Brian Aldiss has argued that Frankenstein was the first work of science fiction.[29][30] 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.[31][32] Jules Verne was noted for his attention to detail and scientific accuracy, especially in Twenty Thousand Leagues Under the Sea (1870).[33][34][35][36] In 1887, the novel El anacronópete by Spanish author Enrique Gaspar y Rimbau introduced the first time machine.[37][38]
