ABSTRACT
In the exploration of my theme I have often found myself accompanied by Roger Caillois12. He was a man curious about everything, who applied his imagination and poetic vision to the mineral world, seeking parallels between social facts and the mineral kingdom. Stones played a large part in this curiosity, for he wrote no less than three books devoted to them “La Pierre-écriture”, “Pierres et autres textes” and “Pierres poésie”, all now sadly out of print. In his numerous studies he was generally interested in the connections he discerned between the various elements of the universe and human activities in the deeper sense (Le mythe et l’homme (1938), L’Homme et le sacré (1939), Au coeur du fantastique).
