In 1475 Madonna Giovanna de’ Catanei bore, to Cardinal Rodrigo, Don Juan Francisco de Borja, to whom (after the death in 1481 of Don Pedro Luis de Borja) his father ever gave the honours and the affection which are due to an eldest son and heir. This is the most important circumstantial evidence against Don Cesare’s right to the name of Borgia. In January of the same year, Cardinal Rodrigo was deputed, with a nephew of the Lord Xystus P.P. IV, one Cardinal Giuliano della Rovere, who, as a lad, had peddled onions in a boat between Arbisola and Genoa, to welcome King Don Ferrando I of Naples at Tarracina, on the occasion of his state-visit to the Holy See. Three days later, Cardinal Rodrigo said mass for his Majesty at San Paolo _extra muros_ when the king was leaving for Colonna’s fief at Marino, where English envoys from King Edward IV Plantagenet, who had just conferred the Most Noble Order of the Garter upon Duke Francesco Sforza-Visconti of Milan, were waiting with a similar attention for the King of Naples. On the tenth of June 1476 the plague appeared in Rome, and the Lord Xystus P.P. IV, attended by Cardinal Rodrigo, removed His court to Viterbo, where cooler air lessened the danger of contagion. In 1478 was the hideous Conspiracy of the Pazzi at Florence, which created no small stir in all Italy. Also in this year Madonna Giovanna de’ Catanei bore, to Cardinal Rodrigo, Madonna Lucrezia Borgia. On the first of October 1480, “Xystus, Bishop, Servant of the servants of God, to His beloved son Cesare (de Borja), a scholar of the age of six years,” sent “greeting and the Apostolic Benediction,” and dispensed him from the necessity of proving the legitimacy of his birth; a rule which must be observed (in the absence of a dispensation) by whoever shall wish to become eligible for ecclesiastical benefices. In 1481 died Don Pedro Luis de Borja, the eldest bastard of the Vicechancellor-Cardinal Rodrigo. He was of the age of twenty-one years, and betrothed to a mere child, the Princess Doña Maria de Aragona. Also, in 1481, Madonna Giovanna de’ Catanei bore, to Cardinal Rodrigo, Don Gioffredo Borgia.
