A Pyramid of Skulls
The principal fane of Huitzilopochtli was surrounded by upwards of forty inferior teocallis and shrines. In the Tzompantli (Pyramid of Skulls) were collected the grisly relics of the countless victims to the implacable war-god of the Aztecs, and in this horrid structure the Spanish conquerors counted no less than 136,000 human skulls. In the court or teopan which surrounded the temple were the dwellings of thousands of priests, whose duties included the scrupulous care of the temple precincts, and whose labours were minutely apportioned.
