Cosmology
Aztec theology postulated an eternity which, however, was not without its epochs. It was thought to be broken up into a number of æons, each of which depended upon the period of duration of a separate "sun." No agreement is noticeable among authorities on Mexican mythology as to the number of these "suns," but it would appear as probable that the favourite tradition stipulated for four "suns" or epochs, each of which concluded with a national disaster—flood, famine, tempest, or fire. The present æon, they feared, might conclude upon the completion of every "sheaf" of fifty-two years, the "sheaf" being a merely arbitrary portion of an æon. The period of time from the first creation to the current æon was variously computed as 15,228, 2386, or 1404 solar years, the discrepancy and doubt arising because of the equivocal nature of the numeral signs expressing the period in the pinturas, or native paintings. As regards the sequence of "suns" there is no more agreement than there is regarding their number. The Codex Vaticanus states it to have been water, wind, fire, and famine. Humboldt gives it as hunger, fire, wind, and water; Boturini as water, famine, wind, and fire; and Gama as hunger, wind, fire, and water.
In all likelihood the adoption of four ages arose from the sacred nature of that number. The myth doubtless shaped itself upon the tonalamatl (Mexican native calendar), the great repository of the wisdom of the Nahua race, which the priestly class regarded as its vade mecum and which was closely consulted by it on every occasion, civil or religious.
