a religious festival held in Attica, in ancient Greece, in honor of the goddess Demeter and her daughter the goddess Persephone (Kore).
The cult of Demeter and Persephone was one of the most ancient agricultural cults. The Eleusinian mysteries, celebrated from earliest times in Eleusis, became an Athenian state festival after Eleusis was incorporated into the league of Attic states in the late seventh century B.C. Regardless of sex and social position, all of the citizens of Athens, including slaves, had the right to be initiated into the mysteries, which were celebrated in late September or early October. The ritual included a solemn procession along the Sacred Way from Athens to Eleusis and the mysteries proper, which consisted of representations of Demeter’s sorrow at the loss of her daughter, her search for Persephone, and her joy upon Persephone’s return. The details of the Eleusinian mysteries, which apparently included pantomime and the recitation of sacred texts, are unknown.
