In Greek mythology, Panopeus (Ancient Greek: Πανοπεύς) was a son of Phocus by Asteria or Asterodia, and twin brother of Crisus.
The two brothers were so inimical towards each other that they began fighting while still in their mother's womb, just like Proetus and Acrisius did.
[1] Panopeus participated in Amphitryon's campaign against the Taphians and the Teleboans,[2] and swore by the names of Athena and Ares not to lay his hand on any part of the booty.
He, however, broke his oath; as punishment, his son Epeius became unwarlike, but still a good boxer and a skilled mechanic.
[4] Panopeus was renowned as a skilled hunter[5] and took part in the Calydonian boar hunt.
