On this week's episode of Mythic Existence, host Jack Daly discusses the findings of Brian Muraresku's new book, "The Immortality Key: The Secret History of the Religion With No Name." The "religion with no name," Muraresku posits, was born out of the Mysteries of Eleusis, an initiation ritual from Ancient Greece. Plato, Pythagoras, and Marcus Aurelius were initiates of this ancient Mystery religion, which centered around the myths of Persephone, Demeter, and Dionysus. Using scientific evidence, paired with ancient literature, texts from the Vatican Secret Archives, and frescos from the Vatican's underground, Muraresku argues that the religion with no name was based off of the ingestion of a psychedelic potion that was brewed by the witches of Eleusis. Furthermore, he says that this elixir may have inspired the Catholic Eucharist, and that Jesus styled himself after Dionysus to convert the inhabitants of the ancient Levant.
