If Guidobaldo did engage in such an act, amounting to a betrayal, he was certainly paid by Cesare in kind and with interest. If the duke had been short of a pretext for carrying a drawn sword into the dominions of Guidobaldo, he had that pretext now in this act of enmity against himself and the Holy See.

First, however, he disposed for the attack upon Camerino. This State, lying on the Eastern spurs of the Apennines, midway between Spoleto and Urbino, was ruled by Giulio Cesare Varano, an old war-dog of seventy years of age, ruthless and bloodthirsty, who owed his throne to his murder of his own brother.

He was aided in the government of his tyranny by his four sons, Venanzio, Annibale, Pietro, and Gianmaria.

Several times already had he been menaced by Cesare Borgia, for he was one of the Vicars proscribed for the non-payment of tribute due to the Holy See, and at last his hour was come. Against him Cesare now dispatched an army under the command of Francesco Orsini, Duke of Gravina, and Oliverotto Eufreducci, another murderous, bloody gentleman who had hitherto served the duke in Vitelli’s condotta, and who, by an atrocious act of infamy and brigandage, had made himself Lord of Fermo, which he pretended—being as sly as he was bloody—to hold as Vicar for the Holy See.

This Oliverotto Eufreducci—hereafter known as Oliverotto da Fermo—was a nephew of Giovanni Fogliano, Lord of Fermo. He had returned home to his uncle’s Court in the early part of that year, and was there received with great honour and affection by Fogliano and his other relatives. To celebrate his home-coming, Oliverotto invited his uncle and the principal citizens of Fermo to a banquet, and at table contrived to turn the conversation upon the Pope and the Duke of Valentinois; whereupon, saying that these were matters to be discussed more in private, he rose from table and begged them to withdraw with him into another room.

All unsuspecting—what should old Fogliano suspect from one so loved and so deeply in his debt?—they followed him to the chamber where he had secretly posted a body of his men-at-arms. There, no sooner had the door closed upon this uncle, and those others who had shown him so much affection, than he gave the signal for the slaughter that had been concerted. His soldiers fell upon those poor, surprised victims of his greed, and made a speedy and bloody end of all.

That first and chief step being taken, Oliverotto flung himself on his horse, and, gathering his men-at-arms about him, rode through Fermo on the business of butchering what other relatives and friends of Fogliano might remain. Among these were Raffaele della Rovere and two of his children, one of whom was inhumanly slaughtered in its mother’s lap.

Thereafter he confiscated to his own uses the property of those whom he had murdered, and of those who, more fortunate, had fled his butcher’s hands. He dismissed the existing Council and replaced it by a government of his own. Which done—to shelter himself from the consequences—he sent word to the Pope that he held Fermo as Vicar of the Church.

Whilst a portion of his army marched on Camerino, Cesare, armed with his pretext for the overthrow of Guidobaldo, set himself deliberately and by an elaborate stratagem to the capture of Urbino. Of this there can be little doubt. The cunning of the scheme is of an unsavoury sort, when considered by the notions that obtain to-day, for the stratagem was no better than an act of base treachery. Yet, lest even in this you should be in danger of judging Cesare Borgia by standards which cannot apply to his age, you will do well to consider that there is no lack of evidence that the fifteenth century applauded the business as a clever coup.

Guidobaldo da Montefeltre was a good prince. None in all Italy was more beloved by his people, towards whom he bore himself with a kindly, paternal bonhomie. He was a cultured, scholarly man, a patron of the arts, happiest in the splendid library of the Palace of Urbino. It happened, unfortunately, that he had no heir, which laid his dominions open to the danger of division amongst the neighbouring greedy tyrants after his death. To avoid this he had adopted Francesco Maria della Rovere, hereditary Prefect of Sinigaglia, his sister’s child and a nephew of Cardinal Giuliano della Rovere’s. There was wisdom and foresight in the adoption, considering the favour enjoyed in Rome and in France by the powerful cardinal.
