The myth of Persephone explains the changing of the seasons. Persephone, the daughter of Demeter, is kidnapped by Hades and taken to live in the underworld as his wife. Her mother Demeter's grief over her missing daughter causes plants to stop growing. Eventually, Zeus intervenes and allows Persephone to return to her mother, but because Persephone ate food in the underworld, she is bound to return there for part of each year, during which time Demeter grieves, causing winter.
