Aztec codex
Appearance
Aztec codices (singular codex) are books written by pre-Columbian and Spanish colonial era Aztecs. Largely pictorial, these codices provide some of the best primary sources for Aztec and Nahuatl culture.

Boturini Codex
The Boturini Codex was painted by unknown Aztec authors some time after the Spanish conquest of Mexico. Pictorial in nature, it tells the story of the legendary Aztec journey from Aztlán to the Valley of Mexico. Rather than employing separate pages, the authors used one long sheet of paper, fan-folded into 21½ pages.
Also known as “Tira de la Peregrinación” or the “Tira de Museo”, it is named after one of its first European owners, Lorenzo Boturini Benaducci (1702 – 1751).
