The moment in context
At the heart of Tenochtitlan stood a sacred precinct roughly 430–460 metres across. Bernardino de Sahagún’s informants listed 78 structures within it. The largest was the Templo Mayor, a pyramid with shrines to Huitzilopochtli, god of war and the sun, and Tlaloc, god of rain. Rulers enlarged it repeatedly: excavations led by Eduardo Matos Moctezuma since 1978 have identified seven major building stages. The city around this religious center was divided into four quarters, Moyotlan, Teopan, Atzacoalco and Cuepopan, with causeways leading north, west and south. Within the quarters were about seventy calpolli. These neighborhoods, each with temples, schools and officials, gave the capital manageable units of local government, much like boroughs.
