Highly magnified images of the painting reportedly reveal tiny letters embedded into the "Mona Lisa's" eyes, reports the U.K.'s Guardian .
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.
"It is very difficult to make them out clearly, but they appear to be the letters CE, or it could be the letter B," Vinceti added.
In what could be a chapter out of Dan Brown's book (and the 2006 film) "The Da Vinci Code," more mysterious letters and numbers are found on the "Mona Lisa." Vinceti believes these are deliberate hints as to the actual identity of the model who posed for da Vinci's masterpiece, a mystery that has puzzled art historians for centuries.
