I happen to own an original Bowyer's 5 volume edition, 1806. of :
"The History of England from The Invasion of Julius Caesar to the Revolution in 1688" by
David Hume. ....."destined for the purpose of enforcing the important lessons of English History by the assistance of the FINE ARTS..."
The macro is a photo of a tiny section of the plate "Boadicea Haranguing the Britons".
I will be out of town until the 12th
