It was necessary for their first plan that Lorenzo should be lured to Rome where the conspirators had assembled, but he refused an invitation to confer with the Pope about their differences and a new plan had to be substituted. Accordingly the nephew of Riario, Cardinal Raffaelle Sansoni, expressed a keen desire to view the treasures of the Medici household, and was welcomed as a guest by Florence. He attended mass in the Cathedral which was to be the scene of the assassination, since Lorenzo and his brother were certain to attend it. Two priests offered to perform the deed of sacrilege from which the original assassin recoiled. They hated Lorenzo for his treatment of Volterra, and drove him behind the gates of the new sacristy. Giuliano was slain at the very altar, his body being pierced with no less than nineteen wounds, but Lorenzo escaped to mourn the fate of the handsome noble brother who had been a model for Botticelli's famous "Primavera." He heard the citizens cry, "Down with traitors! The Medici! The Medici!" and resolved to move {39} them to a desperate vengeance on the Pazzi. The Archbishop of Pisa was hanged from the window of a palace, while a fellow-conspirator was hurled to the ground from the same building. This gruesome scene was painted to gratify the avengers of Giuliano. Florence was enthusiastic in defence of her remaining tyrant. He was depicted by Botticelli in an attitude of triumph over the triple forces of anarchy, warfare and sedition. All the family of Pazzi were condemned as traitors. Their coat of arms was erased by Lorenzo's adherents wherever it was discovered. Henceforth, Lorenzo exercised supreme control over his native city. He won Naples to a new alliance by a diplomatic visit that proved his skill in foreign negotiations. The gifts that came to him from strange lands were presented, in reality, to the master of the Florentine "republic." Egypt sent a lion and a giraffe, which were welcomed as wonders of the East even by those who did not appreciate the fact that they showed a desire to trade. It was easy soon to find new markets for the rich burghers whose class was in complete ascendancy over the ancient nobles. Lorenzo was seized with mortal sickness in the early spring of 1492, and found no comfort in philosophy. He drank from a golden cup which was supposed to revive the dying when it held a draught, strangely concocted from precious pearls according to some Eastern fancy. But the sick man found nothing of avail in his hour of death except a visit from an honest monk he had seen many times in the cloisters of San Marco.
