Why does he become increasingly agitated? The Raven

The unnamed narrator appears in a typically Gothic setting with a lonely apartment, a dying fire, and a "bleak December" night while wearily studying his books in an attempt to distract himself from his troubles. He thinks occasionally of Lenore but is generally able to control his emotions, although the effort required to do so tires him and makes his words equally slow and outwardly pacified. However, over the course of the narrative, the protagonist becomes more and more agitated both in mind and in action, a progression that he demonstrates through his rationalizations and eventually through his increasingly exclamation-ridden monologue. In every stanza near the end, however, his exclamations are punctuated by the calm desolation of the sentence "Quoth the Raven, 'Nevermore,'" reflecting the despair of his soul.

Lenore's premature death is implicitly made aesthetic, and the narrator is unable to free himself of his reliance upon her memory. He asks the raven if there is "balm in Gilead" and therefore spiritual salvation, or if Lenore truly exists in the afterlife, but the raven confirms his worst suspicions by rejecting his supplications.
