Anyone who might be surprised to find an issue on the figures of myth and gender appearing under the aegis of the poet of Pierres or Récurrences dérobées can only be referred to his mineral ‘mythology’, where all possible permutations of the sexes have a place, as in a Mendeleyev table. But Roger Caillois’ interest in myths and the notion of gender, which is found in early texts from his youth, crops up unchanged in those from his maturity, such as Le Fleuve Alphée, and the precious, rare fictions, like ‘Récit du délogé’. To sum up in a word his intellectual journey, in the beginning there was stone, at the end stone remained. Within that parenthesis the space of sex and its myths unfolded.
