After a decade of studying the acclaimed Leonardo da Vinci portrait and using groundbreaking techniques to scan the painting, Pascal Cotte claims to have found the image of another woman beneath layers of pigment.
And he argues that this hidden portrait is the likeness of the Florentine merchant’s wife long suspected to be Leonardo’s model for Mona Lisa. The study shows evidence that Leonardo first painted the portrait of a different woman, he says.
Mr Cotte believes the marks discovered show the features of the real Lisa Gherardini, widely thought by experts as the subject of the Mona Lisa, and that the finished work is of a different woman.
“When I finished the reconstruction of Lisa Gherardini, I was in front of the portrait and she is totally different to Mona Lisa today. This is not the same woman,” Mr Cotte says in the BBC2 documentary, Secrets of the Mona Lisa, to be to be broadcast on 9 December.
Mr Cotte and art historian Andrew Graham-Dixon, who presents the documentary, labelled the discovery as groundbreaking. Yet, art historians and experts said too much could be read into such technical images, and the digital recreation of the original portrait was unreliable.
Leonardo painted the portrait between 1503 and 1517. It is believed he was initially commissioned by Lisa’s husband, but failed to deliver the painting and later reworked it.
Mr Cotte has pioneered the layer amplification method, which uses 13 different wavelengths of light bounced off the pigment to produce images throughout different layers of the painting. “My scientific imagery technique... reveals secrets that have remained hidden for 500 years,” he says.
Mr Cotte believes he has found three different portraits underneath the finished work. One is an early study of a head and another is a Madonna-style portrait. The third, he believes, is the original portrait of Lisa Gherardini..
Martin Kemp, emeritus professor of the history of art at the University of Oxford, said: “It’s extraordinary and notable data and perfectly clear the picture has undergone substantial changes. Leonardo did that to other paintings; he was a remorseless fiddler.”
But he added: “That there are two or three quasi-finished pictures under there that you could find if you peeled back the layers, is not really supportable. Leonardo’s process of composing pictures was very fluid. Things came and went.
One anonymous art historian said: “The scientist has been spending too much time on Photoshop.”
