Once upon a time there was a girl named Persephone. She was the daughter of the goddesses and God Demeter and Zeus. Hades, the god of the underworld would often visit the surface. He fell in love with Persephone and wanted to marry her
Demeter is furious when she finds out her daughter is missing and roams the Earth looking for her neglecting her job of harvesting the Earth. The Earth then gets dry and unfertilized
Hades then comes up to Earth with his black horses and takes Persephone to the underworld against her will
During her time in the underworld, Hades shows Persephone his real self that he has not shown anyone and she starts to fall in love with him
Persephone decides to go back home to her Mother. Hades feeds her a pomegranate because it is told that when you feed your victim then they are guaranteed to come back to you
Persephone goes back to her mother and often visits Hades in the underworld. The people in Greece believe that the seasons change because of the months where Demeter was looking for her daughter. Winter and Autumn were the months she neglected her job of harvesting the Earth.
