The document entitled Le Serpent Rouge - Notes sur Saint-Germain-des-Près et Saint-Sulpice de Paris[REF] conflates the Paris Meridian with a gnomon in the Parisian church of Saint-Sulpice marked in the floor with a brass line, which it calls the "Red Serpent".
Philippe de Chérisey in his document Stone and Paper recounted a story that a Roseline was also the name of his acquaintance: "there was a Roseline I knew who died on 6 August 1967, on the Feast of the Transfiguration, when leaving the zero meridian by car."[REF]
