Tlaloc

The Shrine of Tlaloc, atop the Templo Mayor, was dedicated to the god of rain, water, and fertility. It shared this most important spot in the ceremonial precinct with the shrine of Huitzilopochtli, who was the god of war and the sun. It is assumed that these two deities represented these two dualities in Aztec culture. Tlaloc is portrayed as a being with a grimacing face and large fangs.

The shrine was probably decorated inside and out, and embellished with "goggle-eyes" of Tlaloc painted in black upon white. The pillars were painted with images of human figures, at least in what remains of the stage II excavation. The sanctuary was probably adorned with shells, which stand for water.
