Leonardo Da Vinci's 500-year-old Renaissance masterpiece has long been steeped in mystery, and even today the true identity of the woman with the alluring smile still far from certain.
Now members of Italy's National Committee for Cultural Heritage have revealed that by magnifying high resolution images of the Mona Lisa's eyes letters and numbers can be seen.
"To the naked the symbols are not visible but with a magnifying glass they can clearly be seen," said Silvano Vinceti, president of the Committee.
He said: "It is very difficult to make them out clearly but they appear to be the letters CE or it could be the letter B - you have to remember the picture is almost 500 years old so it is not as sharp and clear as when first painted.
"While in the arch of the bridge in the background the number 72 can be seen, or it could be an L and the number 2."
