The name Helios originates from the Greek word for 'sun'. In Greek mythology, Helios is the god who personifies the Sun, depicted as a radiant youth driving a horse-drawn chariot across the sky each day. He is the son of the Titans Hyperion and Theia, and the brother of Selene (the Moon) and Eos (the Dawn). Helios was a guardian of oaths and the god of sight, and his worship became more prominent in late antiquity due to his identification with major solar divinities like Apollo and Sol.
