The civil polity of the Aztecs is so closely blended with their religion that without understanding the latter it is impossible to form correct ideas of their government or their social institutions. I shall pass over, for the present, some remarkable traditions, bearing a singular resemblance to those found in the Scriptures, and endeavor to give a brief sketch of their mythology and their careful provisions for maintaining a national worship. Mythology may be regarded as the poetry of religion, or rather as the poetic development of the religious principle in a primitive age. It is the effort of untutored man to explain the mysteries of existence, and the secret agencies by which the operations of nature are conducted. Although the growth of similar conditions of society, its character must vary with that of the rude tribes in which it originates; and the ferocious Goth, quaffing mead from the skulls of his slaughtered enemies, must have a very different mythology from that of the effeminate native of Hispaniola, loitering away his hours in idle pastimes, under the shadow of his bananas. At a later and more refined period, we sometimes find these primitive legends combined into a regular system under the hands of the poet, and the rude outline moulded into forms of ideal beauty, which are the objects of adoration in a credulous age, and the delight of all succeeding ones. Such were the beautiful inventions of Hesiod and Homer, “who,” says the Father of History, “created the theogony of the Greeks;” an assertion not to be taken too literally, since it is hardly possible that any man should create a religious system for his nation.[97] They only filled up the shadowy outlines of tradition with the bright touches of their own imaginations, until they had clothed them in beauty which kindled the imaginations of others. The power of the poet, indeed, may be felt in a similar way in a much riper period of society. To say nothing of the “Divina Commedia,” who is there that rises from the perusal of “Paradise Lost” without feeling his own conceptions of the angelic hierarchy quickened by those of the inspired artist, and a new and sensible form, as it were, given to images which had before floated dim and undefined before him? The last-mentioned period is succeeded by that of philosophy; which, disclaiming alike the legends of the primitive age and the poetical embellishments of the succeeding one, seeks to shelter itself from the charge of impiety by giving an allegorical interpretation to the popular mythology, and thus to reconcile the latter with the genuine deductions of science.
