Final answer:
In 'The Cask of Amontillado,' Montresor is vengeful and calculating, Fortunato is prideful, the setting is dark and claustrophobic, and the theme is the lethal pursuit of revenge as expressed through the detailed plotting of Montresor.
Step-by-step explanation:
In Edgar Allan Poe's The Cask of Amontillado, the characters of Montresor and Fortunato are depicted with intricate detail, showcasing unique personalities shaped by narrative and dialogue. Montresor, the protagonist, is portrayed as calculating and vengeful, substantiated by quotes like "At length I would be avenged", displaying his determination for revenge without risk. Fortunato, on the other hand, is depicted as proud, especially concerning his knowledge of wines, which eventually leads to his downfall.
The setting of the story is vividly described; Poe uses words and phrases like "the damp catacombs of the Montresors" to create a somber and claustrophobic atmosphere, which is enhanced by figurative language. This descriptive richness contributes to the story's eerie mood, encapsulating the reader in the same gloomy world as the characters.
One of the main themes of The Cask of Amontillado is revenge. Poe conveys this through the intricate planning and plotting of Montresor, climaxing in the literal and figurative entombment of Fortunato. The message of the inexorable and consuming nature of vengeance is communicated through this act of malicious retribution.
