The Homeric Hymn to Demeter, composed in the late seventeenth or early sixth century B.C.E., is a key to understanding the psychological and religious world of ancient Greek women. The poem tells how Hades, lord of the underworld, abducted the goddess Persephone and how her grieving mother, Demeter, the goddess of grain, forced the gods to allow Persephone to return to her for part of each year.
