(II) The Native Writings.—These “annals,” as they are sometimes called, the work of natives who wrote in Spanish, constitute a mine of aboriginal information of nearly equal value with that contained in the codices, but considerable discrimination is necessary in using them in view of the tendency of their authors to corrupt traditional material when inspired by patriotic or other motives. This, however, manifestly does not apply with equal force to accounts of a mythical or ritual nature and to historical events, which offer a much greater temptation than the former to scribes manifestly ignorant of the virtues of literary integrity. The Mexican annals are of two classes: those which represent the historical or traditional relics of native communities, such as the Annals of Quauhtitlan, also known as the Codex Chimalpopocâ; and those which are the work of educated Mexicans or half-breeds, prone to magnify the splendour of the ancient races. Ranking almost as a third or separate class are the sacred songs or hymns included in the Mexican MS. of Sahagun’s Historia General, which that most unwearied of workers received at first hand from approved native scribes. The several native writings will be found described in the appendix, and the hymns, or rather a translation of them into English prose, will be met with in the descriptions of the several deities to which they apply. (III) Native Art-forms.—Mexican architectural motifs, mural paintings, and especially sculpture and pottery, frequently afford reliable material upon which to form conclusions regarding the aspect and costume of the gods, and reproductions of the most important of these illustrate the descriptions of the several Mexican deities. (IV) Writings of the Spanish Conquerors of Mexico.—If the representatives of the Church in Mexico must be condemned for their narrow and illiberal action in destroying all native manuscripts and paintings bearing upon the ancient religion of the country, certain more enlightened individuals among them laboured strenuously to remove this reproach by their zealous, if frequently unskilful, attempts to reconstruct a knowledge of the popular faith by unremitting researches into native tradition. This attitude met with but little countenance from their ecclesiastical superiors, and at times they laboured under conditions the reverse of favourable for the collection of traditional material. But it would be ungrateful not to pay a meed of respect to the self-sacrifice of those enlightened and resourceful men, but for whose endeavours our knowledge of Mexican antiquities would be all the poorer.
