One Title, Two Cults

Spanish colonial chroniclers working from Nahua informants, Sahagun and Duran chief among them, describe Tenochtitlan's religious hierarchy as topped not by a single supreme pontiff but by two priests holding the same title, Quetzalcoatl Tlamacazqui, each attached to one of the twin shrines atop the Templo Mayor. One served the cult of Huitzilopochtli, the Mexica patron god of war and the sun, and the other served the cult of Tlaloc, the much older rain and agricultural fertility god whose worship the Mexica had absorbed from earlier Valley of Mexico traditions. The shared title, invoking Quetzalcoatl even for offices dedicated to other gods, reflected a broader Nahua pattern in which Quetzalcoatl's name and priestly ideal carried associations of wisdom and legitimate religious authority transferable across cults.

The two office-holders were described by colonial sources as ranking equally, deliberately balancing the demands of Huitzilopochtli's martial cult against Tlaloc's agricultural one at the very top of the priestly hierarchy, a structural pairing that mirrored the physical layout of the Templo Mayor itself, whose single platform carried two separate summit shrines rather than one, and whose religious calendar interleaved festivals honoring war and rain across the year.
