Final answer:
In 'The Cask of Amontillado,' Fortunato is led to believe they are in the catacombs for a rare wine, while Montresor's true motive is revenge.
Step-by-step explanation:
The two men in question are Montresor and Fortunato from Edgar Allan Poe's short story The Cask of Amontillado. Fortunato believes they are in the catacombs beneath Montresor's palazzo in search of a rare wine, the Amontillado. He is convinced by Montresor's pretense of valuing his opinion on the authenticity of the wine. However, Montresor has a sinister ulterior motive for bringing Fortunato to the damp catacombs; he seeks revenge for an undisclosed insult and plans to entomb Fortunato alive within the walls of the vaults.
