Step-by-step explanation:
Edgar Allan Poe was the master at using a number of literary devices in his works. The Pit and the Pendulum is one of his most famous stories. In this story he sets up great suspense and a wonderful use of literary devices.
He uses vivid descriptions of things. When he wants to really make something stand out to the reader, he uses such great descriptions. The description of the torture chamber is an example of this.
He also uses symbolism throughout all of his works. The darkness of the torture chamber is a symbol of the darkness happening during the inquisition.
