But this was no real and adequate revenge; for it did not touch Charles himself, the sole author of all the troubles that the pope and his family had experienced during the last year. So Caesar soon abandoned vulgar schemes of this kind and busied himself with loftier concerns, bending all the force of his genius to restore the league of Italian princes that had been broken by the defection of Sforza, the exile of Piero dei Medici, and the defeat of Alfonso. The enterprise was more easily accomplished than the pope could have anticipated. The Venetians were very uneasy when Charles passed so near, and they trembled lest, when he was once master of Naples, he might conceive the idea of conquering the rest of Italy. Ludovico Sforza, on his side, was beginning to tremble, seeing the rapidity with which the King of France had dethroned the house of Aragon, lest he might not make much difference between his allies and his enemies. Maximilian, for his part, was only seeking an occasion to break the temporary peace which he had granted for the sake of the concession made to him. Lastly, Ferdinand and Isabella were allies of the dethroned house. And so it came about that all of them, for different reasons, felt a common fear, and were soon in agreement as to the necessity of driving out Charles viii, not only from Naples, but from Italy, and pledged themselves to work together to this end, by every means in their power, by negotiations, by trickery, or by actual force. The Florentines alone refused to take part in this general levy of arms, and remained faithful to their promises.
According to the articles of the treaty agreed upon by the confederates, the alliance was to last for five-and-twenty years, and had for ostensible object the upholding of the majority of the pope, and the interests of Christendom; and these preparations might well have been taken for such as would precede a crusade against the Turks, if Bajazet’s ambassador had not always been present at the deliberations, although the Christian princes could not have dared for very shame to admit the, sultan by name into their league. Now the confederates had to set on foot an army of 30,000 horse and 20,000 infantry, and each of them was taxed for a contingent; thus the pope was to furnish 4000 horse, Maximilian 6000, the King of Spain, the Duke of Milan, and the republic of Venice, 8000 each. Every confederate was, in addition to this, to levy and equip 4000 infantry in the six weeks following the signature of the treaty. The fleets were to be equipped by the Maritime States; but any expenses they should incur later on were to be defrayed by all in equal shares.
