Tlaloc

Tlaloc (Classical Nahuatl: Tlāloc [ˈtɬaːlok]) was part of the pantheon of gods in Aztec religion. As supreme god of the rain, Tlaloc was also by extension a god of earthly fertility and of water. He was widely worshipped as a beneficent giver of life and sustenance, but he was also feared for his ability to send hail, thunder, and lightning, and for being the lord of the powerful element of water. Tlaloc is also associated with caves, springs, and mountains, most specifically the sacred mountain in which he was believed to reside. His animal forms include herons and water-dwelling creatures such as amphibians, snails, and possibly sea creatures, particularly shellfish. The Mexican marigold, Tagetes lucida, known to the Aztecs as yauhtli, was another important symbol of the god, and was burned as a ritual incense in native religious ceremonies.

The cult of Tlaloc is one of the oldest and most universal in ancient Mexico. Although the name Tlaloc is specifically Aztec, worship of a storm god like Tlaloc, associated with mountaintop shrines and with life-giving rain, is as at least as old as Teotihuacan and likely was adopted from the Maya god Chaac or vice versa, and/or ultimately perhaps from an earlier Olmec precursor. An underground Tlaloc shrine has been found at Teotihuacan.

In Aztec cosmology, the four corners of the universe are marked by "the four Tlalocs" (Classical Nahuatl: Tlālōquê [tɬaːˈloːkeʔ]) which both hold up the sky and function as the frame for the passing of time. Tlaloc was the patron of the Calendar day Mazātl. In Aztec mythology, Tlaloc was the lord of the third sun which was destroyed by fire.

Additionally, Tlaloc is thought to be one of the patron deities of the trecena of 1 Quiahuitl (along with Chicomecoatl). Trecenas are the thirteen-day periods into which the 260-day calendar is divided. The first day of each trecena dictates the augury, or omen, and the patron deity or deities associated with the trecena.
