Edgar Allan Poe,
The Raven
(1845)
“ His artistic introduction of a third rhyme in both the second and fourth lines, and the addition of a fifth line and a final refrain, made the stanza of The Raven. The persistent alliteration seems to come without effort, and often the rhymes within lines are seductive; while the refrain or burden dominates the whole work. Here also he had profited by Miss Barrett's study of ballads and romaunts in her own and other tongues. A "refrain" is the lure wherewith a poet or a musician holds the wandering ear,—the recurrent longing of Nature for the initial strain. ”
