This combination of images shows an undated self portrait of Leonardo Da Vinci, left, and the Mona Lisa. A group of Italian scientists is seeking permission from French authorities to dig up Leonardo Da Vinci’s body to conduct carbon and DNA testing in order to solve the mysteries of how he died, and whether the Mona Lisa was actually a self-portrait in disguise.
