Eos is the goddess of the dawn and a Titan in Greek mythology. She is the daughter of Hyperion and Theia.
She is the sister of Helios, the sun god, and Selene, the moon goddess.
Eos leaves her home, which was at the edge of ocean, every morning to wake her brother, Helios. She opens the gates of heaven so that Helios can ride his chariot across the sky each day.
