Huei tlamahuiçoltica
Huei Tlamahuiçoltica ("The Great Event") is a tract in Nahuatl comprising 36 pages and was published in Mexico City, Mexico in 1649 by Luis Laso de la Vega, the vicar of the chapel of Our Lady of Guadalupe at Tepeyac outside the same city. In the preface Luis Laso de la Vega claimed authorship of the whole work, but this claim is the subject of an ongoing difference of scholarly opinion.
