It is well known that the calendar common to the Aztecs and Mayas divides the month into four weeks, each containing a like number of secular days; that their indiction is divided into four periods; and that they believed the world had passed through four cycles. It has not been sufficiently emphasized that in many of the picture writings these days of the week are placed respectively north, south, east, and west, and that in the Maya language the quarters of the indiction still bear the names of the cardinal points, hinting the reason of their adoption.[74-1] This cannot be fortuitous. Again, the division of the year into four seasons--a division as devoid of foundation in nature as that of the ancient Aryans into three, and unknown among many tribes, yet obtained in very early times among Algonkins, Cherokees, Choctaws, Creeks, Aztecs, Muyscas, Peruvians, and Araucanians. They were supposed to be produced by the unending struggles and varying fortunes of the four aerial giants who rule the winds.
We must seek in mythology the key to the monotonous repetition and the sanctity of this number; and furthermore, we must seek it in those natural modes of expression of the religious sentiment which are above the power of blood or circumstance to control. One of these modes, we have seen, was that which led to the identification of the divinity with the wind, and this it is that solves the enigma in the present instance. Universally the spirits of the cardinal points were imagined to be in the winds that blew from them. The names of these directions and of the corresponding winds are often the same, and when not, there exists an intimate connection between them. For example, take the languages of the Mayas, Huastecas, and Moscos of Central America; in all of them the word for _north_ is synonymous with _north wind_, and so on for the other three points of the compass. Or again, that of the Dakotas, and the word _tate-ouye-toba_, translated "the four quarters of the heavens," means literally, "whence the four winds come."[75-1] It were not difficult to extend the list; but illustrations are all that is required. Let it be remembered how closely the motions of the air are associated in thought and language with the operations of the soul and the idea of God; let it further be considered what support this association receives from the power of the winds on the weather, bringing as they do the lightning and the storm, the zephyr that cools the brow, and the tornado that levels the forest; how they summon the rain to fertilize the seed and refresh the shrivelled leaves; how they aid the hunter to stalk the game, and usher in the varying seasons; how, indeed, in a hundred ways, they intimately concern his comfort and his life; and it will not seem strange that they almost occupied the place of all other gods in the mind of the child of nature. Especially as those who gave or withheld the rains were they objects of his anxious solicitation. "Ye who dwell at the four corners of the earth--at the north, at the south, at the east, and at the west," commenced the Aztec prayer to the Tlalocs, gods of the showers.[75-2] For they, as it were, hold the food, the life of man in their power, garnered up on high, to grant or deny, as they see fit. It was from them that the prophet of old was directed to call back the spirits of the dead to the dry bones of the valley. "Prophesy unto the wind, prophesy, son of man, and say to the wind, thus saith the Lord God, come forth from the four winds, O breath, and breathe upon these slain, that they may live." (Ezek. xxxvii. 9.)
