The secretive Mysteries conducted at Eleusis in Greece for nearly two millennia have long puzzled scholars with strange accounts of initiates experiencing otherworldly journeys. In this groundbreaking work, three experts - a mycologist, a chemist, and a historian - argue persuasively that the sacred potion given to participants in the course of the ritual contained a psychoactive entheogen. The authors then expand the discussion to show that natural psychedelic agents have been used in spiritual rituals across history and cultures.

Violence and the Sacred is Rene Girard's landmark study of human evil. Here Girard explores violence as it is represented and occurs throughout history, literature, and myth. Girard's forceful and thought-provoking analyses of Biblical narrative, Greek tragedy, and the lynchings and pogroms propagated by contemporary states illustrate his central argument that violence belongs to everyone and is at the heart of the sacred.

The mysticism and fairy folklore of Celtic England, Scotland, the Isle of Man, Brittany, and Wales is explored in this production, which focuses on interviews conducted with everyday citizens about their beliefs, sightings, and encounters in the early 20th century, followed by an anthropological examination of evidence. It is an exploration of the spirit world, of the Sidhe, the "good people", who are claimed to interact mischievously with the populace - sometimes even abducting them and leaving only the victims' clothes behind, transporting them far distances, and killing livestock.

A groundbreaking dive into the role psychedelics have played in the origins of Western civilization, and the real-life quest for the Holy Grail that could shake the Church to its foundations.
