Persephone was the beautiful daughter of Zeus, king of the gods, and Demeter, goddess of agriculture. Persephone also goes by the name of Kore or Cora, and she is thought of as the maiden goddess of spring and grain. In the most popular myth of Persephone, she's the unwilling wife of Hades, lord of the underworld, and must spend a few months out of the year with him in the land of the dead. Nothing grows on earth when Persephone is among the dead, because Demeter is so sad about her daughter's fate. And so the myth of Persephone is used to explain the seasons.
