The vampire is a common image in today’s pop culture, and one that takes many forms: from Alucard, the dashing spawn of Dracula in the PlayStation game Castlevania: Symphony of the Night, to Edward, the romantic, idealistic lover in the Twilight series.

In many respects, the vampire of today is far removed from its roots in Eastern European folklore. As a professor of Slavic studies who has taught a course on vampires called “Dracula” for more than a decade, I’m always fascinated by the vampire’s popularity, considering its origins—as a demonic creature strongly associated with disease.
