Where were the Aztecs located?
Teotihuacan Teotihuacan , also written Teotihuacán (] ,    ), is an ancient Mesoamerican city located in a sub-valley of the Valley of Mexico, located in the State of Mexico 40 km northeast of modern-day Mexico City, known today as the site of many of the most architecturally significant Mesoamerican pyramids built in the pre-Columbian Americas.
Huehueteotl Huehueteotl ; ] is an aged Mesoamerican deity figuring in the pantheons of pre-Columbian cultures, particularly in Aztec mythology and others of the Central Mexico region. The spellings Huehuetéotl and Ueueteotl are also used. Although known mostly in the cultures of that region, images and iconography depicting Huehueteotl have been found at other archaeological sites across Mesoamerica, such as in the Gulf region, western Mexico, Protoclassic-era sites in the Guatemalan highlands such as Kaminaljuyú and Late-Postclassic sites on the northern Yucatán Peninsula (Miller and Taube, 1993:189). The name Huehueteotl stems from Nahuatl "huēhueh" ] ("old") and "teōtl" ] ("god"). It seems to connect the Old God to certain Mayan deities called "Mam" ("Grandfather").
