In Greek mythology, Amyntor (Ancient Greek: Ἀμύντωρ, translit. Amýntor, lit. 'defender') was the son of Ormenus, and a king of Eleon or Ormenium.[1] Amyntor's son Phoenix, on his mother's urgings, had sex with his father's concubine, Clytia or Phthia. Amyntor, discovering this, called upon the Erinyes to curse him with childlessness. In a later version of the story, Phoenix was falsely accused by Amyntor's mistress and was blinded by his father, but Chiron restored his sight.
Amyntor was also the father of a son Crantor, and a daughter Astydamia. When Amyntor lost a war with Achilles' father Peleus, king of Phthia, Amyntor gave Crantor to Peleus as a pledge of peace. Strabo reports a genealogy for Amyntor which made him the grandson of Cercaphus, the son of Aeolus, and the brother of Euaemon, the father of Eurypylus.
When Amyntor refused Heracles permission to pass through his kingdom, Heracles killed Amyntor and fathered a son Ctesippus, by Astydamia. During the Trojan War, Odysseus received a helmet that had originally belonged to Amyntor.
