rain deity from the Aztecs, but blurred the line between sacrifice and captive capture, and religion. Tlaloc was also associated with the earth, and it is believed this is also a reason why sacrifices may have been made to him. Sacrifices to Tlaloc were not solely a Maya phenomenon, and it is known that the Aztecs also made sacrifices to Tlaloc. Just as the Maya had also worshipped their own version of Tlaloc, so did the Mixtec people of Oaxaca, who were known to worship a rain god that is extremely similar to other manifestations of Tlaloc. The commonalities between the different Mesoamerican cultures; interpretations of Tlaloc belies the common origin of Tlaloc as a rain god from Teotihuacán. Mythology In Aztec cosmology, the four corners of the universe are marked by "the four Tlalocs" () 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. On page 28 of the Codex Borgia, the Five Tlaloque are pictured watering maize fields. Each Tlaloc is pictured watering the maize with differing types of rains, of which only one was beneficial. The rain that was beneficial to the land was burnished with jade crystals and likely represented the type of rain that would make a bountiful harvest. The other forms of rain were depicted as destroyers of crops, “fiery rain, fungus rain, wind rain, and flint blade rain”. This depiction shows the power that Tlaloc had over the Central American crop supply. Also, the high ratio of damaging rains to beneficial rains likely symbolizes the ratio of the likelihood that crops are destroyed to them being nourished. This would explain why so much effort and resources were put forth by the Central Americans in order to appease the Gods. 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. In Aztec mythic cosmography, Tlaloc ruled the fourth layer of the upper world, or heavens, which is called Tlalocan ("place of Tlaloc") in several Aztec codices, such as the
