Infessura states in his diaries that Roderigo desiring later—as Pope Alexander VI—to create cardinal his son by her, Cesare Borgia, he caused false witness to be borne to the fact that Cesare was the legitimate son of one Domenico d’Arignano, to whom he, the Pope, had in fact married her. Guicciardini(1) makes the same statement, without, however, mentioning name of this d’Arignano.

Now, bastards were by canon law excluded from the purple, and it is probably upon this circumstance that both Infessura and Guicciardini have built the assumption that some such means as these had been adopted to circumvent the law, and—as so often happens in chronicles concerning the Borgias—the assumption is straightway stated as a fact. But there were other ways of circumventing awkward commandments, and, unfortunately for the accuracy of these statements of Infessura and Guicciardini, another way was taken in this instance. As early as 1480, Pope Sixtus IV had granted Cesare Borgia—in a Bull dated October 1(1)—dispensation from proving the legitimacy of his birth. This entirely removed the necessity for any such subsequent measures as those which are suggested by these chroniclers.

of Burchard’s Diarium.

Moreover, had Cardinal Roderigo desired to fasten the paternity of Cesare on another, there was ready to his hand Vannozza’s actual husband, Giorgio della Croce.(2) When exactly this man became her husband is not to be ascertained. All that we know is that he was so in 1480, and that she was living with him in that year in a house in Piazza Pizzo di Merlo (now Piazza Sforza Cesarini) not far from the house on Banchi Vecchi which Cardinal Roderigo, as Vice-Chancellor, had converted into a palace for himself, and a palace so sumptuous as to excite the wonder of that magnificent age.

2 D’Arignano is as much a fiction as the rest of
Infessura’s story.

This Giorgio della Croce was a Milanese, under the protection of Cardinal Roderigo, who had obtained for him a post at the Vatican as apostolic secretary. According to some, he married him to Vannozza in order to afford her an official husband and thus cloak his own relations with her. It is an assumption which you will hesitate to accept. If we know our Cardinal Roderigo at all, he was never the man to pursue his pleasures in a hole-and-corner fashion, nor one to bethink him of a cloak for his amusements. Had he but done so, scandalmongers would have had less to fasten upon in their work of playing havoc with his reputation. What is far more likely is that della Croce owed Cardinal Roderigo’s protection and the appointment as apostolic secretary to his own complacency in the matter of his wife’s relations with the splendid prelate. However we look at it, the figure cut in this story by della Croce is not heroic.

Between the years 1474 and 1476, Vannozza bore Roderigo two sons, Cesare Borgia (afterwards Cardinal of Valencia and Duke of Valentinois), the central figure of our story, and Giovanni Borgia (afterwards Duke of Gandia).

Lucrezia Borgia, we know from documentary evidence before us, was born on April 19, 1479.

But there is a mystery about the precise respective ages of Vannozza’s two eldest sons, and we fear that at this time of day it has become impossible to establish beyond reasonable doubt which was the firstborn; and this in spite of the documents discovered by Gregorovius and his assertion that they remove all doubt and enable him definitely to assert that Giovanni was born in 1474 and Cesare in 1476.
