An Italian researcher has sparked new controversy over the world's most famous painting by claiming Leonardo da Vinci painted tiny letters into the eyes of the Mona Lisa which may finally reveal the disputed identity of his model.
To arrive at a theory worthy of The Da Vinci Code, Dan Brown's 2003 bestseller, researcher Silvano Vinceti avoided the Mona Lisa's enigmatic smile and instead gazed deep into her eyes with the help of high-resolution images.
"Invisible to the naked eye and painted in black on green-brown are the letters LV in her right pupil, obviously Leonardo's initials, but it is what is in her left pupil that is far more interesting," said Vinceti, the chairman of the Italian national committee for cultural heritage.
Vinceti said that the letters B or S, or possibly the initials CE, were discernible, a vital clue to identifying the model who sat for the Renaissance artist. She has often been named as Lisa Gherardini, the wife of a Florentine merchant, but Vinceti disagreed, claiming Leonardo painted the Mona Lisa in Milan. He said he would announce his conclusions next month.
