Priory of Sion mythology
Priory of Sion document Au Pays de la Reine Blanche
 states that "Rennes-les-Bains is located precisely on the Zero Meridian, which connects Saint-Sulpice in Paris" adding that "the parish of Rennes-les-Bains guards the heart of Roseline", in this context being a reference to
Saint Roseline de Villeneuve. Au Pays de la Reine Blanche also referred to "the line of the Zero Meridian, that is to say the red line, in English: 'Rose-line'".
 Later in 1978, Pierre Plantard also referred to the "red line of the meridian, the 'Rose-Line'...since Roseline, the Abbess of the 'Celle aux Arcs', celebrates her feast day on 17 January... and her legend is well worth a read".
The document entitled Le Serpent Rouge - Notes sur Saint-Germain-des-Près et Saint-Sulpice de Paris
 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."
 Another document by Philippe de Chérisey entitled Circuit,
 in Chapter VII, adds the detail that Roseline was killed in a car accident whilst working as a double on the Television film La beauté sur la terre (1968),
 a film that also starred Philippe de Chérisey under his stage name of Amédée.
 The story about Roseline in Circuit also involves an imaginary character named Charlot who appears frequently throughout Circuit and both characters are patently imaginary beings appearing in one of Philippe de Chérisey's
Chapter XIII of Circuit is devoted to the Zero Meridian, with de Chérisey claiming it was established by
Till Eulenspiegel (before
Jean Picard), listing key sites that it passes through (in a fictional work attributed to Abbé François-Pierre Cauneille). In this chapter Roseline is called 'Fisher Woman', preferring herself to be known as "Di O Nysos, DON" ("dondon" is French slang for "fat woman"), an
otherworldly being who organises funerals for the dead who are still living in her new
Citroen 2CV (the make of car she was killed in).
