Euaemon (Euaimon)

Euaemon appears as a conventional mythic personal name across multiple Greek narrative traditions rather than originating in a single foundational tale. In Plato's Critias he is named as one of the ten sons of Poseidon and Cleito who become heads of the ten royal houses of Atlantis, each ruling a tenth of the island under the supreme rule of the eldest, Atlas. In Arcadian mythographic tradition he is listed among the fifty sons of King Lycaon who are punished by Zeus for impiety and slain by the god's lightning. In Homeric genealogical contexts he is attested as the father of Eurypylus of Ormenion, a leader in the Trojan War cycle. Separately, Stephanus of Byzantium records a place-name Euaemon (a city) though no further locational details are provided in the surviving excerpt.

The available sources offer no physical description or iconography for Euaemon as an individuated figure. He is attested only as a name in genealogical lists, epic patronymics, and as a toponym; therefore the tradition furnishes no reliable information about appearance or visual attributes.

Classical and later summaries do not attribute supernatural powers or habitual behaviours to Euaemon. His roles in the sources are social and genealogical: as one of Poseidon's sons he is given a titular, civic function (head of a royal house in the Atlantis partition), as one of Lycaon's sons he is counted among impious kin destroyed by divine retribution, and as father of Eurypylus he serves as a patronymic identifier in Homeric epic. No personal agency beyond these narrative and genealogical functions is described in the cited materials.
