 Matos Moctezuma has argued that the section of the Huēyi Teōcalli dedicated to Huitzilopochtli represents the sacred mountain of Coatepec where Huitzilopochtli was born and Coyolxauhqui died.The Coyolxauhqui stone was located in what was named Phase IV of the Templo Mayor during its excavation.The artist of the Coyolxauhqui stone carved this disk in high relief out of a single large stone, 3.25 meters in diameter.
