Aztec Codices Picture Writing We have found out a great deal about the Aztecs from studying painted manuscripts called codices. They were made up of a single sheet of paper, made from the bark of the wild fig tree or from animal parchment. The images could be painted on flat sheets which could be rolled up or on long strips which were folded like a screen. The Aztecs wrote in pictures. There were rules for drawing people.
