Abstract: C.T. Dreyer stated that his silent masterpiece of 1932, Vampyr, had been inspired by the works of J.S. Le Fanu, and criticism has indeed found many elements in common between Vampyr and Le Fanu's tales, most notably his 1872 novella Carmilla. In my lecture, I will analyse an element that has so far been largely overlooked, namely the presence of imaginary or literarily transfigured books in both works. While, in Carmilla, the reader is presented with a small sylloge of book titles - mostly picked from Augustin Calmet's eighteenth-century treatise on vampirism -, in the case of Vampyr a strongly diegetic role is played by a fictitious book, entirely invented and perhaps written by Dreyer himself, which was equally inspired by Calmet's work: 'Paul Bonnat''s Die seltsame Geschichte der Vampyre/Histoire curieuse des vampires. I will show how this intertextual presence of real texts and pseudobiblia in the two works enables to discern a pattern that ties Carmilla and Vampyr more closely, connecting them to the archaeology of vampire beliefs. More specifically, I will show how Calmet's model invited Le Fanu and Dreyer to merge the literary figure of the vampire and the belief in incubi and succubi in premodern Europe.
