In Greek religion and mythology, Helios is the god and personification of the Sun. He is sometimes called a Titan and is responsible for bringing light to the world as the god of the sun. Helios rode a chariot daily from east to west across the sky and sailed around the world at night. He is the offspring of the Titans Hyperion and Theia, and his sisters were Selene (the Moon) and Eos (Dawn). Helios is also the father of Phaethon, whose mother was Clymene. In classical Greece, Helios was especially worshipped in Rhodes, where he was regarded as the chief god. His worship spread as he became increasingly identified with other deities, often under Eastern influence. Though Helios was a relatively minor deity in Classical Greece, his worship grew more prominent in late antiquity thanks to his identification with several major solar divinities of the Roman period, particularly Apollo and Sol.
