a very ancient Greek painter of monochromes, was the first, according to Pliny, who distinguished, in painting, the male from the female, and who " dared to imitate all figures." His invention wits improved upon by Simon of Cleonae. (35.8. s. 34.) Müller (Arch. d. Kunst, § 74) supposes that the distinction was made by a difference of colouring; but Pliny's words seem rather to refer to the drawing of the figure.
