Evidence of this is provided by the 16th century Codex Mendoza, an Aztec codex written around 1541, which contains a history of the Aztec rulers and their conquests, as well as a description of the daily life of the pre-conquest Aztec community.
The codex is written in the Nahuatl language using traditional Aztec pictographs. Its name comes from Don Antonio de Mendoza, viceroy of New Spain and a leading patron of native artists.
