The volume brings together the author's texts and documentary material, including an introductory essay, bibliographic notes, analyses and editorial commentary by Guillaume Apollinaire, plus previously unpublished pieces, correspondence and a portrait. It reconstructs the writer's life from scattered documents, outlines his military service and travels, and situates his libertine stories and theatrical efforts within their publication context. Close readings emphasize recurring concerns with eroticism, social mores and self-presentation, while textual notes address variants and sources. The edition combines restoration of texts with critical apparatus to expose both familiar narratives and lesser-known documents tied to the author's oeuvre.
