Persephone is the Goddess of the Underworld, wife of Hades.
But it wasnt always this way ... originally a flower maiden and daughter of Demeter Goddess of Harvest ... her story unfolds with her descension into the underworld and her seduction with pomegranate seeds.
Persephone spends equal parts of the year above and below and so gives rise to the seasons. The life cycle of plants and harvest.
