In the "Raven" which details of the setting contribute most to the poem's mysterious and despairing mood?

"The Raven" is a dim sonnet, occurring in a dull room, on a dim night. Clearly, in light of the fact that the embodiment and emanation of death are scattered all through this ballad, the embellishments, as depicted, make this lyric. Poe portrays a bust of Pallas (Pallas Athena), showing intelligence. Poe explains on the violet velvet, and purple draperies, as purple implies honorability and variance. Be that as it may, as the storyteller is stood up to in his room by this abhorrent feathered creature, the state of mind of the ballad comes back to a dull, dreadful, tense feeling.
