Another large part of the mystery of Rennes-le-Chateau moved from reality to legend on the weekend with the passing of French author Gérard de Sède. De Sède was known mainly for his role in popularizing the legend of Rennes-le-Chateau through his book Le Tresor Maudit (since translated into English as The Accursed Treasure of Rennes-le-Chateau, see Amazon UK), which Henry Lincoln first stumbled across to start the HOLY BLOOD, HOLY GRAIL juggernaut. Through his association with Pierre Plantard and Phillipe de Cherisey, de Sède occupied a central place in the mystery. However, he was also the author of many other French ‘mystery’ books and, though a controversial figure, was warmly regarded by many researchers. Gérard de Sède was 82. Thanks Filip.
