Renda writes about 18th century vampires, the masticating dead, Greek vampires, the vampire tales recounted by William of Newburgh and Walter Map, related myths from antiquity, and - most notably, I suppose - archaeological finds that may (or may not) be related to beliefs in vampires and revenants. A brief appendix deals with the so-called Highgate Vampire, and a bibliography as well as a handful of maps are included.
As I do not really read Italian, I am, unfortunately, only able to get an idea of the contents based on names and references. Consequently, there may be finer points and details that are not apparent to me from scrutinizing the text based on my knowledge of the subject. No doubt this is a nice read for the Italian reader - considering, however, the brevity of the book, it looks to me as if, at best, it mainly summarizes information and views that are available elsewhere, in particular in the books that Renda himself refers to.
Revenant is available from the publisher at € 15.50 from the publisher.
