In Greek mythology, Pheres , son of Cretheus and Tyro and brother of Aeson and Amythaon, was the founder of Pherae in Thessaly. He fled there from Iolcus after his half-brother, Pelias, seized the throne. He married Periclymene, daughter of Minyas, and became the father of Admetus, Lycurgus, Eidomene (wife of Amythaon or Bias) and Periopis (possible mother of Patroclus). Of them Admetus was the husband of the famous Alcestis, who died in his stead and was rescued by Heracles, while Pheres, despite his old age, would not do the same for his son.
