In a remarkable archaeological endeavor, researchers have successfully recovered 16th-century Aztec codices from the site of San Andrés Tetepilco. These invaluable artifacts offer a window into the rich cultural heritage of the Aztec civilization, providing insights into their history, traditions, and societal structures.

The first codex, titled “Map of the Founding of Tetepilco,” provides information about the foundation of San Andrés Tetepilco and includes lists of toponyms within the region. The second codex, the “Inventory of the Church of San Andrés Tetepilco,” offers a pictographic inventory of the church and its assets, albeit in a damaged state. Finally, the third codex, known as the “Tira of San Andrés Tetepilco,” narrates the history of Tenochtitlan from its foundation to the early 17th century, featuring unique iconography and historical information.

Among the scenes depicted in these manuscripts is the arrival of Hernán Cortés, portrayed in the attire of a Roman centurion, symbolizing the clash of civilizations that defined this period of history.

María Castañeda de la Paz, a researcher at the Anthropological Research Institute of Mexico’s National Autonomous University (UNAM), expressed her astonishment at the rarity of such documents, emphasizing their significance in understanding the history of Tenochtitlan.The codices are crafted on amate paper with intricate details painted using natural pigments. These codices represent a fusion of indigenous traditions and European influences, featuring texts in both Nahuatl and Spanish, written in the Latin alphabet. According to historian Rafael Tena, this blending of cultures reflects the adaptability of indigenous scribes to incorporate European techniques while preserving their own artistic heritage.Baltazar Brito Guadarrama, director of the National Library of Anthropology and History (BNAH), likened the discovery of these codices to uncovering masterpieces of art. These sentiments were echoed by INAH, which described the acquisition as a milestone comparable to previous archaeological breakthroughs in Mesoamerican studies.The newly discovered codices will undergo meticulous research and conservation efforts before being made accessible to the public. These invaluable artifacts will be stored in the vaults of the National Library of Anthropology and History in Mexico City.
