The Vampyre; a Tale by John William Polidori

****.
During the snowy summer of 1816, the "Year Without A Summer," the world was locked in in a long cold volcanic winter responsible for the deaths of million, caused by the eruption of Tambora in 1815. In this terrible year, Mary Wollstonecraft Shelley and her husband Percy Bysshe Shelley visited Lord Byron in Switzerland. After reading an anthology of German ghost stories, Byron challenged the Shelleys and his personal physician John William Polidori to each compose a story of their own. Of the four, only Polidori completed a story, though Mary conceived an idea, and this was the germ of Frankenstein.


It is worth noting that Byron managed to write a fragment based on the vampire legends he heard while traveling the Balkans. Polidori used this fragment to create the novel The Vampyre (1819), which is the origin of all subsequent vampire literature. Thus, the Frankenstein and vampire themes were created from that single circumstance.
