At the beginning of his Creole opus The Grandissimes, George Washington Cable refers to Louisiana as "A land hung in mourning, darkened by gigantic cypresses, submerged; a land of reptiles, silence, shadow, decay". This anti-pastoral view of Louisiana as an ecosystem of horrific nature and the very human melancholy it breeds is one that has persisted in popular American culture to the present day. However, the literature of Louisiana itself is marked by its creativity in blending elements of folktales, fairy tales, and local color. This paper proposes to examine the transhuman, or the transcendence of the natural by means of supernatural transformation, in folk horror tales of Louisiana. As the locus where the fairy tale meets the burgeoning Southern Gothic, these tales revolve around a reworking of what Vladimir Propp refers to as transfiguration, the physical and metaphysical alteration of the human into something beyond the human. The focus of this paper will be on three recurring figures in Louisiana folk horror: yellow fever, voodoo, and the Devil. Drawing upon works including Alcée Fortier's collection of Creole folktales Louisiana Folktales (1895), Dr. Alfred Mercier's "1878", and various newspaper tales of voodoo ceremonies from the ante- and post-bellum periods, this article brings together theorizations about the fairy tale from Vladimir Propp and Jack Zipes and historiological approaches to the Southern Gothic genre to demonstrate that Louisiana, in its multilingual literary traditions, serves as a nexus where both genres blend uncannily together to create tales that are both geographically specific and yet exist outside of the historical time of non-fantastic fiction. Each of these figures, yellow fever, voodoo, and the Devil, challenges the expectations of what limits the human. Thus, this paper seeks to examine what will be termed the "Louisiana gothic", a particular blend of fairy-tale timelessness, local color, and the transfiguration of the human. Ultimately, the Louisiana gothic, as expressed in French, English, and Creole, tends toward a view of society in decay, mobilizing these elements of horror and of fairy tales to comment on a society that, after the revolution in Saint-Domingue, the Louisiana Purchase, and the Civil War, was seen as falling into inevitable decline. This commentary on societal decay, expressed through elements of folk horror, sets apart Louisiana gothic as a distinct subgenre that challenges conventions about the structures and functions of the fairy tale.
