Book excerpt: The existence of the Holy Grail has long been debated, and many of these debates focus on the intellectualized or psychological aspects of it. This work explores the events that gave rise to the legend of the Holy Grail and pays special attention to the texts that form the body of the legend, as well as historical facts about the life of Christ, the Crusades, and the fall from grace of the Knights Templar. The book examines the legitimacy of the claims made by several present-day believers and also introduces a new theory of multiple grails (and the evidence supporting this theory), which, the author believes, answers many of the otherwise unanswered questions surrounding the Holy Grail.
