The Cult
Tlāloc's cult was anchored in the Templo Mayor of Tenochtitlan, where his blue-painted half of the double pyramid faced the great staircase; excavations under Eduardo Matos Moctezuma recovered offering caches of marine shells, coral, greenstone, and effigies of the rain god. His worship is far older than the Aztec: goggle-eyed storm gods appear in the murals of Teotihuacan and at Cholula, and mountain rain shrines throughout Mesoamerica were addressed to him. The Florentine Codex describes rituals at the summit of Mount Tlāloc, the petitioning of rain, and the dedication of children—quauhtli children especially—as messengers to the mountain's springs. Modern Nahua communities still conduct rain petitions, though Spanish Catholic frames have absorbed many of these rites.
