Researcher Silvia Gori works inside the Sant'Orsola monastery in Florence, Italy, Tuesday, July 24, 2012. Archeologists found a skeleton buried inside the monastery that could belong to Lisa Gherardini, the first model of Leonardo da Vinci's 'Mona Lisa' painting. Lisa Gherardini was the wife of a silk merchant called Francesco del Giocondo (in fact, Italians refer to the Mona Lisa as the "Gioconda"). According to art historian Giorgio Vasari, del Giocondo commissioned Leonardo to paint a portrait of his wife. Leonardo took about 15 years to complete what was to become one of the most famous paintings in the world. When her husband died, Lisa retired to the Sant'Orsola convent where she died age 63, on the 5th of July 1542.
