Like all pieces of Edgar Allan Poe, The Raven is mysterious, dramatic and sorrowful, mentioning the death of a beloved Lenore. The setting is a cold winter night, at midnight, in his chamber where he must mean his grim and dark bedroom. He is trying to busy himself against thinking the death of the loved one but instead his deep emotions echo in his room.
