Eurynome (yōrĭnˈəmē) [key], in Greek mythology, daughter of Oceanus and Tethys and mother, by Zeus, of the Graces. In the mythology of the Pelasgians, an aboriginal non-Greek people living in Greece before the Mycenaean period, she rose alone out of chaos and separated the earth from the sky. She created the great serpent Ophion and mated with him. Thus she gave birth to all existing things.
