Jacula was the eponymous vampire in an Italian fumetti comic book that was also published in France as a bande dessinée. A whopping 327 issues of Jacula were produced between 1969 and 1982.
Together with her vampire husband Carlo Verdier, the predatory Jacula seduces the unwary and corrupted the innocent. She was also married to a human called Torlin Novak, and the relationship resulted in a child whose soul was promptly pledged to Satan.
Other Italian figures from the same era, and with similarly violent or erotic preoccupations, include Zora la Vampira, Lucifera, Biancaneve, Vartan, Jolanda de Almaviva, Sukia, and Yra.
