The "were-jaguar" figure is especially interesting, considering what we know of the Olmec and similar pre-Columbian cultures.
It might be a statue of one of those warriors (I forget which civilization they were from) that wore jaguar skins in battle and carried those swords made of obsidian shards.
I think it was the Aztecs.
The Aztec order of the Jaguar Knights, or ocelotl, are pretty fascinating themselves.
They wielded these pretty damn badass clubs with prismatic blades of obsidian, which as you might know, is sharp enough to decapitate horses. Of course, it still handles like a club: You lift and swing it, as opposed to thrusting with it.
