1. Mona Lisa
Mona Lisa is probably the most famous painting in the human history. Created in 1506, it is hung in the Louvre and attracts hundreds of people every day who want to see the glance the follows you wherever you go. For quite some times nobody knew who the soft glance belonged to, until in 2005 German Scholars discovered a handwritten comment in the Heidelberg manuscript that identified her as Lisa del Giocondo (née Gherardini), a noblewoman from Florence. Apparently, the portrait was commissioned by her merchant husband, Francesco Giocondo.
