Researchers have begun a hunt to find the remains of the woman who modelled for Leonardo da Vinci for his famous Mona Lisa masterpiece. They know the whereabouts of the remains of her two daughters and they will use 21st century technology to compare DNA samples to ensure they dig up the correct corpse.
Once they disturb a number of dead bodies, who've been resting in peace for nearly 500 years, they will use computer enhancement, in conjuction with her skull bones, to reconstruct her face.
Forgive me for being simple minded, but, I'm wondering if they thought about just looking at the painting??
