While most authorities agree as to the character of the destructions which terminated the suns, they vary much as to their sequence. Water, winds, fire, and hunger, are the agencies, and in one Codex (Vaticanus) occur in this order. Gama gives the sequence, hunger, winds, fire, and water; Humboldt hunger, fire, winds, and water; Boturini water, hunger, winds, fire. As the cycle ending by a famine, is called the Age of Earth, Ternaux-Compans, the distinguished French _Américaniste_, has imagined that the four Suns correspond mystically to the domination exercised in turn over the world by its four constituent elements. But proof is wanting that Aztec philosophers knew the theory on which this explanation reposes.
Baron Humboldt suggested that the suns were "fictions of mythological astronomy, modified either by obscure reminiscences of some great revolution suffered by our planet, or by physical hypotheses, suggested by the sight of marine petrifactions and fossil remains,"[216-1] while the Abbé Brasseur, in his late works on ancient Mexico, interprets them as exaggerated references to historical events. As no solution can be accepted not equally applicable to the same myth as it appears in Yucatan, Peru, and the hunting tribes, and to the exactly parallel teachings of the Edda,[216-2] the Stoics, the Celts, and the Brahmans, both of these must be rejected. And although the Hindoo legend is so close to the Aztec, that it, too, defines four ages, each terminating by a general catastrophe, and each catastrophe exactly the same in both,[216-3] yet this is not at all indicative of a derivation from one original, but simply an illustration how the human mind, under the stimulus of the same intellectual cravings, produces like results. What these cravings are has already been shown.
The reason for adopting four ages, thus making the present the fifth, probably arose from the sacredness of that number in general; but directly, because this was the number of secular days in the Mexican week. A parallel is offered by the Hebrew narrative. In it six epochs or days precede the seventh or present cycle, in which the creative power rests. This latter corresponded to the Jewish Sabbath, the day of repose; and in the Mexican calendar each fifth day was also a day of repose, employed in marketing and pleasure.
