The Large Parchment is The Priory of Sion

The True Believers in the “mystery” of Rennes-le-Château continue to claim that the two “parchments” are genuine and detach Pierre Plantard and Philippe de Chérisey from having any responsibility for their creation.

Assuming that Henry Lincoln's decoding analysis of the Large Parchment is correct – taken below from the 1974 BBC 2 documentary “The Priest, The Painter and The Devil” – it is very easy to prove that it is the work of Pierre Plantard and Philippe de Chérisey because it requires the words “P. S. Prae-Cum” from a “tombstone” that did not exist before the mid 1960s – and is first found in ‘Madeleine Blancassall’, Les Descendants Mérovingiens ou l’énigme du Razès wisigoth (1965). The same source as the decrypted “Bergère pas de tentation...” message.

Interestingly, Gérard de Sède wrote “Aperçus sur la Cryptographie Médiévale” (Insights Into Medieval Cryptography) (Bulletin de L'Amicale des Réservistes du Chiffre, Nouvelle série, 10e Année, Décembre 1963), where some of its symbols were previously utilised by Pierre Plantard in his 1961 document “Gisors et son secret…”. The True Believers have got more than enough material to debunk the whole subject matter but all arrive at their final denouement because of simple-minded tunnel vision (Tony Bontempi, Philippe Duquesnois, Frédéric Fons, François Lange, Patrick Mensior, Paul Saussez, Yannick Thomasin, Gérard Villemin). Besides, we know that what REALLY inspired the creation of the “parchments” was the popularity of The Dead Sea Scrolls in France during the 1960s – the proof of which exists in the correspondence between Pierre Plantard and Philippe de Chérisey – but our “researchers” do not want to know that.

The decoding technique demonstrates that only the creator of the Large Parchment could have known the decryption – because in reality there is no “decryption” – it is only a “fake decoding” – as the video clip below makes clear. The current generation of True Believers in the “mystery” of Rennes-le-Château are so boring and so out of touch.
