A short-story collection arranged as a study of the merveilleux logique, testing how far scientific reason or fantasy may predominate while preserving a dual character of wonder and logic. It opens with a quasi-scientific narrative about a man rescued at sea who awakens with memory loss and proceeds through intermediate tales that gradually trade scientific explanation for mythic suggestion, ending in fable-like and legendary pieces. Across the cycle the author varies tone and method, alternating rational speculation, pseudo-scientific detail, paradoxical cosmologies, and allegorical myth, exploring the limits of the genre and the gradual transition from explanation to pure imagination.
