This 1913 volume traces the influence of the poet Charles Baudelaire in England and France. The author claims that without Baudelaire, "the world would in some way, great or small, have been other than it is." The book is divided into seven parts: "Development of the Baudelairian Spirit," "Baudelaire," "Predecessors of Baudelaire," "Posterity of Baudelaire," "The Baudelairian Spirit in England," "The Baudelairian Spirit in Painting," and "The Baudelairian Spirit in Music."
