Another Restored Leonardo, Another Sponsored Celebration – Ferragamo at the Louvre…
The penny dropped last week in Paris: museum picture restoration is becoming a money-making machine in which the artistic sums may not necessarily add up. The Louvre’s restored Leonardo “Virgin and Child with St. Anne” re-appeared in a series of openings for a swish exhibition-of-celebration, “La Sainte Anne l’ultime chef-d’oeuvre de Léonardo de Vinci”, sponsored by the Italian fashion house Salvatore Ferragamo (whose 2012 fashion show is to be held within the Louvre). The official defences of the restoration are found in the exhibition literature and in a DVD film (“Leonardo de Vinci The Restoration of the Century”) celebrating “The spectacular operation, the likes of which occurs only once a century”. Although there may be a touch of “The Official” in the film, acknowledgement is certainly made of opposition to the course of the restoration that came from within the advisory committee itself. Jean-Pierre Cuzin, the former director of paintings at the Louvre, is seen to speak with great eloquence on the option of, essentially, leaving well enough alone. Reference is also made to wider opposition that was reported in what is described as “a virulent press campaign”. The organisation of the exhibition itself is seen to testify to the rapid growth of mutual support systems within the international museum community. At the same time, we can now better gauge the restoration’s artistic consequences and better appreciate why two eminent art authorities, Ségolène Bergeon Langle, the former director of conservation for the Louvre and France’s national museums, and Jean-Pierre Cuzin, resigned from the restoration’s international advisory committee.
As with the Credit Suisse sponsored exhibition “Leonardo da Vinci – Painter at the Court of Milan” which gathered £1.5bn worth of Leonardos in celebration of the National Gallery’s restored “Virgin of the Rocks” (see Figs. 17 & 18), this Ferragamo/Louvre exhibition has drawn masterpieces by Raphael, Michelangelo, Pontormo, Andrea del Sarto and others. The National Gallery (two of whose staff members served on the St. Anne restoration’s international advisory committee) loaned its hitherto unloanable Leonardo “Burlington House Cartoon” in a straight swap for the Louvre’s earlier loan of Leonardo’s original “Virgin of the Rocks” to the London Leonardo-fest. It would seem that in this international bonanza, one restored Leonardo begets another and each begets a plumply lucrative exhibition and catalogue. The current escalation in travel and restoration risks for works of art is terrifying.
The Louvre’s current exhibition is said by the curator, Vincent Delieuvin, to comprise “a science workshop”. But this “workshop” could not inform the treatment of the painting because it followed, not preceded, the restoration. Moreover, the exhibition itself imposed a guillotine on the restoration. Members of the international advisory committee who wished for more tests, for more consideration of vexing issues, felt thwarted by the Louvre’s need to finish the restoration in time for the arrival of the stupendous borrowed treasures. The cumulative assembled testimony of the exhibition’s many borrowed copies and derivatives of the “St. Anne” might well have been instructive, but, not having been seen, it finds no reflection in the restored Leonardo which artistically has pulled away from its own off-spring (see Figs. 13-16). Delieuvin’s reported twin claims that the restoration “is a true resurrection of the ‘St. Anne’” and that “The painting has recovered a depth and a relief almost like sculpture, with an intense palette of lapis lazuli blue, lacquer red, grays and vibrant browns”, seem both rather tastelessly hyperbolic and at variance with visual evidence (- see right).
Certain structural stresses in the over-heating art economy have become visible. At the exhibition’s epicentre the “Burlington House Cartoon” and the “St. Anne” (for which picture the drawing was a study), have been brought together side by side in a spectacular but counter-productive coup de théâtre (see Figs. 13 & 14). The drawn study, now discoloured but sombrely potent in a magnificently worthy black frame, conjures a breath-taking orchestration of monumentally poetic forms, forms that rightly have been seen to rival the pedimental female groupings of the Parthenon sculptures. Since the Second World War there has been no drawing in existence to rival this fragile and brittle manifestation of the grandeur of Leonardo’s thoughts. (If lost – and in recent years lorries have been burnt-out in the Channel Tunnel and a ferry and its lorry cargo was lost in the Channel – no insurance money or state indemnity could acquire another of its kind.) In contrast, the restoration-weakened “St. Anne”, with its now arbitrarily floating, obtrusively abstract and glitzy lapis lazuli blue drapery, has departed from its formerly-realised self, as the adjacent cartoon and the exhibition’s many derivative pictures mutely testify. To see strong colours subsumed within tight sculpturally integrated groups, we must now look to derivatives of Leonardo rather than to their progenitor (see Figs. 15 & 16).
As if to inoculate the exhibition viewer against this back-firing juxtaposition, the wall immediately opposite the cartoon and the “St. Anne” carries a portentous notice headed “A fundamental restoration”:
“A fundamental restoration of Leonardo da Vinci’s St Anne was initially envisaged in the 1990s when a few quite conclusive cleaning tests were carried out.
“The picture’s dull appearance, its hues discoloured and distorted by numerous repaintings of the sky and the Virgin Mary’s blue mantle, demanded the intervention that finally began in 2009. Minute bulges, very probably caused by the stress exerted on the picture layer by the hardening of old restoration varnishes rendered the restoration inevitable.
“Preceded by an exceptional series of preliminary examinations and scientific imagery analyses carried out by the laboratories at the Centre de recherche et de restauration des musées de France (C2RMF) and generously financed by Mr Barry Lam, the restoration itself began late in 2010. The restorer, Cinzia Pasquali, was chosen following an invitation to tender and worked for more than a year at the C2RMF in the painting workshop in the Pavillon de Flore.
“The restoration comprised two principle problems: the removal of the discordant repaintings, some resulting from very ancient and thick accumulations of retouches, the thinning of restoration varnishes oxidised and deteriorated by too many partial cleanings, the moving of excess varnish from one area to another using solvents, retouches and refixings down the centuries throughout its long history, the picture had obviously been devarnished and revarnished many times but fortunately the picture layer had been sufficient robust to resist this. The extremely irregular and oxidised state of the surviving varnishes distorted all the tints and, by a well-known physical effect, ‘decolourised’ and yellowed the original hues.
“The gradual thinning of these varnishes to a uniform level was therefore the restoration’s major challenge. During this process, resin analyses and measurements of varnish thickness, conducted by new techniques developed at the C2RMF enabled an extremely precise approach to the thinning, which had to be undertaken delicately, both to preserve a degree of patina on the picture and protect the painting itself from any contact with the solvents used. This extremely gentle cleaning process revealed a painting in vivid colours and resuscitated the splendid lapis lazuli blues and refined violet reds and crimson kermes gum lacquer.”
In this classic museum PR conflation of aesthetic and conservation “needs”, we are variously told that aesthetic changes had been necessary on urgent conservation grounds; that the restoration was “envisaged” some time ago and that this aspiration had been reinforced by the picture itself whose dull appearance “demanded” a restoration. Meeting this demand from the inanimate is said to have been made “inevitable” by a mysterious conservation ailment in the form of “minute bulges” which “very probably” were being caused by the varnish itself.
“Very probably” is a distinctly weasel-phrase and seemed the more so because Ségolène Bergeon Langle had very recently pointed out that the minute manifestations were confined to a single board (which had been badly cut when first made) within the panel, and therefore could not have derived from overall varnishes which some were itching to remove. This analysis of the actual cause was accepted on the DVD film where it was claimed that the restoration had had to proceed because of “lifting due to contraction of the wooden panel”. That raised the larger restoration question: if the varnish was not causing the lifting, was there any conservation reason for removing it at all? A frankly negative admission on that point would, of course, have greatly strengthened the position of the “moderates” on the advisory committee who were, under any circumstances, urging restraint and caution. We now hear that not only is it admitted that the liftings of paint were indeed caused by this plank, but also that they had easily been repaired locally. In hope of preventing future liftings, the panel painting is to be encased in framing that will incorporate a suitable micro-climate designed to stabilise the offending wood. On the face of it, this is good news but, in today’s museum practice, a risk removed often seems to make space for another to be incurred. And, sure enough, we also hear it is now thought that, with the provision of its own micro-climate, this great picture can be regarded as safely peripatetic – and that as such it is to be despatched in the first instance to an annexe of the Louvre at Lens, in northern France. But then where next – Tokyo? Dubai? California? And on what tariff? Perhaps in addition to adding this “restoration of the century” to our list of cleanings sold on misleading conservation-necessity prospectuses, the picture should also be put on our Now At Grave Risk of Travel Injuries category? We trust that the Louvre authorities will amend their misleading wall notice on the restoration.
The material on the picture’s surface is said to have been the accumulated product of many and various previous restorations (some with caustic substances), throughout all of which Leonardo’s original paint had suffered no injury. What chance, therefore, could the last restoration’s highly advanced, “extremely precise” techniques have produced anything other than an “extremely gentle” cleaning? Well, first of all, the proof of the pudding is in the appraising of the result – see right. Second, it is never wise to take restorers’ own prognoses at face value. Errors can occur at any point of the restoration process. The suggestion that a uniform layer of varnish had been left in place might surprise members of the international advisory committee who had been under the impression that varying thicknesses of varnish would be left in place according to specific needs for caution (as with the especially vulnerable face of “St. Anne” – see right).
Further, questions arise in terms of conservation methodological practice. In restorations, paintings are stripped down and then reassembled by repainting. Where, then, are the detailed photographic sequences showing the painting before cleaning; after cleaning but before retouching; and, after cleaning and retouching? Without such hard visual documents the path of the restoration cannot be retraced. It was only when the National Gallery kindly provided such photographs that we were able to identify an unacknowledged change that had been made to the angel’s mouth in the London “Virgin of the Rocks” (see comments at Figs. 17 & 18).
In the two versions of the Louvre exhibition catalogue (one of 52 pages at 8 Euros and one of 448 pages at 45 Euros) there are not even any facing images showing the picture before and after restoration. Such a pairing is found in the (excellent) Beaux Arts special “Léonard de Vinci – Les secrets d’un génie” at 6.90 Euros (a similar comparison is shown here in Figs. 14 & 16). There is also a helpful before and after restoration record of the National Gallery’s “Virgin of the Rocks” (see Figs. 17 & 18).
The Louvre and the National Gallery leonardo restorations share a common methodological feature: in both cases it is said that old varnishes were thinned but not completely removed. This claim creates a conundrum because in both cases changes have taken place which seem inexplicable in terms of a mere thinning of varnish. When explanations are sought or when appraisals are attempted, restoration authorities sometimes take fright, retreating behind claims that theirs is a highly specialised technical field whose mysteries are simply unfathomable to outsiders. Restorers themselves often don the proverbial doctors’ white coat and claim to have acted on not aesthetic grounds at all but on (quasi-) medical ones. For the “St. Anne” restorer, Cinzia Pasquali, this restoration was not made for aesthetic reasons. Instead: “This was about caring for a sick patient. From the conservation point of view we had to intervene, primarily to address a cracking of the varnish that could leave the paint exposed to damage.” Well, we now know that in this particular case the patient was not as sick as had been thought. But more importantly, we should remember at all times that works of art are made by people to be looked at by people. They are not created as laboratory specimens. Artists work with materials so as to produce values and relationships between values. No scientific test can analyse a value, let alone an inter-related group of values. To its maker, the professional test of a work of art is how it looks – the painter stops working precisely when the picture looks right.
In the realm of art and away from corporately funded museum politics, the ultimate test of a restoration is also how it looks – but that is to say, not how it strikes the passing viewer (who may or may not be thrilled by solvent-brightened colours) but how it looks now as compared with how it looked previously; how it looked not just immediately prior to restoration but in its successively recorded history; and, most especially, how it looked the last time it was cleaned. If picture cleanings did no harm, if they were as simple and non-destructive as cleaning a window, each restored work would return to its appearance when last cleaned, and there would be no surprises, “discoveries”, “revelations”, “restorations of the century” – or controversies. While no one ever berates a window cleaner for ruining the views, restorations irreversibly change a picture’s “view” on to the world. Restoration is a one-way street that runs away from history, away from the original work.
All cleaning controversies turn on the extent to which pictures suffer during restoration. Even among those who authorise restorations, some concede that there are losses as well as gains and frankly admit to seeking the best trade-off between improved legibility and pictorial injury. Defensive restorers insist that pictures cannot be harmed by their own “advanced”, “gentle” and “scientifically underpinned” methods. Making a fetish of the “safety” and the “science” of restoration methods attempts to shelve restorers responsibility to identify and account for all material and aesthetic changes. Given that all restorers’ methods cannot be superior, none should be held beyond question. With the physical alteration of art, aesthetic appraisal is essential to scholarship and art’s protection. In appraising restorations, the comparison of like with like is of the essence.
In visual arts, appraisals are necessarily made by visual comparisons. Pictures are made by eye, hand and mind, to be viewed by eye and mind. Because each cleaning destroys the earlier state, comparisons can only be made between pre and post-restoration photographs. While straightforward cleaning might always be expected to achieve a greater vivacity of pictorial effect, it should never be made at the expense of the pictorial relationships, patterns, or gradations made in the service of modelling, that can be seen to reside in the uncleaned work. If the relationships can be seen it is because they are there – whatever chemical analyses might suggest to the contrary. The aesthetic production of pictorial values by artists is the proper science of art. Unfortunately, in such terms, the values that were formerly evident in this great picture seem not to have fared well in this last cleaning.

Black is a Colour
We reported in an early Journal that Anna Somers Cocks, when editor of The Art Newspaper, had observed that Frans Hals employed as many as six tones of black and that these were “too often deadened by bad cleaning”. This prompted a response from a painter colleague.
Iain Walker wrote:
Anna Somers Cocks’ observation that Frans Hals painted with up to six tones of black reminded me of another appraisal made some years ago when Hals was being shown at the Royal Academy. An eminent art critic noted in his review of the exhibition that Vincent van Gogh had claimed to have counted no fewer than 28 different blacks in a Hals painting. The observation, the critic accepted, may have indicated Vincent’s preoccupation with the picture but it could not have been so because research had revealed that at that date there were only six blacks in production. Many readers may have concluded that poor Vincent had got it wrong again, and that this was a critic who did his homework.
At the time of this review, a project exploring the nature of black and the assumptions we have of it, was being conducted with the first year students at the City and Guilds of London Art School in Kennington. To this end, one side of the studio had been painted black throughout and filled with black objects and materials: black cottons, velvets and silks, as well as a numerous household objects that were painted or sprayed with matt or gloss paint. Coal and soot were also used.
The task given to the students was to make a perceptually accurate painting of a section of the studio without using any black paints. They met this requirement by mixing their own blacks from the colours contained in their paint kits. It was pointed out that Francis Bacon often produced a black by mixing sap green with alizarin crimson. The students also made use of Prussian blue, cobalt, burnt umber, violet etc. Their studies swiftly established that it was entirely possible to make an optically accurate transcription of a black set-up containing many black objects without ever having recourse to any commercially available black paint.
In painting, all colours and tones are relative. Margaret Meade cites the Eskimos as having 17 words for white. When confronting an all black set-up, it soon becomes apparent that there are greenish blacks, reddish blacks, bluish blacks and so forth. Theoretically, there may be a black which absorbs all incident radiation but even a material as black as soot apparently reflects 3% of incident light. Couple this fact with the effect of “simultaneous contrast” and it is hardly surprising that most painters think of black – and white – as colours in their own right and not just as means of creating a tonal range in a painting, as there other ways to do this.
I recall the above as a demonstration of how well-meaning academic research, although possibly correct in one way, can also be misleading and harmful when applied to painterly practice.

The Perpetual Restoration of Leonardo’s Last Supper, Part 2: A traumatic production of “a different Leonardo”
The unhappy $8m Olivetti-sponsored restoration of Leonardo’s Last Supper began in 1977 with a repair of small flakes of detaching paint. It morphed, on very grand institutional technical advice, into a promised liberation of all of Leonardo’s surviving original paintwork. It ended after twenty-two years amidst widespread recriminations and as a distinctly mongrel work showing alarmingly little original paint and very much alien “compensatory” and “reintegrating” new paint.
Prospective major restorations are often presented as elegant technical answers to some urgent conservation necessity the resolution of which promises magnificent artistic gains. In reality, the interface between technical intervention and artistic outcomes constitutes art restoration’s fault-line and does so in a field that is notoriously subject to the law of unanticipated consequences. One of the commonest surprises is how greatly the coherence of a work had depended on earlier restoration repairs that were removed on the grounds of being alien impurities. Like Humpty Dumpty, radically stripped works often prove to be wrecks that have to put back together again and many a restorer discovers – too late – that it is easier to take to pieces than to reassemble [see Endnote 1]. The resulting changes made during restorations are often presented as “discoveries”, “recoveries” or “recuperations” when on close examination they prove to have been plain errors. One such unwarranted, unsupported, insupportable case is shown here.
Towards the end, the restorer, Pinin Brambilla Barcilon, expressed the hope (Art News March 1995) that her restoration might be the last because: “The less you restore a work of art, the better its chances of survival. Each time you touch a work, it suffers a trauma, no matter how carefully you operate.” In November 1998 the Art Newspaper reported that when Mrs Brambilla was restoring a crucifixion on the wall opposite the Last Supper in 1978, she noticed that “fragments of painting were peeling off Leonardo’s work before her eyes.” The Guardian of July 21 1997 reported she had noticed “bits of painting falling from the Last Supper” and that after experts from Italy’s central institute for restoration in Rome (Istituto Centrale di Restauro) had been called in “the decision to restore the painting was swiftly taken”. Too swiftly, many Italian experts believed.
Although conservation necessities are sometimes exaggerated [see Endnote 2], with paint losses, determining the extent, cause, and remedy must always be the top priority – the equivalent of fixing a building’s leaking roof. As seen in Part 1, when the Last Supper was disintegrating to the touch after the Second World War, the then restorer, Mauro Pelliccioli, fixed the problem by embedding the paint in litres of shellac. He also won some critical praise for uncovering most of Leonardo’s own surviving paint from restorers’ over-paint. Crucially, however, he tackled the disintegrating paint first (during 1947-49). Only when the shellac was settled and the paint completely secure did he begin scraping off restorers’ repainting (during 1952-54). In this most recent restoration, despite the problem of paint detachment, work began with an intended systematic removal of the remaining repaints.
Effectively, in the last restoration the authorities undertook an all-or-nothing gamble with a masterpiece. Against the certainty that shedding the old would be disruptive of the familiar and the still-surviving, they bet that the recovery of some more fragmentary, talismanic relics of Leonardo’s paintwork would outweigh the scale of accompanying losses and newly exposed bare wall. This presumptuous naivety was to prove disastrously wrong-headed. First, as scientific tests of paint fragments (published in Studies in Conservation, August 1979) were to warn, the distinction between original paint and later restorers’ overpaint was not at all easy to establish: “the dividing line is much less clear cut”. (This was hardly surprising given the work’s earlier exposure to corrosive cleaning agents and heated metal rollers.) Second, Pelliccioli had already uncovered most (two thirds, he believed) of what was taken to be Leonardo’s surviving paint. While there was not all that much more to recover, there was, artistically, still very much to lose. Pelliccioli had left repaints in place precisely where they covered only bare wall – which is to say, where they held the image together.
The paradoxical consequence of this pursuit of original material was that the old ill-preserved yet somehow-maintained “theatrical” illusion that Leonardo had originally created was greatly undermined. One narrow specialised purist concern for what was “original” and “authentic” material was set against another larger more elusive aesthetic/artistic concern for what had been intended; for what was yet struggling to survive. Achieving the liberation of fragmentary and injured archaeological material imperfectly adhering to a damaged moisture-prone vertical surface came at the cost of eliminating all that had maintained and prolonged Leonardo’s decaying but originally mesmerising artistic illusion incorporated into the space and fabric of a large room. (Kenneth Clark had spoken fondly of “these ghostly stains upon the wall”.) The work was remorselessly stripped down to the sum total of all previously accumulated injuries in order that the resulting wreck might then be put back into some presentable aesthetic form more suited to today’s tastes. The ideological/art historical rationale offered for this purgative exercise was that every age has the right to make its own Leonardo…that the Leonardos that had come down to us from the past were somehow deficient, obsolete, culturally-contaminated; that we now simply know better. The preposterous nature and Futurist flavour of this relativist conceit (“Every previous generation has erred, we, standing outside of history – or at its end – will now get things right”) might have been held self-evident. Leo Steinberg, evidently unsettled by this recent spasm of historical/aesthetic cleansing, quoted Jonathan Swift: “Last week I saw a woman flayed, and you will hardly believe how much it altered her person for the worse.” (“Leonardo’s Incessant Last Supper”, 2001.)
The purist shedding of earlier repaints regardless of their antiquity and artistic functions, necessarily guaranteed that Leonardo’s work would be “altered considerably”, as Carlo Bertelli, the then director of the restoration, acknowledged in the catalogue to the 1983 Washington National Gallery of Art exhibition of Leonardo’s studies for the Last Supper. A later defender of the restoration, Giovanni Romano, not only applauded the creation of “a different Leonardo” during “a great restoration” (Il Giornale dell’arte, April 1999) but fawningly added that he would be “satisfied with a restoration of this sort every year.” Throughout this era of vaultingly high ambition, the restoration community needed the biggest possible “sell”: nothing less than a “New Michelangelo” was said to have emerged during the Sistine Chapel ceiling restoration. It became a commonplace that revolutionary restoration “discoveries” required the very “rewriting of art history”.
There is no mystery about how the latest calamity came about. In the 1983 catalogue, the Washington National Gallery curator, David Allan Brown, duly relayed the twin official reasons for the restoration: that the paint (which, under a microscope, resembled “the scaly skin of a reptile” ) had not remained secure; and, that Pelliccioli had not removed all earlier repaints. The repaints had to come off because they were now “threatening the stability of the original colour.” Not explained, was how this was so, or how much original paint had been left by Pelliccioli. In the July 2 1995 New York Times, Bertelli recalled having been “certain that there was enough beneath the additions to warrant this restoration”. He added that “Mrs Brambilla and I had examined the surface with a microscope, and we were surprised to see how much of Leonardo’s original work remained”.
In 1983 Allan Brown noted that “The expectation that a considerable portion of the original might survive [had given] a strong impetus to the decision in the late 1970s by the Superintendency of Fine Arts for Lombardy (at that time directed by Franco Russoli) in consultation with the Istituto Centrale di Restauro, to take up again the unfinished work of cleaning the picture.” This would suggest that so strong was the desire to revive and complete Pelliccioli’s unfinished aesthetic programme that the operation was begun even as the technical solution which had originally made that aesthetic objective possible was said to be failing. Whatever gains might have been hoped for or anticipated, by May 1998, Bertelli admitted (in Art News) that “Now we can see only a few square feet [of original Leonardo paint] but they are by the master” and, on a Channel 4 documentary that year (“The Lost Supper”), he characterised Leonardo’s mural as a “ruin” (“una rovina” ). In the November 1998 Art Newspaper Brambilla said, self-contradictorily, that the repaint had had to be removed out of fear that condensation might become trapped between “the artist’s original paint and the successive layers of paint”, and, that constant environmental conservation measures would henceforth be necessary because “the layers of repainting are no longer protecting the original paint.”
Which was the case? If the repaint was protecting the Leonardo paint, what had been causing the original detachments? Given that the 1979 tests mentioned above had established that it was not always possible – even under ideal laboratory conditions – to “decide exactly on the dividing line – both for areas and for layers – between what remains of the original and materials pertaining to later interventions”, how great could the risk have been of moisture insinuating itself between the original and the subsequent paint layers? On whatever technical premises it rested, when the restoration proper began on the better preserved right-hand side of the mural, the attempted removal of all previous restorers’ repaints and consolidations of paint, inevitably constituted a prolonged and sustained assault on the mural’s fabric – as Brambilla herself candidly described in the March 1995 Art News:
“Here we have a surface that is completely ruined, disintegrated into tiny scales of colour that are falling off the wall. We have to clean each one of these scales six or seven times with a scalpel, working under a microscope…Here I can clean an area one day and still not be finished, because when the solvent dries it brings out more grime from beneath the surface. I often have to clean the same place a second time, or even a third or a fourth. The top section of the painting is impregnated with glue. The middle is filled with wax. There are six different kinds of plaster and several varnishes lacquers and gums. What worked on the top section doesn’t work in the middle. And what worked in the middle won’t work on the bottom. It’s enough to make a person want to shoot herself.”
Could Pelliccioli’s already failing shellac have survived these repeated traumatic assaults with solvents and scalpels on all the glues, waxes, lacquers and gums within the paint-film? Had some new superior quick-acting consolidant been identified or manufactured? What were the structural consequences of this apparent removal of every atom of previous consolidations of the paint? Brambilla has said of the detaching paint “To re-adhere the fragments we used wax-free shellac in alcohol, the same adhesive as Pelliccioli applied during his intervention of 1947″. So, in other words, just some more of the same. If Brambilla’s best English wax-free shellac lasts no longer than Pelliccioli’s, we might expect another restoration within twenty years or so.
One thing is clear: the technical underpinning of the restoration, and the swiftness with which its unquestionably radically transforming methodology was applied, were both challenged by Italian experts. On July 2 1995 the New York Times reported that Mirella Simonetti, a Bologna-based restorer, protested: “There was never any doubt in their minds. They decided how to proceed without even conducting the proper analyses to determine how much of the original painting remained. They didn’t even submit their findings to an international committee of experts.” The Florence-based diagnostician, Maurizio Seracini, who had been called to examine the Last Supper after the restoration began, complained: “I think that Mrs Brambilla has worked in good faith. But you don’t decide to restore a masterpiece like the ‘Last Supper’ on the basis of what you see under a microscope. It’s simply irresponsible.” Seracini added “I myself have not seen any definitive scientific proof that restoration was really needed.”
That the authorities had not known how much original Leonardo paint might survive had been tacitly acknowledged as early as 1983, when, with the restoration one third completed, David Allan Brown could speak only in relative terms: “By comparison with other, well-preserved murals of the time, Leonardo’s detailed execution is almost entirely lost.” Even when the restoration was eventually finished (or halted) there was no agreement among the protagonists themselves on how much had survived. Carlo Bertelli, the director of the Brera Art Gallery in Milan, who effectively initiated the restoration, put the figure at 20%. Pietro Marani, the prolific Leonardo scholar who advised Brambilla from 1985 and became co-director of the restoration in 1993, once said that “no more than 50%” survived and later more ambiguously claimed that 90% had survived “in parts”. Giuseppe Basile (later the director of the restoration of Giotto’s Arena Chapel frescoes) put it at “about half”. Giorgio Bonsanti, the director of the Florence-based laboratory Opificio delle Pietre Dure, put it at “possibly 20%”. Giovanni Urbani, the director of the Istituto Centrale di Restauro between 1973-83, and the director of the Brancacci Chapel restoration, thought 25% had survived.
In 1989 a Milan town councillor, Maria Bonatti, brought an (unsuccessful) action against the restorer for accelerating the mural’s decay – a charge also made by the painter, essayist and paint materials expert Mario Donizetti, who held that it would “disintegrate more rapidly than before.” Ten years before the restoration ended, in November 1989 the Art Newspaper reported “Over the years work has been stopped repeatedly, sometimes following changes at the helm of the Milanese Soprintendenza and the Instituto in Rome, other times simply to allow the whole project to be reconsidered.” Eventually the proceedings quickened dramatically. In his 2001 book, Leo Steinberg recalled encountering the restorer and three young assistants in 1998 “all huddling at lower left scraping away”. On the cleared wall, “more filling was needed – and it had to be done fast (a deadline had been imposed from on high), so that this must-see tourist attraction would show decent finish to the daily sightseers.”
In 1983 Bertelli had said in National Geographic that Brambilla was taking a week to clean an area the size of a postage stamp. He quoted her professional plaint: “It’s difficult. The work is hard and tiring. It creates much physical tension bending over the microscope. After a few hours my eyes grow blurry. I may come every day for months. Then I must take an extended break. There is also the psychological tension. All the eyes of the world that know Leonardo are watching what I do. Some nights I do not sleep.” The pressure intensified as the restorer inched her way towards the central figure of Christ. In April 1998 the Art Newspaper reported that “Hundreds of tourists (mostly Japanese) last month lined up…to visit Leonardo’s Last Supper. The painting was back on view after having been closed for two months to allow restorers to work on the faces of Christ and the apostles.” That report evidently escaped the attention of the National Gallery’s then director, Neil MacGregor, who wrote in his 2000 BBC book “Seeing Salvation”:
“When the latest restoration was unveiled in 1999, all hell broke loose, and the admirably scrupulous restorer in charge was vilified in much of the world’s press…Among the wilder accusations, fears were expressed that the face of Christ had been altered. Happily these proved to be groundless.”
That the unveiling was badly received is beyond dispute, but if vilification was in evidence it was aimed by defenders of the restoration at their critics (see right). The extent to which the face of Christ was altered, and the evolving means by which the restorer came to impose her own distinctive, ahistorical, arguably arbitrary aesthetic reading on the unprecedentedly vast, fully-exposed areas of paint loss in a quest to “bring it back to its original colors and composition”, will be examined in Part 3. Here (right) we examine a single unwarranted change that was made to the design of drapery on Christ’s right arm and then presented as a restoration recovery.

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

Shedding archival records at the Tate and the Victoria and Albert Museum
A disturbing account in the Guardian of abuses of archival records within the museum world (“Tate’s national photographic archive ‘rescued from a skip’ after internal tipoff”, 24 February 2012 ) disclosed how the Paul Mellon Centre for Studies in British Art, received a call from a Tate employee who said “you might like the curatorial photo archive because we’re about to throw it on to a skip” (- or, in American usage, throw it into a dumpster). Shocking as this report was, it came as no surprise to us because in recent years the Tate has shown a notoriously cavalier way with its artistic holdings and its archival material (see right). More surprising was the Guardian’s revelation that an archive of black and white photographs of almost every item held at the Victoria and Albert Museum and grouped by subject, had also been dumped by the curator in charge.
This dual elimination of black and white photographs echoes the destruction of old black and white television programmes that routinely took place at the BBC until 1978. A further destruction of archival property within British cultural bodies in recent years included that of newspaper collections held by the British Library. Sometimes a justification offered for archival vandalism is that essential “content” has been preserved by transfer to other media. The speciousness of such claims and the frequent destructiveness of such practices were searingly established in Nicholson Baker’s 2001 book “Double Fold: Libraries and the Assault on Paper”.
Following our reported comments in the Guardian article, we received a note of sympathy and an invitation to read the “Florence Declaration” from the director of the Photographic Library of the Kunsthistorisches Institut Florenz (the Max-Plank Institut), Costanza Caraffa. We are indebted: it seems that there is a wider threat to photo archives. The Florence Declaration is a call for the integration within photo archives and libraries of photographs in both analogue format and digital format. Their dual preservation is rightly taken as being essential to preserve the photographic heritage for future studies.
The Florence institute’s own photo library was founded in 1897 and today comprises more than 600,000 photographs of Italian art from late antiquity to the modern era. Like many photo libraries, the institute has recently engaged in transferring photographic images to the new digital media to aid electronic cataloguing and greater accessibility. There can be no quarrel with such exercises, but, paradoxically, by virtue of the editorial decisions that are inherent in any major transfer of material to new systems of storage and dissemination, the Institute has become the more conscious of the unique and irreplaceable nature of its general physical historic compilation; of the value of its illuminating bequeathed collections-within-the-collection; and, of the unique testimonial potency of its individual “hard copy” historic photographs. (Needless to say, this combination of visual acuity and heightened sense of patrimonial responsibility is one with which ArtWatch is in great sympathy.)
For our own rather specialised primary purposes the value of photographs lies not so much in their individual intrinsic qualities, as in their relationships to other, earlier or later photographs. The accumulated sequences of images (of paintings, drawings, prints, architecture, sculpture, metalwork, illuminated manuscripts, stained glass, wall paintings and textiles) held in the Courtauld Institute’s Witt and Conway photo libraries, and the photographs of paintings held in the National Gallery’s curatorial and conservation dossiers, greatly facilitate the identification and demonstration of injuries to works of art through restoration “treatments” (see right, Fig. 4).
The great value of photographic collections is, however, multifarious not singular. For some researchers, the self-same images might assist in making specific attributions of authorship, or in establishing chronological relationships within an oeuvre or period. For others still, the images can inform more general scholarly, thematic, historical, artistic or even sociological studies. In truth, all such focussed collections facilitate and trigger infinite lines of inquiry and speculation – and their benefits can neither be quantified nor anticipated in advance. Digitalised versions of photo collections – immensely useful as they are – cannot replicate or replace the ultimate benefits of “hands-on” studies of hard copy photographs, each of which is a physically and historically unique record made at a certain time, in a particular way, of a certain object, under a particular lighting condition. The ability to compare, juxtapose and read such various, culturally-expressive living historical records, in real space and real light, one against another, freely and without the physical and visual fatigue that attends a prolonged relationship with a fixed electronic screen (see right), is a methodological luxury and necessity. A photograph is a thing; a digital version is a virtual simulacrum of a thing. Although it is technically possible to track every manipulation of a digital photograph’s raw data, in practice, a photograph-as-object is more trustworthy, carries its traits and its history about its person, as it were. A most moving evocation of the multiplicity of uses within hard-copy photo collections – and of their great vulnerability in a philistine, cost-cutting world – was brilliantly captured by Stephen Poliakoff in his 1999 award-winning television drama, “Shooting the Past”.
We have long suspected that the inescapably destructive impulse of restorers constantly to undo and redo the material fabric and the artistic character of works of art through restoration/conservation “treatments” is a manifestation of a wider, history-hating cultural pathology; a narcissistic and hubristic desire of succeeding generations to remake history in their own image rather than to learn from it. The evidently assumed similar right of curators to undo and discard the historic record itself – even when held it is held in public trust by supposedly dedicated, culturally and fiscally privileged institutions like the Tate and the Victorian and Albert Museum – and even though that record possesses the power to hold to account as well as to illuminate, is a dangerous new, hitherto unimaginable, cultural low.

The Perpetual Restoration of Leonardo’s ‘Last Supper’ – Part 1: The Law of Diminishing Returns
The restoration of Leonardo’s “Last Supper” (1977 -1999) was defended last month at the National Gallery symposium on the artist’s methods and influence, by Pietro Marani, the Leonardo scholar who co-directed the restoration from 1993 onwards. When we pointed out that while the previous restoration had been praised for recovering all of Leonardo’s authentic paintwork, the last restoration had in fact introduced vast areas of new painting, Marani held that restorers and curators may impose their own generation’s values and interpretations. Appeals to the authority of one generation cuts little ice given how happy each proves to be to undo and redo its predecessor’s work – and, besides, given that on past form we are already half way along to the next generation’s “Last Supper” restoration, the one presently being defended is already approaching its own “sell-by date”.
In its early days, the last restoration was presented as a near miraculous liberation of the original and entirely unadulterated handiwork of Leonardo da Vinci, when that claim, far from being a novel one of its day, was, as mentioned, a re-run. In 1958, John Canaday, the art editor and art critic of the New York Times, reported how, following the war-time bombing of the refectory housing the mural in Milan:
“When the sandbags were removed…the ‘Last Supper’ was in such pitiful condition that historians were ready to list it as a war casualty. But since then the picture has been gone over as definitively as the combination of exhaustive scholarship and high technical skill make it possible to preserve once and for all whatever is discoverable of the original work. The results are better than anyone expected, although the painting still suggests a ghost at best or, at worst, an embalmed relic…”
Taking their cues from restorers, commentators often dismiss past treatments and celebrate more recent scientifically under-pinned “definitive”, “once and for all” and “miraculous” ones. (Just this week, a Rubens – his “Cain Slaying Abel” – that has been restored at the Courtauld Gallery with funding by the Bank of America, is said in a press release to have stabilized the painting for nothing less than “the next one hundred years”.) The “Last Supper” rescue operation took place in two stages in 1947-49 and 1952-54. In the first, the restorer Mauro Pelliccioli (see Fig. 1) supervised by a former Superintendent of Fine Arts in Milan, Fernanda Wittgens, anchored the disintegrating paint with shellac. As Wittgens’ wrote in the Christmas 1954 issue of Art News, “This was not ordinary shellac, of course, but an absolutely colourless one recently produced in England by a chemical process that removes all wax.” With this shellac, Wittgens went on, Pelliccioli performed his wonders:
“…it produced the greatest miracle of the entire restoration. The reattachment of the painted surface was achieved to perfection, and the colours acquired a new consistency as though they had been actually rejuvenated by the shellac that made them adhere to the wall…Mauro Pelliccioli, by doing away with all glues soluble in water, had permanently eliminated the danger of mould: he had at last hit upon a tremendously strong, transparent adhesive impervious to humidity.”
When the shellac was settled, Pelliccioli began scraping off the repaints of earlier restorers. Bernard Berenson visited the scaffold and later reported how, with no more than a penknife, a razor and a drop of turpentine, Pelliccioli had “touched bottom” by removing the “multiple restorations of centuries” and allowing the paint of Leonardo, “deteriorated by the centuries but no longer deturpated by incompetent hands” to be seen once more. In his diary note on October 21st 1953 Berenson said that Pellicciolli had known precisely “where to scrape” – a point echoed and amplified in H. H. Pars’ 1957 “Pictures in Peril”:
“Pelliccioli was able to distinguish those parts of the painting where nothing of the original painting was left, and those parts where overpainting and restoration concealed Leonardo’s own brilliant colours. Step by step these were revealed in the now firmly-fixed painting until we are now able to see Leonardo’s ‘Last Supper’ in better preservation than for many generations, deteriorated through the centuries it is true, but no longer marked and deformed by incompetent hands.”
Thus, to everyone’s satisfaction, the work had been physically rescued and what authentic Leonardo paintwork could be exposed to view had been liberated. Earlier restorers’ repainting was left in place only where it covered bare wall. Just twenty-one years later in 1975, Pinin Brambilla Barcilon, a former student of Pelliccioli’s, reported that fragments of paint were falling off the mural. Two years later, following tests, she began re-securing those parts of the paintwork that were becoming detached. Her minimal and straightforwardly necessary conservation measure was to mushroom, in parallel with the restorations of Michelangelo’s Sistine Chapel ceiling frescoes, which began in 1980, and Masaccio’s Brancacci Chapel frescoes, which began in 1981, into one the most protracted radically ambitious, corporately-funded and controversial restorations of modern times.
It can now be seen that 1977 marked the high water mark of confidence in the recuperative powers of restorers and in the legitimacy of their increasingly bold and experimental methods. In the previous decade, heroic actions in wake of the floods in Florence had carried restorers to unprecedentedly high levels of public respect (even when they opted to strip frescoes from walls). In Britain, following a spuriously engineered triumph with the restoration of Titian’s “Bacchus and Ariadne” at the National Gallery, criticism had been declared dead by the victors. The National Gallery launched its Technical Bulletin in 1977 and in it, the Gallery’s head of conservation science, Joyce Plesters, mused complacently: “one or two readers may recall the furore when the cleaning of discoloured varnishes from paintings…began to find critics”. In the same year, Kenneth (Lord) Clark published his two volumes memoir “Another Part of the Wood” and “The Other Half” in which he pronounced picture cleaning “a battle won” and claimed credit for having taken the first steps, as director of the National Gallery (1934-1945), by installing a “scientific department with all the latest apparatus”. He had done so not because he believed in the “application of science to the problems of cleaning”, but because “until quite recently the cleaning of pictures used to arouse extraordinary public indignation and it was therefore advisable to have in the background what purported to be scientific evidence to ‘prove’ that every precaution had been taken.”
Duping the public in such manner occurred in Italy. In 1981, a year after the start of the Sistine Chapel ceiling restoration in Rome, the restoration of the Brancacci Chapel commenced. Speaking of the prior tests made in connection with that restoration, the author Ken Shulman cites an Italian art historian (“Anatomy of a Restoration”, p. 156), who had said:
“Let’s be honest and admit what all restoration directors will say in private. At the beginning of any restoration, you order as many tests as you can imagine, fully aware that only about five per cent of them will be of any use during the restoration. The rest of the analyses are merely window dressing.”
With Leonardo’s “Last Supper”, amidst all the preliminary testing, no-one seemed concerned by the fly that was present in the ointment of Pelliccioli’s celebrated reductive, purist restoration: his liberation of Leonardo’s paintwork had come at a cost in terms of artistic legibility. A law of diminishing returns had been set in motion that would (as we will see in Part 2) produce panic and confusion among the restorers and their supervisors.

What Price a Smile? The Louvre Leonardo Mouths that are Now at Risk
There is an air of confusion, and even a whiff of crisis, in today’s international art restoration community. At the National Gallery’s CHARISMA symposium on Leonardo’s technical practices and influence (January 13-14), many fascinating and highly informative demonstrations were made of non-invasive imaging techniques. A ground-breaking paper by Ana González Mozo revealed how the Prado’s copy of the Mona Lisa had faithfully tracked Leonardo’s own revisions on the original work. Imagine – a copy not so much of the finished masterpiece but of its very genesis. The proceedings, happily, are to be published. Unfortunately, at this richly rewarding and even-handedly conducted event, two critically serious weaknesses emerged during the proceedings and discussions that seemed linked and together to constitute a wider international art conservation faultline.
That is, firstly, there are manifest deficiencies of understanding on the crucial relationship between the discoveries that are being made through advances of technical analysis, and the original painterly/artistic means by which the art-objects-under-investigation were produced by artists in the first place. This single shortcoming carries profound cultural and professional consequences and is, we believe, a root cause of many of the controversies which arise in the field. Secondly, and concerning these controversies, a number of speakers (particularly Italian speakers, as it happens) used their papers to dismiss critics of their (sometimes long-past) restorations. Such combative unrepentance suggests how hard the task remains to establish some proper and effective systems and habits of disinterested critical appraisal in what is becoming an alarmingly expanionist and self-authorising and validating field. Much might be gained if restorer/conservationists themselves would devote more energies to those fruitful knowledge-advancing studies that leave vulnerable and uniquely precious historical works of art intact and free from what too often seem injudicious or debilitating interventions.
For some speakers, “virtual” indications of changes within pictures, seemed to be taken in themselves as invitations to swabs-on interventions. Certainly it seemed tactless and provocative when, at a time of great disputation, a Louvre curator, Vincent Delieuvin, ended a talk on non-invasive examinations of the museum’s Leonardo “Virgin of the Rocks” with the bald declaration “Restoration of the painting is possible”. Possible? No doubt it is politically so today at the Louvre, but desirable even under the present controversial circumstances? And what exactly has made this hitherto untreatable picture (see caption at Figs. 2 and 3) treatable? Must every restored masterpiece immediately trigger another? Will curators and their restorers never allow decent intervals for the fumes to evaporate and for their handiwork to be evaluated with due attention and consideration after the inevitable PR media barrages that nowadays accompany all major restorations? For that matter, is no one in authority concerned by the general and wider risks that are being incurred in the current Leonardo binge in which the oeuvre itself is being speculatively “grown” even as its most secure works are being recast by today’s more adventurous generation of technicians?
Concerning the Louvre fracas, Didier Rykner, surprised and disappointed us in his Art Tribune post of January 7th by disparaging the international debate on the restoration of Leonardo’s “The Virgin and Child with Saint Anne”, that followed a Guardian report. Headed “A follow-up to the Debate…” that somewhat churlish post afforded a proxy defence of the Louvre’s current policy. Of the momentous resignations of Sègoléne Bergeon Langle, the former director for conservation at the Louvre and France’s national museums, and Jean-Pierre Cuzin, a former director of paintings at the Louvre, from the Louvre’s own international advisory committee, Rykner complains that the restoration has sparked a debate “when in fact nothing new has happened since since the month of October (see our article in French).” One thing that is new is that everyone now knows (thanks to the diligence and reach of the international press) what very few previously appreciated: a profound schism exists over picture restoration methods at one of the world’s greatest museums – in truth, the world’s greatest single museum – and, that the restoration of a major work of the world’s most famous artist is the centre of that dispute.
Rykner characterised the “Virgin and Child with St Anne” restoration as one in which only “three points had to be solved”, when, far from being some problem-solving exercise, this is a debate about the very nature and legitimacy of actions that might be made on an immensely complex, unfinished, ancient and precious masterpiece. Restorations never take place in antiseptic clinical spaces. They always reflect philosophies, interests and professional inclinations or dis-inclinations towards radical interventions. Conflicts in this arena are far from trivial and it is desirable that they should not take place in the dark.
There is great irony in the present situation. For many years after the Second World War, the Louvre occupied the virtuous conceptually elegant and restrained end of the restoration spectrum. And it did so in explicit opposition to the brutal simplistic campaign of “total cleaning” launched at the National Gallery by the restorer Helmut Ruhemann, who insisted that “important paintings should be thoroughly cleaned before we theorise about them”. Ruhemann’s influence at the National Gallery was under-written by the long-serving post-war director Philip Hendy, who wrote in the catalogue to the didactic 1947 exhibition of pictures cleaned (in secret) during the war: “The purpose of this exhibition is not only to do justice to the cleaned pictures, but, by extending the knowledge of their condition, to bring about a higher standard of criticism in this all-important subject.” By 1958 Bernard Berenson had been persuaded that “the recent restorations of pictures in the National Gallery are defended by most English people against the almost universal disapproval of continental craftsmen and critics.”
Berenson was right about the continental opposition but, perhaps being overly-reliant on the reports of Kenneth Clark (who had launched the National Gallery’s cleaning blitzkrieg in the late 1930s when he had hired “the brilliant Ruhemann”), he had quite missed the scale and the ferocity of opposition within England. In 1947 Hendy had made the self-defeating claim that: “There would not in all probability have been so much criticism of the appearance of the pictures cleaned since the war began if the public had been kept waiting until the cleaned pictures could be shown as they are shown [all together] now. Instead, they had to be scattered among the dirty pictures upon walls which there had been neither time no labour even to brush down after six years of increasing exposure to the elements.” If Hendy could not see the force of a widespread preference for “dirty” over “cleaned” pictures, by 1977 his predessor director, Kenneth Clark had quite forgotten the controversy the returned pictures had provoked: “A cleaned picture often looks very bright when first it is finished, but it loses its shine after a year or two, and I was fortunate in that the pictures I brought back for the reopening of the Gallery, all of which had been cleaned, had had time to ‘settle down’. No one complained about them.”
For a concrete example of the war-time consequences of Ruhemann-esque preludes to theorising, see Figs. 9 and 10. For a discussion of the role of the German restorer, Johan Hell, whose highly restrained work in Britain earned much support among artists and private patrons, see this author in the June, July/August and September 2006 issues of the Jackdaw. Hell’s great influence in Britain (he restored the collection of the Dulwich Picture Gallery to acclaim) was carried to the United States, albeit in dilute form, by his sometime student, John Brealey. In 1951, René Huyghe, the Louvre’s chief curator of paintings and drawings advised restorers and curators “If there is the slightest doubt, stop; for in this matter it is inadmissible to make a mistake. Excessive prudence leaves the future open without compromising it. But mistakes made by presumption are irreparable.” In the Sunday Times (15 January 2012) Bergeon Langle said “We prefer the most moderate cleaning possible. But my views weren’t taken into consideration.”
Not heeded, perhaps, but widely noted nonetheless. The debate that has been opened by the two Louvre resignations shows no sign of abating. In a recent article Bergeon Langle has further explained: “I deemed that the restoration was not being carried out in line with what I imagined was necessary for this Louvre painting. That is my firm belief.” We now learn through such increasingly frequent press reports and the assorted leaks and briefings on this schismatic dispute within the museum’s twenty members strong advisory committee, that the Louvre’s present curators, with the encouragement of certain English and Italian curator and conservator members of that committee, are resolved to pursue more radical, less precautionary treatments. What makes this dispute-among-experts so alarming is that evidence of the consequences of the shift from caution and physical restraint within the Louvre already exists – we don’t have to read the book (and the official accounts, should they ever be made available), we can simply look at the pictures: as previously shown, restorers at the museum may now change and then re-change the expressions on old master faces without even being required to record their adulterations in the museum’s dossiers. This, by any standards is an already extraordinary and indefensible position.
News of the Louvre resignations comes just seven months after the shocking disclosure of its cosmetic facial exercises and at the point where the cleaning of the “St. Anne” is completed and the perilous stage of retouching begins. It so happens that the expression of St. Anne’s mouth is interrupted by a panel join (see Fig. 1) which might provide another temptation for a little cosmetic surgery with the retouching brushes. We were not reassured when the Louvre’s present head of painting, Vincent Pomarede said recently that the retouchings would be “reversible”. “So what?”, we would ask. As shown right (Fig. 5), the Louvre recently made two egregious errors on a single Veronese face. That the second falsification – which is still in place – is theoretically as removable as the one it superseded does not mitigate the presently persisting offence and lapse of curatorial vigilance. The two members of the Louvre advisory committee from the National Gallery who have been enthusiastic supporters of the current restoration (the then curator Luke Syson, who has moved to the Metropolitan Museum, New York, and the head of conservation, Larry Keith), happen themselves to have been responsible on their own patch for another incomprehensible, initially unacknowledged (- even in the Gallery’s own Technical Bulletin report) but again “reversible” alteration to a (Leonardo) mouth – see Figs. 6, 7 and 8.
One of the more monumentally controversial restorations defended at the National Gallery symposium was that of Leonardo’s “Last Supper” by Pinin Brambilla Barcilon. Sponsored by the Olivetti corporation, the restoration had been directed by the distinguished Leonardo scholar Pietro Marani, who is a member of the Louvre’s “St. Anne” advisory committee, and like Syson and Keith an enthusiastic supporter of the present restoration. When we pointed out at the conference that the previous restoration of the “Last Supper” in the 1950s had been praised at the time by Bernard Berenson as an ultimate recovery of all the surviving authentic Leonardo paintwork, Pietro Marani countered by claiming a right for each generation’s restorers and curators to impose their own values and interpretations on historic works of art. The consequences for Leonardo’s “Last Supper” of the claimed (“Buggins’ Turn”?) right to undo and redo every great work of art, will be examined in our next post.

It seems to be being claimed now that scientific tests have shown that the painting can safely be restored. Given a) the extremely cracked and irregular surface; and, b) the extraordinary subtlety of the modelling that attaches to the individual fragments of the paint but works artistically across them and despite their physical and optical disruptions, it is hard to imagine what assurances “scientific analyses” might offer in support of taking the sheer risk of working upon such a painting with solvents which are notoriously invasive and pentrating and love nothing better than a good crack through which to advance themselves. Would a restorer attempt to clean each item of paintwork individually or work across several at a time while attempting to preserve the immeasurably subtle artistic relationships that would be out of sight underneath the solvent-laden and abrasive swab?
“Put on the carnations with silk brushes, and while they are fresh you can make the shadows as vaporous as you will. The carnations should be painted with white, lake, and massicot; the shadow should be of black and matoric (massicot), with a little lake and black. When the picture has been sketched in lightly, let it dry and then retouch it with lake soaked in gum-water, and this should have been left some time in gum-water, because it is thus better, and will not have any lustre when it is used…”
The scholar of Leonardo’s painting techniques, Jacques Franck, has adduced that the “vaporous” subtlety of expression encountered here could only have been produced by minute touches of brushwork applied in multiple glaze layers, and has warned that with such a blur of superimposed micro-layers of vulnerable glazes, one could not be sure that the solvent used, even in the course of a very gentle cleaning, would not cause inevitable damage, whether in the ultra delicate zone of the mouth or elsewhere. As it is, any gum-bound pinks have long since faded or perished at restorers’ hands, along with the Mona Lisa’s eyebrows – which have survived on the Prado’s copy.
In between the two photographs (the post-cleanings photographs are grey-scale conversions from the large colour plate in the 1990 edition) this painting was restored twice by the Gallery, in 1940 and in 1981-82. It was said of the first cleaning that it had been undertaken because the picture was “much disfigured by dark spots and discoloured varnish”.
The second cleaning was undertaken because “The picture is still blistering. There are numerous old small retouchings, obvious repairs along the cracks and a large hole in the green robe lower left…[and because there was a] discoloured layer of old varnish with some blanching.”
The treatment report after the second restoration read: “The discoloured varnish and retouchings were removed with propan-2-ol and white spirit leaving a thick greyish layer of surface dirt and varnish remnants which was removed with a potassium oleate soap. The blisters were laid with gelatine and the painting restored with pigments in Paraloid B-72 and varnished with Ketone-N.”
It should be said that we are greatly indebted to the National Gallery for making its conservation records and photographs available to us. In this particular case, in setting out the post, we queried our own scanned post-cleaning photographs and re-scanned them as a precaution. The second scan was identical to the first. Thus, in so far as the (Gallery’s own published) photographs are reliable, the viewer may fairly make here an appraisal of the artistic cost (in terms of lost tonal differences; lost modelling of forms; lost details – as in curls of hair, for example) that was paid for the removal of the disfigurement represented by spots of darkened retouching. Moreover, such trade-offs, which are surprisingly common in museum restorations, are rarely strictly necessary – or necessary at all. Jean-Pierre Cuzin, the former director of paintings at the Louvre who resigned from the St Anne advisory committee, was of the opinion that the discoloured touches on the St Anne could simply have been repainted. (The varnish had been thinned, replenished and regenerated on a number of occasions since the war.) Such retouching practices are common: aside from its two major cleanings and restorations, this Pontormo had simply been retouched in 1955 – and again in 1979, just two years before its second cleaning.
Perhaps the last word should be given to Sègoléne Bergeon Langle who has recently commented: “As a general rule, I prefer old works to be cleaned only very lightly. You can never retrieve the original colours, what you get instead is the current state of the painting materials. Leaving a slight veil over the work makes it more harmonious.”
The Louvre Leonardo Restoration Committee Resignations
The Great Louvre Picture Cleaning Controversy has crossed the Atlantic. Following the Guardian coverage reported in our previous post, the New York Times’ Paris Correspondent, Elaine Sciolino, today covers yesterday’s meeting (January 3rd) of the Louvre’s international advisory committee on the restoration of Leonardo’s “Virgin and Child with St Anne”. Ms Sciolino’s account likens the current internal professional crisis of confidence at the Louvre to the controversy over cleaning methods that followed in the wake of the restoration of Michelangelo’s Sistine Chapel ceiling frescoes in the late 1980s and the 1990s.
The departure from the Louvre’s advisory committee of two such eminent authorities as Ségolène Bergeon Langle, the former director of conservation for the Louvre and France’s national museums, and Jean-Pierre Cuzin, the former director of paintings at the Louvre, comes at the moment when the “Virgin and Child with St Anne” enters its second and (– as we have seen with the repainted angel’s face in the National Gallery’s version of Leonardo’s “The Virgin of the Rocks”) inherently perilous phase of retouching. Louvre spokesmen, in their official justifications for a provocatively radical and inescapably controversial cleaning, are seemingly in denial of the significance of the events now reverberating around their heads.
Madame Bergeon Langle’s timely and sagacious warning that “Despite great progress in our competence we need to be driven by modesty. Better and more controllable materials are yet to be discovered” can only give heart to those critics who have been horrified by the Gadarene Scramble for newsworthy restorations in which too many major museums and galleries have already participated.

Something Not Quite Right About Leonardo’s Mouth ~ The Rise and Rise of Cosmetically Altered Art
In the conservation of art, the impulse “to do” is the most dangerous of all. There are so many ways in which picture restorers can, through misreading or misunderstanding, injure art. Unfortunately, there are also many ways of promoting injuries as triumphs. Worst-case injuries can be spun as dramatic “discoveries” and “recoveries”. With the Sistine Chapel ceiling restoration – perhaps, an all-time worst case – the last stages of Michelangelo’s sculptural painting were washed away with oven-cleaner-like chemically-laced thixotropic pastes and copious applications of rinse-water (see Fig. 1 and our earlier post). To sanction the unexpected and unprecedented changes, a “New Michelangelo” of art history-changing, colouristic brilliance was invoked. The surprise outcome was presented, post hoc, as having demolished the “Darkness Fallacy” and the “Sculptural Fallacy” of Michelangelo’s legendary, much-copied and commented-upon work. Less technically experimental methods can also produce serious alterations during a single intervention (see Figs. 2 & 3). Not always immediately noticeable but ultimately no less invidious are the cumulative “Chinese Whispers” changes made as successive restorers undo and redo their predecessors’ work. A case in point of the latter – and of the defences that get offered – can be seen in successive treatments of the London version of Leonardo’s “Virgin of the Rocks”.
The cult of unexpected and dramatic discoveries grew out of earlier (spurious) claims of scientifically underpinned restoration methodologies. “Picture surgeon” restorers mimicked the conventions and vocabularies of medicine with its “diagnoses”, “research”, “interns” and “treatments”, and ended by believing their own easel-side manners and propaganda. In truth, they have always more closely resembled cosmetic surgeons and it makes cultural sense to consider these twin spheres together. Both promise to reverse Time’s effects. With both, adverse consequences are often slow to be recognised. With human cosmetic surgery, everyone has recently learned of the horrors of industrial-grade silicone breast implants and Trout Lips. News has recently begun to emerge of the unanticipated consequences of radically invasive attempts to put the very fabric of paintings into perpetual good health. The National Gallery now concedes that its former penchant for ironing large masterpieces (like Titian’s “Bacchus and Ariadne”, Seurat’s great “Bathers”, and Sebastiano’s “The Raising of Lazarus”) onto sheets of industrially manufactured pressed-paper (Sundeala) boards has bequeathed pictures that can no longer be moved safely.
Both zones of surgery prove prey to stylistic fashions as the distinctive nips, tucks and nose-jobs of one period swiftly become démodé. A worst-case example of multiple botched treatments occurred recently at the Louvre. It was reported in the French and British press, in our Journal (see Fig. 3) and in our post of 28 December 2010. The Louvre’s controversial restorations continue to make headlines. One of our greatest concerns is that no picture restorer ever seems able to resist undoing and redoing (Fig. 4) the painted interventions with which predecessors left their imprints on masterpieces. That there may be some cultural/pathological root to such tampering should perhaps be considered. It sometimes seems as if restorers reward or indulge themselves with a little fancy creative brushwork after the tedium of a long cleaning. In 1998, a restorer, John Dick, working on Titian’s “Diana and Callisto” at the the National Galleries of Scotland told Scotland on Sunday (29 March 1998):
“Most of the areas I will be painting are so small I will not have to invent anything. I will simply have to match the colours to the original. It will be more difficult when it comes to improving Titian’s contours, which I know I will be tempted to do, but which can be dangerous. I will consult with other conservators and with the director [Timothy Clifford]. In the end, a decision has to be taken but if it does not look good it can always be taken back off again.”
Whether restorers are taking off or putting on, restorations never take place in vacuums. There is always a context that is comprised of a singular balance of forces and interests. These forces are various and competitive, being sometimes personal, sometimes professional, sometimes institutional; sometimes local, sometimes national, sometimes international; sometimes technical, sometimes philosophical; sometimes political, sometimes financial. But if there are rival, inter-acting sociologies or cultures of restoration, these always find expression in the individual acts of restorers upon individual, unique and historical works of art. It is therefore incumbent on those who authorise or sanction restorations to permit/guarantee absolute transparency in restoration procedures and methodologies. In this respect the National Gallery has recently made enormous strides. Under the Gallery’s present director and its previous director, ArtWatch UK has been given full and generously helpful access to conservation and archival records. The Gallery publishes in its annual Technical Bulletins much material on its own workings in conservation. Nonetheless, some old habits die hard. The best-reported conservation activities in the bulletins tend to be in the most neutral areas – in technical analyses of materials, applications of imaging systems, and so forth. The least adequately reported activities are precisely the crucial hands-on physical interventions of restorers.
Over the years, we have formed an opinion on this lacuna. There is a problem for the Gallery in fully acknowledging and showing what individual restorers do, because they do different things, each according to his own inclinations and talents. Taking the recent restoration of the “Virgin of the Rocks” as our case in point, let us first look in from “the outside” at the broader context. As we have discussed before, this was a restoration whose celebration (in what was to become a £1.5 billion exhibition) was planned before the restoration itself had even begun. As we have also previously discussed, the Gallery has proudly published its policy or “philosophy” of restoration treatments. Its handbook “Conservation of Paintings” acknowledges that pictures are now “changed primarily for aesthetic reasons” (p. 53) and (p. 45) that restorations are carried out on the “aesthetic objectives of those responsible for the cleaning”. Moreover, (p. 53) although the “different aesthetic decisions” taken by individual restorers produce results that “may look very different”, all of such different outcomes are “equally valid”, provided only that they have been carried out “safely”. These are alarming claims: in matters of aesthetic and artistic integrity, the “safety” or otherwise of the cleaning materials is a red herring: if pictures end up looking different, they are different, and these differences are material and irreversible.
The proof of the National Gallery’s restoration pudding is in the eating – which is to say, in our looking. In the Gallery’s current Technical Bulletin (Vol. 32), Larry Keith, Ashok Roy, Rachel Morrison and Peter Schade, say of the restoration of the “Virgin of the Rocks” that while its practical intent was “primarily aesthetic” it also served to provide an example of the Gallery’s interdisciplinary approach:
“Whenever possible, major restorations are intended as the hub of a wide range of research activity that sees curators, scientists and restorers working together – increasingly alongside colleagues from other institutions”.
The significance of such extra-conservational purposes of restorations should not be overlooked or underestimated: much of the credit for the present historically unprecedented coralling of quite so many Leonardos in one place at one time, has been given to the international connections and diplomatic skills of Gallery staff, as seen in their increasingly close relations with other major institutions such as the Louvre. As it happens, the relationship with the Louvre is proving more problematic and embarrassing than the Gallery might have anticipated. It has recently been reported that among the membership of an international advisory committee set up by the Louvre to advise on and monitor the restoration of Leonardo’s “The Virgin and Child with St Anne”, the two members who proved the most enthusiatic advocates of a more, rather than a less, radical cleaning of the painting, have been the National Gallery’s head of conservation, Larry Keith, and the curator of the current Leonardo blockbuster, Luke Syson.
One of the calling cards that Syson and Keith will have had on the international advisory committee has been the generally ecstatic art-critical reception of the restoration of the “Virgin of the Rocks” and of the blockbuster exhibition it had kick-started. Richard Dorment’s praise for the restoration was unreserved:
“This sense of interaction is palpable too in the National Gallery’s version of the Virgin of the Rocks, which until its recent cleaning was considered to be a slightly inferior version of an altarpiece in the Louvre. But when it emerged last year from the studio of Larry Keith, the National Gallery’s director of conservation, the refinement of the detail, depth of field and exquisitely calibrated tonal harmonies made it apparent that only Leonardo could have painted it, with little or no intervention from his studio assistants.”
How remarkable, perhaps, that so many people could now see, having been told what was to be seen, what so few, unaided, had seen before – an iffy, “not-altogether-Leonardo” had not only beome an “altogether-Leonardo” but a Leonardo that was now more than a match for the previously superior Leonardo. But Dorment’s acceptance of the claimed elevation would have been sweet music to Gallery ears – as must also have been his drum roll for the blockbuster show’s creation and his apparent endorsement, even, of its terrifyingly hazardous back-scratching corrolaries:
“Earlier this week, the National Gallery in London announced a historic collaboration with the Department of Paintings at the Louvre. The French have agreed to lend their version of Leonardo da Vinci’s Virgin of the Rocks to the eagerly awaited Leonardo da Vinci exhibition that opens at Trafalgar Square in November. A few months later, the English will repay the debt by sending Leonardo’s highly finished preparatory drawing The Virgin and Child with Saint Anne and John the Baptist (the Burlington House Cartoon) to Paris, where it will hang in close proximity to the painting it was made for, which is owned by the Louvre.”
Leaving aside the risks of lending the hitherto unlendable Cartoon, with the restoration of the London “Virgin of the Rocks”, we had initially been somewhat reassured to have been told that this was not to be an aggressive restoration; that while it would greatly thin the varnish applied by Helmut Ruhemann in 1949, it would not entirely remove it. (Pace the Art Critics, it has never been made clear how a cleaning that ran from November 2008 to May 2009 and that had not removed all of the previously applied varnish, might somehow have disclosed an entirely autograph status throughout a picture that was variously painted and unevenly finished.) When it went back on show after its “moderate” cleaning, old anxieties flared: it was evident that, with its now violently assertive blues, the picture had not returned to its previous post-cleaning appearance in the 1950s and 1960s. For the latest detailed accounts of the restoration and for photographic records we turned to the current Technical Bulletin (No. 32).
Comparing the large image of the angel’s face that is carried on the cover of the present Bulletin, with the best previous images (seen at Figs. 5 – 8), it was apparent that changes had occurred in this important and sensitive area. The most dramatic of these was to the most expressive feature – the angel’s mouth. With Leonardo, of all artists, a degree of circumspection in the restoration of his mouths might be expected. (Who would lightly change the expression of the “Mona Lisa”?) Instead, we encountered a full-blooded change to the design of a mouth on a face that had been held by one scholar and former director of the National Gallery, Kenneth Clark, to be exclusively the handiwork of Leonardo himself and the section of the painting in which the artist’s finishing glazes had best survived: “this is the one part of our Virgin of the Rocks where the evidence of Leonardo’s hand seems undeniable, not only in the full, simple modelling, but in the drawing of the hair.” Where Clark had seen a clear superiority in the head of the angel over that of the Virgin, in the 1990 re-publication of his book, a note was added saying that “As a result of the cleaning of the altarpiece in 1949 the differences between the heads are rather less apparent.”
The recent redrawing and remodeling during a restoration has cast the far side of the mouth downwards and left the upper lip no longer tucking enigmatically into the cheek in the manner so frequently encountered (see photographs, right) as effectively to constitute a trademark Leonardo/Leonardo school signature. The photographic evidence raised two questions: What had been done? Why had it been done? We returned to the Technical Bulletin.
No answers were to be found. There was no explanation because there was no mention or account of any change having been made to the mouth. As so often, the Bulletin’s authors favoured the general over the particular. We learnt that “The intent of the cleaning was to effect the desired aesthetic improvement through the reduction of the old varnish, not simply to remove it, and in the main a very thin remnant of that layer…remains on the picture.” This deepened the mystery: if a thin layer of Ruhemann’s 1949 varnish had remained over the face, and if this layer had not been injured during the latest cleaning, why should any features have needed changing at all?
We asked the restorer, Larry Keith, if he had made any retouchings to the face of the angel. He replied that he had, but said that these had been confined to areas of damage and or abrasion. Specifically, he said that he had not introduced any new elements. This seemed at variance with the photographic record, insofar as we were in possession of it. That the mouth had changed was beyond doubt: we had record of its condition in photographs of 1938 (Fig. 5) and 1947 (Fig. 6). When Kenneth Clark’s 1938 book of details of paintings in the National Gallery was reissued in 1990 it was with new (this time, colour) photographs. We thus had a record (Figs. 5 & 6) of the angel’s face before the Second World War and, crucially, before Helmut Ruhemann’s 1948-9 restoration. We had a record of 1990 that showed the post-Ruhemann state (see Fig. 7). The mouth might have been weakened by Ruhemann (see Figs. 15 & 16) but its disposition – which had conformed to that seen in an x-ray photograph of 1947 (Fig. 19) – had survived. Ruhemann had, however, chiselled away the end of the nose so as to bring it inside the contour of the face (Figs. 5, 6 & 7), as is the case with the angel in the Louvre version (Figs. 9 & 10) but was seen not to be the case in the 1947 x-ray photograph of the London picture (Fig. 19). Keith has retained Ruhemann’s revision of the nose which had undermined (for reasons to be examined on another occasion) the coherence of the head’s perspective .
Clark’s book had again been re-issued in 2008, this time with distinctly superior new, digital colour photographs (see Fig. 8). At this late date, the mouth showed no change. So when, in November 2008, Larry Keith’s restoration began, the published photograph of that year effectively constituted a pre-treatment record, and the cover photograph of the angel on the current Technical Bulletin constituted a post treatment record. In between the two, the changes to the face had occurred. (To show the changes to the mouth more clearly, the painter Gareth Hawker tonally adjusted the 1938, 2008 and 2011 photographs seen at Fig. 4 so as to bring them to some tonal parity.) In view of the dramatic change to the mouth and the absence of any signs of losses or abrasions that might have preceded the repainting, we requested photographs of the angel’s face taken immediately after cleaning (but before retouching), and after retouching. These were kindly supplied. They confirmed that the mouth had been changed by retouching (see Figs. 17 and 18) but the pre-retouching photograph gave no indication of injuries or losses that might have required treatment. We therefore asked Keith, on what basis he had made his painted changes to the mouth (and elsewhere). He did not reply.
Some weeks later Luke Syson replied on Keith’s behalf, saying that as the curator of the work, he had been responsible for monitoring and advising on all aspects of the restoration and was therefore the person carrying the responsibility for answering all questions, including our own, about the restoration. Unfortunately, in this professional capacity, the curator, too, preferred to talk in the generality and to explain the restorer’s approach to the painting “as a whole”. I replied that, on the evidence of the Gallery’s two photographs, it was clear that features in the angel’s mouth which had survived both the Ruhemann cleaning and Keith’s own cleaning had been painted out. Would he explain, I asked, the thinking behind the alterations, and why changes to so sensitive and highly expressive a feature had not been discussed or acknowledged. I added that in my examination of the Gallery’s conservation dossiers I had encountered other instances of un-discussed and un-acknowledged changes made by restorers – including a major change to the Leonardo Cartoon.
In replying, Syson first said that he had reviewed the photographic evidence but could see no evidence of any deviation in Keith’s retouching from the procedure that he (Syson) had previously described. This was a depressingly circular bureaucratic response. Our concern had not been over command and management procedures at the Gallery, but over actual changes to specific and crucial features of a major and unique historical painting. Syson then claimed that the photographs showed that a single small damage had been revealed in Ruhemann’s 1949 cleaning and that he had retouched it. Keith, Syson added, had removed that single retouch to a small damage, in order to retouch it himself on the evidence provided by the surrounding undamaged paint. But this simply conjures a fresh mystery: how can noe restorer’s substitution of one small retouch of a single small loss by another restorer, have caused a mouth that formerly turned upwards at its extremity and tucked into a cheek, to turn downwards and cease to tuck into the cheek? However this might have happened – and clearly, something happened – where is the record of it?
As if in anticipation of such a question, Syson adds in conclusion, and in returning to his homebase circular bureaucratese explanations:
“Since this, as I’ve stated, is entirely in line with the approach taken elsewhere in the picture, there has been no need separately to document this part of the work.”
Between 1945 and 1994, Vermeer’s poor “Lady Seated at the Virginal” received no fewer than nine bouts of “treatment” – including being lined twice within three years. The last treatment (in 1994) was entered into the conservation dossier as “Retouching in face and neck corrected (Bomford) Surface cleaned, revarnished“. No photographic record of this intervention was to be found. When asked, the restorer, David Bomford, said that this was because: “there were no real changes – it was simply a matter of glazing a few small sections of the previous retouching which had discoloured slightly.” When our colleague, Michel Favre Favre-Felix, of ARIPA, noticed the second repainting in 5 years of the Veronese mouth shown in Fig. 3, and asked to see the Louvre’s documentation on it, he was told there was none because the repainting was but a “localised intervention“. A Louvre spokeswoman later described it as a simple sprucing-up (“bichonnée”) and added triumphantly: “That’s why you cannot find it in the painting’s dossier“.

Two “As Good as New”, Colour Contrasting Velazquezs ~ Thanks to the Fundación Iberdrola
Following the recent National Gallery restoration that launched a £1.5 billion Leonardo blockbuster, comes news of a brace of corporately funded restorations (- two pictures and a classical sculpture) at the Prado. The energy corporation Iberdrola is acting through its cultural off-shoot, “Fundación Iberdrola”, to “Raise awareness about the contribution of the IBERDROLA Group to society” by allocations of pre-tax profits dedicated “decisively to the promotion and dissemination of art and culture in the territories where IBERDROLA operates”. As part of its green image-building campaign of Good Works (which includes illuminating buildings at night and training young researchers in the energy field) the foundation has made itself “Protector Member” of the Prado’s “Restoration Programme” which encourages restoration research and trains restorers within the museum to the tune of 300,000 euros per annum.
Our prime fear with Art/Business relationships in the treatment of unique, historic and irreplaceable works of art has always been that the commercial tail might wag the custodial dog; might press for excitement and drama over minimalist judicious and restrained intervention; for more frequent rather than less frequent interventions – in effect, might expect big bangs for big bucks. A second concern is that corporate restorations receive over-hyped and propagandistic “Good News” promotion as instruments of miraculous “recoveries” and “discoveries”. This last practice compounds the problem of chronic unaccountability in art restoration. Restorers who work in-house at museums are, for obvious reasons, given full political protection for their actions however controversial or demonstrably harmful they might be. Museums rarely concede that even long-past restorations were harmful and almost never admit to recent – let alone current – injuries.
When reporting the Prado’s latest restorations, the online Artdaily.org, echoes Iberdrola’s own website account of the treatment of the monumental, paired paintings “Philip III on Horseback” and “Margaret of Austria on Horseback”. As the proselytising global energy giant puts it: “These paintings have been rehabilitated by the art gallery’s team of technicians with the backing of Fundación IBERDROLA as a supporting member of its restoration activity. The labour of specialists has allowed for recovering the original values of both portraits, which were significantly affected by the accumulation of dirt and the alteration of the varnish that had buffered the contrasts of colour”. Both accounts fail to appraise the Prado’s own before and after cleaning photographs which show changes that seem arbitrary and artistically injurious (see Figs. 1, 4 & 5). Such preparedness to accept on trust that the latest photographically recorded states are the best, most “advanced”, most reliably truthful – and even “original” – conditions of historic works of art reflects a wider and dangerous absence of properly critical appraisals of restorations. It would seem axiomatic that if works of art are to be altered (and then re-altered by the next generation) the processes concerned should be absolutely transparent and freely discussed. Artdaily trills that the paintings have been “fully restored to their original appearance” by the removal of a “veil” of dirt and “altered” varnish; and, that the restorers “allowed for the recuperation of [the pictures’] original values”. This is naive and illogical: if removing the “veil” had revealed the original paintwork, what would need to be recuperated?
The over-selling of restorations can distort scholarship itself. Where Artdaily describes the two pictures as having been painted by Velazquez with the help of assistants, Iberdrola speaks with possessive proprietary pride of “emblematic works of Diego Velazquez” now rightfully displayed in the same gallery as “Las Meninas” and “the other three renowned equestrian portraits of the artist”. This inflation traduces the labours of scholars. In her 1948 book “Velazquez”, Elizabeth du Gué Trapier (a member of the Hispanic Society of America) said of the Philip III that it is:
“by an unknown artist, or according to Beruete by Bartolomé González, retouched by Velázquez…Beruete wrote of Philip III’s portrait: ‘The greater part of the horse, the retouches of the armour, the horseman’s right arm, leg and foot; the stirrup, bit, the ornaments which hang from the horse’s croup, and the retouching of some parts of the sea-scape in the distance, are undoubtedly by his hand; one feels in them the lightness of his touch and his habitual precision and vigour. On the other hand, the forehead and the nostrils of the horse, as well as a great part of the background, were doubtless executed by the pupil Mazo.’ Beruete thought that Veláquez left the head of the King in its original state; others are of the opinion that he repainted it.”
More recently, in his posthumously republished Catalogue Raisonné (Taschen/Wildenstein, 1996), José Lopez-Rey describes a bewildering array of attributions and summarises that most scholars are agreed “on the strength of visual evidence that this equestrian portrait […had been] executed by a lesser hand and later reworked by Velázquez or under his direction”. Lopez-Rey adds that “Whoever the original painter of Philip III on Horseback, the painting has been visibly repainted, mainly the head, chest, forelegs and tail of the horse, possibly by Velázquez or an assistant in about 1634-35” and that by 1772 both Philip III and Queen Margaret had been extended from vertical to roughly square formats by additional vertical strips of canvas on both sides. Re Iberdrola’s hyperbole, Lopez-Rey draws distinctions between the entirely autograph Velazquezs “The Surrender of Breda” and the equestrian portraits of Philip IV and Prince Balthasar Carlos; the equestrian portrait of Queen Isabel, where Velazquez’s hand is “recognisable”, and the two recently restored works under consideration here, where that authorial hand is present only to a “lesser degree” in pictures “which were mostly executed by other painters”.
Given this consensus of uncertain authorial contributions, Iberdrola’s attempt to spin authentic Velazquez silk seems brazen when the Prado’s own before and after restoration photographs of the Philip III show so many artistically disturbing changes. During their latest restoration/recuperation, the sections of canvas that had been added to the sides of both paintings during the 18th century were cut off. Artdaily says that these additions had been made to make the paintings compositionally compatible with other works when installed in a new room in the Royal Palace in Madrid. The Fundación Iberdrola justifies stripping these historical extensions on the grounds that their removal has created a greater compositional contrast between the two pictures and the three great autograph Velazquez equestrian portraits of Philp IV, Isabel of Bourbon and Prince Baltasar Carlos. Artdaily describes the cleaning and the cropping together as having achieved the greatest possible recuperation of the “original perceptual conditions“. What is not acknowledged by either party is that this removal of historically resonant material has served to eliminate possibly discomfiting visual testimony to the original condition of the paintings (- at least insofar as it had survived into the 18th century) and made the task of gauging the effects of successive restorations almost impossible.
It can be assumed that when those strips were added, their values matched and seamlessly extended the then extant values of the two pictures (as with the repair to Michelangelo’s Sistine Chapel frescoes discussed in our April 1st 2011 post). What, therefore, might account for the mismatched values that had emerged and persisted (see right) until the recent twin restoration? The strips would likely have been painted by a single artist, in a single campaign and without need for making the numerous revisions and re-revisions by the assorted, variously attributed hands that are evident in the paintings themselves. It is unlikley that any paint layers in the extensions would have been made over already varnished paintwork and therefore be at risk of floating off during cleaning. Conspicuously, the most obviously exculpatory explanation for the mismatch of tones – that the additions had matched the values of the picture when under an old darkened varnish – has not been offered. The restorers reportedly attribute the mismatches solely to the technical fact that the bordering strips had been painted over darker ground colours than those in the paintings, and that this had somehow caused “the pigments in the two areas [to have] behaved differently over the course of the centuries”. This does not hold water: while darker grounds would certainly come to influence the values of the extensions as the overlying paint became translucent with age (as can most clearly be seen in the “see-through” of the first state of Philip III’s horse), it could not alone have done so to such striking (and varying) extents as have occurred in the two paintings. Whereas, the fact that darker grounds were used on the extensions would itself suggest an initial perceived need to match the then darker values of the paintings.
There is another reason for disregarding the current restorers’ explanation. If the dark ground theory were correct, the mismatch phenomenon would have arisen very slowly over time and not have – as the photographic record shows – lurched into being on successive restorations (see Figs. 2, 6 & 7). Artdaily has not shown before and after photographs of the Queen Margaret, which painting Lopez-Rey describes in the 1996 edition of his catalogue raisonné as having been restored in 1968. His post-1968 illustration is shown here in Fig. 2. However, in the 1978 edition of the book an apparently earlier (and presumably pre-1968 restoration) state is reproduced (see Figs. 6 & 7 for details of that state). At that date, the left-hand extension read only fractionally darker than the painting, and although the right-hand extension was appreciably darker it was less obtrusively so than was the case after the 1968 restoration. As described opposite, and as can clearly be seen in Fig. 7, the impact of the dark ground was neglible at the brightest part of the sky, on the horizon, where it might have been expected to be most evident. The original dramatically escalating darkness in the sky above those points should, therefore, properly be taken as part of the original tonal schema – and not as either accumulated filth or ground paint see-through. The similarity of the states in both paintings, as seen in Fig. 2, might suggest that the Philip too had been restored around the late 1960s. The differences between the pre and the post 1968 restoration states of the Margaret speak of massive changes of value being made during a single “treatment”. The horse, for example, was reduced from a deep rich chestnut to a tan colouring. That the earlier chestnut appearance had not been a by-product of some filthy misleading “veil” is demonstrable: the whites on the horse’s muzzle and upper left leg read as white not yellow or grey or brown. Whatever might account for the radical changes, it was not consistent with the removal of some overall disfiguring layer.
Characterising the surgical elimination of material that bears awkward testimony of an earlier, now irrecoverably lost state, as a recuperation of a painting’s “ original conditions” is naive and seriously misleading. With every restoration – however funded – the most urgent critical question must always be: “did it do any harm?” To answer it, we must begin by using our eyes and, perhaps, by heeding the advice of artists, one of whom reportedly asked “What’s that dirt called that the restorers clean off? Oh, that’s right – burnt umber.”
