Which two lines in this excerpt from Edgar Allan Poe's "The Raven" show the use of flashback?

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.
