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.

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
