 The temple is dedicated to Huitzilopochtli and Tlaloc, the Aztec rain deity.Scholars believe that Mexica artists and builders incorporated images of the Coatepec narrative into the Huēyi Teōcalli during a major renovation from the years 4 Reed to 8 Reed (1483-1487) under the rule of Ahuitzotl.Eduardo Matos Moctezuma first noted that the placement of the monument at the bottom of the Templo Mayor commemorated the history of Huitzilopochtli defeating Coyolxauhqui in the battle on Mount Coatepetel.
