However, it was a rule of the Fates that whoever consumed food or drink in the Underworld was doomed to spend eternity there. Before Persephone was released to Hermes, who had been sent to retrieve her, Hades tricked her into eating pomegranate seeds, (six, seven, eight, or perhaps four according to the telling)which forced her to return to the underworld for the winter each year. In some versions, Ascalaphus informed the other deities that Persephone had eaten the pomegranate seeds. When Demeter and her daughter were united, the Earth flourished with vegetation and color, but for some months each year, when Persephone returned to the underworld, the earth once again became a barren realm.
