a painter and statuary, who flourished in the 107th Olympiad (B. C. 352). His most noted pictures were the following: Father Liber; Tragedy and Comedy; Semiramis passing from the state of a handmaid to that of a queen, with an old woman carrying torches before her; in this picture the modesty of the new bride was admirably depicted. He is ranked by Pliny and Cicero with the greatest painters of Greece, Apelles, Melanthius, and Nicomachus. (Plin. Nat. 34.8. s. 19; 35.7. s. 32; 10. s. 36.9.) The picture in the Vatican, known as "the Aldobrandini Marriage," is supposed by some to be a copy from the " Bride" of Echion. (Kugler, Handbuch d. Kunstgesch. p. 236; Müller, Arch. d. Kunst, § 1403.) Hirt supposes that the name of the painter of Alexander's marriage, whom Lucian praises so highly, AETION, is a corruption of Echion. (Gesch. d. Bild. Künste, pp. 265-268.)
