I've been struggling to understand some aspects of the current fad in vampire fiction, including the rivalry with werewolves. Some things are easy to see, like the relationship of vampires and young love. Vampires have always been lovers, and especially seducers. The love that is practically indistinguishable from death is a marker for intensity. The whole bloodsucking thing is a transparent sexual allegory, including the bedroom eyes, the hickey, and the usual gender associations. In this case, the intensity of the passion is expressed by the lassitude of the participants. The bloodsucker is sleepy because he's on a blood-bender, and the victim because, well, she's lost a lot of blood. What about the stake, the cross and the aversion to garlic? These are all icons of parental disapproval. The garlic is her mother's cooking, perhaps even a figure of her as a mother. The cross is the burden of parental responsibility the lovers risk incurring. The stake? That's obviously the greater sexual potency of her father, in the face of which the young vampire's urge seems to shrivel up and die, finally.
But why must vampires and werewolves be enemies? They are, after all, both unnatural monsters. So, what's the problem? Perhaps it's that the vampire is an image of dissolute desire, the aesthete, the rake. But your werewolf is more about ravenous desire, about eating, not drinking, about hunger rather than wan yearning. The werewolf seeks satiety in a feeding frenzy. In other words, he is indiscriminate in his desire. His is the desire that bears no scrutiny. This all leads to the conclusion that vampires hate werewolves because they think they are homosexuals. The vampire is a primal image of the narrowest form of homophobia.
Or maybe not. Perhaps I've completely misread this imagery. Let me know what you think.
