Amythaon

In Greek mythology, Amythaon (Ancient Greek: Ἀμυθάων, gen.: Ἀμυθάονος) was prince of Iolcus as the son of King Cretheus and Tyro, daughter of King Salmoneus of Elis. He was the brother of Aeson and Pheres. Amythaon dwelt at Pylos in Messenia, and by Idomene, his niece, or by Aglaia became the father of Bias, Melampus, Aeolia and Perimele. His wife Idomene is sometimes said to be daughter of Abas, king of Argos.

Mythology
According to Pindar, he and several other members of his family went to Iolcus to intercede with Pelias on behalf of Jason. Pausanias mentioned him among those to whom the restoration of the Olympic Games was ascribed. A part of Elis was thought to have been named Amythaonia after him.
