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
