Mona Lisa revealed

The real identity of the Mona Lisa has been revealed, a group of German academics says. Experts at the Heidelberg University library found notes scribbled in the margins of a book, dated October 1503, that they say confirm what many art historians have long thought to be true: Lisa Gherardini, the wife of the wealthy Florentine merchant Francesco del Giocondo, was the model for Leonardo da Vinci's legendary portrait, Reuters reports.
