The Templar Revelation: Secret Guardians of the True Identity of Christ is a book written by Lynn Picknett and Clive Prince and published in 1997 by Transworld Publishers Ltd in Great Britain, Australia and New Zealand. It proposes a fringe hypothesis regarding the relationship between Jesus, John the Baptist and Mary Magdalene, and states that their true story has been suppressed by the Roman Catholic Church through, among other tactics, the conscious selection of the texts that make up the canonical New Testament, their campaigns against heresy, and their propaganda against non-Christians. Summary While researching the life and works of Leonardo da Vinci, including "his part in faking the Turin Shroud" which the authors wrote about in their book Turin Shroud— In Whose Image?, they discovered a number of signs of unorthodox Christian thinking in the imagery used to portray some of the central characters in the New Testament, especially John the Baptist. Some paintings examined for their unusual choice of imagery include the two versions of Madonna of the Rocks and The Last Supper. In the latter painting, they propose that the person in the painting seated, from a viewer's point of view, to the left of Jesus is Mary Magdalene rather than John the Apostle, as most art historians identify that person. Furthermore, they point out that their body angles form the letter M, a reference to the Magdalene, and that she and Jesus are dressed in similar but oppositely colored clothes, a negative image of each other. They also mention a number of other signs: a mystery knife pointed at one of the characters, that Leonardo da Vinci himself is in the painting with his face pointing away from Jesus, and that Jesus is confronted by an admonishing hand to his right making “the John gesture,” an index finger pointing up. In trying to understand the significance of these unusual images they conducted research into what they term a “thread of heresy” that reaches back over 2000 years. They claim to find evidence for this occult tradition in such assorted subjects as The Knights Templar, the Cathars, Gnosticism, the Holy Grail, and the legends connected with southern France, and in particular the town of Rennes-le-Château. They utilise the historical and biblical scholarship of such people as Morton Smith, Hugh J. Schonfield, G.R.S. Mead, Frances A. Yates, and Geza Vermes on which to build their claims. Among their
