with a high collar introduced by playwright Hamilton Deane to help Dracula 'vanish' on stage. Lord Ruthven and Varney were able to be healed by moonlight, although no account of this is known in traditional folklore. Implied though not often explicitly documented in folklore, immortality is one attribute which features heavily in vampire film and literature. Much is made of the price of eternal life, namely the incessant need for blood of former equals. Literature The vampire or revenant first appeared in poems such as The Vampire (1748) by Heinrich August Ossenfelder, Lenore (1773) by Gottfried August Bürger, Die Braut von Corinth (The Bride of Corinth) (1797) by Johann Wolfgang von Goethe, Robert Southey's Thalaba the Destroyer (1801), John Stagg's "The Vampyre" (1810), Percy Bysshe Shelley's "The Spectral Horseman" (1810) ("Nor a yelling vampire reeking with gore") and "Ballad" in St. Irvyne (1811) about a reanimated corpse, Sister Rosa, Samuel Taylor Coleridge's unfinished Christabel and Lord Byron's The Giaour. Byron was also credited with the first prose fiction piece concerned with vampires: "The Vampyre" (1819). This was in reality authored by Byron's personal physician, John Polidori, who adapted an enigmatic fragmentary tale of his illustrious patient, "Fragment of a Novel" (1819), also known as "The Burial: A Fragment". Byron's own dominating personality, mediated by his lover Lady Caroline Lamb in her unflattering roman-a-clef Glenarvon (a Gothic fantasia based on Byron's wild life), was used as a model for Polidori's undead protagonist Lord Ruthven. The Vampyre was highly successful and the most influential vampire work of the early 19th century. Varney the Vampire was a popular mid-Victorian era gothic horror story by James Malcolm Rymer and Thomas Peckett Prest, which first appeared from 1845 to 1847 in a series of pamphlets generally referred to as penny dreadfuls because of their low price and gruesome contents. Published in book form in 1847, the story runs to 868 double-columned pages. It has a distinctly suspenseful style, using vivid imagery to describe the horrifying exploits of Varney. Another important addition to the genre was Sheridan Le Fanu's lesbian vampire story Carmilla (1871). Like Varney before her, the vampiress Carmilla is portrayed in a somewhat sympathetic light as the compulsion of her condition is highlighted. No effort to depict vampires in popular fiction was as influential or as definitive as Bram Stoker's Dracula (1897). Its portrayal of vampirism as a disease of contagious demonic possession,
