In ancient Greek mythology and religion, Persephone, also called Kore or Cora, is the daughter of Zeus and Demeter. She became the queen of the underworld after her abduction by her uncle Hades, the king of the underworld, who later took her into marriage. The myth of her abduction, her sojourn in the underworld, and her cyclical return to the surface represents her functions as the embodiment of spring and the personification of vegetation, especially grain crops, which disappear into the earth when sown, remain hidden for a period, sprout from the earth, and are harvested when fully grown.
