The images are pages from a 16th-century Aztec codex known as the Codex Borbonicus or Codex Cihuacoatl, which documents the Aztec calendar, rituals, and deities. The images are painted on amate paper, which is made from the bark of a fig tree, and show a combination of pictorial and hieroglyphic writing. This codex provides valuable insight into the complexity of Aztec culture and the importance of religion and astronomy in their lives.
