 Brown based this on material found in the Priory of Sion documents of the 1960s, where neither the Zero Meridian nor the sunlight line in St Sulpice are called Rose Line.Philippe de Cherisey in his 1967 novel "Circuit" claimed his girlfriend "Roseline" ("Roseline Cartades", described as "A Machiavellian Virgin") was killed in a car crash and was buried in a beautiful tomb by the Zero Meridian.The Zero Meridian was not called "Roseline" in "Circuit", nor was it called that in the 1967 Priory of Sion document "Le Serpent Rouge", that deals with the Zero Meridian being conflated with the sunlight line in St Sulpice.
