Edgar Allan Poe,
The Philosophy of Composition
(1846)
“ I had now gone so far as the conception of a Raven, the bird of ill-omen, monotonously repeating the one word "Nevermore" at the conclusion of each stanza in a poem of melancholy tone, and in length about one hundred lines. Now, never losing sight of the object - supremeness or perfection at all points, I asked myself - "Of all melancholy topics what, according to the universal understanding of mankind, is the most melancholy?" Death, was the obvious reply. ”
