Mona Lisa identity debate again

Researchers from Italy have discovered the disputed identity of the model for Leonardo da Vinci's Mona Lisa. Silvano Vinceti, chairman of the Italian national committee for cultural heritage, said the Florence-born Renaissance artist's male apprentice and possible lover Salai was the main inspiration for the picture. This is after having found similarities with the Mona Lisa's nose and mouth against earlier portraits, and close examination revealed an L for Leonardo and an S for Salai.

However, the claim was immediately disputed by experts at the Louvre in Paris, where the painting is on display.

The debate goes on again and again, possibly forever.
