In Hesiod’s *Theogony*, after Perseus beheads Medusa, Chrysaor and the horse Pegasus spring from her neck. Chrysaor, “he of the golden sword,” then unites with Callirhoe, daughter of Oceanus, and she bears Geryon—three-headed (or three-bodied) and mighty. Hesiod places him on Erytheia amid the Ocean stream, where he keeps cattle that Orthrus the two-headed hound and the herdsman Eurytion will later guard.
The notice is genealogical rather than episodic: Geryon’s power and western seat are explained by Oceanid motherhood and Gorgon-sired fatherhood, preparing the later Heraclean cattle-raid without narrating it. Catalogue this birth apart from the labor and from Medusa’s death.
