The Codex Azcatitlan details the history of the Mexica from their migration from Aztlán to the Spanish conquest of Mexico and Christianization. The exact date it was written is not known, it is presumed it was written sometime between the mid 16th and 17th centuries.
The text consists of pictorial Aztec codex, with pictorial representations and glyphs accompanied by Nahuatl gloss, with Latin characters descriptions, the story told.
It is composed of three parts.
The first deals on an analytical mode the Aztec history since leaving the legendary Aztlán (a gloss mentions the name of Azcatitlan) in year 1-Pedernal (Flint) (gloss designated as 1168) until the Tenochtitlan founding.
The second part deals with the Aztec Tlatoanis history.
The last part, quite diverse, deals with the arrival of the Spanish and the beginnings of the conquest of the Aztec Empire.
The codex contains stylistic innovations such as volume and space suggestion, using color attenuation for this purpose. Remarkably, the drawings depict clothing folds, as well as an empirical perspective as well as composition.
Unlike most other Mesoamerican codices, the name of this codex is not one of its owners, but its contents. Indeed, it is drawn with a Gloss indicating that the place of departure of the Aztec migration is Azcatitlan (derivative of Aztlan).
It consists of 25 European paper 21 x 28 cm sheets (50 pages), painted on both sides.
All pages contain color drawings and are in excellent state of preservation. Six pages of this document are lost. The document was restored in 1959.
The codex is fastened in the European style.
The first document information is in the "Indian Historical Museum" catalogue (1702–1755) and it was owned by Lorenzo Boturini Bernaducci. This famous collector personally bought indigenous codices and when he was arrested and subsequently deported to Spain, his collection was confiscated.
