In our times, during the rule of Alexander VI, Oliverotto da Fermo, having been left an orphan many years before, was brought up by his maternal uncle, Giovanni Fogliani, and in the early days of his youth sent to fight under Paolo Vitelli, that, being trained under his discipline, he might attain some high position in the military profession.
After Paolo died, he fought under his brother Vitellozzo, and in a very short time, being endowed with wit and a vigorous body and mind, he became the first man in his profession. But it appearing to him a paltry thing to serve under others, he resolved, with the aid of some citizens of Fermo, to whom the slavery of their country was dearer than its liberty, and with the help of the Vitelli, to seize Fermo.
So he wrote to Giovanni Fogliani that, having been away from home for many years, he wished to visit him and his city, and in some measure to look into his patrimony; and although he had not laboured to acquire anything except honour, yet, in order that the citizens should see he had not spent his time in vain, he desired to come honourably, so would be accompanied by one hundred horsemen, his friends and retainers; and he entreated Giovanni to arrange that he should be received honourably by the citizens of Fermo, all of which would be not only to his honour, but also to that of Giovanni himself, who had brought him up.
Giovanni, therefore, did not fail in any attentions due to his nephew, and he caused him to be honourably received by the Fermans, and he lodged him in his own house, where, having passed some days, and having arranged what was necessary for his wicked designs, Oliverotto gave a solemn banquet to which he invited Giovanni Fogliani and the chiefs of Fermo.
When the viands and all the other entertainments that are usual in such banquets were finished, Oliverotto artfully began certain grave discourses, speaking of the greatness of Pope Alexander and his son Cesare, and of their enterprises, to which discourse Giovanni and others answered; but he rose at once, saying that such matters ought to be discussed in a more private place, and he betook himself to a chamber, whither Giovanni and the rest of the citizens went in after him.
No sooner were they seated than soldiers issued from secret places and slaughtered Giovanni and the rest. After these murders Oliverotto, mounted on horseback, rode up and down the town and besieged the chief magistrate in the palace, so that in fear the people were forced to obey him, and to form a government, of which he made himself the prince.
He killed all the malcontents who were able to injure him, and strengthened himself with new civil and military ordinances, in such a way that, in the year during which he held the principality, not only was he secure in the city of Fermo, but he had become formidable to all his neighbours.
And his destruction would have been as difficult as that of Agathocles if he had not allowed himself to be overreached by Cesare Borgia, who took him with the Orsini and Vitelli at Sinigaglia, as was stated above.
Thus one year after he had committed this parricide, he was strangled, together with Vitellozzo, whom he had made his leader in valour and wickedness.
