codes, Mancinelli persuaded the authorities that the visual “gains” to be had by trading original material for chemically brightened colours on those two minor works would outweigh even a directly consequential need to “return to the side walls and [do] a more thorough job there too.” (Just as the slowest ship determines the speed of a convoy, so in decorated chapels the most brightly scrubbed surface sets the overall level of cleaning. Michelangelo’s fate was sealed.)
While restoring the east wall works in 1979, a single test of AB57 was made on one of Michelangelo’s lunettes (see Fig. 8 and, for the consequences, Figs. 4-7). Professor Carlo Pietrangeli, the director of the Vatican Museums, said in 1982 “the results were so encouraging that it was decided to take on the whole ceiling. By the summer of 1980 the work had begun.” As Pietrangeli told Patricia Corbett in the May 1982 Connoisseur, once AB57 was shown to deliver chromatically transformed frescoes, “No one was able to resist the temptation”. In 1987 Dr Walter Persegati, the Vatican Museums secretary and treasurer, said in the Bible Review “These tests brought forward such colours that we were both scared and excited…It was decided that the procedure developed for the cleaning of the van den Broeck and Matteo da Lecce was applicable to Michelangelo’s frescoes. Therefore, we decided we had to do it.”
Note that because it had been decided that it could be done, it was “therefore” also decided that it should be done. In Part II we investigate the means, the methods and the artistic consequences of that novel application of a new cleaning agent to the very old, very precious decorated surfaces of the Sistine Chapel. In doing so we also show why the Vatican’s curators were right to be scared.
“A major purpose of the conference was to underline a basic truth: the conservation of any work of art is doomed to failure unless equal emphasis is given to its past and its future vicissitudes…Scientists and historians worry that conservators can be too ready to intervene, too impatient of prior tests, and insufficiently heedful of future dangers.” ~ Kathleen Weil Garris Brandt, Professor of Fine Arts, at New York University’s Institute of Fine Arts, and spokeswoman for the Vatican on the restoration of Michelangelo’s Sistine Chapel frescoes, reporting the proceedings of the “London symposium on the conservation of wall-paintings” in the November 1987 Burlington Magazine.
“There is therefore much concern about the future of the frescoes, given that no protective layer has been applied in this campaign (the controversial use of paraloid was abandoned at an early stage of the cleaning of the lunettes). The Vatican has decided to seal the windows and introduce an air-conditioning and filtration system. Doubts were expressed at the conference. Could the threat from faulty air-conditioning be worse than the threat from atmospheric pollution and mass tourism? ” ~ Caroline Elam, editor of the Burlington Magazine, reviewing the 1990 symposium on the Sistine ceiling restoration held in Rome to give preliminary consideration to the cleaning of Michelangelo’s “Last Judgement”.
“A ‘drunken herd’ of ‘unruly’ tourists is damaging Michelangelo’s famous Sistine Chapel paintings, one of Italy’s leading arts figures claimed as the pope prepared to mark the 500th anniversary of the iconic frescoes’ creation.
Some 5 million people visit the chapel every year – sometimes as many as 20,000 in a single day — and an increasing number of experts are now arguing that mass tourism is damaging the paintings.
Despite a major, 14-year-long restoration project in the 1990s, they claim that the breath, sweat, dust and pollution brought in by visitors dramatically changes the Chapel’s humidity and temperature – factors to which frescoes are particularly sensitive…” ~ Claudio Lavanga, NBC News, 31 October 2012.

The “World’s worst restoration” and the Death of Authenticity
When news broke of the 81 years old painter Cecilia Gimenez’s disastrous restoration of a painting of Christ in her local church, the world fell about laughing (see Figs. 2 to 5). The distressed restorer has taken to her bed as people queue to see the now infamous monkey-faced Christ and, wishing to preserve the hilarity, over 5,000 wags have signed a petition to block attempts to “return the painting to its pre-restoration glory” – as if such an outcome might credibly be in prospect.
With one honourable exception (Fig. 1) commentators failed to grasp that while this debacle is an extreme case it is not an aberration within modern art restoration practices. To the contrary, adulterations of major works of art are commonplace, seemingly systemic products of a booming, insufficiently monitored international art conservation nexus. In our previous post it was shown both how a steamboat painted by Turner sank without trace during two top-flight restorations at the US Sterling and Francine Clark Art Institute, and, how Renoir’s oeuvre is being traduced across museums. Here, to show that it is not just in sleepy Spanish churches that paintings are risk, we reprise a few of the professional art world’s own most radically controversial – and officially sanctioned – restorations.
The Observer columnist, Barbara Ellen, having good sport with the Spanish Incident (see Fig. 2), hoped a wave of copycat vigilante restorations (“Let’s nip into the Louvre and give the Mona Lisa something to smirk about”) would not ensue. Her nightmare has been “virtually” realised – Fig. 3. When saying that Ms Gimenez perhaps had not realised “that, as a rule, professional art restorers don’t start work with a bucket of Flash and some Brillo pads”, she assumed too much. While Brillo pads were skipped at the Sistine Chapel, bucket loads of oven-cleaner-like substances were repeatedly brushed onto and washed from Michelangelo’s Ceiling frescoes to the artistically injurious consequences described below and at Fig. 23. As we reported on April 1st 2011 – and that was no joke – the Vatican’s restorers’ own account of their experimental fresco cleaning method read as follows:
“…Removal of retouchings and repaintings with a mixed gelatinous solvent, consisting of ammonium bicarbonate, sodium bicarbonate, Desogen (a surf-actant and anti-fungal agent), carboxymethylcellulose (a thixotropic agent), dissolved in distilled water. Mixture acts on contact. The times of application, rigorously measured, were:
“First application: 3 minutes, followed by removal, washing with water. Left to dry for 24 hours.
“Second application: 3 minutes, followed by removal, washing and leaving to dry as before. If necessary, and locally only, small applications, followed by plentiful final washing.
“In the case of salt efflorescences consisting of calcium carbonate, there was added to the solvent mixture a saturated solution of dimethylformamide…
“Final treatment: the thorough, complete and overall application of a solution of Paraloid B72 diluted to 3% in organic solvent, removed from the surface of the pictorial skin by the combined action almost simultaneously of organic solvent and distilled water, which coagulates the surface acrylic resin dissolved by the solvent.”
A quick rinse with Flash might have been kinder.
There are three component parts in the professional restoration armoury: taking material off; putting material on; and, defending and promoting the said removals and additions with techno/aesthetic reassurances. Notwithstanding all supposedly science-validated self-justifications (reports on restorations are invariably written by the restorers themselves), the proper and appropriate test of a restoration is aesthetic appraisal of the resulting changes. It is reassuring that so many recognise that the transformation made to the Spanish painting shown at Fig. 5 constitutes a gross artistic injury. Perhaps the less extreme but also gratuitous injuries recently inflicted by restorers at the Louvre on the Veronese figure and face shown at Figs. 6 to 10 (and here reported on December 28th 2010) might also be acknowledged as the very crime against art and history that they constitute.
As shown at Fig. 10, even when the Louvre’s restorers were caught having secretly re-repainted the already repainted and publicly criticised Veronese face, the museum maintained a brazen official insouciance. The authorities do these things because they can and, presumably, because they do not know better. They ignore criticisms because they can and again, presumably, because they do not comprehend their force and their gravity.
In Figs. 11 to 26 we show the variously unfortunate consequences of restorers taking off and putting on material. (Like Tolstoy’s unhappy families, every unhappy restoration is so in its own way.) It is widely recognised in the art trade that pictures untouched or rarely touched by restorers enjoy better conditions than many-times restored works. For that reason, a high premium is placed on such rare but fortunate works. This reality notwithstanding, nothing seems capable of restraining the tide of restorations.
In Figs. 11 and 13 we see two successive restorers at work on the same figure in the same mural, Leonardo’s “Last Supper”, in Milan. It is a long-standing complaint that restorers thrive by undoing and redoing each others’ handiwork. In Fig. 11 the restorer Mauro Pelliccioli is removing paint with a knife. His restoration, the first post war intervention on the notoriously unstable mural, was highly acclaimed at the time. His philosophy had been to remove earlier restorers’ repaint where it concealed original paint-work by Leonardo, but to leave it in place when covering only bare wall (- see our post of February 8th 2012). In Figure 13 Pelliccioli’s former student and assistant, Pinin Brambilla Barcilon, is seen repainting Leonardo’s mural (- or, as restorers prefer, “reintegrating” the remains of original paint with fresh additional paint). Given that an estimated 80 per cent of Leonardo’s work had been lost and that Barcilon had aimed to remove all previous restorers’ handiwork regardless of whether or not original Leonardo paint survived underneath, she had to do massive amounts of repainting during her agonising two decades long restoration (see our post of March 14th 2012).
In Figs. 12 and 14 we see how dramatically differently two professionally linked Italian restorers, working just one generation apart, left the very same principal figure in Leonardo’s “Last Supper”. (What might be expected to survive or emerge from the next two restorations?) Like the 81 years old Cecilia Gimenez, Barcilon exercised artistic licence – albeit to a far lesser degree – during her painterly interventions on Leonardo’s remains. Where the cuff of Christ’s right sleeve had originally hung below and behind the table, for example, she painted it resting upon the table. To Christ, she too gave a new face and expression. The sole commentator to have recognised such continuums between extreme and lesser restoration injuries, the Sunday Telegraph columnist, Alasdair Palmer, wrote: “while the gulf between what modern restorers do and the dreadful hatchet-job done by Cecilia Gimenez is large, it is not always as vast as restorers would like us to believe”. He noted that while Pinin Brambilla Barcilon had done some magnificent work in recreating what she took to be Leonardo’s original picture, “it wasn’t a restoration because most of the paint applied by Leonardo had long ago disappeared”, and he cited an art historian who holds precisely that “The Last Supper is now a first-rate example of Barcilon’s work. It is not a Leonardo”. Palmer further notes that some of the most severe critics of recent restorations are other restorers:
“‘A great deal of restoration is incompetent,’ maintains Bruno Zanardi, professor of the theory and practice of restoration at the University of Urbino, and one of Italy’s most distinguished restorers. ‘Many of those who are let loose on great works of art do not know what they are doing: they have not been properly trained, and do not understand how fragile old pictures are.'”
To French and Italian transgressions many British and American ones might be added. At the National Gallery, London, it has been officially acknowledged that changes are made to pictures “primarily for aesthetic reasons”, and that while these aesthetic changes rest on the judgements of individual restorers whose “different aesthetic decisions” may result in pictures which “look very different”, all such results are considered “equally valid” (see “The New Relativisms and the Death of ‘Authenticity'”). In Figs. 15 and 16 we show a detail of the National Gallery’s Holbein, “The Ambassadors”. During its restoration (which, like that of Michelangelo’s Sistine Capel Ceiling, was a televised and sponsored event) the then head of conservation, Martin Wyld, took the opportunity to improve and, on “experts” advice, to change the surviving design of the Turkish carpet. In doing so, he paid scant regard to the aerial perspective that had previously been found in the picture. Ignoring the shadows that had previously been cast on the carpet, Wyld introduced a crisper, cleaner, flatter, more “on the picture surface”, altogether more abstract, modernist and, therefore, ahistorical version of Holbein’s original depiction.
More egregious were the changes made to Holbein’s anamorphic skull (Figs. 17 and 18). The cleaning exposed many losses of paint on the skull which bewildered the restorers and caused them to introduce – for the first time, to our knowledge – a piece of painted “virtual reality”. As we put it in a letter to the Independent (“Virtual reality art”, 29 January 2000):
“When the National Gallery recently restored Holbein’s The Ambassadors, the famous skull in the foreground was repainted to a new design not according to the laws of perspective by which it had been produced but after a computer-generated distortion of a photograph of an actual skull.
“This bizarre imposition of ‘virtual reality’ on to an old master painting is defended by the gallery on the grounds that ‘modern imaging techniques’ offer ‘more scope for exploring possible reconstructions’ than do the 16th century perspectival conventions by which the artist’s image had originally been generated.
“The difference between the original and the new parts has been concealed from the general public by the restorer’s attempt to integrate the handiwork of his own ‘tentative reconstruction’ with surrounding old paint by painting fake lines of cracking to match the old, actual cracks.”
In Figs. 19 and 20 we see the liberties taken by Wyld’s predecessor, Arthur Lucas, on Titian’s “Bacchus and Ariadne”. Lucas boasted to art students at the Slade School of Art that “there is more of me than Titian in that sky”. In thrall to new technologies and materials, Lucas took the trustees’ permission to reline the canvas, as authority for ironing the picture on to a double board of compressed paper. Such boards are today found to be unstable and will doubtless serve to licence further “urgent” conservation treatments.
In Figs. 21 and 22 we again show the startling changes made to a painting at the National Gallery of Art in Washington during the course of two restorations. During the first, as seen on the right of Fig. 21, a general weakening of values occurred. The woman’s necklace, for example, was dimished. As seen on the left in Fig. 22 , during a further restoration, part of the necklace disappeared. Rather than paint it back in, the restorer painted out the surviving section, as can be seen on the right.
When specific bits of paintings disappear restorers often claim that they were only additions made by earlier restorers. If such claims sometimes provoke scepticism, in the case of overall losses and degradations restorers usually offer no defences, seemingly hoping that curators, trustees, art critics, scholars and members of the public will be delighted or distracted by brightened colours and lightened tonalities. In Fig. 23, on Michelangelo’s Sistine Chapel ceiling, we see both the general lightening and brightening that attends an aggressive cleaning and losses of specific features and pictorially strategic values. Michelangelo had finished off his frescoes with additional glue or size-based painting but because the Vatican’s restorers held this to be either dirt or earlier restorations, it was all removed. Michelangelo had redrawn and remodelled the drapery seen on the left hanging from the figure’s right shoulder. It was washed off. The removal is shown to be an error by the testimony of earlier copies of the ceiling. (Rubens had copied the drapery as it was found before the recent cleaning.) Michelangelo sought to enhance sculptural effects to his painted figures by adding shadows that were seemingly cast by the three dimensional bodies he had depicted with contrasting brightly lit forms and dark, shadowy recesses and nooks. The latter, too, were lost.
Back at the National Gallery in London, we see in Fig. 24 similarly catastrophic general losses (in the course of another single restoration) of tonal gradations and modelling. In the case of the horse’s right nostril, we see the loss of the very aperture which formerly had carried air to the creature’s lungs. Alasdair Palmer points out that a comparison of the National Gallery picture with its sister panel in the Uffizi Gallery in Florence is shocking to behold. It is the more unforgivable because the National Gallery restoration was prompted by an earlier one of the Florence picture that had not flattened and weakened the horses.
The National Gallery’s great Velazquez, “The Rokeby Venus”, suffered dreadful injuries in 1914 at the hands of a suffragette (Fig. 25). That damage was as nothing when compared with subsequent injuries inflicted by restorers who here too (Fig. 26) were blind to artists’ manipulation of space; creation of atmosphere; rendering of form through calibrated tonal gradations. Before the gallery’s restorers had done their Cecilia Gimenez-esque worst, there existed a parity of brilliance in the two figures, with both displaying the seeming self-illumination of divinities. What sense of that miraculous evocation survives today? Little wonder that the previous owner of the picture made a scene at the National Gallery on sight of its “restoration” and protested that, had he known how it would be treated, he would never have sold it. His grievous personal loss-through-restoration was of a single picture. What price the world’s continuing collective losses at the hands of restorers?

Review: Stone-washed Renoirs and the Shock of the Undone
We knew at a glance that something was amiss. On June 16th, a newspaper photograph trailed an imminent auction sale of Renoir’s “Baigneuse” of 1888. Even on the evidence of that single de-saturated newsprint reproduction (right, Fig. 1) it seemed clear that the privately owned masterpiece had gone through the picture restoration wash cycle a time (or two) too often. A comparison of Christie’s pre-sale zoom-able online photograph with historic photographs of the painting further suggested that picture conservation’s would-be beauticians had been at work with swab and solvent: Renoir’s bather had been left (Fig. 2) a paler sugar-smooth pictorially and plastically enfeebled version of her original self. (For the picture’s appearance and condition in 1944, see Figs. 7 and 9.)
Just as museum curators who organise splashy temporary exhibitions rarely broadcast the “conservation” injuries borne by works loaned from sister institutions, so auction houses, which of necessity must act primarily as agents for owners, can seem no less reticent on this fraught subject. In practice, we find that in of both of these art spheres, the “now” is often implicitly presented as the “originally-was” and “always-has-been”, thereby thwarting what would be the greatest inducement to halt needless adulterations of unique historically-rooted artefacts: a full public disclosure of “conservation” treatments and frank art-critical discussion of their material and artistic consequences. By coincidence, recent museum and saleroom activities have brought to London a slew of little-seen examples of Renoir’s oeuvre. As cases in point of Renoir’s vulnerability, we examine here treatments of his “Baigneuse” of 1888 and the Washington National Gallery’s “The Dancer” of 1874.
Renoir’s “Baigneuse” was given star billing (on a £12/18m estimate) at Christie’s June 20th Impressionist/Modern sale, for the catalogue of which it provided the cover illustration (Fig. 2). While much was made in the eight pages long catalogue entry of an impeccable and unbroken provenance through ten successive owners, not a word was said about any restorations of the painting, and although many early photographs are identified in the picture’s literature, none is reproduced. It is disclosed that this Renoir is to be included in the forthcoming “catalogue critique” of the artist’s work being prepared by the Wildenstein Institute from the Archives of François Daulte, Durand-Ruel, Venturi, Vollard and Wildenstein. (Perhaps the present condition of the picture will be discussed in that publication?)
On the night of the sale, an announcement that the picture had been withdrawn drew gasps of surprise. Artinfo reported that the vendor had accepted a private offer from an unidentified buyer for an undisclosed sum somewhere within the estimate. Trade and press eyebrows have been raised at such secretive, pre-auction sales and the withdrawal was the more confounding because expectations of a big auction house “event” had been raised by extensive (and quite stunningly fetching) pre-sale press coverage with photographs of the painting enlivened by the seemingly routine inclusion of beautiful young female staff members.
With modern paintings, the starting point for any appraisal should be the earliest known photograph. Old photographs are historic records. Historic records should never be ignored. Old photographs of pictures assembled in homes or exhibition galleries are especially precious and instructive. The photograph of Renoir’s 1905 exhibition at the Grafton Gallery (Fig. 3) testifies not only to the then generally more vivacious relative values within individual works but to the striking variety of pictorial effects and painterly means deployed within Renoir’s oeuvre.
With regard to the photographic testimony of the original appearances of individual pictures, consider first the large, near-central painting in the 1905 Grafton Gallery photograph – Renoir’s “The Dancer”. This picture, now at the National Gallery, Washington, is 138 years old but was then only 31 years old and unrestored. Then, the background was disposed in distinct but linked quadrants (top-left; top-right; bottom right; bottom left). These were not so much naturalistic renderings of an actual space as subservient pictorial devices spotlighting the central bow-tight figure of a child trainee who, through balletic discipline and artistry, had assumed a commanding Velazquez-worthy sideways-on viewer-confronting presence.
To that expressive end Renoir had welded the dramatically contra-directional lower legs into unity by a pronounced dark shadow in the vertical triangular space they bounded. That shadow sprang also from the heel of the (right) weight-supporting foot backwards and upwards in space, thereby throwing the bottom edges of the trailed skirts into relief. This dark zone in the lower-right counterbalanced another in the upper-left, which had in turn emphasised and thrown into relief the front edge of the costume, withdrawing only to leave a lighter, again relieving, tone at the dancer’s dark hair. The progressive loss through restorations of those artful dispositions (as seen in Figs. 4 & 5) and the picture’s general descent towards an inchoate, arbitrary pictorial froth that increasingly resembles the underlying condition seen today in its own infra-red imaging (see Fig. 6), is heart-breaking. Renoir had here been a sculptor before he became a sculptor, playing off forms that asserted his picture plane with others that ran sharply away from or towards it (rather as Michelangelo had famously done in his crucifixion of Haman). Degas, who spoke of Renoir’s “sharpness of tones”, had chided himself for constructing his own drawings of standing dancers from the head down instead of from the feet up. Renoir had here given a masterclass in how to project a standing figure upwards from the floor. These things artists know and appreciate.
Compendious photographic evidence suggests that restorers (frequently working myopically through head-mounted magnifying eyepieces) have consistently confounded dirt or discoloured varnish with the shiftingly elusive dark grounds used by artists to set off light-toned figures. As seen in our post of June 1st, Klimt’s portrait of Serena Lederer (which was acquired by the Metropolitan Museum of Art, New York, in 1980) has suffered in just such a manner. In the same post we saw also how Renoir’s deployment of a dark background zone in the upper left quadrant of background and a secondary but counter-balancing dark zone in the lower right quadrant of his “Dance in the City” had also been undone by successive restorers.
By courtesy of the 1905 photograph of the dancer we can now see that by 1944 the picture’s decisive tonal orchestration had already been subverted (see Fig. 3 and caption at Fig. 6). By the time of the picture’s appearance at the 2012 Frick show of Renoir’s full-length portraits (which was reviewed in our post of June 1st), the original dark tones in the lower right quadrant had effectively disappeared, leaving two odd arbitrarily truncated dark attachments to the right heel (Fig. 5). Cumulatively, this painting has suffered needless artistic vandalism of which no one speaks. The fact that graphite underdrawing is now visible on the painting has been mentioned but without any hint of alarm or censure.
With Renoir’s “Baigneuse” of 1888, the earliest photograph in our own records (- donations to ArtWatch of old photographs or postcards are always most gratefully received) is that published in 1944 when the painting was 56 years old, as seen here in greyscale at Fig. 7 (left) and at Fig. 9. Six years later, by 1950, the painting had been radically transformed, as seen at Fig. 7 (right, in greyscale) and Fig. 8 (left, in colour). The differences that emerged between 1944 and 1950 were compounded by further changes between the picture’s 1950 state (seen in colour at Fig. 8, left) and its 2012 state (seen in colour at Fig. 8, right). However many times and by whomever this painting might have been “restored”, it is clear that the resulting interventions have profoundly altered its constructional and pictorial rationales. The total extent of the alterations that occurred between 1944 and 2012 are examined right in greyscale details in Figs. 11-18. The differences between the 1950 and 2012 states are examined in colour details at Figs. 19, 20 and 21.
By 1888 Renoir had visited Algiers and Italy, come to admire Cezanne as well as Delacroix, discovered Italian painting and read Cennino Cennini’s Treatise on Painting. He had just completed an intense series of classically inspired, Ingresque female nudes, culminating in that declared trial for decorative painting, the Philadelphia Museum’s great “Bathers” of 1887, by which date he held the nude to be one of the most “essential forms of art”.
Compared with Fantin-Latour’s palpable but fluidly allegorical figure at Fig. 10, Renoir’s “Baigneuse” has, in its 1944 state, a markedly more stolid, out-of-Courbet corporeality. For all its spirited brushwork and sparkling colour, plastically, it constitutes an essay in composure, stability and parallelism. The torso seemingly rests on its own base of compressed and spreading buttocks and thighs. The thighs, knees and lower legs are held together in a manner more primly archaic (Egyptian) than classical. Movement is confined to the bather’s right hand which dries the left side of the waist. This action has enlivening consequences. The upper torso is pulled round by the right arm and the head is turned leftwards and downwards as if to contemplate the drying action of the towel. The left arm is required to be held aloft to free the left side of the figure, and, flexing at the elbow as the left hand draws across the face, it first echoes the thighs but then curls gracefully, weightlessly away in space.
What, then, explains the differences between the picture’s previous and its present condition? In such cases it is always possible to play the “Sistine Chapel Ceiling Restoration Defence” and claim that in 1944 the then 56 years old picture was very dirty and that the removal of this dirt has liberated the forms and the colours of the painting to a hitherto unsuspected degree. But the pattern of relationships that is visible, even under dirt, should not change character during a cleaning. Rather, it should emerge enhanced, with the lights lighter and the darks darker – and all individual values holding their previous positions. This has not happened – the picture has got progressively lighter with successive cleanings instead of returning to its previously cleaned state. If it really had been left by Renoir in today’s state, how could the previous but now lost artistically constructive values ever have arisen? If left untouched for the next 56 years, would anyone expect the painting to return to its 1944 appearance with the stripes on the towel and the shading of the fingers regaining strength? Would a general shading and enhancement of forms once more helpfully tuck the left hand behind the head? How might dirt have drawn more clearly and repositioned the left shoulder? How might it have more emphatically shaded the right, distant side of the face?
If we consider the difference between the 1950 and 2012 colour plates (shown at Figs. 8, 19, 20 & 21), what might account for the loss of orange coloured modelling in the left cheek, and of individual brushstrokes depicting the hair? Is it possible to claim on the evidence of these photographs that there has been a build-up of dirt on the picture over the last 62 years?
When examining the bather’s face in close-up today, as shown at Fig. 21, can we have any confidence that the paint presently surviving in that section is just as it was when left by Renoir in 1888? What kind of brush or paint might he have used that would have resulted in the present fragmentary, seemingly abraded, scattering of orange paint that lies over the blue background between the hand, the face and the shoulder?
In the next post we examine the conservation fate of more than a score of Renoirs that have been loaned from the Sterling and Francine Clark Art Institute in Williamstown, Massachusetts to the Royal Academy. We shall see how Sterling Clark learned the hard way not to trust art experts on matters of condition in paintings when, having been assured that Domenico Ghirlandaio’s “Portrait of a Lady” had never been repainted, he bought it, only to discover, very shortly afterwards, a postcard of the painting showing it in an earlier and quite different state.
