So yeah, Mel Gibson is bad. But then the movies are… really good? Trying to get past his framing. The tug of war between historical accuracy and entertainment. Anthropological criticism.
The problem with burning nearly the entire written history of a people. Deciphering scant ancient texts. The remaining resources: art, stelae. Mayan hieroglyphic writing.
The Maya pre-classic, classic, and post-cassic periods. The scale of the height of Mayan civilization. The abruptness of its fall. The period in which the film takes place and the ways in which it is not actually entirely apparent. Classic-period pyramids in the post-classic era.
The mixing of astronomy and astrology in the Mayan tracking of the heavenly bodies for religious purposes. The Mayan written mathematical system. “Inventing” zero. Extensive calendaring and that whole 2012 kerfuffle.
The factors that may have contributed to the Mayan collapse. Plaster and mortar production. Deforestation for fuel.
The possibility for cultural confusion in the film. Aztec and Maya sacrificial practices.
