Gérard de Sède by the Tomb of Louis Bertram Lawrence, who died on 25 July 1954.

The claim that Louis Lawrence's Tomb at Les Pontils was the “prototype” for Nicolas Poussin's painting “Les Bergers d'Arcadie”, was first introduced into the corpus of Rennes-le-Château mythology by Jean Pellet and Gérard de Sède in their article “Le Secret de Nicolas Poussin” (Le Grand Albert, Journal des Sciences Secrets, Number 9, pages 46-48, 1972).

The Louis Lawrence Tomb was destroyed by the owner of Les Pontils in 1988, after he'd had enough of treasure hunters trespassing on his property..

The Tomb of Louis Lawrence remains at the forefront of Rennes-le-Château mythology and has inspired [fantasy] links with Shugborough Hall and Oak Island, Nova Scotia among its psychedelic kaleidoscope of phantasmagorial colours.
