Edgar Allan Poe 
The Raven [EPUB ebook] 

First published in 1845, ‘The Raven’ by Edgar Allan Poe is a narrative poem of a young man who is bereaved by the death of the woman he loved. He compulsorily constructs self-destructive meaning around a raven’s repetition of the word ‘Nevermore’, until he finally despairs of being reunited with his beloved Lenore in another world.
Just because of the nightmarish effect, the poem cannot be called an elegy. In fact, ‘The Raven’ is a ballad of eighteen six-line stanzas with decidedly emphatic meter and rhymes.
