The question of Valeriano's authorship of the
Nahuatl text known as
Nican Mopohua has become a point of contention in the long-running dispute over the historicity of the apparitions of the Virgin Mary (under the title
Our Lady of Guadalupe) to
Juan Diego in 1531. The
Nican Mopohua was published in 1649 by
Luis Laso de la Vega as part of a composite text known from its opening words as the
Huei tlamahuiçoltica, and de la Vega's claims of authorship in the preface to that work notwithstanding, the
Nican Mopohua has long been attributed to Valeriano. This attribution is based on a tradition dating back to the
Informaciones Jurídicas de 1666 and the assertions of Luis Becerra Tanco and, subsequently, Don
Carlos de Sigüenza y Góngora as to Valeriano's authorship and as to their acquaintance with the relative manuscripts in his hand-writing. Suggestions have been made that its content is incompatible with someone (such as Valeriano) who had close bonds with the Franciscans, and others have suggested that the
Huei tlamahuiçoltica is a unitary work which – despite the considerable objections against such a possibility – de la Vega wrote, with the assistance of a collaborator. Nevertheless, the general consensus among Mexican scholars (ecclesiastical and secular) remains that Valeriano is indeed the author of the
Nican Mopohua. ==See also==
