Eos was the Titan Goddess of the dawn and had two siblings; Helios, the God of the Sun, and Selene, the Goddess of the Moon. She was married to Astraeus, God of the Dusk, and between them all they controlled the rise and fall of daytime in the mortal and immortal realms.

“Theia yielded to Hyperion’s love and gave birth

To great Helios and bright Selene and Eos,

Who brings light to all the mortals of this earth

And to the immortal gods who rule the wide sky.”

-Hesiod’s Theonogy
