Read it through once

Open here I flung the shutter, when, with many a flirt and flutter, In there stepped a stately Raven of the saintly days of yore. Not the least obeisance made he; not a minute stopped or stayed he; But, with mien of lord or lady, perched above my chamber door— Perched upon a bust of Pallas just above my chamber door— Perched, and sat, and nothing more.
