Diego de Moxena, el Liber sine nomine de Petrarca y el concilio de Constanza

On the 9th of July in 1415, Diego de Moxena, very likely a Castilian Franciscan active in the Council of Constance, wrote a letter to Ferdinand I of Aragon in which he urged him to attend the Council and to reconsider his support to Benedict XIII. Moxena’s missive reveals a particular use of the Liber sine nomine by Petrarch, already noticed by Isaac Vázquez Janeiro, but which calls forth closer attention. The document, being quite an early testimony in the history of Petrarch’s presence in Spain, makes use of the preface and the two first epistles of the Liber sine nomine not as a simple repertoire of maxims but as the very model on which the letter is written; besides, and most extraordinarily, the name of Petrarch is not even once mentioned throughout the text. Apart from that, this paper questions some of the sources put forward by Vázquez Janeiro and offers a new and revised edition of Fray Diego’s letter.
