In the beginning, Eurynome, the Goddess of All Things, rose naked from Chaos and divided the sea from the sky. By dancing on the waves she set the winds in motion. When she rubbed the north wind between her hands, the great serpent Ophion (1) was created and after he coupled with Eurynome, she, taking the form of a dove, laid the Universal Egg out of which tumbled all things that exist.
She then created seven planetary powers and set a Titan and a Titaness to rule over each. The first human was Pelasgus, who sprang from the soil of Arcadia.
(1) Graves identifies Ophion with the serpent Hemiurge of Hebrew and Egyptian myth.
