It is an interesting viewpoint. I never much studies Aztec society but then again I haven't touched the Egyptian much either.
But the nice thing is that old ideas tend to be re-discovered, since they are all based upon observation of life and the universe - which changes but still seems to manifest from the same source.

d'Espagnat remarked that some part of the Veiled Reality can be seen by artists.
As for me, I take a much more egalitarian view of life. I think that it is all there to see, but it takes time to become aware of it. It reminds me of the old game show Camouflage, where a contestant had to find the tracing of a figure that is buried within a camouflage of random lines that were hiding it. It's like Where's Waldo? He is there, but it takes a while to see it.
Maybe artists are simply more evolved and more sensitive to the outlines of the puzzle. I am open to the possibility.
