In Greek mythology, Eurynome (Ancient Greek: Εὐρυνόμη) was a daughter of Nisus, king of Megara, and mother of Bellerophon by Poseidon. According to the Hesiodic Catalogue of Women, Athena herself taught the girl handiwork. Sisyphus attempted to drive away her cattle, but ended up winning her as bride for his son Glaucus by the will of Athena. But Zeus had ordained that Sisyphus would not leave behind any progeny, and Eurynome lay instead with Poseidon, giving birth to Bellerophon.
