Read it through once

From this epoch the lover no longer jests—no longer sees anything even of the fantastic in the Raven’s demeanour. He speaks of him as a “grim, ungainly, ghastly, gaunt, and ominous bird of yore,” and feels the “fiery eyes” burning into his “bosom’s core.” This revolution of thought, or fancy, on the lover’s part, is intended to induce a similar one on the part of the reader—to bring the mind into a proper frame for the dénouement—which is now brought about as rapidly and as directly as possible.
