Still, among the first writers of the colonial epoch we shall encounter some authentic material regarding the ancient Indians. Some chroniclers based their narratives upon hieroglyphs, which they did not limit themselves to interpreting, but which also served them as a foundation for more extended records; contemporaries of the Conquest, they had heard from the conquered themselves, their traditional history. Others, without availing themselves of the assistance of the paintings, simply recorded the traditions in their works--and we must remember that, on account of the inadequacy of their hieroglyphic writing, the Mexicans were ever accustomed to carry the glorious deeds of their race in memory, which they taught their children, in song and story, that they might not be forgotten. Without doubt, the first works of the chroniclers suffered from the natural vagueness which is felt in expressing new ideas. They are not, and could not be, complete treatises because each wrote merely what he himself could gather. The most important personages of the vanquished people dead, in fighting for their country, few remained who knew the secrets of their history, and the greater number of these did not lend themselves to their revelation. The chroniclers, themselves, concealed something of what they learned, especially if it related to the gods and the religious calendar, for fear of reawakening the barely dormant idolatry. Also from the very first, the desire to harmonize the beliefs of the Indians, and their traditions, with the Biblical narrative, was, in part, responsible for the confusion in their writings; a desire very natural in that epoch, and which must be taken into account in reading the chronicles, in order to get rid of false judgments born from it. But whatever may be their defects, it cannot be denied that they constitute a most precious material, in which, seeking discreetly and logically, abundant historic treasures are encountered. We present, therefore, some discussion of the principal chroniclers and their relative importance and examine impartially the works of our historians. THE SURRENDER OF CUAUHTEMOC.
