The thesis "Stereotypes of the magnetizer and hypnotist in English fiction literature of the 19th Century" is made up of three research papers. In the first paper, entitled "The picture of Animal Magnetism in Fiction Literature: The Cases of Poe, Doyle, and Du Maurier," I discuss the following texts: The Facts in the Case of M.Valdemar (1845) by Edgar Allan Poe, The Great Keinplatz Experiment (1885) by Arthur Conan Doyle and Trilby (1894) by George Du Maurier. Thus, the case of Poe serves to present the historical overview of the diffusion and reception of animal magnetism in the United States, that of Doyle for the German case and that of Du Maurier for the British case. After these brief historical introductions, I deal with the analysis of fiction texts, their contextualization and the influences of the authors, paying special attention to the characteristics and stereotypes of the literary genre of mesmeric / hypnotic fiction. I finish the article with some general conclusions highlighting the stereotypes of the villain magnetizer and the esoteric magnetizer. In the second paper, "Hypnosis, Animal Magnetism, and Monstrosity in Late 19th Century English Literature," I discuss the novels The Beetle (1897) by Richard Marsh and Dracula (1897) by Bram Stoker. On this occasion I was interested in highlighting the relationship of animal magnetism and hypnosis with the figure of the monster (from the other, from abroad, from the deviant, the inverted, etc.) and how these monstrous characters cannot be reduce to the villain magnetizer or hypnotist stereotype, since the mesmeric and hypnotic powers work here as aggregates to shape the monstrosity of these creatures. In the third paper, "Professors, Charlatans, and Spiritists: The Stage Hypnotist in Late Nineteenth-Century English Literature" I discuss the texts Professor Fargo (1874) by Henry James and Drink: A Love Story about a Big Question (1890) by Hall Caine. In this paper, in the section dedicated to Professor Fargo (1874), highlighted some particularities of hypnosis shows in the United States, such as the fact of being closely linked or mixed with motifs and themes of the spiritualist movement; the section on the novel by Hall Caine, entitled “La Mothe against Great Hypnotist” focuses on the complaint that kept the doctors who practiced and studied hypnosis against hypnotists stage, at the same time develop some lines of research related with the subgenre of hypnotic fiction. Finally, the thesis finishes with a section of conclusions in which the main results are developed a little more extensively. Finally, after the bibliography, I have added a documentary appendix with the works that would make up the subgenre of hypnotic fiction in English literature in the 19th century.
