BEIJING, Feb 16 (Xinhuanet) -- New scientific findings prove that Renaissance artist Leonardo da Vinci did paint an earlier and much younger version of his master-piece Mona Lisa, said Swiss-based art experts.
Art experts claimed that Isleworth Mona Lisa, unearthed last year, which shows a significantly younger subject, may be several years older than its more famous counterpart.
Mona Lisa, which has been on display in the Louvre in Paris for three centuries, has long been regarded as the only one painted by the Italian artist.
Carbon dating placed the creation of the painting in the correct era, refuting claims that it was a later copy of the main painting, which was created in around 1516.
Geometric analysis has shown that painting matches the proportions da Vinci depicted in his human forms. The results may help convince other experts who were sceptical when the painting was unveiled in Geneva last year, after it had been kept in a Swiss bank vault for four decades.
