What is an analysis of "The Cask of Amontillado"?

"The Cask of Amontillado" by Edgar Allen Poe provides several focuses for literary analysis. One analysis describes "The Cask of Amontillado" as the preeminent short story that displays Poe's dictum that every element in a well-written short story must contribute to the total effect and unity of the story.

Another analysis focuses on the story as a classic tale of revenge and subjective interpretation, which is distinguished by the pervading irony and use of dialogue as the chief structural device of the narrative. Both analyses take support from Poe's continuous in-story use of ironic visual imagery, deception, unreliable bias, irrational subjective experience and short narrative style.
