Poe's The Black Cat, and Cask of Amontillado are similar in: Characterization,Setting, Presence of Macabre imagery, Gothic Elements, Symbols, the mirroring of Poe's life, psychological horror, allusions, imagery, theme, sound devices ( euphony/ cacophonous sounds), tone and mood I appreciate any input!!!
