The Shroud of Turin - the burial cover of Jesus Christ, on which, as millions of believers believe, the image of the Savior was miraculously imprinted - is the most famous relic of the Christian world, surrounded not only by a mass of legends and speculation, but also by many very real dark secrets associated with heretical secret societies and sinister conspiracies among the Catholic clergy. After radiocarbon dating in 1988 determined that the time of manufacture of the shroud did not date back to the beginning of our era, but to the Middle Ages or Renaissance, the controversy over its authenticity not only did not subside, but flared up with renewed vigor. If this relic is a fake, then how did a forger operating 500 years ago manage to create an image that hundreds of researchers armed with the most modern technology and materials could not duplicate? Finally, who was the madman who, during the rampant Inquisition, dared to forge a sacred relic - the shroud of Christ himself?.. In search of answers, Lynn Picknett and Clive Prince, authors of the bestseller Leonardo da Vinci and the Brotherhood of Zion. Revelations of the Templars,” they came to the conclusion that the great Leonardo da Vinci, a brilliant artist, scientist, inventor and, probably, the master of a mysterious secret society, was directly related to the very strange and controversial history of the Shroud of Turin. This book reveals many dark secrets hidden behind the possible falsification of the shroud by the master Leonardo, and sheds light on the activities of the so-called “shroud mafia,” most likely associated with the powerful Priory (Brotherhood) of Sion.
