In this self-analytical text, shaped within the context of American literature, Edgar Allan Poe presents his principles for constructing a literary work, emphasizing the role of a carefully planned conception, meter, tone, and every detail. Using “The Raven” as an example, he shows how the grieving lover’s emotions, the somber nighttime setting, and the bird’s repeated reply gradually deepen the sadness and despair, creating a unified, deliberate impression in the reader’s mind.
