Since, however, neither Alexander nor Caesar had changed in their perpetual dissimulation towards him, he was beginning to lose his fear, when he received an invitation from the pope and his son to take part in a bull-fight which was to be held in the Spanish fashion in honour of the duke before his departure: In the present precarious position of Naples it would not have been good policy far Alfonso to afford Alexander any sort of pretext for a rupture, so he could not refuse without a motive, and betook himself to Rome.

It was thought of no use to consult Lucrezia in this affair, for she had two or three times displayed an absurd attachment for her husband, and they left her undisturbed in her government of Spoleto.
Alfonso was received by the pope and the duke with every demonstration of sincere friendship, and rooms in the Vatican were assigned to him that he had inhabited before with Lucrezia, in that part of the building which is known as the Torre Nuova.
Great lists were prepared on the Piazza of St.Peter's; the streets about it were barricaded, and the windows of the surrounding houses served as boxes for the spectators.

The pope and his court took their places on the balconies of the Vatican.
The fete was started by professional toreadors: after they had exhibited their strength and skill, Alfonso and Caesar in their turn descended to the arena, and to offer a proof of their mutual kindness, settled that the bull which pursued Caesar should be killed by Alfonso, and the bull that pursued Alfonso by Caesar.
Then Caesar remained alone an horseback within the lists, Alfonso going out by an improvised door which was kept ajar, in order that he might go back on the instant if he judged that his presence was necessary.

At the same time, from the opposite side of the lists the bull was introduced, and was at the same moment pierced all over with darts and arrows, some of them containing explosives, which took fire, and irritated the bull to such a paint that he rolled about with pain, and then got up in a fury, and perceiving a man on horseback, rushed instantly upon him.

It was now, in this narrow arena, pursued by his swift enemy, that Caesar displayed all that skill which made him one of the finest horsemen of the period.
