Detail of the ancient Greek Black-Figure “Sophilos Dinos” (wine-bowl), ca. 580-570 BCE depicting guests attending the wedding of Thetis and Peleus, future parents of Achilles. Athena and Artemis are seen riding in the chariot, followed by Thetis’ grandfather, the fish-tailed sea-god Okeanos, his wife Tethys, and Eileithyia, goddess of childbirth. Hephaistos brings up the rear, seated side-saddle on a mule.
