In the summer of 1816, the Shelleys accompanied Lord Byron and John Polidori to the manor Villa Diodati on Lake Geneva. On one particular stormy evening, the group gathered in the manor and exchanged German ghost stories. Lord Byron then proposed that everyone should write an original story. Byron wrote a vampire story titled "A Fragment." Polidori also wrote a vampire work and called it "The Vampyre." Mary Shelley, who was only 18 years old, wrote a horror tale titled "Frankenstein." Two years later, she published the story anonymously. It featured Dr. Victor Frankenstein, a scientist who becomes fascinated with the creation of life. He uses electricity and pieces from human corpses to bring a creature to life. The result was a reanimated abomination so horrific in appearance that Frankenstein rejects his creation and leaves it alone in the world. As the story progresses, the monster is repeatedly rejected by human society. He begins to seek vengeance against the world and his creator. Themes of the story include the relationship of creator and creation, the danger of scientific exploration and the role of appearance in society. It is both Mary Shelley's first novel and her masterpiece. Today, "Frankenstein" has been adapted in various forms of media dozens of times. It is considered one of the history's greatest horror tales.
