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 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?

Misreading Visual Evidence ~ No 2: Michelangelo’s Sistine Chapel Ceiling
No single proof of a restoration-induced injury to a work of art could be clearer than the photograph shown here (Fig. 1) of a section of Michelangelo’s Sistine Chapel ceiling frescoes. It was taken after the last restoration and shows in its centre section a repair made in 1566 by the painter Domenico Carnevale when a section of Michelangelo’s fresco fell away during settlement of the building (see Fig. 2 diagram). Carnevale had re-plastered the loss and, while the plaster surface was still wet, faithfully painted it to match Michelangelo’s (then) surrounding colours and tones. The repair was a good one and for centuries it remained almost invisible (see Figs. 4, 5 & 6). Ever since the last restoration it has been glaringly evident that Carnevale’s painted section no longer matches what has survived of Michelangelo’s painting (see Fig. 7). As will be shown, on the evidence of these photographs, fair estimation can be made of the injuries inflicted upon Michelangelo’s frescoes during restoration.
The reason why the photographs testify to restoration injury is simple and elegant. Carnevale’s repair was made a fresco in “good” or buon fresco, which is to say, solely with pigments that were painted onto the still-wet plaster and, crucially, without any later additional painting on the surface of the fresco after it had dried. With this method, Carnevale matched the pictorial values of Michelangelo’s frescoes as they were then found, only half of a century after their completion. However, unlike Carnevale’s painting, where the pigments were locked into the lime plaster when it dried, Michelangelo’s own frescoes were completed a secco – that is to say, with much additional glue or size-based painting applied to the surface of the frescoes after they had dried. Against great evidence (see below), the Vatican’s restorers concluded that Michelangelo had painted entirely in buon fresco without a secco additions and, on that (unsound) decision, they contended that it would be perfectly safe to apply a recently developed oven cleaner-like thixotropic cocktail of cleaning agents (in two applications of three minutes duration each, each being washed off with copious amounts of water) that had been designed to strip polluted encrustations from marble buildings and that would most certainly strip all organic material – which in the event would include Michelangelo’s own glue-based painting – from the ceiling’s plaster surface.
Because Carnevale’s own painted repair was not so vulnerable we now see in the repaired (centre) section a better record of how Michelangelo’s own painting had appeared than exists in the surviving sections of Michelangelo’s painting. By properly reading the testimony of this photographic record, we can calculate the scale of loss that ensued when Michelangelo’s own a secco work on the surface of his frescoes was removed.
By that method, Michelangelo had painted shadows onto his figures after the plaster had dried. After the recent removal of those shadows a figure emerged (as seen right) with arms that were apparently depicted flatly and without tonal modulation in a single local colour/tone by Michelangelo on either side of a section by Carnevale where the forms of the arms were fully modelled by dramatic shading. Could that ever have been the case? Would Carnevale have been allowed to conduct a master-class demonstration to Michelangelo on how to render painted forms sculpturally? Those who still defend this restoration – as some British newspaper art critics do – might attempt to offer some credible explanation for this startling visual and plastic mismatch, which presently stands as the largest elephant in the art restoration room.
The crime against art that this restoration constituted was compounded by art historical apologists who claimed that the Michelangelo everyone for nearly five centuries had thought existed, had never existed, and that a new, true Michelangelo who, far from being “essentially a sculptor” was “one of the great colourists of Western Art”, had been uncovered by courtesy of a single cleaning. To justify this historically revisionist and artistically subverting “outcome”, apologists for the restoration were obliged to offer one of the most cockamamie art historical/technical accounts: namely, that what had “deceived” Michelangelo’s own contemporaries and everyone else for nearly five centuries had been nothing more than the effects of dirt and soot that had slowly and imperceptibly accumulated on the ceiling’s frescoes over the centuries.
This deceiving filthy material had, the artistically credulous are invited to accept, artfully arranged itself around Michelangelo’s flat, bright, “colouristic” designs so as to mimic the effects of the very sculptural preoccupations for which Michelangelo was already famed. In due course, it was further suggested, this artful dirt and soot had been set in glue by successive restorers, who, on one occasion, it is said, did so while standing on the top of thirty feet high step-ladders while brandishing glue-filled sponges tied to the end of thirty feet long poles. When the Vatican authorities were challenged on this account (by us) they had to admit that no proof existed of any glues ever having been applied by any restorers. What the Vatican authorities might also have admitted is that a further indisputable technical proof of Michelangelo’s authorship of the glue-painting on the fresco surface had emerged in the 19th century when the Vatican made its own moveable scaffold available to the British painter Charles Heath Wilson – and that this testimony was known to them. On examining the ceiling, Wilson had found that:
“…the frescoes are extensively retouched with size-colour…evidently by the hand of Michelangelo”.
Wilson could not only see this glue painting on the plaster surface, he could touch it:
“The colour readily melted on being touched with a wet finger and consisted of a finely ground black, mixed with a size…The shadows of the drapery have been boldy and solidly retouched with this size colour, as well as the shadows on the backgrounds. This is the case not only in the groups of the Prophets and the Sybils, but also in those of the Ancestors of Christ in the lunettes and the ornamental portions are retouched in the same way. The hair of the heads and beards of many of the figures are finished in size colour, whilst the shadows are also thus strengthened, other parts are glazed with the same material, and even portions of the fresco are passed over with the size, without any admixture of colour, precisely as the force of water colour drawings is increased with washes of gum…These retouchings, as usual with all the masters of the art at the time, constituted the finishing process or as Condivi expresses it, ‘l’ultima mano’.”
In addition to his expert (i.e. artist’s) testimony, Wilson offered two further material proofs of Michelangelo’s authorship that might otherwise have been expected to be considered clinching by today’s “scientific” restorers:
“They [the retouchings] were evidently done all at the same time and therefore when the [original] scaffold was in its place.”
“There can be no doubt that nearly all of this work is contemporary, and in one part only was there evidence of a later and incapable hand. The size colour has cracked as the plaster has cracked, but apart from this appearance of age, the retouchings have all the characteristics of original work.”
It is a matter of record that the ceiling cracked before any restorers went near it. If the size painting cracked with the plaster, it must have predated the cracking – and, therefore, also that of any restorer’s intervention. Or, to reverse the testimony: if the glue had been applied by restorers long after Michelangelo had painted the ceiling and long after the ceiling had cracked, as has been suggested, it would have run into the already extensive cracks – but it was not and it had not. We can thus be in no doubt that today’s restorers removed the final stages of Michelangelo’s own work; that the “New Michelangelo” they had “discovered” was nothing more than the mutilated remains of his original work that they had left on the ceiling; that no part of the ceiling had escaped the consequences of their labours.
The last restorers of Michelangelo’s ceiling frescoes seem not fully to have heeded the cautionary evidence of their predecessors’ mishaps. The warnings – both pictorial and documentary – were clear enough. We see in the photograph of the left hand of God from Michelangelo’s “The Separation of the Earth from the Waters” (Fig. 10) that there is today a great mismatch between the sleeve and the fragment of cuff that had been repaired by Carnivale. Engraved copies of the 18th and 19th centuries (see Figs. 8 & 9) suggest that losses of shading to God’s left arm preceded the latest restoration. Charles Heath Wilson, who complained of the ceiling’s filthy and neglected condition and believed that it would profit from cleaning, nonetheless warned in terms against any watery interventions. Not only had he found Michelangelo’s size-painting vulnerable to a wetted finger, he complained that parts of the ceiling had already “undoubtedly been injured by rude [restoration] hands, suggesting that glazing has been partially or entirely swept away” and that great restoration injuries had previously occurred when the ceiling had been “washed by labouring men with water in which a caustic has been mixed”. (For details of the recent water-based cleaning methods, see bottom right.) The consequences of water injuries had been set out by Wilson:
“Thus great brushes or sponges have been swept over the skies and backgrounds and have not only removed dirt in a coarse unequal way, but have eaten into the colours and destroyed them in a variety of places. The Face, shoulder and arms of the prophet Daniel, various parts of the bodies and limbs of the young men sitting over the cornice and other portions of the frescoes have been nearly obliterated by this savage proceeding. The Injury done is irremediable, for the surface of Michelangelo’s work has been swept away.”
