Epeius of Elis

In the mythic genealogies of Elis, Epeius is a son of Endymion. According to the ancient tradition summarized in Pausanias and later epitomes, Endymion set his sons to compete in a footrace at Olympia for succession; Epeius won that race and thus obtained the kingdom of Elis. His reign marks the first application of the ethnonym "Epeans" to the inhabitants of Elis. He married Anaxiroe (daughter of Coronus) and had a daughter, Hyrmine; having no male heir, the throne passed after his death to his brother Aetolus. Sources record variant names for his mother (Asterodia, Chromia, Hyperippe) in different genealogical accounts. Some later or scattered traditions also associate a figure named Epeius with the construction of the Trojan Horse, but that identification is uncertain in the primary Elis genealogical material.

Ancient sources do not provide a physical description of Epeius. He is represented in literary and genealogical records by his social roles and deeds — victorious competitor at Olympia, husband and father, and eponymous founder-king — rather than by bodily detail.

Epeius' attributed 'abilities' are non-magical and social: he is credited with athletic prowess, specifically winning the decisive footrace set by Endymion at Olympia to determine the successor; this athletic victory functions as the basis for his political legitimacy. He is also the dynastic and eponymous founder whose reign gives the people of Elis the name Epeans. Other supernatural powers are not ascribed to him in the cited sources. A separate, uncertain tradition names an Epeius as involved in the crafting of the Trojan Horse, but that association is not established in the primary Elis genealogies summarized by Pausanias and related references.
