As is often the case in Poe's stories, the first-person narrator is not named, and he is about to be punished for an unknown crime. But unlike many of Poe's stories, we do know the time and place of this story: It takes place in Toledo, Spain, during the Spanish Inquisition. Of course, this setting and time is so far removed from the present day that the story does conform to the Romantic tradition of placing stories in some distant place and time so that there are no real identifications made. Again, Poe's story has (1) an unnamed narrator, (2) is set in the distant past, (3) concentrates upon a single effect — the effect of terror or horror by means of mental suspense, and (4) is related to many other stories by Poe's concept that in sleeping, in fainting, and, ultimately, even after death, there is a "something" that still lives and is still active, some part of the human essence ("even in the grave all is not lost" is a main idea of Poe's "Ligeia," "The Fall of the House of Usher," "The Premature Burial," and other stories).
The most unexpected aspect of the story is that it has a "happy ending"; the narrator is saved. In terms of realistic fiction, this sudden, unprepared-for rescue would be condemned as artificial or as being forced and contrived. However, the essence of Romantic fiction is the unexpected, the bizarre, and the unusual (see "Poe and Romanticism").
Furthermore, in spite of the emphasis of this story being on the unrelieved mental torture inflicted upon the narrator, who is related mentally to many of the over-sensitive heroes of the other stories (he often faints and loses control), the narrator is also akin to M. Dupin (the rationalist), in view of the fact that at the crucial moment between life and death, he gathers his mental powers together, and by putting them to use in a calm rational manner, he is able to effect his release from certain death by the pendulum.
In this story, Poe has shown himself to be a master of achieving the effect of mental torture and horror as the narrator is offered a horrible choice of death: He can plunge to death in a bottomless pit of unknown horrors filled with ravenous rats, or he can wait and be sliced up by the razor-sharp pendulum — or he can wait to be crushed by the burning hot walls closing in on him, or, finally, he can jump into the horrible pit.
