Today the world of vampires has changed due to a number of modern accounts on them; Twilight, The Sookie Stackhouse series (True Blood) and Interview with the Vampire and many more. Not to talk about the various TV-series following in the wake.
According to the British Library, the first vampire in English literature came with Robert Southey's epic poem Thalaba de Destroyer. The vampire takes the form of Thalaba's bride Oneiza, who dies on their wedding day.
Her very lineaments, and such as death
Had changed them, livid cheeks, and lips of blue.
But in her eyes there dwelt
Brightness more terrible
Than all the loathsomeness of death.
It seems that Southey added a very detailed footnote where he recounts the vampire tales from continental Europe. It was probably the best, otherwise people would not have understood, I guess.
