“True!—nervous—very, very dreadfully nervous I had been and am; but why will you say that I am mad? The disease had sharpened my senses—not destroyed—not dulled them.”

The story’s opening lines set the tone and showcase Poe’s style. The work is written in the first person, and the entire story is told as a confession, presumably to someone in the police force. However, the fact that the narrator’s interlocutor remains anonymous allows the reader to step into their shoes, creating a sense of directness and immediacy.

“Above all was the sense of hearing acute. I heard all things in the heaven and in the earth. I heard many things in hell. How, then, am I mad?” 

This quote describes in detail the narrator’s supposed disease, which they believe has sharpened all their senses, particularly their hearing. However, it is more likely that the criminal is experiencing hallucinations, since they describe hearing things in “hell.” Additionally, the reference to hell implies unpleasant sounds, presumably of torture. It also foreshadows death. Finally, the narrator’s statement reveals their belief in their own superiority, as someone who is almost omniscient.

“I think it was his eye! yes, it was this! One of his eyes resembled that of a vulture—a pale blue eye, with a film over it. Whenever it fell upon me, my blood ran cold; and so by degrees—very gradually—I made up my mind to take the life of the old man, and thus rid myself of the eye for ever.”

The description of the eye is vivid and repetitive, suggesting a fear of disease and old age. The use of the word “vulture” brings to mind death and decay. Additionally, the film over the eye is a clear sign of disease usually associated with old age. Thus, the narrator’s irrational fear of death and disease is expressed through his hatred of the old man’s eye.
