Helios, also Helius in ancient Greek religion and myth, is the Titan God and personification of the Sun, often depicted in art with a radiant crown and driving a horse-drawn chariot through the sky, usually depicted as a handsome young man crowned with the shining aureole of the Sun who drove the chariot of the Sun across the sky each day to Earth-circling Oceanus and through the world-ocean returned to the East at night.

Helios is seen as both a personification of the Sun and the fundamental creative power behind it and as a result is often worshiped as a god of life and creation. Homer described Helios as a god "who gives joy to mortals" and other ancient texts give him the epithet "gracious" , given that he is the source of life and regeneration and associated with the creation of the world.
