Glass Prism the raven

Once upon a midnight dreary, while I pondered, weak and weary,
Over many a quaint and curious volume of forgotten lore,
While I nodded, nearly napping, suddenly there came a tapping,
As of some one gently rapping, rapping at my chamber door.
Tis some visitor," I muttered, "tapping at my chamber door,
Only this and nothing more."
Ah, distinctly I remember it was in the bleak December,
And each separate dying ember wrought its ghost upon the floor.
Eagerly I wished the morrow; vainly I had sought to borrow
From my books surcease of sorrow, sorrow for the lost Lenore,
For the rare and radiant maiden whom the angels name Lenore,
Nameless here for evermore.
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.
Then the ebony bird beguiling my sad fancy into smiling,
By the grave and stern decorum of the countenance it wore,
"Though thy crest be shorn and
shaven, thou," I said, "art sure no craven,
Ghastly grim and ancient Raven wandering from the Nightly shore,
Tell me what thy lordly name is on the Nights Plutonian shore!
Quoth the Raven, Nevermore.
