The Eleusinian Mysteries were the most famous of the secret religious rites of ancient Greece, held for Demeter and her daughter Persephone at Eleusis, near Athens, for more than a thousand years. Initiates, sworn to secrecy, experienced rites based on the myth of Persephone's abduction and return, and believed they would gain a happier lot after death.

The myth
The Mysteries were based on a story told most fully in the Homeric Hymn to Demeter, probably composed in the seventh or sixth century BCE. Hades, lord of the underworld, seized Persephone (also called Kore, "the maiden") while she gathered flowers. Her grieving mother, the grain goddess Demeter, searched the earth and, disguised as an old woman, came to Eleusis, where she served in the household of King Celeus. When Demeter revealed her divinity she commanded that a temple be built for her. In her grief she withheld the growth of crops until Zeus arranged Persephone's return; because Persephone had eaten pomegranate seeds in the underworld, she had to spend part of each year there. Before departing, Demeter taught her rites to the rulers of Eleusis.
The story of loss and reunion was linked to the agricultural cycle and to hopes about death. The hymn declares blessed those who have seen the rites, while the uninitiated have no such share after death.
Origins and organization
The cult probably had roots in the Bronze Age, and archaeological remains at Eleusis go back to the Mycenaean period, though the continuity of the rites is debated. From the sixth century BCE the Mysteries came under Athenian control and grew into a panhellenic institution. Two Eleusinian families held the main priesthoods: the Hierophant, who revealed the sacred objects, came from the Eumolpidae, and the torchbearer (dadouchos) from the Kerykes.
Participation was unusually open. Men and women, free and enslaved, could be initiated as long as they spoke Greek and were not polluted by bloodshed; in Roman times emperors such as Hadrian and Marcus Aurelius were among the initiates. Revealing the secrets was a grave crime: in 415 BCE the Athenian statesman Alcibiades was accused of profaning the Mysteries, a scandal that contributed to his downfall.
Stages of initiation
Initiation took place in stages. The Lesser Mysteries, held in spring at Agrai beside the Ilissos river near Athens, served as a preliminary purification. The Greater Mysteries took place each autumn in the month of Boedromion (September-October) and lasted about nine or ten days. Sacred objects were brought from Eleusis to Athens; the initiates (mystai) assembled, were purified by bathing in the sea, sacrificed piglets and fasted. A great procession then walked the Sacred Way back to Eleusis, invoking the god Iacchus.
At Eleusis the climactic rites took place at night in the Telesterion, a large hall of initiation. Ancient writers speak of things "done," "said" and "shown": ritual actions, words and the display of sacred objects by the Hierophant amid blazing light. Those who returned a second year could attain the higher grade of epoptes, "one who has seen." Initiates broke their fast by drinking the kykeon, a drink of barley and water flavored with pennyroyal.
The secret and modern theories
The secret was kept remarkably well, and what exactly happened in the Telesterion remains unknown. Much of what is claimed comes from later Christian critics, such as Clement of Alexandria, whose testimony must be read with caution. Ancient admirers, including Cicero, wrote that the Mysteries taught people to live with joy and to die with better hope.
In 1978 R. Gordon Wasson, Albert Hofmann and Carl A. P. Ruck argued in The Road to Eleusis that the kykeon contained a psychoactive preparation derived from ergot, a fungus that grows on grain. The hypothesis has attracted popular interest but remains unproven and disputed; critics note the lack of direct evidence and argue that the power of the rites could come from fasting, darkness, drama, music and collective emotion. For comparison with other initiatory cults, see Orphism and the cult of Attis.
Decline and legacy
The Mysteries continued under Roman rule until the Christian emperor Theodosius I issued decrees against pagan cults in the 390s CE; the sanctuary was closed, and in 396 the Visigoths under Alaric I devastated what remained. The ruins at modern Elefsina can still be visited. The Eleusinian Mysteries fascinated later writers and esotericists, who saw in them a model of initiation into hidden wisdom and of mystical experience. Scholars also discuss them in connection with the motif of the dying and returning deity, though Persephone's story differs from that model in important ways. See also Greek mythology.

Frequently asked questions
What happened in the Eleusinian Mysteries?
Initiates underwent purification, fasting and a procession from Athens to Eleusis, then took part in secret nighttime rites in the Telesterion, where sacred objects were revealed by the Hierophant. The exact content was never disclosed. The rites were based on the myth of Demeter and Persephone and promised a better fate after death.
What was the kykeon?
The kykeon was a drink of barley and water flavored with pennyroyal, taken by initiates to break their fast, echoing Demeter's drink in the Homeric Hymn. In 1978 Wasson, Hofmann and Ruck proposed that it contained psychoactive ergot. This theory is popular but remains unproven and is disputed by many scholars.
When did the Eleusinian Mysteries end?
The Mysteries ended in the late fourth century CE, when the Christian emperor Theodosius I issued decrees against pagan worship and the sanctuary was closed, around 392. In 396 the Visigoths led by Alaric I sacked Eleusis. The rites had been celebrated for more than a thousand years.
