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 representing the marriage of Alexander and Roxana. He is said to have exhibited it at the Olympic games, and by it so to have won the favour of the president that he gave him his daughter in marriage. Through a misunderstanding of the words of Lucian, Aetion has been supposed to belong to the age of the Antonines; but there can be little doubt that he was a contemporary of Alexander and of Apelles (Brunn, Geschichte der griechischen Künstler, ii. p. 243). Pliny gives his date as 350 B.C.
