Nope. I don't pretend to. Don't even know which priest. Or what a Jesuit priest would bother to "codify" in the first place.
But I know the hand of nature and it's all over those rocks.
Heck, we only knew about 5% of Old Mayan until it was "cracked" in the 1950's. Why bother further encoding if their "plain text" is near indecipherable.
