Yes, people: Christ, the root of Jesse, was nothing more than a code for an hallucinogenic mushroom (to control the masses, you see)!
From Wickedpedia (John Allegro):
The Sacred Mushroom and Christian Myth
The Sacred Mushroom and the Cross argued that Jesus in the Gospels was in fact a code for a type of hallucinogen, the Amanita muscaria, and that Christianity was the product of an ancient "sex-and-mushroom" cult. Critical reaction was swift and harsh: fourteen British scholars (including Allegro's mentor at Oxford, Godfrey Driver) denounced it and the publisher even apologized for publishing it. Sidnie White Crawford wrote of the publication of Sacred Mushroom, "Rightly or wrongly, Allegro would never be taken seriously as a scholar again."
In 1979 Allegro published The Dead Sea Scrolls and the Christian Myth in which he argued that because the authors of the Christian gospels did not understand Essene thought, they had confused the meaning of the scrolls and built the Christian tradition based on the misunderstanding of the scrolls. Allegro argued that story of Jesus was based on the crucifixion of the Teacher of Righteousness in the scrolls.
