Starting from the huge mythology developed from the Sixties to our days – made of hypotheses, apocryphal writings, false documents and bizarre characters [mainly from Pierre Plantard] – Christian Doumergue raises the key question: how was this all born? With the aim to trace its origins, the author gives birth to a rich compendium identifying – in a systematic way – the myriad of sources and inspirations that gave rise to what we now know as the “myth of Rennes-le-Château”. Never before has this goal been targeted (and reached) with so much determination and discipline.
