* Quoting Pierre Plantard about The Holy Blood and the Holy Grail: “There is part of the book that owes more to fiction than fact. Especially the part that deals with the lineage of Jesus. How can you prove a lineage of four centuries from Jesus to the Merovingians? I have never put myself forward as a descendant of Jesus Christ.”

Pierre Plantard: “J'admets ou l’énigme sacrée est un bon livre, mais il faut avouer qu’il y a une partie de roman, particulièrement en ce qui concerne la lignée de Jésus. Comment pourrait-on prouver une lignée de quatre siècles qui vont de Jésus aux Mérovingiens. Je ne me suis jamais présenté comme un descendant de Jésus voyons.”
