The book was later revealed to be based on a hoax originating with Pierre Plantard in the mid-20th century.

* Pierre Plantard, the mastermind behind the Priory of Sion hoax who claimed to be Merovingian, a pretender to the throne of France.

Pierre Plantard, the creator of the Priory of Sion mythology, tried to argue that the sepulchre at Les Pontils was a " prototype " for Poussin's painting, but it was situated directly opposite a farmhouse ( behind the foliage ) and was not in the " middle of nowhere " in the French countryside, as is commonly assumed.

The precursor to these Rosslyn theories is the 1982 book The Holy Blood and the Holy Grail by Michael Baigent, Richard Leigh and Henry Lincoln that introduced the theory of the Jesus bloodline in relation to the Priory of Sion hoax-the main protagonist of which was Pierre Plantard, who for a time adopted the name Pierre Plantard de Saint-Clair.

Pierre Plantard was born in 1920, in Paris, the son of a butler and a concierge ( described as a cook for wealthy families in police reports of the 1940s ).

According to a police report on the Alpha Galates dated 13 February 1945 the organisation was only composed of at most 50 members, who resigned one after the other as soon as they sized up the president of the association ( Pierre Plantard ) and figured out that it was not a serious enterprise.

According to the late Robert Amadou ( 1924 – 2006 ), Pierre Plantard in 1953 was accused of selling degrees of esoteric orders for exorbitant sums.

French researchers dispute the connection between Robert Amadou and Pierre Plantard.

On 25 June 1956, Pierre Plantard and André Bonhomme legally registered in the town of St Julien-en-Genevois a new association called the Priory of Sion, based in Annemasse close to the French border near Geneva.

Plantard added that his past relative, Abbé Pierre Plantard, former vicar of the Basilica of St. Clotilde, Paris, drew up genealogies giving the survival of the line of Dagobert II on 18 March 1939.

But it was due to the success of de Sède's book L ' Or de Rennes that Pierre Plantard became famous, as the guardian of the secret of Rennes-le-Château.

In 1989, when Plantard revised his claims about the Priory of Sion, it was stated in a 1989 issue of Vaincre: " The parchments of Blanche of Castile were in Etienne Plantard's safe-deposit box in London since November 1955 and they did not ' mention ' Dagobert, or a Dagobert II and Pierre Plantard de Saint-Clair was never ' a Merovingian pretender ' to the throne of France: His lineage results from the Counts de Rhédae and by the female line of Saint Clair-sur-Epte, which has no relationship with ' Sinclair '.

From 1975 Pierre Plantard used the surname Plantard de Saint-Clair, described as an epithet by Jean-Luc Chaumeil, following his interview with Plantard in the magazine l ’ Ère d ’ Aquarius.

Pierre Plantard was hypothesised as the direct descendant of Jesus Christ.

This initiative by Plantard had an unexpected consequence ; in October 1993, the judge investigating the Pelat scandal had Pierre Plantard's house searched.
