Which words in this excerpt from edgar allan poe's “the raven” give the raven a dignified and elegant appearance?
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.
