A team of researchers in Italy has begun looking for the remains of the woman long thought to be the model for Leonardo Da Vinci's famous painting, the Mona Lisa.
They hope to find the skull of the woman, Lisa Gheradini, buried in the Saint Ursula convent in Florence by using a ground-penetrating radar device.
The archaeologists' ultimate aim is to find enough skull fragments to be able to reconstruct her face, enabling a comparison to be made with the Mona Lisa.
The identity of the subject of the Mona Lisa has remained one of the greatest mysteries of the art world for nearly five centuries.
