Inferno is an autobiographical novel by August Strindberg. Written in French in 1896–97 at the height of Strindberg's troubles with both censors and women, the book is concerned with Strindberg's life both in and after he lived in Paris, and explores his various obsessions, including alchemy, occultism, and Swedenborgianism, and shows signs of paranoia and neuroticism. Inferno has often been cited as proof of Strindberg's own personal neuroses, such as a persecution complex, but evidence also suggests that Strindberg, although experiencing mild neurotic symptoms, both invented and exaggerated much of the material in the book for dramatic effect.
