Plinius: Historia Naturalis, Buch XXXV, Kap. 43 - Zum Ursprung der Malerei.
“Butades, a potter of Sicyon, was the first who invented, at Corinth, the art of modelling portraits in the earth which he used in his trade. It was through his daughter that he made the discovery; who, being deeply in love with a young man about to depart on a long journey, traced the profile of his face, as thrown upon the wall by the light of the lamp.”
