Paeon of Elis

Paeon or Paion (Ancient Greek: Παίων, gen.: Παίονος), in Greek mythology, was an Elean prince as son of King Endymion, and brother of Epeius, Aetolus, Eurycyda and possibly Naxos. From him, the district of Paeonia, on the Axius river in Macedonia, was believed to have derived its name.
