Selene Greek goddess of the moon. Daughter of the Titans Hyperion and Theia. Sister of Helios (sun) and Eos (dawn). Mother of Pandia by Zeus, and of fifty daughters by Endymion. She rode across the sky in a chariot drawn by two white horses. Also a tutelary deity of magicians. Selene was sometimes identified with Artemis as a moon goddess. She became syncretized with Hekate in later Greek mythology. The Romans equated her with Luna.
