On June 12 Riario set out on his journey to Siena. A Sienese chronicler relates that the cardinal reached the city June 13th, and alighted at the house of Messer Tommé, bishop of Pienza, more dead than alive from the terror he had undergone, which was still so bewildering in its effect that he thought he felt the rope round his neck.[243] The scene of which he had been an involuntary spectator, and the danger which he had incurred of being seized by the furious crowd, had made the deepest impression on him. If it is true, as some say, that he never recovered his natural spirits, his whole later life proves at least that his frivolous disposition suffered no change; for forty years he lived in a turmoil of gaiety, splendour, and luxury, occupied with the execution of works of art, and sharing in amusements and intrigues which, towards the end of his worldly career, involved him in a far worse complication than did the conspiracy of the Pazzi. Four days before Riario’s liberation on June 1st, Sixtus IV. had published the bull of excommunication against Lorenzo de’ Medici who, according, to the usual style of such documents, was termed ‘iniquitatis filius et perditionis alumnus.’ His adherents and the members of the government were included. The bull begins with the enumeration of the old differences existing between the Pope and Florence, the protection afforded to Niccolò Vitelli, Carlo Fortebraccio, Deifebo dell’Anguillara, the attacks on the Papal territory in the valley of the Tiber, the hindrance to those journeying to Rome, whether they came to the city by land or by water, and the refusal to allow Francesco Salviati to take possession of his archiepiscopal chair. It then passed on to mention recent events, the murder of the archbishop and other priests, and the imprisonment of the cardinal on account of civil and family feuds, which had arisen because the Medici and their party had seized all power for themselves and had exercised it to the prejudice of others with severity and despotism. On these grounds the ban of the church was pronounced against Lorenzo, the priors, the Gonfaloniere, and other magistrates, and everyone who should afford them assistance, or had done so, as against traitors and desecrators of the Church. They were declared to be deprived of all possessions, all honours and offices, and the capability of bequeathing to their heirs. All their male descendants were included in this sentence. If Florence did not deliver up Lorenzo and his fellow culprits within a month, she should be deprived of her archbishopric, and with her entire territory, and those of Fiesole and Pistoja, be placed under an interdict.[244] It is a singular fact that, even after the publication of the bull, Cardinal d’Estouteville wrote to Lorenzo to acquaint him with the Papal grants of tithes in the territory of the Republic.[245] Thus war was declared. On both sides it was necessary to collect forces and gain allies.
