Theme: The overall theme revolved around insanity. The speaker stated, "Then, methought, the air grew denser, perfumed from an unseen censer Swung by Seraphim whose foot-falls tinkled on the tufted floor ", a seraphim is an angelic creature which shows that he became delusional at some point because he was seeing things and he was smelling perfume but there was no woman present. Also, normal people do not talk to birds so it was clearly shown that he was losing his sanity.
These lines signify the time and place that the incidents in the poem were occurring (on a dreary December night at midnight)
Setting: In line one the speaker said " Once upon a midnight dreary, while I pondered, weak and weary",in line four he said "as of some one gently rapping, rapping at my chamber door, and in line seven he said "distinctly I remember it was in the bleak December"
Speaker- is melodramatic and intense
the speaker stated that he was "weak and weary" and because of this he did not get up to answer the door at first, the words weak and weary are signs of depression.
Symbol- the raven symbolizes mournful, never ending remembrance of Elenore's absence, black often times symbolize death and seeing the raven makes the speaker realize that he will never see Elenore again.
Imagery: In line 47 the speaker says "Night’s Plutonian shore" this signifies the power of nature/ how frightening the night and darkness is.
Refrain- "Then the bird said “Nevermore".” The phrase nevermore is repeated eleven times throughout the poem which signifies that Elenore is dead.
