In classical antiquity, the earliest and most celebrated mysteries were the Eleusinian. At Eleusis, the worship of the agricultural deities Demeter and her daughter Persephone, also known as Kore, was based on the growth cycles of nature. Athenians believed they were the first to receive the gift of grain cultivation from Demeter (41.162.98). Extraordinarily, the goddess herself revealed to them the solemn rites in her honor, as we learn in the Homeric hymn to Demeter, which relates the foundation myth of the Eleusinian cult (14.130.9). Hades abducted Persephone while she was picking flowers with her companions in a meadow and carried her off to the Underworld (07.128.1). After wandering in vain looking for her daughter, Demeter arrived at Eleusis. There the wrath of the distressed mother caused a complete failure of the crops, prompting Zeus to order his brother Hades to return the girl. He cunningly tricked Persephone into eating some pomegranate seeds before leaving, thus condemning her to spend part of the year in the Underworld as his wife and the rest among the living with Demeter (24.97.110).
During the Great Eleusinia, the public aspect of which culminated in the grand procession from the center of Athens to Eleusis along the Sacred Way, the actions and experiences of the initiates mirrored those of the two goddesses in the sacred drama (drama mystikon). In the early sixth century B.C., the “Queen of the Underworld” persona of Kore was introduced and a nocturnal initiation rite called katabasis was added to the festival: a simulated descent to Hades and ritual search for Persephone. Before the entrance to the Telesterion, the central hall of the sanctuary where the secret rites were performed, priestly personnel holding torches met up with the initiates, who until then were wandering in the dark (28.57.23). At the Eleusinian mysteries, the tension between public and private, conspicuous and secret was inherent in the double nature of the cult. Unlike city-state (polis) religion, participation was restricted to individuals who chose to be initiated, to become mystai. At the same time, it was far more inclusive, being open not only to Athenian male citizens, but to non-Athenians, women, and slaves.
