Demeter asked Zeus, a brother of Hades, to return Persephone. When Zeus declined.
One day, Persephone went on a walk.
Her uncle, Hades then kidnapped her.
Persephone, heartbroken, went to look for her daughter . 9 days and nights.
Demeter then stopped looking for Persephone, she was nowhere found. Out of sadness and anger, she stopped everything from growing.
He agreed to allow Persephone’s return if she hadn't eaten with Hades. Persephone had eaten 6 pomegranate seeds in the underworld already, Zeus said that she would spend 6 months with her mother and 6 months with Hades.
That is the cause of our seasons. and how we have seasons.
