Helios, << HEE lee os, >> was the sun and god of the sun in Greek mythology. His sisters were Selene (the moon) and Eos (dawn). The Greeks believed Helios, accompanied by Eos, drove a four-horse chariot across the sky each day. Each evening, a huge golden cup brought him back to his palace in the east on the river Oceanus, which encircled the world. His daily journeys made him an all-seeing god, and the Greeks often called upon him to witness their oaths. The island of Rhodes, in the Aegean Sea, was sacred to Helios, and a famous statue of him stood there.
