AETION or EETION, a Greek painter, mentioned by Cicero, Pliny, and Lucian. His most noted work, described in detail by Lucian (Herodotus or Eetion, 5), was a picture repre senting the marriage of Alexander and R.oxana. Through a mis understanding of the words of Lucian, Aetion has been supposed to belong to the age of Antonines; but there can be little doubt that he was a contemporary of Alexander and of Apelles (Brunn, Geschichte der griechischen Kiinstler, ii. p. 243). Pliny gives his date as 350 B.C.
