Life In The City Of The Gods

Inside the neighborhoods of Teotihuacan, Mesoamerica’s first great metropolis

When Popocatepetl, a volcano overlooking the southern Valley of Mexico, erupted in the first-century a.d., it blanketed nearby cities and farmlands with thick layers of ash. The cataclysm forced people to abandon their homes in search of arable land. Many of those fleeing the consequences of the eruption eventually made their way to the Teotihuacan Valley, 70 miles north of the volcano, where there were only a few scattered farming villages. Here, over roughly a century following the eruption, these refugees and their descendants laid out an urban grid, dug an extensive irrigation network, and built the center of what would become, for a time, the largest city in Mesoamerica, known today as Teotihuacan. The most politically and economically powerful center in the ancient Americas until the Aztecs forged their empire hundreds of years later, Teotihuacan owed its existence to the disaster of Popocatepetl’s eruption. “The city itself didn’t exist before the movement of fleeing people,” says Linda Manzanilla, an archaeologist at the National Autonomous University of Mexico who has been excavating in Teotihuacan for four decades. She and her colleagues estimate that at its peak around a.d. 400, some 100,000 people called the city home.
