This conference is the first step in a broader project which will hopefully culminate in an edited volume. We seek to examine the longue durée history of the relationship between blood and demons and the changing nature of the relationship between demons and blood across the periods from the first century CE through until the nineteenth century CE. One of the key considerations is to examine the changing notions of demons and blood across periods and cultures. There will be a particular focus on demonic and/or supernatural realism as opposed to psychological or literary interpretations.
