Since it is winter in the Southern Hemisphere, I thought I would look at the Greek origin story to explain the seasons.
Hades, in Greek Mythology, was Lord of the Underworld. He saw Persephone, the daughter of Demeter and fell in love with her. Demeter was the goddess of the harvest and was so upset when Hades abducted Persephone, that she wandered the earth and refused to allow the earth harvests to ripen.
So Persephone became Queen of the Underworld. Origin of the above quote at Yahoo answers.
