The Psychedelic Origin of Christianity, Jesus Mushroom.
The Sacred Mushroom and the Cross (1970) is a book by the British archaeologist John Marco Allegro. His early career focused on studying the earliest manuscripts of the Bible, the Dead Sea Scrolls. With this book, however, many say that it ruined his career, although others say it gave him the fame that he deserved.
