Here is an example of how the Aztec figures from the above codex are interpreted as modern constellations as part of the work featured on this website. From the codex page above, the figure called “Chalchiuhtotolin” is featured in the top section. It is a stylized and adorned turkey. The word itself means “Jade Turkey” in Nahuatl.

  1. Draco

  4. Perseus

It may be impossible to recuperate the exact manner in which pre-Columbian people from modern-day Mexico organized the stars in the sky. Instead of lamenting over this tragic loss, we propose a creative way of addressing the issue. Aztec Astronomy shows how modern constellations can be regrouped into patterns which represent pre-Columbian icons like Quetzalcoatl, Ixnextli, the Tamoanchan and Mictlantecuhtli, among others.

The work of assigning pre-Columbian codex icons to modern constellations began in 1997 under the auspices of the Brown Berets de Aztlan ministry of education. This work was continued as independent research over the next 20 years, culminating in the publication of the series of astronomy maps entitled Aztec Astronomy.
