The actual assassins were Francesco de' Pazzi and Bernardo Bandini, who were nominally friends of the Medici (Francesco's brother Guglielmo having married Bianca de' Medici, Lorenzo's sister), and two priests named Maffeo da Volterra and Stefano da Bagnone. A professional bravo named Montesecco was to have killed Lorenzo, but refused on learning that the scene of the murder was to be a church. At that, he said, he drew the line: murder anywhere else he could perform cheerfully, but in a sacred building it was too much to ask. He therefore did nothing, but, subsequently confessing, made the guilt of all his associates doubly certain. When High Mass began it was found that Giuliano was not present, and Francesco de' Pazzi and Bandini were sent to persuade him to come--a Judas-like errand indeed. On the way back, it is said, one of them affectionately placed his arm round Giuliano--to see if he wore a shirt of mail--remarking, to cover the action, that he was getting fat. On his arrival, Giuliano took his place at the north side of the circular choir, near the door which leads to the Via de' Servi, while Lorenzo stood at the opposite side. At the given signal Bandini and Pazzi were to stab Giuliano and the two priests were to stab Lorenzo. The signal was the breaking of the Eucharistic wafer, and at this solemn moment Giuliano was instantly killed, with one stab in the heart and nineteen elsewhere, Francesco so overdoing his attack that he severely wounded himself too; but Lorenzo was in time to see the beginning of the assault, and, making a movement to escape, he prevented the priest from doing aught but inflict a gash in his neck, and, springing away, dashed behind the altar to the old sacristy, where certain of his friends who followed him banged the heavy bronze doors on the pursuing foe. Those in the cathedral, mean-while, were in a state of hysterical alarm; the youthful cardinal was hurried into the new sacristy; Guglielmo de' Pazzi bellowed forth his innocence in loud tones; and his murderous brother and Bandini got off.
