“Like evil, the vampire is a force that must be struggled with and overcome, and he thus represents [-p.3] only a single pole in a moral dyad. Whether or not we choose to label the vampire’s antagonist ‘good,’ there is not much of a story if the violence and destruction wrought by the vampire goes unchecked. While it is rare that a vampire tale or a treatment of the vampire legend does not include an episode in which the vampire is destroyed or banished by some agency, little attention has been paid to the history and character of the vampire’s personal nemesis, now popularly known as the vampire slayer.
In the elaborate heroic tales found in epics, the central theme is ordinarily the hero’s transformation in the struggle against evil (in the form, say, of a dragon) or oppression. In most vampire motifs, however, the ostensible forces of good who would identify, oppose, and destroy vampires tend to be nameless and often incidental to the narrative. In fact, it is only fairly recently that the vampire slayer has had anything like a leading role: Abraham van Helsing, in Dracula (1897), is arguably the first significant self-professed vampire slayer in a tradition that culminates in the television series Buffy the Vampire Slayer (1997-2003).” (pp.2-3)
“The heroic nature of the vampire slayer is predicated on his ability to identify the force that saps the energy from the life of the community. Something unnatural, unholy, invades and disturbs the natural order of things, and through this puncture in the tissue of everyday existence, something – is it a certain trust in the impermeability of that which separates us from the dead? – drains out. Yet because this intruder is invisible or, at the very least, unnoticeable – he is one of us, after all – only those with a special understanding of his nature are able to intervene and stop the hemorrhage. Like the vampire, the slayer must be marked – externally, by some sign of birth or accident; internally, by his symbolic connection to the world of the dead.
The nature of this bipolar relationship between the vampire and his adversary, the hunter or slayer, and the ways in which this connection becomes manifest and changes over several hundred years have not been adequately investigated. An examination of early Balkan folklore reveals that the vampire slayer, whose perceptive powers transcend those permitted ordinary Christian villagers, is the vampire’s true mirror image. The slayer is the heroic and opposing reflection that is curiously, but necessarily, generated by the presence of evil, and he is as closely bound to evil as a reflection is to its original. If the vampire is a dangerous and antihuman replica of the human, the seer or slayer is the rejector or suppressor of the replica, who restores order by allowing the community to differentiate the authentic from the false. This critical difficulty in distinguishing the true from the false, the beneficent from the treacherous, is, as we shall see, also the basis of the conflict between early Christianity and paganism and heresy. Historically, it was out of that conflict as it was played out in the Balkans that the folkloric meaning of the vampire arose.
Contemporary culture-based interpretations of the vampire ‘myth’ have great value in explaining our apparent need to continually retell the vampire story, with all its attendant variations.” (p.7)
“The linkage between the literary vampire and the folkloric one is a topic beginning to receive a great deal of attention. However, most scholars in this area take the modern vampire, especially as it has been configured since Dracula and its immediate precursors, as their starting point. They then go back into the folklore only as far as the literature itself allows, glossing over the significance of the enormous lacunae in the knowledge of vampire folklore drawn on by those earliest investigators into the subject.” (p.9)
“While folklore about vampires seems to be dying out in the Balkans as a result of the inexorable processes of westernization and urbanization, it is not clear whether the literary and cinematic vampire theme is likewise cooling down. More precisely, it is not yet clear, as of this writing, whether we are witnessing a return of the hero within the popular vampire narrative. Certainly, the success of Buffy, which makes of the slayer a complicated superhero in a fantastic suburban universe, would seem to indicate that we are becoming more interested in making the heroic primary and the vampiric evil secondary. (In Buffy, for example, almost all of the vampires and demons that are killed are more or less nameless and unsympathetic). But the low U.S. attendance figures for universal’s high-budget Van Helsing (Universal Pictures, 2004) suggest that stories of monolithic, violent vanquishers of one-dimensional monsters cannot sustain interest and in fact miss the central point of the dual nature of the vampire-slayer pair. These days, the evil that walks among us unrecognized is more often played by the sociopathic serial or mass killer, while the hero who is intuitively connected to that disturbed orientation takes the form of a forensic psychologist, or profiler. It may be that solving the problem of real evil with real (human) agents in today’s world has surpassed any need to dally with the purely imaginary.” (p.14)
