Then, methought, the air grew denser, perfumed from an unseen censer
Swung by Seraphim whose foot-falls tinkled on the tufted floor.
"Wretch," I cried, "thy God hath lent thee - by these angels he has sent thee
Respite - respite and nepenthe from thy memories of Lenore!
Quaff, oh quaff this kind nepenthe, and forget this lost Lenore!"
Quoth the raven, "Nevermore."

Edgar Poe. Raven
