Could the Louvre’s “Virgin and St. Anne” provide the proof that the (London) National Gallery’s “Virgin of the Rocks” is not by Leonardo da Vinci?
When the National Gallery’s restored “Virgin of the Rocks” was pronounced an entirely autograph Leonardo we were left reeling with incredulity. Picture restorers rarely decline opportunities to claim “discoveries” but could they really be claiming an ability to make a picture an autograph Leonardo simply by thinning its varnish? During the media frenzy of the National Gallery’s £1.5bn Leonardo blockbuster, its chief restorer, Larry Keith, was asked if a distinctive Leonardo brushstroke had emerged. “No”, he said, proof of authenticity lay in the picture’s internal relationships. Given that those relationships differ markedly from the ones present in the Louvre’s unquestionably autograph “Virgin of the Rocks”, what accounted for the discrepancies? The then curator, Luke Syson, replied that Leonardo’s style had, in the London copy, become abstracted, less naturalistic and more “metaphysical”. This seemed fanciful: had not all of Leonardo’s pictures carried a beguiling air of the metaphysical – and had this quality not derived from the artist’s preternaturally intense engagement with natural phenomena and the mysterious powers which operate through them? Had a new corroborating body of drawn studies emerged? The Gallery admits that not only is there no identifiable Leonardo brushwork but that the picture itself is “manifestly uneven in finish and execution” and that there has been “a good deal of agreement that Leonardo himself painted little or none of it”. When we asked if any securely autograph Leonardo paintings shared these newly claimed characteristics, Syson said that they were also found in the “Last Supper”, when only 20% of that large, fragmented, degraded, many-times restored, de-restored and re-restored mural survives – and when its recent restorers “discovered” that it had originally been choc-full of tiny naturalistic details (curtain hooks, slices of lemon, reflections on glassware, tablecloth patterns and so forth). Above all, the National Gallery’s latest upgrade flew in the face of – and seemingly sought to circumnavigate – a landmark 1996 article by a geologist (and now art historian), Ann Pizzorusso, who has shown that while the rock configurations in the Louvre version were entirely consistent with precise formations found in nature and in Leonardo’s own studies, those seen in the London version were found in neither. (See Pizzorusso, “Leonardo’s Geology: The Authenticity of the Virgin of the Rocks”, The MIT Press, Vol. 29, No. 3, and “Leonardo’s Geology: The Authenticity of the Virgin of the Rocks”, in Leonardo Magazine, Vol. 29. No. 3, 1996, pp. 197-200.) Here, Pizzorusso presents further elegant demonstrations of the London picture’s non-autograph status that are manifest in the (recently restored) late Leonardo masterpiece, “The Virgin and Child with St Anne”.
Ann Pizzorusso writes:
London’s National Gallery recently announced that its version of the “Virgin of the Rocks”, previously attributed to various artists who worked in Milan, was now, after being cleaned, solely the work of Leonardo da Vinci. The National Gallery supports its claims by stating that the work represents a change in style and that the geology in the picture is rendered in a more abstract, monumental style (see Appendix A).
While art historians have long discounted the National Gallery’s version as one by Leonardo, the Gallery has now discounted centuries of scholarship with their new interpretation and subsequent attribution of the painting to Leonardo. What is most ironic and troubling about the National Gallery’s position is that there are reams of contractual documents which still exist today documenting a 25 years long lawsuit concerning the two versions of the painting and which show, unequivocally, that Leonardo did not paint the version in the National Gallery. Prof. Charles Hope, a former director of the Warburg Institute, London, and an expert in notarial Latin states that there is no doubt that Leonardo painted the first version and not the second (New York Review, 9 February 2012).
While we may be able to forgive the National Gallery for not being up on notarial Latin, there is no excuse for their proposal that Leonardo changed his style. In the decades in which I have studied Leonardo from all aspects (we must remember, Leonardo did not consider himself primarily a painter) one thing stands out in all his works—a fidelity to nature and a lifelong effort to depict natural objects as realistically as possible.
The father of Leonardo studies, Carlo Pedretti, in his book analyzing Leonardo’s nature drawings, “Leonardo da Vinci Nature Studies from the Royal Library at Windsor Castle” (with a forward written by Kenneth Clark, a former director of the National Gallery in London), devotes the entire volume to discussing Leonardo’s preoccupation with natural objects and his fanaticism in attempting to depict them as realistically as possible. This passion was imparted to his students, Francesco Melzi, Cesare da Sesto, Giovanni Boltraffio and Marco d’Oggiono. So much so that a drawing of a Tree (RL 12417), long thought to be by Leonardo, was later attributed to Cesare da Sesto and a view of Amboise (RL 12727) to Francesco Melzi. In analyzing the works of Leonardo’s students one can see that they have followed Leonardo’s technique and depicted natural objects as realistically as possible. They had obviously heard quite a bit of ranting by Leonardo about “Botticelli’s bad landscapes” (see Appendix B).
Another reason why Leonardo’s approach is reflected in his art is that he was born in the transitional era of the late Middle Ages, an age still filled with superstition and fear, especially about such things as mountains, natural catastrophes and death. He grew up leading the way into the Renaissance, faced all these fears, and debunked them. He travelled extensively in the Alps outside of Milan taking note of nature and geology. He noted landslides and torrential flooding with its associated damage (see Figs. 3 & 4), he dissected corpses to provide the most accurate depiction of human anatomy we have ever had until relatively recent times. His work as engineer, geologist, botanist and astronomer cannot be disconnected from his work as an artist (see Figs. 8 & 9). To understand Leonardo, one must understand him completely. And to understand him completely is not difficult. He has written everything down. He was faithful to nature. If one applies just that one rule to Leonardo da Vinci, looking at his work from a scientific standpoint, the answer is crystal clear: fidelity to nature is a Leonardo trademark that can be used to determine the authenticity of his work.
Now that we have seen that the National Gallery has preferred not to acknowledge the work of many esteemed Leonardo scholars, maybe looking at the recently cleaned “Virgin and Child with St. Anne” in the Louvre will change its mind (see Figs. 1, 7, 10, 11, 14, 17, & 21). The “Virgin and Child with St. Anne”, dated to about 1510, came later than the National Gallery version of the “Virgin of the Rocks”. We do not know how much later, as the National Gallery has now dated the initiation of its version of the “Virgin of the Rocks” as 1491/2-9 and its completion to 1506-08. Professor Hope, in his review of the notarial documents regarding the lawsuit states that the National Gallery version of the “Virgin of the Rocks” could not have been painted before 1508.
If we use the 17 year time period (1491-1508) which the National Gallery cites for its “Virgin of the Rocks”, it would mean Leonardo was painting the “Last Supper” (1492-7/8), completing the Burlington Cartoon (1499-1500 or 1506-08) and the “Virgin of the Rocks” at the same time. On page 96 of Kenneth Clark’s book entitled “Leonardo da Vinci” he indicates that Leonardo was exceptionally busy. Apart from the first “Virgin of the Rocks” his time was taken up with work for the court. He was the court limner and also painted two portraits of the Duke’s mistresses Cecilia Gallerani and Lucrezia Crivelli. With these portraits, we would be up to five major works in progress by Leonardo if we include the National Gallery’s “Virgin of the Rocks”.
This being said, all of these works being done at nearly the same time gives us the perfect opportunity to appraise, determine and evaluate the stylistic traits of the artist at that period of his career. In looking at the Burlington Cartoon and the “Virgin and St. Anne”, both are rich with geologic detail and accuracy. Leonardo has risen to new heights in his portrayal of landscape elements. His talent and passion are vividly displayed in the Burlington Cartoon and he reaches a level of sophistication, subtlety and accuracy in rendering the geology in the “Virgin and St. Anne” which had never been seen before (see Appendix C).
The St. Anne is a geologic tour-de-force. In fact, Leonardo experimented extensively on developing paints and a technique for depicting the pebbles of agate, chalcedony and marble at the feet of the Virgin and St. Anne (see in particular, Figs. 1 & 21). Leonardo writes in his notebooks about his efforts and how satisfied he was to have developed an approach to rendering the pebbles in such a realistic fashion. In fact the entire painting is one geologic treat after another. He had spent years in the Alps so he knew the landscape and geology exactly. With his newly developed technique for painting marbleized pebbles he was delighted (- see Appendix D).
Using a date of 1510 for the “Virgin and St. Anne” and a date of 1483-86 for the “Virgin of the Rocks”, both in the Louvre, we have proof that Leonardo did not change his style, and that, if anything, he became more fanatical in his quest for geologic accuracy, developing new paints and techniques for natural depiction and driving his students to deliver the most accurate depiction of nature in their own works.
So we must ask the question “How and why could Leonardo have changed his style to produce a work so lacking in geological and botanical accuracy as the ‘Virgin of the Rocks’ in the National Gallery in London?” There is no evidence Leonardo changed his style and now, with the recently cleaned “Virgin and St. Anne”, we have that proof. We also know that his students were inculcated with his passion for accurate depiction of natural objects so we must also exclude his students as authors of the National Gallery work.
It would be best for the National Gallery to reopen the case for the attribution of the work to Leonardo. Hundreds of years of scholarship by Leonardo critics as well as the words and the works by Leonardo himself should not be discounted. The National Gallery does a disservice to those who have worked so hard to come up with incontrovertible evidence regarding the attribution of this work and most of all the National Gallery does a disservice to Leonardo himself.
The National Gallery’s claimed shift within Leonardo’s oeuvre
“We know that Leonardo’s painting technique gave priority to the figures. The Virgin is designed first, as she is in so many of his drawings, and the landscape seems to flow from her. Since Leonardo saw the painter’s acts of creation as analogous to God’s, his generation of the landscape in the Virgin of the Rocks and the absolute, unalterable perfection of the Madonna at the center could be understood as precisely connected with the doctrine of the Immaculate Conception. But the appearance of the Virgin and her companions, and of the plants and rocks, are different, in the two versions: the theological meaning of his stylistic choices has shifted slightly. In the Louvre picture Leonardo relies on entirely naturalistic tactics to give the picture its spiritual flavor: the sinless beauty of the Virgin becomes the same kind of truth as the natural beauty of the irises nearby. But in the London Virgin of the Rocks, the Virgin and Christ are supernatural, the world around rendered notably less naturalistically, the rocks are straightened to become great columns; the flowers appear to be ideal composites of the leaves and petals of real plants. Tackling the theme for a second time, Leonardo chose to show the viewer not just a vision of the Virgin Mary, but Gods’ perfect ideas for everything around her. What we are shown here is an ideal world made before the physical creation of our own imperfect cosmos, before the need for humankind’s salvation.”
The National Gallery catalogue, “Leonardo da Vinci, Painter at the Court of Milan”, page 174.
Leonardo on Botticelli’s bad landscapes
“He is not universal who does not love equally all the elements in painting, as when one who does not like landscapes holds them to be a subject for cursory and straightforward investigation-just as our Botticelli said such study was of no use because by merely throwing a sponge soaked in a variety of colours at a wall there would be left on the wall a stain in which could be seen a beautiful landscape.”
Leonardo da Vinci, from: “Treatise on Painting”, the chapter on Criteria and Judgments, the subsection “How a painter is not worthy of praise unless he is universal”.
“Saint Anne–that delicate place, where the wind passes like the hand of some fine etcher over the surface, and the untorn shells are lying thick upon the sand, and the tops of the rocks, to which the waves never rise, are green with grass, grown fine as hair. It is the landscape, not of dreams or of fancy, but of places far withdrawn, and hours selected from a thousand with a miracle of finesse. Through Leonardo’s strange veil of sight things reach him so; in no ordinary night or day, but as in faint light of eclipse, or in some brief interval of falling rain at daybreak, or through deep water.”
Walter Horatio Pater, “The Renaissance, Studies in Art and Poetry”, The Echo Library 2006, page 54.
“The movement of the fifteenth century was twofold; partly the Renaissance, partly also the coming of what is called the ‘modern spirit’, with its realism, its appeal to experience. It comprehended a return to antiquity, and a return to nature. Raphael represents the return to antiquity, and Leonardo the return to nature. In this return to nature, he was seeking to satisfy a boundless curiosity by her perpetual surprises, a microscopic sense of finish by her finesse, or delicacy of operation, that subtilitas naturae which Bacon notices. So we find him often in intimate relations with men of science – with Fra Luca Paccioli the mathematician, and the anatomist Marc Antonio della Torre. His observations and experiments fill thirteen volumes of manuscript; and those who can judge describe him as anticipating long before, by rapid intuition, the later ideas of science. He explained the obscure light of the un-illuminated part of the moon, knew that the sea had once covered the mountains which contain shells, and of the gathering of the equatorial waters above the polar.
“Notebooks and sheets of about 1508 contain a number of notes on ‘mistioni’ (mixtures), a plastic material of his own invention with which he aimed at imitating the colour and design of semi-precious stones. He describes his production process and how, once the objects were thus produced, he spent much time finishing them with his own hand to a smooth and glossy surface…At the same time he was much taken by anatomical studies, so that when he described the production process of his ‘mistioni’ he came to specify the effect that was to be achieved: ‘…then you will dress it with peels of various colours, which will look like the mesentery of an animal’.
“In 1502, Francesco Malatesta wrote Isabella d’Este that Leonardo had looked at many of the Medici gems and objets d’art made of stone. Leonardo praised ‘the one of amythyst or jasper as Leonardo baptized it, because of the admirable variety of its colours’”.

Rocking the Louvre: the Bergeon Langle Disclosures on a Leonardo da Vinci restoration
ArtWatch has been haunted for two decades by a nearly-but-not-made restoration disclosure. In the 1993 Beck/Daley account of the Nippon TV sponsored Sistine Chapel restoration (Art Restoration: The Culture, the Business and the Scandal), we reported that in the late 1980s Leonetto Tintori, the restorer of Masaccio’s “Trinity” in the Santa Maria Novella, Florence, and a member of the international committee that investigated the controversial cleaning, had “urged the Sistine team privately to preserve what he termed ‘Michelangelo’s auxiliary techniques’ which in his view included oil painting as well as glue-based secco” (p. 111). What we had not been able to say was that Tintori (who died in 2000, aged 92) had prepared a dissenting minority report expressly opposing the radical and experimental cleaning method.
Shortly before the press conference called to announce the committee’s findings, Tintori was persuaded by a (now-deceased) member of the Vatican not to go public with his views. He was assured that his judgement had been accepted and that what remained on the Sistine Chapel ceiling of Michelangelo’s finishing auxiliary secco painting would be protected during the cleaning. With a catastrophically embarrassing professional schism averted, the restoration continued and the rest of what Tintori judged to be Michelangelo’s own auxiliary and finishing stages of painting was eliminated. Without knowledge of Tintori’s highly expert dissenting professional testimony, the public was assured that despite intense and widespread opposition the cleaning had received unanimous expert endorsement. Critics of the restoration were left prey to disparagement and even vilification.
On January 4th, we noted that in the widely reported schism that emerged at the Louvre with the resignations of Ségolène Bergeon Langle, the former director of conservation for the Louvre and France’s national museums, and, and Jean-Pierre Cuzin, the former director of paintings at the Louvre, from the Louvre’s international advisory committee on the restoration of Leonardo’s “Virgin and Child with St. Anne”, it had been recognised that the resulting crisis of confidence was of a magnitude not seen since the Sistine Chapel controversy. Restoration advisory committees are not imposed on museums and customarily they serve as political/professional fig leaves. In the wake of the Louvre committee resignations, embarrassed and perhaps panicky members of the museum’s staff offered self-contradictory and unfounded assurances (see below). In January, the Louvre’s head of painting, Vincent Pomarède reportedly claimed that “The recent cleaning was absolutely necessary for both conservation and aesthetical reasons.” This assurance proved unfounded on both grounds. Pomarède added that no member of the committee “has ever said that the cleaning was not prudent and had gone too far technically.” One has now done so – publicly – and left museum restorations under an unprecedented spotlight.
During an earlier cleaning controversy at the Louvre, Edgar Degas threatened to produce an anti-restoration pamphlet that would be what he termed a “bomb” – but he never did so, so far as we know. Now, as Dalya Alberge reports in the Guardian, the French Le Journal des Arts yesterday published an interview with Ségolène Bergeon Langle of truly momentous if not incendiary consequence (see below). We learn that her resignation came after no fewer than twelve letters requesting information on the restoration’s course went unanswered; that it was made in specific and pointed protest against the use of retouching pigments whose safety had not been proven; and, that the Louvre’s public claims of some pressing conservation need to remove the varnish were false, having been made despite it being known within the museum that any potential threat to the paint came not from the varnish but from a single faulty board in the picture’s panel which was reacting to the museum’s insufficiently stable environmental conditions. Perhaps most disturbingly serious for art lovers are Bergeon Langle’s disclosures that along with old (but nonetheless still protective) varnishes, original material of Leonardo’s was removed – against her advice – from the painting; and, aesthetically, that it is confirmed that the modelling of the Virgin’s face was weakened (see Figs. 1 and 2; and, for weakening to the modelling of St. Anne’s face, Figs. 12 and 13).
That the Louvre authorities would not inform even so distinguished a member of its own advisory committee might suggest either that the restorers had not known in advance what they would be doing to the painting; or, they feared that disclosure of their intentions would provoke opposition within the advisory committee. Either way, this was clearly an unacceptable (if not improper) way for a museum to execute irreversible alterations to one of Leonardo’s most advanced sophisticated, complex and problematic works. To Bergeon Langle’s now public “insider” criticisms, additional detailed material to highlight further Louvre procedural shortcomings and misrepresentations to the press and to the public will shortly be presented by Michel Favre-Felix, the president of the Association Internationale pour le Respect de l’Intégrité du Patrimoine Artistique (ARIPA). Favre-Felix is also to call formally for the establishment of a national scientific ethics committee that would be independent of museums and their restoration teams and be charged with re-examining the conservation file on the challenged St. Anne restoration.
A second member of Louvre’s advisory committee, Jacques Franck, the world authority on Leonardo’s painting technique, has said to the Guardian that a restoration likely to generate such disapproval from leading figures should never have been undertaken in the first place and, given that Ségolène Bergeon Langle is unquestionably France’s highest authority on restoration matters, her alarmed protest is therefore one that should mean a lot to both Leonardo scholars and art lovers the world over.
Unfortunately, the restoration-induced changes on the St Anne are not unprecedented. It is Art’s general tragedy that while scholars have quietly enlarged the oeuvre of Leonardo over the last century and a half, restorers have repeatedly swabbed and scritched away at the surviving fabric of those precious works – sometimes to an astounding degree, as with the “Last Supper” in Milan. With the National Gallery’s substitute version of the “Virgin of the Rocks” we have seen how the distinctive Leonardesque expression on the angel’s mouth was altered (without any acknowledgement) despite the fact that a distinguished scholar and former director of the Gallery, Kenneth Clark, had seen the angel’s face as being “the one part of our Virgin of the Rocks where the evidence of Leonardo’s hand seems undeniable, not only in the full, simple modelling, but in the drawing of the hair”. It is a matter of note that four of the most enthusiastically supportive members of the Louvre advisory committee were drawn from the curators and restorers who were directly responsible for the London and Milan Leonardo restorations.
Of Leonardo’s accepted earlier paintings, in 1939 Kenneth Clark lavished especial praise on the treatment of modelling found on two portrait heads – and in his enthusiasm, he awarded the palm of best preservation to both of them. The “Ginevra Benci”, then in the Liechtenstein Collection but now in the National Gallery of Art, Washington, was judged “the best preserved of all Leonardo’s early pictures”; one that “shows most clearly his intentions at this period”; and, one where “within the light oval of the face there is very little shadow, and the modelling is suggested by delicate gradations of tone, especially in the reflected lights.” Clark thrilled to the great refinement of execution: “We see a similar treatment of form in Desiderio’s low reliefs, controlled by the same sensibility to minute variations of surface. There are passages, such as the modelling of the eyelids, which Leonardo never surpassed in delicacy, and here for once he seems to have had none of that distaste for the medium which we can deduce from his later paintings, no less than from contemporary descriptions of his practice.” Ever aesthetically alert and deft, Clark saw all of these ultra-refined technical devices as being entirely “subordinate to the feeling of individual character with which Leonardo had been able to charge his portrait, so that this pale young woman has become one of the most memorable personalities of the Renaissance.” (We are grateful to Carroll Janis for drawing attention to this passage.)
Clark’s alertness to the physical/aesthetic characteristics of Leonardo’s hand was to the fore in his reflections on the “Portrait of a Musician” at the Ambrosiana in Milan. In the “subtle luminous modelling” of its head and its “delicate observation of light as it passes across the convex forms”, this work could only be “by Leonardo’s own hand alone and unaided” and it was “very similar to that of the angel in the Virgin of the Rocks”. As it stood before 1939, this too was “perhaps the best preserved of Leonardo’s paintings”, and in it we were then able to “learn something of his actual use of pigment, elsewhere obscured by dirty varnish, and we see that it was less smooth and ‘licked’ than that of his followers.”
Ironically, Clark, with his pathological aversion to “dirty” varnish (which is to say, old varnish on an old painting on an old support), was more responsible than anyone for the subsequent museum restoration/stripping mania. Looking around today’s museums, it is hard not to conclude that Clark might have been more careful in his wishes. Bergeon Langle’s warning against the modern addiction to penetrative imaging systems is particularly apt and timely: the hyper-active restoration changes (see right) made to the modelling and to the expression of those precious living Renaissance faces have cumulatively thinned and abraded pictures surfaces and material components and thereby remorselessly pushed great paintings into sad resemblances of their own infra-red under-states (see particularly, Figs. 4-11 and 19 & 20). Technical curiosity kills more than cats. In the case of Leonardo it has contrived to pull that artist back from his own increasingly lush highly-wrought subtly atmospheric shading towards the brilliant but thinner decorous linearity of Botticelli, when any comparison of the “Mona Lisa’s” hands with those of Leonardo’s “Annunciation” would have warned precisely against such perverse and regressive adulterations.
The interview given to Le Journal des Arts of 27 April, by Ségolène Bergeon Langle read as follows:
Why resign from the Louvre’s scientific advisory committee for the St Anne? “In January 2011 the committee had agreed on a gentle cleaning of late varnishes and the removal of the stains on the Virgin’s cloak. Yet, between July and October 2011 a more pronounced cleaning was done and presented as ‘necessary’, which I objected to. I was then faced with people who would oppose my position, which is technical and not based on aesthetics. My 12 letters [to the Louvre] asking for precisions on some aspects of the cleaning process and on the materials to be used for retouching, remained unanswered. I had to resign (on December 20th, 2011) to be heard just on one specific point: the Gamblin retouching pigments were not to be used since their innocuousness is not proven. Right from the beginning, false ideas have been put forth, like calling ‘repaints’ original retouches by Leonardo in the work’s early stages, or to attribute flaking in the paint layer to the ‘contracting varnish’, a [consequence that was] actually due to the sawing up of the wood [panel]…”
What do you think of the work done? “In my opinion, the precautionary principle hasn’t been respected. We must face the fact that the Virgin’s face is less modelled now. The cleaning should never have gone so far. However, I was happy that the grove [of trees] be preserved and, also, the ground’s material constituents that some ‘felt’ not original (though between January and April 2011 a brown-greenish section of the ground, located below St Anne’s elbow had been removed already). Besides, another matter of much controversy, the whitened layer on Christ Child’s body, has mistakenly been understood as a late varnish [that has] gone mouldy. I’m inclined to believe it was an irreversibly altered [original] glaze and, therefore, I have recommended that it be preserved, but nobody would hear me.”
The current Leonardo exhibition implies that his other paintings in the Louvre should be cleaned also. How do you feel about that? “Just not to do it, by all means! The original flesh paint in the St John-the-Baptist, being rich in oil, displays a significant network of drying cracks and might be fragile in the event of cleaning. For sure, scientific methods are essential but they need sound interpretation and wisdom dually… To date, there is too much boldness originating mistakes and an alarming fascination for infra-red investigation whereby are revealed under-layers that were never meant to be seen.”
