The mythologies of America are chiefly of interest because they illustrate and supplement the faiths of the Old World, and this is especially the case with the mythology of Mexico, which represents a phase of religious evolution considerably more advanced than the beliefs of the red man of the North American plains or the barbarians of the South American continent. In ancient Mexico we have one of the only three American mythological systems which attained anything like religious cohesion, or exemplified the higher reaches of ethical religious thought. The religion of ancient Mexico has been classified as a religion of the lower cultus, but the folly of such a classification is extreme, and it has, of course, emanated from persons who have made no especial study of the mythology of Mexico. To range it with such religions as those of the aborigines of Australia or those of some African tribes is incorrect, as a brief account of it will prove to the reader.
When the Spaniards finally conquered Mexico the more intelligent among them, although for the most part military men and priests, began to interest themselves in the antiquities and religion of the people they had conquered. The accounts they have left of the Aztec faith are, of course, unscientific, but we can gather a great deal from them by analogy and comparison with Old World faiths. We find that the Aztec population of Mexico worshipped gods who, if they did not form a pantheon or hierarchy, had each a more or less distinct sphere of his own. One of these, Tezcatlipoca, has been called the Jupiter of the Aztec pantheon, and seems to deserve this name.
Bernal Diaz, one of the Spanish conquerors, describes this god as having the face of a bear, and this error has been handed down from generation to generation of writers on Mexican mythology, is repeated in books of reference, and is generally accepted because of its antiquity. As I have shown elsewhere (_Edinburgh Review_ for October 1920), Tezcatlipoca was probably a development of the obsidian stone, which was employed for the purpose of making both sacrificial knives and polished mirrors in which future events were supposed to be viewed. This stone, too, was regarded as capable of raising wind or tempests. Tezcatlipoca was supposed to rush through the highways at night, and in this connexion he probably symbolized the night wind, but from analogy with other North American Indian gods of a like character it is most probable that in later times he came to be thought of as a personification of the breath of life. The wind is usually regarded as the giver of breath and the source of immediate life. One of Tezcatlipoca's names was Yoalli Ehecatl, or Night Wind, and this leads us to suspect that he was the giver of all life. In many mythologies the name of the chief deity is derived from the same root as the word 'wind,' and in others the words 'soul' and 'breath' have a common origin. Thus the Hebrew word _ruah_ is equivalent to both wind and spirit, as is the name of the Egyptian god Kneph. Strangely enough, however, Tezcatlipoca was also regarded as a death-dealer, and some of the prayers addressed to him are pitiful in their tone of entreaty that he will refrain from slaying his devotees. The probable reason for this is that his worship, however it became so, was so extremely popular as almost to eclipse most other Mexican deities, and owing to this popularity his idea achieved such an enormous significance in the Aztec mind that he began to be regarded as a god of fate and fortune with power to ban or bless as he saw fit, and therefore to be sedulously placated by prayer and sacrifice.
