The worlds most famous vampire has been undead for over a century. The famous novel Dracula, written by Irish author Bram Stoker, was a mixture of reality, superstition, fearful fantasies and history. Stokers role model for the novel was an actual Romanian Prince born in the 15th century: Vlad Tepes or Vlad the Impaler, so named because of his favorite method of executing his enemies -- the horrific medieval torture known as impaling.

The image of the vampire has been seen in novels, films, plays, paintings, and even a new musical, Dance of Vampires, directed by Roman Polanski.
