Caravaggio painting: A dusty painting discovered in the attic of a house near Toulouse, France, turned out to be the subject of a major art discovery in 2014. French art expert Eric Turquin identified the painting as a lost work by Italian master Caravaggio. The artwork depicts the biblical story of Judith beheading Holofernes. CNN reported that the painting could be worth more than $100 million if its attribution to Caravaggio was accepted.
