Boturini catalogues some forty or fifty more or less fragmentary anonymous MSS. in Nahuatl, which he had gathered together.[22] I shall recall only those whose authors he names. Some three or four historical works were written in Nahuatl by Don Domingo de San Anton Munon Chimalpain, whom I have already mentioned as an author in Spanish also. Of his Nahuatl works his _Cronica Mexicana_, which traces the history of his nation from 1068 to 1597, would be the most worthy an editor's labors. It is now in the possession of M. Aubin. The _Cronica de la muy noble y leal Ciudad de Tlaxcallan_, by Don Juan Ventura Zapata y Mendoza, cacique of Quiahuiztlan, extends from the earliest times to the year 1689. A copy of it, I have some reason to think, is in Mexico. Boturini possessed the original, and it should, by all means, be sought out and printed. The ancient history of the same city was also treated of by one of the earliest native writers, and his work, in Nahuatl, alleged to have been translated by the interpreter Francisco de Loaysa, was obtained from the latter by Boturini. An account of Tezcuco and its rulers, after the Conquest until 1564, was the work of a native, Juan de San Antonio; while Don Gabriel de Ayala, a native noble of that city, composed a history of the Tezcucan and Mexican events, extending from 1243 to 1562.[23] Of the anonymous MSS. in Boturini's list, I shall mention only one, as it alone, of all his Nahuatl records, has succeeded in reaching publication. He called it a _History of the Kingdoms of Culhuacan and Mexico_. A copy of it passed to Mexico, where it was translated by the Licentiate Faustino Chimalpopocatl Galicia, but in a very imperfect and incorrect manner. The Abbe Brasseur de Bourbourg copied the original and the translation, and bestowed on the document both a new name, _Codex Chimalpopoca_, and a whimsical geological signification. In 1879, the Museo Nacional of Mexico began in their _Anales_ the publication of the original text, this time under still another title, the _Anales de Cuauhtitlan_, with two translations, that of Galicia, and a new one by Profs. G. Mendoza and Felipe Sanchez Solis. Up to the present time, 1883, the work is not completed; but its signal importance to ancient history and mythology is amply indicated by the part in type.
