Roger Caillois (1913–1978) was a brilliant polymath and virtuoso essayist. The subject of his attention in this book is the mysterious - be it the mysterious creations of the creative imagination of artists or the strange, exciting creations of nature. The unknown does not mean the unknowable, Roger Caillois is convinced. From his point of view, surprise at a mystery only stimulates the inquisitive mind of the researcher, arouses the desire to “decipher” the meaning of unsolved phenomena, to find the key to an unknown code. The reader will enthusiastically follow the development of analytical thought, inspired by the discoveries of the writer’s creative intuition. The works included in the book are published in Russian for the first time. The publication was carried out within the framework of the Pushkin program with the support of the French Ministry of Foreign Affairs and the French Embassy in Russia. Ouvrage réalisé dans le cadre du program daide à la publication Pouchkine avec le soutien du Ministère des Affaires Etrangères Français et de l Ambassade de France en Russie.Roger Caillois: AU CŒUR DU FANTASTIQUE.
