Some sixty years after the Spanish conquest of Mexico, a group of Nahua intellectuals in Mexico City set about compiling an extensive book of miscellanea, which was recorded in pictorial form with alphabetic texts in Nahuatl clarifying some imagery or adding new information altogether. This manuscript, known as the Codex Mexicanus, includes records pertaining to the Aztec and Christian calendars, European medical astrology, a genealogy of the Tenochca royal house, and an annals history of pre-conquest Tenochtitlan and early colonial Mexico City, among other topics. Though filled with intriguing information, the Mexicanus has long defied a comprehensive scholarly analysis, surely due to its disparate contents.

In this pathfinding volume, Lori Boornazian Diel presents the first thorough study of the entire Codex Mexicanus that considers its varied contents in a holistic manner. She provides an authoritative reading of the Mexicanus’s contents and explains what its creation and use reveal about native reactions to and negotiations of colonial rule in Mexico City. Diel makes sense of the codex by revealing how its miscellaneous contents find counterparts in Spanish books called Reportorios de los tiempos. Based on the medieval almanac tradition, Reportorios contain vast assortments of information related to the issue of time, as does the Mexicanus. Diel masterfully demonstrates that, just as Reportorios were used as guides to living in early modern Spain, likewise the Codex Mexicanus provided its Nahua audience a guide to living in colonial New Spain.

Created in Tepechpan, a relatively minor Aztec city in Central Mexico, the Tira de Tepechpan records important events in the city's history from 1298 through 1596. Most of the history is presented pictographically. A line of indigenous year signs runs the length of the Tira, with images above the line depicting events in Tepechpan and images below the line recording events at Tenochtitlan, capital of the Aztec empire and later the seat of Spanish rule. Written annotations amplify some of the images.

In this volume, which includes color plates of the entire Tira, Lori Boornazian Diel investigates the motives behind the creation and modification of the Tira in the second half of the sixteenth century. She identifies the Tira's different contributors and reconciles their various histories by asking why these painters and annotators, working at different times, recorded the events that they did. Comparing the Tira to other painted histories from Central Mexico, Diel demonstrates that the main goal of the Tira was to establish the antiquity, autonomy, and prestige of Tepechpan among the Central Mexican city-states that vied for power and status in the preconquest and colonial worlds. Offering the unique point of view of a minor city with grand ambitions, this study of the Tira reveals imperial strategy from the grassroots up, showing how a subject city negotiated its position under Aztec and Spanish control.
