I find pre-Columbian art quite interesting. Much of it is weirdly oval and wrapped around itself. It’s not terribly naturalistic, nor is it linear. It tends to be curving and self-contained. Just a different approach from art we find in other parts of the world.
Probably all of that mostly because it presages full blown writing and is just this side of pictoglyphs. Given what we now know of PROBABLE pre-Columbian migration from East Asia to South America this art could very well be writing ~ as so much of it has been found to be.
