Laurent Buchholtzer, alias “Octonovo”, wrote the following about Louis Vazart: “The author would himself proceed to destroy some of the final copies of his book [Abrégé de l'Histoire des Francs: Les Gouvernants et Rois de la France, 1978] when he became convinced that it was all an exercise in mystification” (Rennes-le-Château, Une Affaire Paradoxale, Footnote 74, page 61, 2008).

Elsewhere – in the journal Actes du Colloque 2006 (his article entitled Pierre Plantard, Geneviève Zaepfell and the Alpha-Galates, pages 127-144) – Octonovo wrote about how “everyone here understands that, behind the myth of the Priory of Sion, there was a fantasy, and that behind the Priory of Sion itself there was a weaver of fantasies”, concluding, “Today I propose going one step further: behind that weaver of fantasies, right to the very source of the matter” stating that “Plantard’s recipes for success are also well known: forged documents, deception and the manipulation of writers of greater or lesser degrees of talent until the day arrived when, thanks essentially to L'Enigme Sacrée [The Holy Blood and the Holy Grail], their services were no longer needed.” Octonovo concluded “If one explains to the millions of readers of Dan Brown's books that the origin of The Da Vinci Code lies in a hallucinating clairvoyant who was also totally devoted to Adolf Hitler, the connection will probably strike them as ridiculous. Even so this sort of phenomenon can teach us a lot about mythology and esotericism.”

Plantard's decision to include Roger-Patrice Pelat in the Priory of Sion mythology turned out to be fatal: “After that Plantard was threatened with legal action by the Pelat family and the time had therefore come for him to do a disappearing act to his house in the south of France. He was then 74 years old and his life was effectively over – nothing more was heard of him. We should bear in mind that quite a few people have retained fond memories of Plantard. All the people I spoke to thought he was either a nice person apart from his being a mythomaniac, or alternatively someone to be pitied because his mythomania so far exceeded what he amounted to in reality.”

A more substantial account of what Octonovo wrote about the Priory of Sion is contained in chapter three of his book Rennes-le-Château, Une Affaire Paradoxale (Editions de l'Oeil du Sphinx, 2008).

Bearing all of this in mind it can be easily determined why Michael Baigent and Richard Leigh turned to writing about other things and why Henry Lincoln turned to writing about Sacred Landscape Geometry.
