Cosimo.[32]

The letter of Lorenzo de’ Medici and those of Francesco Sforza to Cosimo relate to a second war with Lucca, and need some explanation. The recall of Cosimo from exile, as told in his diary, was followed by a wholesale banishment of his enemies from Florence, and left him practically master of the Republic. The exiled Florentines naturally desired to return, and according to the custom of the time were eager to invoke foreign aid. The times for long offered no opportunity. But in 1436 Genoa at last shook off the yoke of the Duke of Milan and became a republic. The sister republics of Florence and Venice at once allied themselves with the new free State, and Filippo Visconti believed himself to be seriously threatened by the new league. He had at the same time lost the services of one of his two great generals. Francesco Sforza, determined to acquire a principality for himself, had seized part of the Marches which nominally belonged to the Popes. In these circumstances the Duke of Milan resolved to attack Florence, the one of the allies which lay nearest to him. While the Florentines engaged mercenary troops (Taliano, or Tagliano, mentioned in the letters, being one of the leaders of small bands) and named Sforza the General of the Republic—a very untrustworthy general, as events proved. In the war which ensued Lucca was attacked by the Florentines and defended by the troops of Milan. In 1438 Florence was twice threatened by Visconti’s army, then in the territory of Lucca. The second time they were led by the famous condottiere Niccolò Piccinino, and Francesco Sforza had orders to oppose him and if possible to seize Lucca. The attempt failed, partly because Sforza, always hoping to obtain the hand of Madonna Bianca, Visconti’s illegitimate daughter, did not wish to offend him by fighting against his troops, partly because Venice, jealous of the possible acquisition of Lucca by Florence, laid claim to his services and refused to pay her share of his stipend unless her commands were obeyed. Cosimo went to Venice “thinking,” writes Machiavelli, “to be able to persuade her. To the Senate he pointed out the condition of Italy, the power of the Duke of Milan, his reputation and the number of his troops, and concluded by saying that if the Count (Sforza) went over to him they would together command the sea, and the liberty of Venice would be endangered. To this the Venetians replied that they well knew their own power and the power of the Italians, and believed they could defend themselves. Adding that they were not in the habit of recompensing soldiers for serving others, and that the Florentines, having made use of the Count, might pay him themselves. They considered it more necessary for the safety of their State to lower his pride than to give him money; and the ambition of men being unlimited, if he were paid now without serving them, he would eventually advance far more dishonest and dangerous demands. Thus it seemed to them desirable to curb his insolence before it became too great. But if out of fear, or for any other reason, the Florentines desired to retain his friendship, they were at liberty to pay him. Thus Cosimo returned without concluding anything.”[33]

Cosimo never forgave the Venetians for traversing his plans, and the enmity between the two Republics began from that day.

Niccolò Fortebraccio to Cosimo de’ Medici and Neri di Gino Capponi

Magnifico Domino et spectabili viro Fratibus carissimus Cosme de Medicis civitatis Flor. Vexillifero et Nero Gino de Capponibus.

Magnifice Domine ac spectabilis vir frates carissimi,—In order that you may be kept informed of what sometimes happens here I tell you that the messengers of your magnificent General Count Francesco [Sforza] had the courtesy to come rather to us than to those to whom they were sent. For your information I send you the enclosed copy of a letter from the aforesaid Count found in the bosom of one of his people, by which you will understand, &c. You will no doubt take counsel about it with your friends, so that I shall not have to call you blind Florentines,[34] as others have called you before. By my faith you ought not to be, but rather you should have a hundred eyes like Argus.—Assisi, January 5, 1436 (1437).

Lorenzo de’ Medici to his brother Cosimo de’ Medici, ambassador to Ferrara, in the name of the “Dieci di Balìa”

Spectabilis collega noster carissime,—Yesterday I wrote to thee by Messer Alexio. Since then we have nought from thee. Now we write because having turned over in our own minds this affair of Taliano and consulted with other citizens about it, it seems to us that it would be an excellent thing for the State of Count Francesco and for the League if some arrangement could be come to between His Holiness the Pope and the aforesaid Count as to the Marches, as thou art aware was once proposed. We therefore tell thee to employ every possible means to achieve this, which would be a most excellent thing, and as soon as thou canst learn aught about the intention of the Holy Father let us know, because until we hear from thee we shall not communicate with the Count.

To-day we have received a letter from our ambassadors to the Count, of which we enclose a copy. It appears to us a new departure, of which we know nothing, which we do not understand, nor can we judge how the Signoria of Venice will take it when they hear. Think over it well, and if it seems good to thee to tell them or to take any other steps, do so, only make them understand perfectly that we have nothing to do with this affair, which is quite outside our intentions, and above all declare that it is our desire to live in perfect brotherhood and friendship with that Signoria, and thus to cause the Count to keep on good terms with them. If this letter finds thee at Ferrara, and thou thinkest well to send or to write to Venice about this business, or if thou thinkest better neither to send or to write, do as it seemeth best to thee, for we place complete trust in thy well-known prudence. To-day Messer Giuliano Davanzati has been named ambassador to Venice by the Signori and the Colleges, and they have sent for him to Pisa.—Florence, January 29, 1437 (1438).
