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.`
–Edgar Allan Poe
