Calmet’s Dissertation on Ghosts and Vampires first appearing in the mid-18th century was the definitive textbook on such creatures for centuries.  Here he gathers together the most learned examples of black magic, spectral beings and the recent craze around Vampires emerging from eastern Europe.  His book greatly popularized and informed vampire lore and was popular enough to be translated into English where it would go on to inform the explosion of Vampire literature, including Stoker’s Dracula.  An important textbook on the occult, this edition is the expanded text.  Featured in the Esoterica episode on early vampires.  I can also include an edition of the 1850 English translation if interested - really THE book on Vampires.
