Shortly before World War I English art collector, Hugh Blaker, found a portrait now dubbed the Isleworth Mona Lisa in Isleworth, London. For the past 35 years the Zurich-based Mona Lisa Foundation has been working to prove that the painting predates Leonardo da Vinci’s 16th century masterpiece by 11 to 12 years. The experts involved based this conclusion on a series of regression tests, mathematical comparisons, and historical and archival records.
While at least one da Vinci expert is doubtful, the researchers involved in the Mona Lisa Foundation’s project are confident in their claim. Mathematical tests have proven that both of the sitters are in exactly the same place. Such accuracy was typical of da Vinci. Sporting the same enigmatic smiles, the posture, hands, faces, and expressions bear a striking resemblance.
Dissidents, including Oxford art historian Martin Kemp, think that the Isleworth Mona Lisa lacks the subtle details of the original. While the Isleworth Mona Lisa does look like a younger version of the original, the veil, hair, and the translucent layer of the sitter’s dress are lacking in quality.
The Isleworth Mona Lisa turned up in the home of an English nobleman during the late 19th century and was shipped to the United States during the First World War. The painting was subject to analysis in Italy and was eventually taken to Switzerland where it remained in a bank vault for 40 years. The Isleworth Mona Lisa was unveiled by the Foundation on Thursday in Geneva and evidence of the painting’s authenticity was presented at the University of California.
