Science fiction [SEP] History
Isaac Asimov and Carl Sagan considered "Somnium" the first science-fiction story; it depicts a journey to the Moon and how the Earth's motion is seen from there. Following the 17th-century development of the novel as a literary form, Mary Shelley's "Frankenstein" (1818) and "The Last Man" (1826) helped define the form of the science-fiction novel. Brian Aldiss has argued that "Frankenstein" was the first work of science fiction. Edgar Allan Poe wrote several stories considered to be science fiction, including "The Unparalleled Adventure of One Hans Pfaall" (1835) which featured a trip to the Moon. Jules Verne was noted for his attention to detail and scientific accuracy, especially in "Twenty Thousand Leagues Under the Sea" (1870).
