These were the kingdom of Naples, the duchy of Milan, the magnificent republic of Florence, and the most serene republic of Venice.
The kingdom of Naples was in the hands of the old Ferdinand, whose birth was not only illegitimate, but probably also well within the prohibited degrees. His father, Alfonso of Aragon, received his crown from Giovanna of Naples, who had adopted him as her successor. But since, in the fear of having no heir, the queen on her deathbed had named two instead of one, Alfonso had to sustain his rights against Rene. The two aspirants for some time disputed the crown. At last the house of Aragon carried the day over the house of Anjou, and in the course of the year 1442, Alfonso definitely secured his seat on the throne. Of this sort were the claims of the defeated rival which we shall see Charles viii maintaining later on. Ferdinand had neither the courage nor the genius of his father, and yet he triumphed over his enemies, one after another he had two rivals, both far superior in merit to him self. The one was his nephew, the Count of Viana, who, basing his claim on his uncle’s shameful birth, commanded the whole Aragonese party; the other was Duke John of Calabria, who commanded the whole Angevin party. Still he managed to hold the two apart, and to keep himself on the throne by dint of his prudence, which often verged upon duplicity. He had a cultivated mind, and had studied the sciences—above all, law. He was of middle height, with a large handsome head, his brow open and admirably framed in beautiful white hair, which fell nearly down to his shoulders. Moreover, though he had rarely exercised his physical strength in arms, this strength was so great that one day, when he happened to be on the square of the Mercato Nuovo at Naples, he seized by the horns a bull that had escaped and stopped him short, in spite of all the efforts the animal made to escape from his hands. Now the election of Alexander had caused him great uneasiness, and in spite of his usual prudence he had not been able to restrain himself from saying before the bearer of the news that not only did he fail to rejoice in this election, but also that he did not think that any Christian could rejoice in it, seeing that Borgia, having always been a bad man, would certainly make a bad pope. To this he added that, even were the choice an excellent one and such as would please everybody else, it would be none the less fatal to the house of Aragon, although Roderigo was born her subject and owed to her the origin and progress of his fortunes; for wherever reasons of state come in, the ties of blood and parentage are soon forgotten, and, ‘a fortiori’, relations arising from the obligations of nationality.
Thus, one may see that Ferdinand judged Alexander VI with his usual perspicacity; this, however, did not hinder him, as we shall soon perceive, from being the first to contract an alliance with him.
