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.
|
||
|
||
And the silken, sad, uncertain rustling of each purple curtain
|
||
Thrilled me—filled me with fantastic terrors never felt before;
|
||
So that now, to still the beating of my heart, I stood repeating
|
||
“’Tis some visitor entreating entrance at my chamber door—
|
||
Some late visitor entreating entrance at my chamber door;—
|
||
This it is and nothing more.”
|
||
|
||
Presently my soul grew stronger; hesitating then no longer,
|
||
“Sir,” said I, “or Madam, truly your forgiveness I implore;
|
||
But the fact is I was napping, and so gently you came rapping,
|
||
And so faintly you came tapping, tapping at my chamber door,
|
||
That I scarce was sure I heard you”—here I opened wide the door;—
|
||
Darkness there and nothing more.
|
||
|
||
Deep into that darkness peering, long I stood there wondering, fearing,
|
||
Doubting, dreaming dreams no mortal ever dared to dream before;
|
||
But the silence was unbroken, and the stillness gave no token,
|
||
And the only word there spoken was the whispered word, “Lenore?”
|
||
This I whispered, and an echo murmured back the word, “Lenore!”—
|
||
Merely this and nothing more.
|
||
|
||
Back into the chamber turning, all my soul within me burning,
|
||
Soon again I heard a tapping somewhat louder than before.
|
||
“Surely,” said I, “surely that is something at my window lattice;
|
||
Let me see, then, what thereat is, and this mystery explore—
|
||
Let my heart be still a moment and this mystery explore;—
|
||
’Tis the wind and nothing more!”
