This epistle to Lorenzo's son, the brother of Cardinal Giovanni, shows that the greatest confidence existed between him and Caesar, who says in it that, on account of his sudden departure from Pisa, he had been unable to communicate orally with him, and that his preceptor, Juan Vera, would have to represent him.

He recommended his trusted familiar, Francesco Romolini, to Piero for appointment as professor of canon law in Pisa.
The letter is signed, "Your brother, Cesar de Borja, Elector of Valencia."[19] By not allowing his son to come to Rome immediately, Alexander wished to give public proof of what he had declared at the time of his election; namely, that he would hold himself above all nepotism.

Perhaps there was a moment when the warning afforded by the examples of Calixtus, Sixtus, and Innocent caused him to hesitate, and to resolve to moderate his love for his offspring.

However, the nomination of his son to a bishopric on the day of his coronation shows that his resolution was not very earnest.

In October Caesar appeared in the Vatican, where the Borgias now occupied the place which the pitiable Cibos had left.
On September 1st the Pope made the elder Giovanni Borgia, who was Bishop of Monreale, a cardinal; he was the son of Alexander's sister Giovanna.
The Vatican was filled with Spaniards, kinsmen, or friends of the now all-powerful house, who had eagerly hurried thither in quest of fortune and honors.
