Demeter had a daughter named Persephone. Demeter loved her daughter and they went everywhere together. But, Hades wanted Persephone to himself...
Hades decided to take Persephone by surprise. He split open the ground and took her. A couple of pigs fell down too...
Demeter was in despair when Persephone was lost, and didn't let anything grow. Persephone also was unhappy with her life in the Underworld. The only food that was available was a pomegranate tree. But, Persephone didn't want the Food of the Dead.
Demeter found out about where Persephone was from a person who was the brother of a swine herd. He saw the pigs fall. So, Demeter told Zeus to send Hermes to the Underworld to get Persephone back. Lost in thought, Persephone ate from the pomegranate tree...Food of the Dead
let her go!!
Reunited with Persephone, Demeter was happy again, and decided to let plants grow. But, because she ate the pomegranate, Persephone had to spend half of each year in the Underworld and the other half with Demeter.
When Persephone is in the Underworld, Demeter makes it autumn and winter. When it is spring and summer, Persephone is with Demeter.
