Wow, that’s very scary to me that such things were completely ommitted. Funny thing is, I’ve spoken to Mexicans who have no discomfort discussing such things. Funny thing is that, historically, Europeans said the same things about their own ancestors. Europeans seem to revel in the fact that their people were conquered, in power and in faith, and forced to abandon their human-sacrificing ways, and those accounts were far less substantiated. At least that was the case for centuries.
The sad thing about all of this is that, IMO, it actually leaves the scientific advancements of such societies standing out in a no-man’s land. The Mayans developed their vast scientific and mathematical abilities in order to properly chart the movement of the heavens, largely due to the precise timing that sacrifices must occur.
As I said, it also leaves huge gaps in their art. We know that the Aztecs worshipped a god named Xipe who whore flayed human skin, and flayed skin was the very symbol of the god. Why such a bloody and common symbol from a non-bloody culture?
Again, interesting article.
