2. A son of Dymas and brother of Hecabe. Apollo assumed the appearance of this Asius, when he wanted to stimulate Hector to fight against Patroclus. (Hom. Il. 16.715, &c.; Eustath. p. 1083.) According to Dictys Cretensis (4.12), Asius was slain by Ajax. There are two more mythical personages of this name, which is also used as a surname of Zeus, from the town of Asos or Oasos in Crete. (Verg. A. 10.123; Tzetz. ad Lycoph. 355; Steph. Byz. s. v. Ἄσος).
