THE LITERATURE OF MEXICAN RELIGION
It is necessary at this stage to deal briefly with the sources of Mexican religious history. A literature, bewildering in its scope and variety, has grown up around the subject of Mexican antiquity as a whole, and it is perhaps well for the student if he approaches it with only a partial realization of the spacious character of the material he must review. I have thought it best in such a work as this to relegate most of the bibliographical matter to an appendix, where an endeavour has been made to supply the student with a trustworthy catalogue of such manuscripts and works as are essential to the study of Mexican religion. It is hoped that this may prove of guidance and assistance and spare much initial toil. But for the present I will confine my remarks to such general observations upon the sources from which we partly glean our knowledge of the ancient Mexican faith as will serve the immediate purpose. These sources are four in number: (I) The native codices or paintings; (II) the native annals; (III) native art-forms in architecture, sculpture, pottery, and mural painting, depicting gods and other divine beings; and (IV) the writings of the Spanish conquerors of Mexico.
(I) The Native Codices.—These are paintings executed by native Mexican artists upon agave paper, leather, or cotton. Through the misguided zeal of the early Spanish religious authorities, who regarded them as of diabolic character, only some twelve of these remain to us, the greater number of which possess a mythological or religious significance. In their pages we find representations of many of the principal deities of the Mexican pantheon, as well as illustrations of several passages in Mexican myth, and they frequently depict the tonalamatl or priestly Book of Fate, with its highly complex symbolism.4 Close familiarity with these manuscripts is indispensable, as they constitute one of the few original sources of our knowledge of the aspect, costume, and insignia of the Mexican deities. All of them have been handsomely, if expensively, reproduced, and these are detailed in the bibliography.
