The following article consists of an introduction by the first author, an annotated translation by the second, and then an analysis by the first, of the earliest known Scandinavian response to the Vampire phenomenon of Medvedia in 1732 by Nicolaus Boye, a state-employed physician residing in Stockholm. The translation shows that Boye’s own article, which constitutes a complete refutation of Johann Flückinger’s claims, was meticulously organised, abstracting and arguing against the major themes which he observed in the Visum et Repertum, while the analysis shows that Boye was working under the topical medical theories of the Dutch botanist and physician Herman Boerhaave. The analysis also demonstrates the extent to which Boye’s rationalism in refuting the Visum at Repertum is informed by his Lutheranism and belief in the Day of Judgement, and concludes by showing examples of the impact his work exerted on other academics in the 1730s.
