While Don Ludovico Maria Sforza-Visconti was suggesting an alliance between the Pope, the duchy of Milan, and the Republic of Venice, to overawe the Neapolitan Bond, King Don Ferrando was intriguing with a view to discover whether he could make a better bargain with the Sovereign Pontiff than with Colonna + Orsini + della Rovere. This was not treachery. It was merely the Neapolitan method, of which all Italy was fully cognizant. The King’s Majesty sent envoys to Rome, to Milan, and to Tuscany, to try to settle the Cervetri-Anguillara affair by pacific means. The Lord Alexander P.P. VI was well aware that no confidence could be placed in King Don Ferrando I: but by way of giving him a chance He proposed a marriage between His bastard, Don Gioffredo Borgia, now of the age of twelve years, and Madonna Lucrezia, a grand-daughter of the Majesty of Naples. At the same time He gathered troops and fortified the Vatican and the Mola of Hadrian, with the gallery-passage, called Lo Andare, which connects them, enabling Pope and cardinals to run, in time of danger, from the Apostolic Palace to the impregnable fortress tomb by Tiber. The Republic of Venice flung itself into the arms of Don Ludovico Maria Sforza-Visconti; for the Doge and Senate were dreadfully afraid lest the impassioned appeals of the Duchess Isabella on behalf of her husband, the pathetic Duke Giangaleazzo, should receive the attention of Naples. If the said Duke Giangaleazzo should come to owe his throne to King Don Ferrando I, then Milan would be, to all intents and purposes, a fief of the Regno; and to have Naples lording it in Northern Italy would by no means satisfy Venice, which, on this account, preferred alliance with the usurping Regent, even at the cost of winking at his usurpation of the Regency of Milan. Now Milan and Venice in alliance were a menace to their own neighbours; and, acting on the principle that made those two Powers one, the duchies of Mantua and Ferrara, and the Republic of Siena, hastened to fall into line with them. This concatenation, being superior to anything that Naples could exhibit, also caused the Lord Alexander P.P. VI to arrive at a decision: and, on the twenty-fifth of April 1493, accompanied by an armed cavalcade of Sforza and Cesarini for the ocular instruction of Colonna and Orsini, the Holiness of the Pope proceeded through Rome to the Venetian church of San Marco, on Piazza Venezia, where He ceremonially published the Bull of League between the Papacy, the duchies of Milan, Mantua, and Ferrara, and the Republics of Venice and Siena; after which, the river-port of Rome at Ostia being in His enemies’ hands, He began to fortify the land-port of Rome at Civita Vecchia, by way of giving effect to His warlike proclamation.
