Topiltzin Ce Acatl Quetzalcoatl

Nahua tradition, recorded in colonial-era sources including the Codex Chimalpopoca and Sahagun's informants, remembered Topiltzin as the ruler of Tula who took the name and priestly devotion of the god Quetzalcoatl so completely that later memory frequently blurs king and deity together. He was credited with a restrained style of religious practice, favoring the sacrifice of snakes, birds and butterflies over human victims, and with fostering the Toltecs' reputation as accomplished builders, artisans and scholars, a golden age Aztec tradition looked back on as a model of civilized order.

That order was said to end through the sorcery of priests loyal to the rival god Tezcatlipoca, who in different tellings tricked Topiltzin into drunkenness with pulque, showed him his own aged and disfigured reflection in an obsidian mirror to shame him, or implicated him in a scandal with his own sister, breaking his authority and driving him from Tula in humiliation. He is said to have traveled east toward the coast, in some versions immolating himself and rising as the morning star, in others departing by raft across the sea, with an explicit promise to return.

Colonial-era Nahua and Spanish chroniclers, drawing on informants who had lived through the conquest, recorded that the Mexica ruler Moctezuma II and his court registered genuine unease at the 1519 arrival of Hernan Cortes, an anxiety the sources connect to the fact that Cortes landed in a year bearing the calendar name Ce Acatl, One Reed, the same year-sign associated with Topiltzin's prophesied return. Sahagun's Nahua informants describe this anxiety in some detail decades after the events they recount, and it has become one of the best known elements of the conquest narrative in popular retelling.

Modern historians treat the connection with real caution. Because the fullest surviving accounts of Mexica reaction to Cortes were recorded years after the conquest by informants working within a colonial Spanish framework already primed to read the encounter through a returning-god narrative, scholars debate how much of the "Quetzalcoatl returns" interpretation reflects genuine 1519 belief versus a story shaped, consciously or not, in hindsight to explain a catastrophic defeat. What is not in dispute is that the Topiltzin legend itself, and its prophesied return, was a genuine and important part of pre-conquest Nahua religious tradition regardless of how it was later invoked.
