Red-figured krater depicting Helios in his chariot, 5th century B.C.
London, British Museum, inv. GR 1867,0508.1133

Apollo-Helios, commanding a chariot drawn by four swift horses, pulls the Sun across the sky. The god emerges from the eastern ocean every morning and plunges into the western sea every evening, disappearing beneath the Earth where he spends the night at rest.
