...But the raven, sitting lonely on the placid bust, spoke only,
That one word, as if his soul in that one word he did outpour.
Nothing further then he uttered - not a feather then he fluttered -
Till I scarcely more than muttered `Other friends have flown before -
On the morrow will he leave me, as my hopes have flown before.'
Then the bird said, `Nevermore.'...

Edgar Allan Poe
