He also wrote the scripts for a French comic strip, Atomas, about an atomic-powered superhero, appearing in the weekly magazine Mon Journal in the late 1940s.
For the same magazine Charroux wrote a science fiction adventure in serial form, "Prof. Barthelemy's Flying Island."
According to Charroux, Hyperborea was situated between Iceland and Greenland and was the home of a Nordic White race with blonde hair and blue eyes.
[7][8] Robert Charroux developed an active interest in the alleged treasure of Rennes-le-Château, following up claims made by Noel Corbu in the local press in 1956 that it was discovered by Bérenger Saunière during the late 19th century.
Charroux also distributed a leaflet about this entitled L’ébouriffante histoire du "curé aux milliards" that has not survived, but is referred to in French newspapers of the period.
[10][11] He described his activities there in his 1962 book Trésors du Monde enterrées, emmurés, engloutis (Fayard) that was published in English in 1967.
