Conspiracy of Stefano Porcari against the papal government — The conspirators discovered and punished — The Florentines recover the places they had lost — Gherardo Gambacorti, lord of Val di Bagno, endeavors to transfer his territories to the king of Naples — Gallant conduct of Antonio Gualandi, who counteracts the design of Gambacorti — René of Anjou is called into Italy by the Florentines — René returns to France — The pope endeavors to restore peace — Peace proclaimed — Jacopo Piccinino attacks the Siennese.

The pontiff did not interfere in these affairs further than to endeavor to bring the parties to a mutual accommodation; but while he refrained from external wars he incurred the danger of more serious troubles at home. Stefano Porcari was a Roman citizen, equally distinguished for nobility of birth and extent of learning, but still more by the excellence of his character. Like all who are in pursuit of glory, he resolved either to perform or to attempt something worthy of memory, and thought he could not do better than deliver his country from the hands of the prelates, and restore the ancient form of government; hoping, in the event of success, to be considered a new founder or second father of the city. The dissolute manners of the priesthood, and the discontent of the Roman barons and people, encouraged him to look for a happy termination of his enterprise; but he derived his greatest confidence from those verses of Petrarch in the canzone which begins, “Spirto gentil che quelle membra reggi,” where he says,—

“Sopra il Monte Tarpejo canzon vedra,
Un cavalier, ch’ Italia tutta onora,
Pensoso piu d’altrui, che di se stesso.”

Stefano, believing poets are sometimes endowed with a divine and prophetic spirit, thought the event must take place which Petrarch in this canzone seemed to foretell, and that he was destined to effect the glorious task; considering himself in learning, eloquence, friends, and influence, superior to any other citizen of Rome. Having taken these impressions, he had not sufficient prudence to avoid discovering his design by his discourse, demeanor, and mode of living; so that the pope becoming acquainted with it, in order to prevent the commission of some rash act, banished him to Bologna and charged the governor of the city to compel his appearance before him once every day. Stefano was not daunted by this first check, but with even greater earnestness prosecuted his undertaking, and, by such means as were available, more cautiously corresponded with his friends, and often went and returned from Rome with such celerity as to be in time to present himself before the governor within the limit allowed for his appearance. Having acquired a sufficient number of partisans, he determined to make the attempt without further delay, and arranged with his friends at Rome to provide an evening banquet, to which all the conspirators were invited, with orders that each should bring with him his most trust-worthy friends, and himself promised to be with him before the entertainment was served. Everything was done according to this orders, and Stefano Porcari arrived at the place appointed. Supper being brought in, he entered the apartment dressed in cloth of gold, with rich ornaments about his neck, to give him a dignified appearance and commanding aspect. Having embraced the company, he delivered a long oration to dispose their minds to the glorious undertaking. He then arranged the measures to be adopted, ordering that one part of them should, on the following morning, take possession of the pontiff’s palace, and that the other should call the people of Rome to arms. The affair came to the knowledge of the pope the same night, some say by treachery among the conspirators, and others that he knew of Porcari’s presence at Rome. Be this as it may, on the night of the supper Stefano, and the greater part of his associates, were arrested, and afterward expiated their crime by death. Thus ended his enterprise; and though some may applaud his intentions, he must stand charged with deficiency of understanding; for such undertakings, though possessing some slight appearance of glory, are almost always attended with ruin.

Gherardo Gambacorti was lord of Val di Bagno, and his ancestors as well as himself had always been in the pay or under the protection of the Florentines. Alfonso endeavored to induce him to exchange his territory for another in the kingdom of Naples. This became known to the Signory, who, in order to ascertain his designs, sent an ambassador to Gambacorti, to remind him of the obligations of his ancestors and himself to their republic, and induce him to continue faithful to them. Gherardo affected the greatest astonishment, assured the ambassador with solemn oaths that no such treacherous thought had ever entered his mind, and that he would gladly go to Florence and pledge himself for the truth of his assertions; but being unable, from indisposition, he would send his son as an hostage. These assurances, and the proposal with which they were accompanied, induced the Florentines to think Gherardo had been slandered, and that his accuser must be alike weak and treacherous. Gherardo, however, hastened his negotiation with redoubled zeal, and having arranged the terms, Alfonso sent Frate Puccio, a knight of Jerusalem, with a strong body of men to the Val di Bagno, to take possession of the fortresses and towns, the people of which, being attached to the Florentine republic, submitted unwillingly.

Frate Puccio had already taken possession of nearly the whole territory, except the fortress of Corzano. Gambacorti was accompanied, while transferring his dominions, by a young Pisan of great courage and address, named Antonio Gualandi, who, considering the whole affair, the strength of the place, the well known bravery of the garrison, their evident reluctance to give it up, and the baseness of Gambacorti, at once resolved to make an effort to prevent the fulfillment of his design; and Gherardo being at the entrance, for the purpose of introducing the Aragonese, he pushed him out with both his hands, and commanded the guards to shut the gate upon such a scoundrel, and hold the fortress for the Florentine republic. When this circumstance became known in Bagno and the neighboring places, the inhabitants took up arms against the king’s forces, and, raising the Florentine standard, drove them out. The Florentines learning these events, imprisoned Gherardo’s son, and sent troops to Bagno for the defense of the territory, which having hitherto been governed by its own prince, now became a vicariate. The traitor Gherardo escaped with difficulty, leaving his wife, family, and all his property, in the hands of those whom he had endeavored to betray. This affair was considered by the Florentines of great importance; for had the king succeeded in securing the territory, he might have overrun the Val di Tavere and the Casentino at his pleasure, and would have caused so much annoyance, that they could no longer have allowed their whole force to act against the army of the Aragonese at Sienna.

In addition to the preparations made by the Florentines in Italy to resist the hostile League, they sent as ambassador, Agnolo Acciajuoli, ............
