Eurytus and Cteatus

Sources present variant origins. Genealogical summaries group the brothers under the matronymic Moliones (children of Molione); some traditions give their father as Actor, while other local traditions claim Poseidon as father. A poetic tradition cited by Athenaeus (Ibycus) portrays them as miracously born from a silver egg and styled as 'white-horsed youths.' The conjoined-body description (one body with two heads, four arms and four legs) appears in later summaries of the tradition; Homeric epic is silent on that marvellous physicality.

Accounts diverge. Later summaries describe a striking conjoined form—one body with two heads, four arms and four legs—presenting them as a marvel within the heroic catalogue. Earlier or different sources do not mention this anomaly: Homeric references make no note of conjoinment and treat them as conventional warriors, while Ibycus (via Athenaeus) uses the image of 'white-horsed youths' and a silver-egg birth, a poetic motif aligning them with twin-hero imagery rather than the conjoined marvel.

In the extant narratives they are chiefly martial figures: accomplished warriors and leaders who fought on expeditions to Neleus and the Pylians and who were involved in the conflict surrounding King Augeas of Elis. They were recruited by Augeas and later attacked Heracles, who killed them outside Cleonae. Athenaeus' citation of Ibycus preserves a poetic image that parallels other divine twin motifs (white-horsed, egg-birth), but the surviving excerpts do not attribute explicit supernatural powers beyond notable birth-images and martial prowess.
