The speaker orders the raven to stop knocking at his chamber door.
The speaker is sitting up one night trying to study, depressed over a lost love. Suddenly, there is a knocking at the door. He does not know what it is at first. Finally, a raven flies in and sits on a bust. The speaker gets annoyed at the ravens continual tapping and yelling, “Nevermore!”
Leave my loneliness unbroken!—quit the bust
above my door!
Take thy beak from out my heart, and take thy
form from off my door!”
Quoth the Raven “Nevermore.”
After entreating the raven to stop several times, he gets really frustrated. He yells at the bird because it reminds him of his lost love, and his helplessness and depression. He can no more get the raven to stop knocking than he can forget about the love he lost.
"The Raven" is a poem about depression and grief. Grief for lost loved ones does not stop at sadness. It also involves anger and frustration. The speaker of this poem clearly goes through the different stages as he attemtps to come to terms with what he has lost, and get on with his life.
