"The Vampyre" is a short work of prose fiction written in 1819 by John William Polidori as part of a contest between Polidori, Mary Shelley, Lord Byron, and Percy Shelley. The same contest produced the novel Frankenstein; or, The Modern Prometheus. The Vampyre is often viewed as the progenitor of the romantic vampire genre of fantasy fiction. The work is described by Christopher Frayling as "the first story successfully to fuse the disparate elements of vampirism into a coherent literary genre."
"The Vampyre" was first published on 1 April 1819 by Henry Colburn in the New Monthly Magazine with the false attribution "A Tale by Lord Byron". The name of the work's protagonist, "Lord Ruthven", added to this assumption, for that name was originally used in Lady Caroline Lamb's novel Glenarvon (from the same publisher), in which a thinly-disguised Byron figure was named Clarence de Ruthven, Earl of Glenarvon. Despite repeated denials by Byron and Polidori, the authorship often went unclarified.https://en.wikipedia.org/wiki/Vampire
Vampiric entities have been recorded in most cultures; the term vampire was popularized in Western Europe after reports of an 18th-century mass hysteria of a pre-existing folk belief in the Balkans and Eastern Europe that in some cases resulted in corpses being staked and people being accused of vampirism. Local variants in Eastern Europe were also known by different names, such as shtriga in Albania, vrykolakas in Greece and strigoi in Romania.https://en.wikipedia.org/wiki/Werewolf
Slavic uses the term vlko-dlak (Polish wilkołak, Czech vlkodlak, Slovak vlkolak, Serbo-Croatian вукодлак - vukodlak, Slovenian volkodlak, Bulgarian върколак/vrkolak, Belarusian ваўкалак/vaukalak, Ukrainian вовкулака/vovkulaka), literally "wolf-skin", paralleling the Old Norse ulfhéðinn. However, the word is not attested in the medieval period. The Slavic term was loaned into modern Greek as Vrykolakas. Baltic has related terms, Lithuanian vilkolakis and vilkatas, Latvian vilkatis and vilkacis. The name vurdalak (вурдалак) for the Slavic vampire ("ghoul, revenant") is a corruption due to Alexander Pushkin, which was later widely spread by A.K. Tolstoy in his novella The Family of the Vourdalak (composed in French, but first published in a Russian translation in 1884).
