|Thanks to the writings of the Spanish Colonial historians, we know that the Mixtec nobles:
had many books
that the historians inscribed with characters so abbreviated, that a single page expressed the place, the site, province, year, month, and day with all the names of the gods, ceremonies, and sacrifices, or victories that they celebrated, and recorded in this way by the sons of the lords
their priest had instructed them since infancy to illustrate the characters and memorize the histories
I heard some elders explain that they were accustomed to fasten these manuscripts along the length of the rooms of the lords for their aggrandizement and vanity, they took pride in displaying them in their councils."
(Friar Francisco de Burgoa, A.D. 1674)
