Also, whether it be coincidence or not, we can also see that "Allan" can be seen as an anagram in "Amontillado.".
More symbolism is found in the name of the antagonist, Fortunato. Fortunato is and Italian name, derived from "fortune" or "fortunate." This is ironic, firstly, because Fortunato isn't fortunate at all- he is killed. With a deeper look at the story, we see that Fortunato represents fortune, which is the ultimate influence on how good or bad a man's life is. Montressor represents a common man who is unfortunate enough- as most people are. The difference between Montressor and the common men who he may be compared to is that he is able to strike back at the fortune that treats him so badly-- fulfilling man's revenge on the fate/fortune that has been so unkind to him. Here we see that the warden has become the imprisoned. After years of placing Montressor behind bars of ridicule, Fortunato had himself become restrained with the very real restraints of revenge that Montressor had placed upon him.
"He turned towards me, and looked into the eyes with two filmy orbs that distilled the rheum of intoxication." This quotation from "The Cask Of Amontillado" connotes two different ideas- about the eyes of Fortunato and about his drunkenness. The eyes of Fortunato were glazed and were dripping grossly, as it sounds. According to Poe, the eyes are the windows to the soul. If this holds true for this story, Fortunato's soul was not very clean or clear. Fortunato's drunkenness ties in with the idea of him representing fortune. If Fortunato is drunk, he's not thinking about what he's doing- how he's insulting Montressor. This shows that fortune is ambiguous. So, there are no rewards based on merit and no punishment based on evil- it's more a case of fortune being indifferent and cruel to man.
"You are a man to be missed." This quote from Montressor is one of the first instances and one of the more memorable of foreshadowing in "The Cask Of Amontillado.
