I cannot speak to broader trends among art curators but I think it is a mistake to blame broad trends in the field of art history for the existence of forgeries. They have always been present, and likely always will be in some form. Failing to conduct a rigorous study of the history of an object should have course be criticized, but that kind of unfortunate mistake should be contrasted when an object which might have a good history free of the potential of looting. This happens for antiquities, works of art, and many other objects. Some forgeries are made maliciously to fool, other works of art which are inauthentic appear absent any wrongdoing of the creator.
Scott Reyburn aptly summarizes the range of possibilities with respect to the controversial work of art known as “La Bella Principessa” in his report for the New York Times:
By various accounts, then, it would seem that “La Bella Principessa” is either a real Leonardo worth tens of millions; a 19th-century Italian Renaissance style drawing worth tens of thousands; or a modern fake worth hardly anything at all.
The Sunday Times has published a report that claims Shaun Greenhalgh, a prolific art forger who has fooled the Art Institute Chicago, the British Museum, and countless others may be the creator of this work. He claims he created the work in the 1970s, depicting a “bossy” supermarket clerk named Alison.
Doubts should now increase as to whether this is an authentic Leonardo da Vinci. It was purchased by a Canadian, Peter Silverman, who has been trying to demonstrate the authenticity of the work. It seems the work was made on vellum, but may have been done on the wrong side. The art critic Waldemar Januszczak, part of a consortium publishing a limited run of Greenhalgh’s memoirs, writes in the Sunday Times that Greenhalgh “bought an old land deed that had been written on vellum, and finding the ‘good’ side to be too ink stained to use turned it over and drew on the rough side instead, as Leonardo would never have done”.
For now Silverman will keep the work of art at the Geneva freeport. In an attempt to burnish the reputation of the work, he claims he will offer 10,000 pounds to Greenhalgh if he could reproduce the work on vellum, and criticized Januszczak as “shameless”.
