Mermerus and Pheres

In Greek mythology, Mermerus (Μέρμερος, Mérmeros; Mermerus) and Pheres (Φέρης, Phéres, modern pronunciation Féris; Pheres) were the sons of Jason and Medea. They were killed either by the Corinthians or by Medea, for reasons that vary depending on the rendition. In one account, Mermerus was killed by a lioness while hunting.
