In case you're wondering like I was: the reason why a lot of the 18th-century philosophers can't seem to stop making Cato the Younger references (Voltaire talks about Cato at least 6 or 7 times in Letters on England which is a lot because it's by no means a long text. Mandeville too of course — hi bestie!)
is because there was a play in the early 1700s about Cato (Addison's Cato, a Tragedy to be precise) which seemed to have had the cultural impact of early seasons of Game of Thrones
Catoo! this actor is from an 1800s production but still. Look at that facial expression. The sad wet cat energy. The pain in his eyes. It's all there!
Oh, and by 'cultural impact of Game of Thrones' I don't mean an increase in theatre subscriptions or of Cato action figures sales (though that would have been awesome!)
I mean it had a pretty significant influence on many of the American Revolutionaries (and French too most likely, since, cultural osmosis and all that). A lot of these nerds sure loved to quote it!
