Dedication of the Aztec Great Temple (Templo Mayor)
In 1487, the eighth tlatoani of Tenochtitlan, Ahuitzotl, presided over the consecration of the sixth and final expansion of the Templo Mayor — the great double pyramid at the heart of the Aztec capital. The ceremony was one of the most consequential ritual events in pre-Columbian Mesoamerican history, both as an act of statecraft and as an extreme demonstration of the Aztec sacrificial complex. The Templo Mayor was not a single building but a structure rebuilt and enlarged repeatedly over two centuries, with each new tlatoani encasing the previous pyramid within a larger outer shell — much as Russian nesting dolls work, but on a monumental scale. By 1487 it stood approximately 60 metres high, with twin shrines at the summit: the red shrine of Huitzilopochtli (god of war and the sun) and the blue shrine of Tlaloc (god of rain and agriculture). The duality was structural: the empire required both war (to capture sacrificial victims who nourished the sun) and rain (to produce the agricultural surplus that supported the capital). Ancient Aztec and early Spanish sources describe the 1487 consecration ceremony as involving the sacrifice of between 4,000 and 80,400 war captives over four days — the vast range reflects both the difficulty of counting at scale and the likelihood of subsequent exaggeration for political effect. Modern historians consider the higher figures implausible (the logistics of killing 80,000 people in four days exceed what the archaeological record of the sacrificial precinct can support), but accept that thousands died. Captives had been accumulated from across the empire specifically for this event. The political logic of the ceremony was as important as its religious meaning. The presence of rulers and ambassadors from neighbouring states — including rivals and potential enemies — was carefully stage-managed. Witnesses to the slaughter were also witnesses to the empire's military capacity to accumulate tens of thousands of captives. The ceremony announced that the Aztec Triple Alliance was the dominant power of Mesoamerica and demonstrated the consequences of resisting it. The Templo Mayor's ruins were discovered beneath Mexico City in 1978 during excavations for an electricity cable; the archaeological zone now occupies a city block adjacent to the Metropolitan Cathedral.
