Tezcatlipoca as depicted in the Codex Borgia Tezcatlipoca was a central deity in Aztec religion, and his main festival was the Toxcatl ceremony celebrated in the month of May. One of the four sons of Ometeotl, he is associated with a wide range of concepts, including the night sky, the night winds, hurricanes, the north, the earth, obsidian, enmity, discord, rulership, divination, temptation, jaguars, sorcery, beauty, war and strife. His name in the Nahuatl language is often translated as “Smoking Mirror” and alludes to his connection to obsidian, the material from which mirrors were made in Mesoamerica and which was used for shamanic rituals.
The Codex Borgia (or Borgia Codex or Codex Yoalli Ehecatl) is a Mesoamerican ritual and divinatory manuscript. It is generally believed to have been written before the Spanish conquest of Mexico, somewhere within what is now today southern or western Puebla. The Codex Borgia is a member of, and gives its name to, the Borgia Group of manuscripts.
