A letter from Antonio Giustiniani, Venetian ambassador to the Pope, mentions an unnamed 'despot' in command of a cavalry unit in October 1502. Jonathan Harris believes that this might be a reference to Constantine Arianiti rather than Fernando. One of Andreas's successors as claimant to the position of despot, the name of whom is not mentioned in the sources, raised problems of protocol when he in 1518 invited
Pope Leo X to become the
godparent of his son Giovanni Martino Leonardo (
Joannes Martinus Leonhardus as written in Latin) and invited ten cardinals to the baptism. According to the contemporary Papal
master of ceremonies,
Paris de Grassis, the honors asked for was as if the despot believed himself to be "baptizing the Emperor of Christendom himself". Kenneth Setton believed that this despot was Constantine Arianiti, a sentiment also held by
Christian Gottfried Hoffmann, who included Paris de Grassis's account of the affair in his work
Nova scriptorum ac monumentorum partim rarissimorum partim ineditorum, a collection of historical texts, in 1731. Identification with Constantine is problematic since contemporary sources otherwise hold that Constantine only had a single son, named
Arianitto. Jonathan Harris believes that the 1518 despot could instead be Fernando. The territory claimed by the 1518 despot is not specified in de Grassis's material. There was another claimant despot active in Italy at the time,
Carlo III Tocco, claimant
despot of Epirus, who is attested to have had a son named
Giovanni Leonardo, born at some point in the 1510s. == Notes ==
