The most important among the former are the Mexican, for they appear to have been definitively fixed by symbolic and mnemonic paintings before any contact with Europeans. According to these documents, the Noah of the Mexican cataclysm was Coxcox, called by certain peoples Teocipactli or Tezpi. He had saved himself, together with his wife Xochiquetzal, in a bark, or, according to other traditions, on a raft, made of cypress wood (_Cupressus disticha_). Paintings retracing the deluge of Coxcox have been discovered among the Aztecs, Miztecs, Zapotecs, Tlascaltecs, and Mechoacaneses. The tradition of the latter is still more strikingly in conformity with the story as we have it in Genesis and in Chaldean sources. It tells how Tezpi embarked in a spacious vessel with his wife, his children, and several animals, and grain, whose preservation was essential to the subsistence of the human race. When the great god Tezcatlipoca decreed that the waters should retire, Tezpi sent a vulture from the bark. The bird, feeding on the carcases with which the earth was laden, did not return. Tezpi sent out other birds, of which the humming-bird only came back with a leafy branch in its beak. Then Tezpi, seeing that the country began to vegetate, left his bark on the mountain of Colhuacan. The document, however, that gives the most valuable information as to the cosmogony of the Mexicans is one known as "Codex Vaticanus," from the library where it is preserved. It consists of four symbolic pictures, representing the four ages of the world preceding the actual one. They were copied at Chobula from a manuscript anterior to the conquest, and accompanied by the explanatory commentary of Pedro de los Rios, a Dominican monk, who in 1566, less than fifty years after the arrival of Cortez, devoted himself to the research of indigenous traditions as being necessary to his missionary work. The first age is marked with the cipher 13×400+6, or 5206, which Alexander von Humboldt understands as giving the number of years of the period, and Abbé Brasseur de Bourbourg as the date of its commencement, from a proleptic era going back from the period of the execution of the manuscript. This age is called _Tlatonatiuh_, "Sun of Earth." It is that of the giants, or Quinames, the earliest inhabitants of Anahuac, whose end was destruction by famine. The number of the second age is 12×400+4, or 4804, and it is called _Tlatonatiuh_, "Sun of Fire." It closes with the descent on Earth of Xiuhteuchli, the god of fire. Mankind are all transformed into birds, and only thus escape the conflagration. Nevertheless, one human pair find refuge in a cave, and repeople the world. As to the third age, _Ehécatonatiuh_, "Sun of Wind," its number is 10×400+10, or 4010. Its final catastrophe is a terrible hurricane raised by Quetzalcoatl, the "god of the air." With few exceptions, men are metamorphosed into monkeys.
