Which Aztex deity is associated with the night sky and is celebrated from May 5th to May 22nd every year during the festival of Toxcatl?
Tezcatlipoca Tezcatlipoca ( ; Classical Nahuatl: "Tezcatlipōca" ] ) 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 which were used for shamanic rituals and prophecy. Another talisman related to Tezcatlipoca was a disc worn as a chest pectoral. This talisman was carved out of abalone shell and depicted on the chest of both Huitzilopochtli and Tezcatlipoca in codex illustrations.
