On the other hand, Juan Victorio postulates the author to be a native of Zamora (who very well may be related professionally with the diocese of Palencia) and educated, as shown by the author's diplomatic and heraldic knowledge. His theory is supported by the presence in the "Mocedades" of some Leonese linguistics, the knowledge of Zamorano microtoponymy shown by the author, the constant placing of the king's court in Zamoma in the poem, the encounter that Rodrigo has with King Ferdnando in Granja de Moreruela (Zamora), and imprecisions that deal with the local Palentine traditions that the cantar contains.
