Got it! I understand what you're saying. :thumbsup: Your point is well taken, prior use does not guarantee continued use, and you're primarily interested in the 1700s and 1800s in this discussion, thus my observation that the chair style was common in the middle ages is quite irrelevant. Sorry, bad academic trait; arguing about some trifle point that isn’t at all relevant to main question. :redface:
But since you mentioned the Renfair crowd, just a side comment: To those of us who do serious academic study of any aspect of the middle ages (in my case medieval astronomy specifically, but I’ve studied medieval history seriously for 25+ years), the SCA and RenFair people are joke. Their version of “medieval PC” usually makes the lowest-budget Hollywood “mountain man” film look like a documentary. :rotf: I wouldn't take their accepting or not accepting something as period correct as worth a hill of beans, to put it politely.
