While walking through the catacombs, Fortunato makes a gesture to see if Montresor recognizes the symbols of the brotherhood of bricklayers. Montresor does not recognize him; however he continues to tell Fortunato that he is really a bricklayer. When Fortunato asks for a sign Montresor shows him a trowel that is used by bricklayers. Fortunato thinks it's a joke, but has no idea that Montresor will later use that trowel to wall him in his own grave. There is also verbal irony when Fortunato drinks the wine and says: “I drink to the buried who rest around us”, and Montresor replies “and I to your long life” (Poe 394). Fortunato drinks from the dead around him, but does not know that soon he too will be among the dead. Montresor toasts Fortunato's long life; however, he knows that Fortunato's life will end soon. Poe uses verbal irony throughout “A Cask of Amontillado.” In Edgar Allen Poe's gothic short story “A Cask of Amontillado” irony is used throughout the plot. The unreliable narrator is just out for revenge and uses irony to make his friend trust him. Fortunato is anything but lucky in this tale, and the use of irony in almost every element of the story creates a suspenseful tale for the protagonist.
