What name did the Ancient Greeks give to the Sun?

The ancient Greeks personified the sun as a handsome god named Helios. His astronomical pedigree was impeccable: He was the son of the Titan Hyperion and the Titaness Theia. Helios was also the brother of Selene, the goddess of the Moon, and Eos, the goddess of the dawn. Said to be crowned with a radiant burst of sunbeams, Helios daily drove his chariot of the sun, drawn by what the ancient Greek poet Pindar called “fire-breathing horses,” across the sky. Along the way, he delivered sunshine around the world. Helios repeated his appointed rounds each morning after his sister Eos announced the new dawn.
