The Blackamoor sign represented darkness, evil, monstrosity, and Satan in England

Evidence

The Blackamoor, or Black Moor, functioned as a negative sign, representing darkness, evil, and monstrosity, much as in earlier centuries. The Blackamoor also represented Satan in the “Bag of Nails” sign, popular until the eighteenth-century. — Sophia Rose Arjana, Muslims in the Western Imagination, 325

• QUESTION: “Bag of Nails” — worth verifying the etymology and whether the pun (Bacchanals?) is the author’s or attested.
