As a footnote: Jacob Bronowski has a fascinating discussion of the Mayan calendar in his classic 1973 TV series describing how science and culture coevolve, “The Ascent of Man.” One of his discussions involved the advanced Mayan astronomy and the central riddle why it existed. The attached article may well relate to or even explain that question.
