Just found this review at http://pelicanist.blogspot.de/2013/08/the-universal-vampire.html:
Another observation that caught my eye was that the start of popularising the vampire was, ironically enough, the Enlightenment. Leo Ruickbie gathers together what was, at that time, impressive testimony as to the actual existence of such creatures, from medical, legal and military sources. By way of a slight aside I love the Voltaire quote on p.75: “Nothing was spoken of but vampires, from 1730 to 1735“.
