1491_ New Revelations of the Americas Before Columbus - Charles C. Mann [69]
A visionary and patriot, Tlacaelel believed that the Mexica were destined to rule a vast empire. But because ambition succeeds best when disguised by virtue, he wanted to furnish the Alliance with an animating ideology—a manifest destiny, as it were, or mission civilisatrice. He came up with a corker: a theogony that transformed the Mexica into keepers of the cosmic order.
At its center was Huitzilopochtli, a martial god who wore a helmet shaped like a hummingbird’s head and carried a fire-breathing serpent as a weapon. Huitzilopochtli had long been the Mexica’s patron deity. It was he who had entered the Mexica priest’s dream to explain where to found Tenochtitlan. After the formation of the Triple Alliance, Tlacaelel “went about persuading the people,” as one Mexica historian wrote, that Huitzilopochtli was not a mere tutelary deity, but a divinity essential to the fate of humankind.
At the apex of the celestial hierarchy stood Ometeotl, the omnipresent sustainer of the cosmos, “the Lord of the Close Vicinity” in Nahuatl. In Tlacaelel’s vision, Ometeotl had four sons, one of whom was Huitzilopochtli. These four sons had been vying for supremacy since the beginning of time; the history of the universe was mainly a record of their endless struggle. At intervals the brothers would wrestle themselves into a precarious equilibrium, like sumo giants straining motionlessly against each other in the ring, with one brother on top and the other three in a temporary, isometric balance below. In these interregnums of order, Tlacaelel explained, the topmost brother linked himself to the sun, on which all living creatures depend.
In some versions of the story, the brother became the sun; in others, he merely supervised its workings. Either way, life could exist only when one brother held sway and the cosmic battle quieted and the sun was able to shine. But when the balance came apart, as it always did, the brothers would resume their strife. The sun would go dark, sinking the cosmos into an endless, lethal night. Eventually the sons would arrive at a new transitory order and reignite the sun, letting existence begin anew. This apocalyptic cycle had occurred four times before. The Mexica lived during the Fifth Sun, when the sun was identified with Huitzilopochtli.
The sun’s role was hellishly difficult, Tlacaelel said. Even when the strife among Ometeotl’s sons quieted enough to allow the sun to shine, it still had to battle the stars and moon every day as it rose in the sky—a literal struggle of light against darkness. Each day of sunlight was a victory that must be fought and won again the next day. Because the sun could not hold out forever against its foes, one sixteenth-century Nahuatl account explained, it would one day inevitably lose—there was no getting around it. “In this Sun it shall come to pass / That the earth shall move, / That there shall be famine, / And that we all shall perish.” But the calamity could be postponed, at least for a while, if the sun was fortified for its battles with the stars. To gain strength, the sun needed chalchíhuatl—the mysterious, ineffable fluid of life-energy. The sacred mission of the Triple Alliance, Tlacaelel proclaimed, was to furnish this vital substance to Huitzilopochtli, who would then use it for the sun, postponing the death of everyone on the planet.
There was but one method for obtaining this life-energy: ritual human sacrifice. To obtain the victims, Tlacaelel said (according to one of Sahagún’s contemporaries), the sun needed a “marketplace” where he
