L’Eresiarca & C. is a collection of modernist short stories by Guillaume Apollinaire, blending irony, fantasy, and philosophical inquiry. The work captures early 20th-century experimental prose through surreal narratives and fragmented forms. Characters often embody paradoxes and absurdities, challenging conventional morality and logic. Themes include identity, heresy, and the boundaries of reality and fiction. Apollinaire's style anticipates later avant-garde movements, offering an original and provocative literary voice. This 1987 Italian edition contributes to the appreciation of French modernist literature within the Italian cultural context.
