Zeus lies in Ceres' bosom

Zeus was the lord of the gods in Greek mythology and is thus identified with masculine and political power and the sky and heavens. He was married to the goddess Hera, who was his sister, but had numerous affairs with other gods and mortals. He had a child by another sister, Demeter (called by the Romans, Ceres), the goddess of agriculture. That child was Persephone, who became identified with the changing of the seasons.
