I'm amazed at how often funny sculptures appear in collections of Pre-Columbian (i.e., before Columbus) art. The pictures I've been able to post here are just the tip of the iceberg. They get a lot funnier than this. The L.A. County Museum of Art has a terrific collection of funny, Virgil Parch-type sculptures, some of them more than 1500 years old. I'll post some pictures whenever I can find some good ones. You'll laugh out loud when you see them.
It's disconcerting to think that the earliest known peoples to appreciate formal comedy might have been the Central and South Americans. Among the 4 or 5 major nations only the Aztecs seemed to be serious and straight-laced about art. The others got jokes in every chance they could.
Maybe ancient South American comedy isn't better known because serious South Americans of the present are embarrassed by it. Or maybe the scuptures just don't seem like high art because they're funny. Anyway, my advice to time travelers going back to the golden age of that continent is to carry plenty of whoopee cushions and joy buzzers.
