Who stole persephone?
Hades, the god of the underworld did. When she was gone, her mother Demeter who was the goddess of growth mourned and went lookong for Persephone, and nothong could grow. And animals and people starved and complained to the gods. So Zeus persuaded Hades to let Persephone go back to her mother for half the year. That is why plants grow best during one half of the year, but in the winter they do not.
