Poeas was one of the Argonauts and a friend of Herakles. As an Argonaut, Poeas is identified as the greatest archer of the group. When facing Talos the Bronze Giant who guarded island where the Golden Fleece was held after Medea had drugged Talos it was Poeas who killed the Metal Giant by shooting a poison arrow in the heel. There is however another account where it was Kastor and Polydeukes who worked with Medea to kill Talos. Poeas was also the king of Meliboea Thessaly.
