Persephone was the daughter of Zeus and Demeter. She was abducted by Hades, god of the underworld, who took her to be his wife. Her mother Demeter caused plants to stop growing in grief. Eventually a deal was made where Persephone would spend six months with Hades and six months above ground with her mother. This explained the changing seasons. As queen of the underworld, Persephone's symbols included bats, flowers, and pomegranates.
