I have just finished reading Maya Cosmos: Three Thousand Years on the Shaman’s Path by David Freidel, Linda Schele, and Joy Parker. It was not an easy book to read, and it was a bit on the speculative side, but it brought forth a highly original interpretation of the fall of Classical Maya Civilization (approximately AD 250-800):
In their own way, the Maya thus acknowledged the terrible truth of war as statecraft: the authority of a small number of people over the many who must suffer and die in combat. But unlike our leaders, Maya rulers themselves went to war with the men they sent; and Maya kings and their noble vassals put not only their bodies but also their souls in jeopardy every time they clashed. It is no exaggeration to say that they lived for those moments of truth, those trials of the strength of their spirits. Every major political activity in their lives—the dedication of every public text, image, and building of royal and community importance—required the capture and sacrifice of rival peers. Only in this way could the proper rituals of sanctification be fulfilled, the gods nourished, and the portals of communication opened between the human and the divine.
When the Maya stopped inhabiting their ceremonial centers around AD 800, it wasn’t because they had disappeared: They found that there was too high a price to pay to maintain the god/kings in their position of rule. My personal belief was that certainly was one of the reasons why the Classical Civilization fell, but not the only reason
Intimately connected with the endless wars were a serious of gladiatorial combats in the form of … a ball game. Ball courts were scattered throughout Mesoamerica. At times, the games were friendly and/or ceremonial, but often they were played with the god/kings and nobles of other cities. The losing side was sacrificed to the gods. During the game, the ball could not be hit by the hands or feet: Only the thigh or hip could be used. The ball, made of rubber, was bounced against the sides of the ball court—but at no time was it allowed to touch the ground. If it did, game over—and lost.
Many a Maya god/king was sacrificed in this way, including the great 18 Rabbit of Copán, who was sacrificed at Quiriguá, which was a much smaller Maya polity.
