:’) Were the glyphs deciphered at the time PT wrote his book? Because it sounds like he was just speculating. There are Mayan glyphs for Venus, the Moon, the Sun, hmm, perhaps others; I don’t think there was any Mayan interest in or even knowledge of Uranus or Neptune, let alone Pluto.
He was writing about Teotihuacan.
I don’t know about the timing with the Mayan glyphs.
The first edition is 1976.
I just looked on amazon and it is available used , hardcover cheap. I’m going to buy it, It is a great companion to his other book Secrets of the great Pyramid.
I bought the book Blam recommended Voyages of the Pyramid Builders. Tompkins books will be good paralllel reading.
I’m especially interested in the Thompkins treatment of the great pyramid and the very detailed measurements and theory of mensuration.
