In 18th- and 19th century Ireland, wrestling was a dangerous underground activity that police shut down wherever they could. It was like dancing in Footloose, basically. So enthusiasts would rassle on any piece of land they could find, like the infamous Donnybrook Fair (whose name literally became synonymous with uproar and disorder in the Oxford English Dictionary).

The thousands of fans who attended these events weren't content with just booing from the sidelines or throwing the occasional chair: they were as rowdy as the fighters, and matches could easily erupt into mass acts of violence. One massive skirmish left "great numbers" lying in a field with cuts and bruises, and not one arrest.
When the cops did show up to break up the fights, they had to arm themselves, often with swords, just to take on the wrestlers -- colorful characters like Dr. Brennan, an actual physician/alcohol-fueled brawler who fled on his pony when armed authorities came to interrupt one of his matches (after a fan punched a preacher). That there are no paintings immortalizing this entire scene is a crime against history and art itself.
You'll have to make do with this unrelated sketch of Irishmen and beating sticks.
