The Spectacles can be considered as a double of “the Man who was Used up” as it has all its main characteristics.
Both stories are based on the search for truth and the final revelation. The revelations then have a common denominator of horror. When the narrator of The Spectacles discovers the mystery and realizes that he has married not a beautiful girl but an old caryatid, he experiences the same horror reaction as the narrator of The Man who was Used up in front of his mutilated “bundle”. Horror seems to be an almost inseparable component of Poe’s production.
