Answer:
The literary element that Fortunate represents is Irony.
Explanation:
In Edgar Allan Poe's short story "The Cask of Amontillado", story is told by a narrator by the name Montressor who feels aggrieved and insulted by Fortunate and carefully plans his revenge.
Montressor plans to have his revenge on the evening of a carnival and lures Fortunate into the vault under the guise of tasting the rare Amontillado wine and getting his expert opinion.
Montressor disguises himself so he won't be discovered and off they went.
Ironically, when Fortunate is too drunk to continue on the journey, Montressor gives him a sip of Médoc wine to ward off the cold, thereby helping to keep him alive, just for him to bury him alive in the vault.
As Fortunate drinks the Médoc, he toasts to Montressor's buried ancestors, and Montressor toasts to Fortunate's "long life".
These two toasts are in complete irony because of what was about to happen, Montressor was about to bury Fortunate with his ancestors and the wish of long life was also irony because he would be buried alive only a few moments later.
