 All of these suggestions appear to be highly conjectural.Imperial seems to have been a poet of some note.He is one of the best represented poets in the "Cancionero de Baena", and in his "Proemio e carta al condestable don Pedro de Portugal", the Marques de Santillana singles out Imperial (and only Imperial, among writers in Spanish) as being worthy of the title of “poeta.” In addition, some of Imperial's poems were well known enough to have elicited poetic responses ("respuestas") from his contemporaries.
