Who Writes History? Competing Narratives about the Conquest of Mexico and the Fall of the Aztec Empire

Butterfly-and Jaguar-Fish in Book 11 of the Florentine Codex (“On Earthly Things”). Ms. Mediceo Palatino 220, 1577, fols. 62v and 63.
"In 1577, a generation after the conquest of Mexico, a unique illustrated book was completed. Called the Florentine Codex, because it’s housed in Florence, the manuscript documents the culture, politics, natural science, and history of the Aztecs (a group of Nahuatl-speaking people who dominated large parts of central Mexico between 1428 and 1521). It does so in a period of Mexican history that was marked by great cultural transformation, social upheaval, and recurrent epidemics. The codex may be thought of as an Encyclopedia Britannica of early-modern Mexico and of Nahua knowledge. It is written in two languages, native Nahuatl and Spanish. Nahuatl, once the lingua franca of Mesoamerica, is one of 68 Indigenous languages still spoken in Mexico. It is considered an endangered language today with an estimated 1.5 million speakers. The codex is therefore not only invaluable for its content but is also an important historical record of this language. ..."
