This article aims to analyze traces of Aztec cultural memory recorded in sixteenth-century cultural sources of Central Mexico. It is a study of the particular case of an Aztec hero named Tlacahuepan, whose glorious death was commemorated in many songs and chronicles. The texts in question reveal highly symbolic language, as well as clearly established narrative patterns. The study of their discursive tools can cast considerable light on the ideological background that underlies the oral tradition on which these stories have been based. It can also contribute to a better understanding of the methods and strategies employed by the Aztecs to memorize the past and explain the present.
