WE’LL FINALLY DISCOVER WHO THE MONA LISA WAS.

The identity of Mona Lisa has long been a mystery. Some think Leonardo da Vinci modeled his masterpiece on his mother; others, on a secret male lover. In fact, one art historian identified her just a few decades after the painting was completed as Lisa Gherardini del Giocondo, the wife of a wealthy cloth merchant who commissioned the piece to a then-broke da Vinci. (The fact that the artist named his work La Gioconda was a big clue.) Now, thanks to radiocarbon dating, this hunch may finally be confirmed. Researchers believe they may have found Gherardini’s remains in a convent in Florence. If the carbon-14 tests confirm that it’s her, scientists will also do DNA tests to determine the color of her eyes, skin, and hair. With that information, they’ll be able to confirm if she is the world’s most famous half-smiler.
