Don Giovanni Cerviglione, a gentleman by birth and a brave soldier, captain of the pope's men-at-arms, was attacked one evening by the sbirri, as he was on his way home from supping with Dan Elisio Pignatelli.

One of the men asked his name, and as he pronounced it, seeing that there was no mistake, plunged a dagger into his breast, while a second man with a back stroke of his sword cut off his head, which lay actually at his feet before his body had time to fall.
The governor of Rome lodged a complaint against this assassination with the pope; but quickly perceiving, by the way his intimation was received, that he would have done better to say nothing, he stopped the inquiries he had started, so that neither of the murderers was ever arrested.

But the rumour was circulated that Caesar, in the short stay he had made at Rome, had had a rendezvous with Cerviglione's wife, who was a Borgia by birth, and that her husband when he heard of this infringement of conjugal duty had been angry enough to threaten her and her lover, too: the threat had reached Caesar's ears, who, making a long arm of Michelotto, had, himself at Forli, struck down Cerviglione in the streets of Rome.
Another unexpected death followed so quickly on that of Don Giovanni Cerviglione that it could not but be attributed to the same originator, if not to the same cause.

Monsignore Agnelli of Mantua, archbishop of Cosenza, clerk of the chamber and vice-legate of Viterbo, having fallen into disgrace with His Holiness, how it is not known, was poisoned at his own table, at which he had passed a good part of the night in cheerful conversation with three or four guests, the poison gliding meanwhile through his veins; then going to bed in perfect health, he was found dead in the morning.

His possessions were at once divided into three portions: the land and houses were given to the Duke of Valentinois; the bishopric went to Francesco Borgia, son of Calixtus III; and the office of clerk of the chamber was sold for 5000 ducats to Ventura Bonnassai, a merchant of Siena, who produced this sum for Alexander, and settled down the very same day in the Vatican.
This last death served the purpose of determining a point of law hitherto uncertain: as Monsignore Agnelli's natural heirs had made some difficulty about being disinherited, Alexander issued a brief; whereby he took from every cardinal and every priest the right of making a will, and declared that all their property should henceforth devolve upon him.
But Caesar was stopped short in the midst of his victories.
