.Hades did not woo Persephone, he abducted her and took her to his underground kingdom. After much protest, Persephone came to love the cold blooded king of the underworld but her mother, Demeter, was consumed with rage and sorrow. She demonstrated her anger by punishing the earth�s inhabitants with bitter cold and blustering winds. Unless Persephone was returned to her mother�s side, the earth would perish.
Hermes was sent to the house of Hades by Zeus to reason with Hades. He entered the kingdom of Hades and negotiated a compromise between the (usually cold and selfish) Hades and the (usually loving and caring) Demeter. Before Persephone could leave the underworld, Hades gave her a pomegranate seed to eat. By doing this he bound her to himself and his kingdom. When Demeter found out about the trickery she was angry but she was also resigned that there was nothing she could do... her loving daughter was bound to the Lord of the Dead. With no alternative, it was agreed that Persephone would to spend part of the year with her husband, Hades, and part of the year in the sunlight with her mother, Demeter.
When Persephone is with Hades the earth is wracked by the sorrow of her mother. But, when Persephone returns from the underworld to walk the earth again, Demeter pours forth the blessings of Spring to welcome her beloved daughter home.
