In 1969, while on holiday in the
Cévennes, Lincoln happened to read
Le Trésor Maudit de Rennes-le-Château (trans:
The Accursed Treasure of Rennes-le-Château), a book by
Gérard de Sède about an alleged hidden treasure. The book reproduced copies of Latin parchments that had been found by the parish priest of
Rennes-le-Château,
Bérenger Saunière, within a pillar inside his Romanesque church. Inspired by what appeared to be secret codes hidden in the Latin text, Lincoln did some research about the parchments and a possible treasure, writing several books presenting his theories about the area. He presented three documentaries in the
Chronicle series for BBC2: "The Lost Treasure of Jerusalem", shown in February 1972, "The Priest, the Painter and the Devil", shown in October 1974, and finally "The Shadow of the Templars", shown in November 1979. One of the parchments (which was later shown to be a forgery, since the writing was written in modern French and not in 18th or 19th century French) involved a series of raised letters throughout its Latin text, spelling out a message:
À Dagobert II Roi et à Sion est ce trésor et il est là mort (
trans: "This treasure belongs to King
Dagobert II and to Sion, and he is there dead"; or, "This treasure belongs to King Dagobert II and to Sion, and it is death"). This referred to the
Merovingian king Dagobert II, who had been assassinated without a direct heir in the 7th century, thereby ending his branch of the dynasty. Later research, however, showed that de Sède's book had actually been written at the instigation of
Pierre Plantard as part of an elaborate hoax to promote a society known as the
Priory of Sion, and Plantard claimed to be descended from Dagobert II. Pierre Plantard died in 2000. ==
