Teotihuacán artisan workshops predominated Elsewhere, distinct ethnic enclaves are evident, most notably, a cluster of some dozen compounds evidently inhabited by Oaxacans from Monte Albán A “merchant’s neighborhood” has been identified near the city’s eastern perimeter Throughout much of the city, however, it is difficult to identify specific qualities that defined its spatial demographics While the remnants of walls can be found in various parts of the city, there is no evidence that the city as a whole was walled An estimated two-thirds of the city’s inhabitants worked in agriculture, in the fields surrounding city, with the remainder engaged in various types of craft production The inhabitants of Teotihuacán employed a system of notational signs but had no system of writing comparable to the Maya during this same period Scholars have identified no grammatical or phonetic elements in the notational system and thus not know what languages its inhabitants spoke or what they called themselves Some scholars have proposed that its rulers sought to create a secretive, mysterious symbolism; others suggest that the signs’ meanings were probably clear to their creators and those who viewed them The artistic style at Teotihuacán is repetitive, uniform, and 455 somewhat stiff, in sharp contrast to the great variability of styles and motifs among the Maya city-states Religion was practiced in at least two distinct spheres: at the level of the household and village and at the level of the state Village- and household-level religious practices focused on ancestors and deities linked to specific lineages There is no evidence that these household- and village-level religious practices were in conflict with the state or that there was any organized or lower-class resistance to the state or ruling groups State religion was very distinct from village-level religion, emphasizing especially the cult of the Feathered Serpent, most graphically expressed in the Temple of Quetzalcoatl, with its hundreds of huge sculpted heads gracing its massive walls and stairs Other major state deities included what is commonly called Tlaloc, the rain god (though interpretations differ on whether this was indeed Tlaloc), the storm/war god, various death and underworld gods, and what E Pasztory has termed the Great Goddess State religion focused on legitimizing the dominance of ruling groups and providing ideological underpinning for the state and its political, military, and ideological dominion within the Basin of Mexico and beyond Located northeast of Mexico City in the Basin of Mexico are the massive ruins of the great city of Teotihuacán Despite extensive archaeological investigation, many mysteries remain about the people who built, ruled, and lived in this vast urban complex
