 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).The term "Rose Line" as the Paris Meridian was given by Dan Brown in his 2003 novel "The Da Vinci Code" as an alternate name for "the world's first prime meridian", identified as the Paris Meridian.
