The Codices of San Andrés Tetepilco

Three new Aztec codices have been discovered! They were kept by a family who considered themselves the stewards of traditional knowledge in Culhuacan and Iztapalapa, formerly a distinct region that is now within the Mexico City megalopolis. They have now been donated to National Institute of Anthropology and History of Mexico. The whole press conference at which this was announced is on YouTube; English summary here.

The first is called Map of the Founding of Tetepilco, and is a pictographic map which contains information regarding the foundation of San Andrés Tetepilco, as well as lists of toponyms to be found within Culhuacan, Tetepilco, Tepanohuayan, Cohuatlinchan, Xaltocan and Azcapotzalco. The second, the Inventory of the Church of San Andrés Tetepilco, is unique, as Oudijk remarks, since it is a pictographic inventory of the church of San Andrés Tetepilco, comprising two pages. Sadly, it is very damaged.

Finally, the third document, now baptised as the Tira of San Andrés Tetepilco, is a pictographic history in the vein of the Boturini and the Aubin codices, comprising historical information regarding the Tenochtitlan polity from its foundation to the year 1603. 

I think the above is the map; all of these are screen caps from the press conference.

And this is the inventory. All of the images below come from the chronicle. More on these documents here.
