Saurias

(Σαυρίας), a very ancient artist of Samos, to whom some ascribed the invention of that first step in the art of drawing, which was called σκιαγραφία, that is, tracing the outline of a shadow. The statement, however, deserves little credit, as it rests on the sole authority of Athenagoras (Athenag. Legat. pro Christ. 14, p. 59, ed. Dechair). [P.S]
