The Hidden Church of the Holy Graal (Barnes & Noble Digital Library): Its Legends and Symbolism

The author was among the first to study western occultism as a spiritual tradition rather than as pseudoscience or religion. This 1909 survey of the Holy Grail legend weaves together the history of how a pagan folk-tale became a vital Christian allegory. Waite makes it a point to extensively describe all source texts of the Grail legend—employing readable yet interesting prose.
