Explanation:

Codices mexicas, are documents written in the Aztec colonial era; copy of lost documents dating from pre-Columbian times; These are the Borbonic Codex, the Mendocino Codex, the Pilgrimage Strip or the Boturini Codex, and Tax Registration. These codices are the best primary source of the Aztec culture, revealing the religious, social and economic life of the ancient Mexicans. These differ from the European codices in their highly pictorial content and in that they are not intended to symbolize spoken or written narratives. These codices do not have exclusively Aztec pictograms, but also classic Nahuatl, Castilian and occasionally Latin. Although there is currently access to very few codices prior to the Spanish conquest of Mexico, it is known that the trade of Tlacuilo changed considerably with the colonial culture.

this isn't a question and if you're going to list things be kind and use commas.
