According to the legendary traditions of the Aztecs, the Mexica marked the end of the first Calendar Round of 52 years of wandering at a place called Coatepec, "Serpent Hill". As was the practice in Tenochtitlan, the ancestral Mexica carried out a New Fire ceremony to mark the end of one cycle of time and the beginning of another at this place. Because the 365-day solar calendar and the 260-day divination calendar take 52 years to reach their ends at the same moment, every day within a 52-year period had a unique date in the Aztec system. In some senses, then, restarting the calendars was re-initiating linear time, beginning history. The significance of the place where the Mexica accomplished this second beginning of time was linked by the Aztecs to the significance of mythological Coatepec, where their patron god Huitzilopochtli was born, by their shared name. In turn, the use of Coatepec as a figurative name for the Great Temple in Tenochtitlan placed the ceremonies held there in the same creative setting as both the birth of the god and the rebirth of the calendar.
