InGreek mythology,Eurytus (/ˈjʊərɪtəs/;Ancient Greek: Εὔρυτος) andCteatus (/ˈtiːətəs/; Κτέατος) were twin brothers.

Their mother wasMolione, that's why they were calledMoliones (Μολίονες) orMolionidae (Μολιονίδαι).

They were the sons of eitherActor (whence they were also called Actoridae) orPoseidon and nephew ofAugeas. Eurytus and Cteatus married the twin daughters ofDexamenus,Theraephone andTheronice, respectively.^[1] Their respective sons,Thalpius andAmphimachus, were counted among the Achaean leaders in theTrojan War.^[2]

Greek rhetorician and grammarAthenaeus of Naucratis, in his workDeipnosophistae, Book II, cited that poetIbycus, in hisMelodies, described twins Eurytus and Cteatus as "λευκίππους κόρους" ("white-horsed youths") and said they were born from a silver egg,^[3] - a story that recalls the myth of Greekdivine twinsCastor and Pollux and their motherLeda.^[4]

Greek legend maintains that the brothers were bornconjoined with only one body but two heads, four arms and four legs,^[5] thoughHomer makes no mention of this.

Both brothers went on expeditions of war to theNeleus and thePylians, and later led an army marching against their uncle Augeas at the behest ofHeracles. However after the latter made peace, the brothers attacked Heracles and were subsequently killed by him outsideCleonae.^[6][7]
