The Gold-Bug
The essay is important in that it predicts some general motifs of modern science fiction. Poe also was beginning to create an analytic method that would eventually be used in his "tales of ratiocination", the earliest form of a detective story, "The Gold-Bug" and "The Murders in the Rue Morgue". This point is furthered in that Poe particularly emphasized that a "mind" was operating the machine.
