You may not know the name “Lisa Gherardini Del Giocondo,” but we’re sure you’ve seen her picture. No, she isn’t the latest Jersey Shore cast member — she was, according to the vast majority of art historians, the model who posed for the most famous portrait of all time, Leonardo da Vinci’s Mona Lisa. And, as LiveScience reports, researchers may be very close to locating the crypt where Del Giocondo was buried after her death in 1542. A largely intact skull, io9 notes, would enable the creation of a computer-simulated image of what Del Giocondo really looked like. Sadly, nothing short of successful communication with the spirit world will reveal WTF is going on with that look on Mona Lisa‘s face.
