This manuscript is an 18th-century copy of an original that has since been lost. It recounts the history of Mexico from 1221 to 1594. Among other events, it mentions the mythical discovery of Tenochtitlan (forerunner of Mexico City) by Cuauhcohuatl and the death of Emperor Moctezuma (also seen as Montezuma). The document is in Nahuatl, the main language of the indigenous population of Mexico. The copy was made in Mexico on paper imported from Europe, most likely by Father José Antonio Pichardo (1748−1812), who created many other copies of Mexican manuscripts held in the collections of the National Library of France.
