One of the earliest refutations of the Visum et Repertum (1732) by Johann Flückinger was from Johann Wilhelm Nöbling, a young student of philosophy and theology at the University of Jena, who attacked the findings from a position of scientific scepticism enshrouded with Lutheran theology in his thesis Concerning the Blood-Sucking Corpses of those so-called Vampires or People-Suckers. While he is best remembered for first proposing the incubus or nightmare of sleep paralysis as being the real cause of the superstition, his major contribution was theological, concerning the relation between body and soul. And yet while Nöbling provides a rigorous, scripture-based denial of vampirism, his framework necessarily accommodates contemporary medical theory, demonstrating both the adaptation of theology to science and the extent to which pneumatology still inhered in scientific enquiry.
