Roger Caillois’ extraordinary collection of stones is illustrated along with texts that trace his profile as an eclectic and atypical intellectual.

Even though they belong to the mineral kingdom, the stones in the collection of the French writer Roger Caillois appear miraculously similar to works of art. Beginning from this mysterious but captivating link between two such apparently distant universes, the book collects a carefully curated selection of the finest stones in the collection and recounts the life of Caillois (sociologist, member of the surrealist movement…), reviewing and presenting his essays on stones. The persona and the personality of this atypical 20th-century intellectual emerge from the essay by Stefano Salis, who introduces us to Caillois’ world and that of Marguerite Yourcenar, who took his place in the Académie de France after his death with a speech reviewing his life and work. The literary critic Carlo Ossola traces the outlines of the cultural climate in which Caillois lived and operated, while François Farges, now in charge of the collection, illustrates it in the final essay.
