Connoisseurship: Examinations, Debates and Snap Visual Responses

The rising tide of old master “sleepers” and “discoveries” carries great dangers and demands snap judgements. Some candidates for upgrades intrigue, some look dubious, some scream “Fake!” Last week two cases caught our eye.
Fig. 1, above. Fig. 2, below. The newly discovered “Lost” Van Gogh sketchbook (above, top) rang our and many other fake bells. Then came a report that a small “Florentine School” painting on a €3-4k estimate fetched €375k at auction as a sleeping Filippino Lippi (above, Fig. 1). A link to another small work attributed to the artist at the North Carolina Museum of Art (Fig. 2, below) showed pronounced, seemingly reassuring correspondences, but something jarred.
On connoisseurship we hold that every claimant work should be rigorously “interrogated” in three crucial respects. Technically, in its physical composition; by documentation on its known or claimed histories (provenance); and, above all, by visual analysis because, in the visual arts, every picture is its own prime historical document and its inbuilt historically-generated artistic relationships constitute the primary subject of art critical appraisal and evaluation.
Failure to excise bad attributions deceives the public and corrupts oeuvres. A good picture has nothing to fear from challenges. No amount of scrutiny constitutes a threat as good pictures outlive their doubters and can fight another day. Argument is healthy and a successfully repulsed challenge can increase understanding and enhance a good picture’s lustre.
Vincent van Gogh: The Lost Arles Sketchbook
Above, Fig. 3. The controversial lost-but-now-found Van Gogh sketch book above is by Professor Bogomila Welsh-Ovcharov, a Van Gogh authority whose claims of authenticity are supported by Ronald Pickvance, author of Van Gogh in Arles, but the cover’s supposed Van Gogh ink self-portrait announces itself as a draughtsman’s pastiche, as Mark Hudson noted in the Daily Telegraph (“A romantic story but can it really live up to its promise?”, 16 November 2016).
Above, Fig. 4. Simply by placing the supposed Van Gogh self-portrait next to an autograph portrait, immense and glaring differences become apparent: the author of the “discovered” drawing has abandoned symmetry with eyes of radically different sizes and a nose that seems product of a car crash. Throughout, the author mimics Van Gogh’s pen marks without comprehension of his form, power of design, and psychological acuity.
Above, Fig. 5. Instead of a form-camouflaging jumble of marks, the bona fide Van Gogh disports five graphically discrete component parts: a light-coloured jacket; a dark shirt and scarf; a varied but, on aggregate, mid-toned face; a light-toned hat with some mid and dark-toned form articulating shading; and, throwing all other values into relief, an agitated but tonally cohering background. Each of these spheres is allotted its own graphically purposive notations. The four images we show above for comparison are easily found online in historically successive reproductions. While these reproductions vary considerably, the force and artistic coherence of Van Gogh’s graphic intent and method shines through all.
Above, Fig. 6. If we place the bona fide Van Gogh between the clumsy mimicking newcomer and a masterpiece of the greatest graphic brilliance – van Dyck’s etched self-portrait – it is clear that the Van Gogh has more kinship with the latter than with the former.
Above, Fig. 7. And if we compare the Van Gogh with an entirely autograph van Dyck etched state of a figure we find a common use of a toned background that throws both subjects’ flickeringly brilliant lights and darks into relief.
The Van Gogh Museum’s objections to the “Lost Arles Sketchbook” and its track record on Van Gogh attributions
Above, Fig. 8. Prof. Welsh-Ovcharov (top) has responded to the Van Gogh Museum’s dismissal of the drawings with a rebuttal and a challenge to debate – thereby showing conviction and good faith. Her publisher reportedly characterises the proposed debate as “an opportunity to shed light on the conditions under which the Van Gogh Museum is claiming the de facto right to a monopoly of attribution.” This is a common plaint against authorities that block would-be, high-value attributions but our impression of the museum’s judgements is favourable.
In 2006 a Van Gogh – The “Head of a Man” owned by the National Gallery of Victoria in Australia (above left, on an easel) – was challenged by the art historian and Sunday Times art critic Frank Whitford when the portrait was loaned to an exhibition in Edinburgh. The newspaper asked our opinion and, when we demurred, sent a (revelatory) high resolution full colour compilation of all of Van Gogh’s painted portraits. We supported Whitford, saying to the newspaper (as reported in ArtWatch UK Journal, Spring 2008):
“The specific warning signs that should have alerted the buyer are:
“1] It is unique in Van Gogh’s portrait oeuvre
“2] It does not fit in the stylistic chronology that exists within that oeuvre. Compare it for example with the brushwork, colours and ‘attack’ of the Old Man with Beard, painted the year before that is in the Van Gogh Museum, and the Portrait of Camille Roulin painted a year or so later and that is also in the museum. There is an enormous but clear and logical development between those two pictures, from thick, laboured, relatively coarse brushwork to much more refined and ‘decorative’ marks – but both are entirely consistent and ‘all-over’ in their treatment.
“3] If its provenance goes back no further than Germany in the late 20s or early 30s, that is particularly unfortunate. Germany at the time was notorious for the certification by scholars (for a fee or sales cut) of dud works. The dealer René Gimpel has referred to the scandalous ‘amounts obtained by means of certificates given daily by German experts to German dealers. Just as there were paper marks, so there are paper canvases, an easy way of bringing dollars into Germany…The German title of Doktor impresses the Americans. The museums are even more intent than the collectors on defending their fakes or their mistaken attributions….’ By coincidence, in the current ArtWatch Journal [No 21], Kasia Pisarek cites the case of the great Rubens scholar Ludwig Burchard who issued so many optimistic certificates that he was unable ever to write his definitive book on the artist…She has identified over 60 Burchard attributions that have subsequently fallen. It was Burchard who first upgraded to Rubens the Samson and Delilah that is now in the National Gallery.
“I would add that the fact that it seems to be admitted that it is a cut-down canvas that was glued onto a panel compounds suspicions… Why should a (presumably) then only forty years old canvas, have needed gluing onto a secondary support? It might be worth asking the Gallery curators if any scholar has questioned the picture publicly or privately.
“It may be coincidence, but two of the pictures that ArtWatch has challenged in our own National Gallery, the Rubens Samson and Delilah and the Raphael Madonna of the Pinks, no longer retain their original backs. The former was planed down to 2 or 3mm thickness and glued onto a sheet of blockboard; with the latter, the family of restorers who sold the picture in the 19th century had (most unusually) polished the back of the panel thereby removing all historical evidence.”
As we have seen more recently, the claimed lost Leonardo drawing “La Bella Principessa” that emerged anonymously in 1998 had been glued to an old oak panel. Gluing canvases or drawings onto boards conceals half the material evidence. On 3 August 2007 Andrew Bolt reported in the Australian Herald Sun:
“The curious thing about the National Gallery of Victoria’s fake van Gogh is how easily it was spotted as phoney once it went on tour…. For more than 60 years this painting hung in the NGV without anyone screaming ‘Fake!’ True, a few experts now say they had their doubts, but it was only when the NGV proudly loaned its ‘van Gogh’ to Scotland’s Dean Gallery last year that the painting was denounced. Three British critics took one look at it and snorted… Even then, there were some back in Melbourne who couldn’t accept the evidence of their own eyes, as ABC Television’s 7.30 Report found:
“‘Two of the critics include Michael Daley from ArtWatch UK and Times art critic Frank Whitford. But Robyn Sloggett [an art authentication expert at Melbourne University] has questioned their expertise. ROBYN SLOGGETT: I don’t think either of them are Van Gogh experts, certainly not known to be such…[Director of the National Gallery of Victoria] DR GERARD VAUGHAN: It is a slightly offbeat picture. It doesn’t fit into the natural progression of Van Gogh’s work at that time because it was a moment in late ’86 and into early 1887 where he was experimenting with two or three different styles. In many ways, this is slipping back into his earlier realist style of the mid 1880s where he concentrates and uses these earthier ochre colours. It is a transitional picture.’”
“Conceived at special moments” and “sometimes repeating, sometimes anticipating themselves” are commonplace apologias for disqualifying incongruities in upgrades. In 1997 and 2000 the National Gallery claimed its Rubens Samson and Delilah did not look like any other Rubens in the gallery because it was “the only work in this collection typical of the artist when he had returned from Italy in 1608”. In truth the painting was unlike the (secure) one that immediately preceded it and unlike the (secure) one that immediately followed. If a Rubens, it would be the only one on which he employed flat brushes and painted finger tips with rectangular highlights. During ABC Television’s 7 August 2006 programme (“NGV’s Van Gogh Labelled a fake”), James Mollison, a former NGV director said: “This picture has been doubted by people very often.”
The upshot of the controversy was that the NGV director announced that such was the gallery’s confidence that the painting would be submitted (voluntarily) to full technical examination at the Van Gogh Museum. A year later the Herald Sun reported the attribution’s demise at the Van Gogh Museum:
“The Dutch team used X-radiograph, digital photographs, light microscopy and paint and thread analysis. Among conclusions were: THE work’s ground layer of white paint is not found in Van Gogh’s Antwerp and Paris works. ITS use of pure ochre is not found in other Van Gogh work. THE portrait shows just the top of the man’s shoulders. Van Gogh usually showed more of the clothes. “A COMBINATION of a fairly coarse and detailed painting style”, with more detail in the mouth, eyes, skin and beard than Van Gogh used. NO reference to the portrait or the sitter in Van Gogh’s extensive letters. The experts also noted no record of the work could be found before 1928, when it appeared at Berlin’s Galerie Goldschmidt and Co.”
The Rubens Samson and Delilah emerged in Germany the following year at Van Diemen and Benedict where it was offered as a Honthorst before being upgraded by Ludwig Burchard. Previously it had been attributed to Jan van den Hoecke, a follower of Rubens. Burchard had recently upgraded the supposed Rubens ink sketch design for the Samson and Delilah (see Art’s Toxic Assets and a Crisis of Connoisseurship ~ Part II: Paper – sometimes photographic – Fakes and the Demise of the Educated Eye ).
The Newly Upgraded Filippino Lippi
Above, Fig. 9. At first glance the awakened “Filippino Lippi” (above right) seems more plausible than the new Van Gogh drawings – especially when linked to a work attributed to the painter at the North Carolina Museum of Art (above left). In terms of palette, condition and design the two seem as peas in a pod but this closely related pair triggers no recollections of anything similar in the artist’s oeuvre. If their strikingly common format suggests original incorporation in a larger work, disjunctive variations in their parapet walls and stone inscription tablets dispels the possibility. Most inexplicably of all, the new upgrade is incongruously modernist in its emphatic planar and ‘on-the-picture-surface’ geometrical vocabulary.
Above, Fig. 10. In 1901 the painting of Saints Uraldus and Fridianus was sold (not as a Philippino Lippi but as a Masaccio) to an English aristocrat, the Earl of Ashburnham. As with the recently proposed Haddo House Raphael (Fig. 10 above), there is little on the panel’s back other than a label in English for an exhibition of “Early Italian Art” (Fig. 10 top). For the Carolina Saint Donatus, the museum offers only a date – “circa 1490” – and the identity of the picture’s donor, the Samuel H. Kress Foundation. Such lacunae are perplexing because Filippino Lippi is a well-chronicled artist whose securely attributed works might easily be brought into direct comparison with the two more recent attributions.
Above, Fig. 11. The backs of attribution upgrades often prove problematic, and none was more so than the small panel “discovered” as a Duccio Madonna and Child (above right) in 1904 after having been bought in an antiques shop in Italy. It was then rarely seen until bought with fanfare (but no technical examinations) for $50m in 2004 by the Metropolitan Museum of Art, New York, in a blind “treaty” sale conducted by an auction house among a few leading museums shortly after the picture was withdrawn from an imminent comparative exhibition of Duccio and his followers that would have introduced the painting to many scholars for the first time and in an instructive context. That withdrawal – despite the painting’s inclusion in the catalogue – might have been made out of fear of repeating the demise of the owners’ second Duccio, as described below.
The back of the tiny picture had been cradled with no fewer than eight mahogany bars and when these were later removed at the Met. a hand-written ascription to Duccio’s pupil “Segna” was found on the bare poplar wood from which painted work had been stripped. The Met Duccio contained modern wire nails, a fact not acknowledged in the museum’s post-purchase technical examination reports. When we asked after the antiquity of the nails the museum claimed they had been inserted as repairs after the panel had been cradled in the 1930s. As “proof” of that unsupported chronology it was said that one of the nails had entered one of the mahogany bars. However, as we pointed out, the head of that particular nail had been visible on the front of the frame throughout all of picture’s photographically recorded history and, while some nail heads were visible most were not and therefore had been applied before the (now heavily distressed) frame was gessoed and gilded. Thus, the panel arrived in the world at the beginning of the 20th century with modern nails intersecting a cradle that concealed an awkward ascription on a stripped-down back.
Above, Fig 12. A face painted in the 14th century by a follower of Duccio (identified by Pèleo Bacci as Segna) is shown above to the right of the face of the Met’s Duccio as it was before restorations established the blue of the Virgin’s mantle to be azurite, not the requisite ultramarine. No one ever suggested that the painting on the right was by Duccio and no one judged the Met’s picture an autograph Duccio before Bernard Berenson’s wife (Mary) in 1904 with the support of Berenson’s protégé Frederic Mason Perkins. An earlier suggestion had been that it was a work of Sano di Pietro, as Frances Vieta discovered in researches at the Frick Library, New York, that were kindly made available to us.
In 1933 Perkins attributed a second Madonna and Child to Duccio and persuaded the then owner of the Met.’s Ducio (the Belgian collector, Adolphe Stoclet) to buy it. In 1989 that Duccio was loaned to the Cleveland Museum of Art and was there identified on technical examination by Gianni Mazzoni as a fake by Icilio Federico Joni who ran a forgery factory fronted by middlemen, one of whom was Berenson’s protégé Frederic Mason Perkins.
Above, Fig. 13. A cult of Supreme Art Historical Importance was activated around the Met. Duccio and part of this mythology rested on the picture’s supposedly miraculously well-preserved, little-restored, condition. Comparison of the photographs above showing its present state (right) and an earlier state (left) discloses how extensively the work has been repainted – note the altered design of the dominant eye, and the extensive reworking of the veil. The potentially falsifying nature of restorations when determining attributions remains a conspicuously under-examined area – as does the extent and nature of repainting on stripped-down “sleepers”. (But see “A restorer’s aim – The fine line between retouching and forgery”. For a fuller account of the Met.’s Duccio difficulties, see Michael Daley: “Buyer Beware”; “Good Buy Duccio?” and “Toxic Attributions?” in the Jackdaw magazine issues of Nov/Dec. 2008, Jan/Feb. 2009, and March/April 2009.)
The Newly Upgraded Filippino Lippi (continued)
Above, Fig. 14. With the two small “Filippino Lippi” pictures at Fig. 9 and below, top, said to have been painted between 1490 to 1494, precise stylistic comparisons can be made with securely attributed works in the oeuvre. What is believed to be Filippino Lippi’s self-portrait above was executed by the artist in 1481-1482 in the Brancacci Chapel, Santa Maria del Carmine, Florence.
Above, Fig. 15. Filippino Lippi’s Apparition of the Virgin to St Bernard of 1480-86 was said by Bernard Berenson (in his 1938 revised Drawings of the Florentine Painters) to comprise “Filippino’s masterpiece, the last picture in which he is still a pure Quattrocentist, in which there is no sense of the Baroque.” Is it conceivable that some years later this artist painted the two small pictures shown here above the Apparition? Berenson reports that Filippino went on to betray excesses, not to purge and severely abstract his pictorial vocabulary: “Filippino’s Baroque, however had little in common with the qualities of the genuine [Baroque] style, and much with its worst vices. These were the sins of extravagance, of wantonness – the vulgarity of the newly enriched, who feel life is enhanced by the mere act of showy spending.”
Above, Fig. 16. At the top we see how Filippino Lippi painted books before 1486 in his Apparition of the Virgin to St Bernard and before his lapse into Baroque excesses. In this secure work we not only see great technical accomplishment but a fascination with the very means by which books were stitched together in assembled folded sections. Is it conceivable that after this tour de force celebration of the book binder’s craft skills Filippino should have been satisfied with the out-of-perspective simplifications of books in the Saint Uraldus? While the opened book has been painted in utter ignorance of book binding methods, the ochre coloured book at the bottom left of the pile has managed to anticipate to a remarkable degree the appearance of a neat modern machine-bound book.
Above, Fig. 17. Again, does the chasm of technique and sophistication in this further comparison from the Apparition and the Saint Uraldus not strain credulity at claims of a common author?
Above, Fig. 18. By 1493-94 the artist had completed his Madonna and Child with St Catherine of Alexandria and St Martin of Tours as above and we see precisely the over-elaboration Berenson castigated as Filippino’s squandering “like a nabob with a heady disorderliness all the decorative motives which the heritage of antiquity, the hard earnings of his precursors, and his own fancy had put into his hands.”
Above, Fig. 19. How conceivable is it that Filippino might, at the same short period, have made two so diverse treatments of a man parting drapery with an advancing left arm as in these two paintings? In the one the “Blanket-like drapery dear to Filippino” (in Berenson’s term), curves, twists and folds naturally across the body, while in the other it moves as if fabricated by a former sheet metal worker with little regard for any underlying body, or even for the means by which the glimpsed parts of the (wildly varying) decorative border of the cope might ever have been united as woven material. Why the arbitrary, asymmetrical placement of indeterminate embroidered decorations on the cope’s border? What holds the cope together? Is it a giant garnet or ruby, or a small tambourine? Where else in Filippino might we encounter such flattening abstractions and lax indeterminacy of depiction?
Above, Fig. 20. If the logic and treatment of Saint Donatus’ cope border (above, left) seems plausible and suitably understated, what might have carried the same artist to the Byzantine and conceptually irresolvable twin conundrums of the cope border as encountered on Saint Uraldus (above right)? What accounts for the very different depictions of the inscribed tablets on the parapet wall? If that of Saint Donatus is somewhat overly monumental and set uncomfortably close to the top of the parapet, at least it is sculpturally resolved and satisfactorily symmetrical along its horizontal axis with its twin decorative “butterfly wings” termini. Why, then, would the twinned tablets of Saints Uraldus and Fridianus meet in the middle with single butterfly-wing termini while leaving blank endings at the outer edges of the picture’s composition? Why are these two inscribed tablets skimped and devoid of projection when the saints above are greatly more dynamic and humanly engaged – almost as if in anticipation of Raphael’s later depicted dialogue between Aristotle and Plato?
Below, Fig. 21. What theological reading of Saint Uraldus’ life prompted the vast frilled neck lizard-like display of the cope’s pink lining below? If intentionally “Baroque” in its explosive ostentation and theatrical impact, why, then, its implausible combining with a geometric severity of draperies that are more snapped than folded?
With such bizarrely anomalous visual constructs, might it not be prudent to consider the waking “Filippino Lippi” sleeper as a possible product of the late 19th and early 20th century Italian forgeries boom that was tailor-made for British and American collectors? We know that many skilful artists were employed in that trade because when the Italian Government proposed stringent export taxes in 1903 to stem the country’s out-flow of art treasures, the Florentine art dealers association petitioned that the new laws would throttle the large and thriving trade in forged art and antiquities for foreign collectors. (Where did all those often excellent works go?)
At the December 2015 ArtWatch UK/LSE Law/NY Center for Art Law conference Art, Law and Crises of Connoisseurship (the proceedings of which will be published shortly), Professor Charles Hope pointed out how effectively 20th century scholarship had winnowed previously overblown numbers of Titians, Raphaels and such. Markets are good things and the London art market has long been a very good (much envied in Europe) force for Britain, but there are developing dangers. If perceptions were to grow that previously downgraded works are being systematically rehabilitated through “sleeper-discovery” mechanisms at a time when leading houses are fighting to the death for pole position on market share, confidence in the lots on offer might evaporate. Already, certain external structural changes are weakening the London market’s traditional and much-valued symbiotic relationship with disinterested scholarship. Increasing litigation by owners against dissenting independent scholars suppresses debate and frank expert appraisal. In a paper at our conference (“Throwing the baby out with the bath water – the Demise of Connoisseurship since the 1980s”), Brian Allen, former director of studies at the Mellon Centre, warned that recent changes of philosophy and views on connoisseurship in the academic world are greatly reducing the traditionally available body of disinterested academic expertise that counterbalances purely commercial interests:
“In my own field of British art the number of so-called ‘experts’ has now diminished alarmingly as the older generation dies off not to be replaced. It seems extraordinary to me that major artists such as Stubbs, Wright of Derby and Sir Thomas Lawrence, to name but three, don’t have an acknowledged expert to whom one can turn for a reasonably reliable, independent opinion. And this has also certainly happened in other specialist fields… Younger scholars nowadays, especially those in the universities, have almost no contact whatsoever with the art trade compared to fifty years ago. Yet for many years it was perfectly possible for the two worlds to co-exist harmoniously.”

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.

Appendix A
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.”

Appendix B
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.”

Appendix D
Carlo Pedretti
“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’”.
