The Codex Ixtlilxochitl (ca. 1585)
The Codex Ixtlilxochitl is a composite piece comprised of three documents by at least three distinct authors. It pertains to the complex altepetl -or composite city-state- of Texcoco that, along with Tenochtitlan and Tlacopan, formed the Triple Alliance of dominant city-states we refer to today as the Aztec Empire.
It contains a ritual-calendrical portion painted in the traditional style, a detailed response to a Spanish geographical survey regarding Texcoco’s history, and an alphabetic explanation of the Aztec calendar. The first portion is possibly a copy of the same source from which the Magliabechiano emerged. Juan Bautista Pomar and Fernando de Alva Ixtlilxochitl, both mestizo (mixed-race) descendants of Texcocan nobility, produced the second and third portions, respectively. The Codex takes the name of the latter because he likely bound the three documents together.
This document (as a whole) may have been composed for self-interested purposes. In the Early Colonial period, being legally indio (“Indian”) was a privileged status in the Colonies that would have made Alva Ixtlilxochitl a direct subject of the Crown rather than of local authorities, offering a significant modicum of privilege.
