Before the Birth of Jesus, the Ancient Greeks found salvation in sacred beer and wine routinely consumed as part of the so-called Ancient Mysteries-elaborate rites that led initiates to the brink of death. In the 1970s, renegade scholars claimed these beverages-the original sacraments of Western civilization-were spiked with mind-altering drugs. In recent years, vindication for the disgraced theory has been quietly mounting in the laboratory. The constantly advancing fields of archaeobotany and archacochemistry have hinted at the enduring use of hallucinogens by our ancestors. If these sacraments survived for thousands of years in our remote prehistory, from the Stone Age to the Ancient Greeks, did they also survive into the age of Jesus? Was the Eucharist of the earliest Greek-speaking Christians, in fact, a psychedelic Eucharist? With an unquenchable thirst for answers. Brian C. Muraresku takes the reader on his twelve-year global hunt for proof. A magical mystery tour of the museums, archives catacombs, and archaeological sites of the Old World reveals the first scientific data for the ritual use of psychedelic drugs in classical antiquity.
