Quote. "The party assembled at the Villa Diodati on Lake Geneva — Byron, Percy and Mary Shelley, John Polidori, Claire Clairmont — was confined indoors by weather it could not explain. The ghost-story competition that produced Frankenstein; or, The Modern Prometheus and The Vampyre (Polidori's text, the founding document of the modern vampire genre) was a direct response to that confinement." I thought vampires were invented by Bram Stoker.

 

Good question, and the common attribution to Bram Stoker is understandable — Dracula (1897) is the work that fixed the vampire in modern popular culture and supplied most of the conventions later media inherited (the Transylvanian Count, the vampire hunter, the specific death-by-stake-and-sunlight machinery, the seductive aristocratic predator preying on Victorian women). When people say "vampires were invented by Stoker," they usually mean something narrower than the literal claim: Stoker invented the vampire — the one the twentieth century recognised.

But vampires substantially predate Stoker, both as folklore and as literature.

Folklore. Vampiric revenants appear in many traditions long before any English literary treatment — Slavic upir, Greek vrykolakas, Romanian strigoi, and various other Eastern and Central European folk figures. The early-eighteenth-century vampire panics in Serbia and East Prussia (the Arnold Paole and Peter Plogojowitz cases of the 1720s–30s) were investigated by Habsburg officials and produced documents that circulated widely in Western Europe, introducing the word "vampire" into English (1734) and French. Dom Augustin Calmet's Treatise on the Apparitions of Spirits and on Vampires (1746) was a serious eighteenth-century scholarly engagement with the phenomenon.

Literary vampires before Stoker. This is the substantive correction:

• John Polidori, The Vampyre (1819) — written at the Villa Diodati in summer 1816, published 1819. This is the founding document of the modern literary vampire as an aristocratic, seductive, socially mobile predator (Lord Ruthven, modelled partly on Byron). Before Polidori, literary vampires were peasant revenants from folklore. After Polidori, the vampire is an aristocrat who moves in society. Every subsequent vampire-as-seductive-aristocrat, including Stoker's Count, descends from this template.
• James Malcolm Rymer (or Thomas Preskett Prest), Varney the Vampire (1845–47) — a penny dreadful that ran for 220 chapters and established many later conventions (fangs leaving puncture wounds, supernatural strength, sympathetic vampire who hates his condition).
• Sheridan Le Fanu, Carmilla (1872) — published 25 years before Dracula, a sophisticated novella about a female vampire that Stoker explicitly drew on. The "vampire hunter expert in folklore" figure, the central European Gothic setting, and several plot elements appear here first.

So the accurate version is: Polidori created the modern literary vampire template in 1819, the genre developed substantially over the nineteenth century, and Stoker in 1897 produced the synthesis that became culturally dominant and absorbed (to most readers' minds) everything that preceded it.

My phrasing — "the founding document of the modern vampire genre" — was defensible but could fairly be challenged as overstated if "modern" is read to mean "post-Stoker." If "modern" means "literary as opposed to folkloric, aristocratic as opposed to peasant, the template that subsequent writers including Stoker built on," then Polidori's The Vampyre genuinely is the founding document. The Villa Diodati attribution is solid: Polidori conceived the story there in summer 1816 during the Tambora-induced confinement, the same competition that produced Mary Shelley's Frankenstein.

Stoker's claim is more accurately stated as: he wrote the vampire novel that defined the genre for the twentieth century and beyond. That is a substantial achievement, but it is not invention.
