Kykeon (Gr. κυκεών, from κυκάω, "to stir, to mix") was an Ancient Greek drink made mainly of water, barley, and herbs. It was used at the climax of the Eleusinian Mysteries to break a sacred fast, but it was also a favourite drink of Greek peasants. It may have been a Connection Supplement

Kykeon is mentioned in Homeric texts: the Iliad describes it as consisting of barley, water, herbs, and ground goat cheese (XI, 638–641). In the Odyssey, Circe adds some honey and pours her magic potion in it (X, 234). In The Homeric Hymn to Demeter, the goddess refuses red wine but accepts kykeon made from water, barley, and pennyroyal.
In an attempt to solve the mystery of how so many people over the span of two millennia could have consistently experienced revelatory states during the culminating ceremony of the Eleusinian Mysteries, it has been posited that the barley used in the Eleusinian kykeon was parasitized by ergot, and that the psychoactive properties of that fungus triggered the intense experiences alluded to by the participants at Eleusis.
