A daughter of Zeus and Demeter, Persephone is both the goddess of the underworld as well as grain. The beautiful Persephone was stolen by Hades to be his wife. Demeter, with her child missing, roamed the earth looking for her, abandoning all her other duties. Time passed, the crops would not grow, and humans and animals began to starve. Seeing this, Zeus stepped in to fix the situation. He sent Hermes to order Hades to return Persephone. Hades said that he would gladly let her go. As she was leaving, Hades entreated her to eat a pomegranate. When Persephone later told her mother of her experience, Demeter grieved to learn that Persephone had eaten the fruit, for the laws of Hades state that Persephone then must return for good! Demeter refused to let her daughter go, so Zeus reached an agreement: Persephone would stay with Hades for one-third of the year at a time (which would become winter), and with Demeter for the rest.
