Besides the splendid sons of Guido and Ridolfo, there was yet another very wealthy and distinguished scion of the Baglione family, their young cousin Grifonetto. He was happily married to a young and beautiful wife, and was on friendly terms with all his cousins. His father, Grifone, had died young in battle; his still young and lovely mother, Atalanta Baglione, was extremely rich. She so greatly loved Grifonetto, her only child, that she remained a widow for his sake, and gave up her own home to live with him and his fair young wife, Zenobia Sforza, in the splendid palace he had built near Porta Marzia.
A few years before the end of the fifteenth century, the banished Oddi faction thought fit to attack the city; they rode suddenly in through the gates, and began to strike at the chains stretched across the street for defence against sudden attacks. The first to give the alarm was Simonetto Baglione, a young and beardless youth, who, though of a fierce and cruel nature, was heroically brave. He rushed forth in his shirt, armed only with sword and shield, and held the squadron of advancing Oddi at bay before the barrier that defended the Piazza. Soon ten of his adversaries lay dead at his feet. Till he had killed many more he persevered in attacking the foe with intense fury, until he had received twenty-two wounds. Then his cousin Astorre rode forth to help him. "Go and tend your wounds, Simonetto," he cried, and dashed at the common enemy; a falcon flashed on his gilded helmet, with the griffin's tail sweeping behind it. At once he became a target for the Oddi, their blows fell so thick and fast that each hindered the other from striking truly; nothing could be heard above the din of the strokes made by lances, partizans, crossbow quarries, and other weapons falling on Astorre's body; the sound of those great blows overbore the noise and shouting of the combatants. But the noble Astorre was undismayed by the horrid clamour, he rode his horse into the thickest of the fight, and trampled the Oddi under foot; while his horse, being a most fierce animal, gave the enemy what trouble it could, for so soon as they were jostled and overthrown by his rider, the beast trampled on them. By the time that the other Baglioni heroes sallied forth to help him, Astorre and his war-horse were overdone, they could scarce breathe.
The Oddi were again driven from the city, but a war followed which devastated the fertile country between Perugia and Assisi.
All through these fearful times of strife and bloodshed Art was progressing quietly and surely in Perugia. Raffaelle was at this time working in the atelier of Perugino, and it is thought that he must have witnessed this splendid defence of Astorre Baglione, and that he afterwards reproduced the young warrior, his helmet crowned by a falcon and tail of griffin, in the St. George of the Louvre, and the trampling horseman in the Heliodorus Stanza of the Vatican.
After this achievement the Baglioni seem to have had a short time of family peace. This was soon interrupted. Grifonetto's wealth, the splendid palace in which he lived with his lovely mother and Zenobia Sforza, his beautiful wife, helped to make him, young though he was, the most powerful member of the family. He and his wife dearly loved each other, and the chronicler says, "No wonder, for they were as beautiful as angels." But for evil counsellors, and the restless ambition of the Baglioni, this state of affairs might have lasted. Three of the evil and disappointed relatives clung to Grifonetto like limpets; these were his uncle Filippo, his cousin Carlo Baciglia Baglione, and a scandalously dissolute scoundrel named Jeronimo della Penna or Arciprete. They took counsel together as to how the sons of Guido and Ridolfo Baglione could be easiest put out of the way, so that their wealth and power might be divided among the conspirators. Too poor and of too ill-repute to act alone, they saw that their patron Grifonetto had all they lacked, and they resolved to persuade him to head their conspiracy. At first they strove to win him by the offer of supreme power in Perugia; he could revolt, they said, against the Papal yoke, and become sovereign ruler in the city. Grifonetto was not ambitious; he had all he wanted,—their proposals did not tempt him.
Astorre was about to wed a Roman bride, Lavinia, the daughter of a Colonna father and an Orsini mother, and the malcontent Baglioni decided that this marriage, which was to happen at the end of July, would be a great opportunity for ridding themselves of their hated kindred, as it would assemble every member of the family in Perugia, except Marcantonio, who, being out of health, was taking baths at Naples.
The conspirators took fresh counsel together; the time fixed for the marriage was now close at hand, they must at once win over Grifonetto to their schemes. They therefore told him that Zenobia, the beautiful wife he so adored, was unfaithful to him, with his cousin Gianpaolo, one of the sons of Ridolfo Baglione.
Grifonetto was furious; in his mad jealousy he believed this story, and thirsted for vengeance: he consented to head the conspiracy, and to rid the city of the elder branch of his family by a wholesale murder.
Among the conspirators were Jeronimo della Staffa, three members of the Corgna family and others; only two of those who engaged in this bloodthirsty scheme were over thirty years old.
The Baglioni were chiefly lodged in houses on or near the Porta Marzia; Astorre and his bride, on the night of the murder, were lodged in the beautiful palace of Grifonetto, which was the wonder of Perugia, and always pointed out to strangers as a marvel of magnificence both inside and out. Among his other treasures, Grifonetto possessed a lion; Astorre and Gianpaolo, the sons of Guido and Ridolfo Baglione, each owned one of the royal beasts, and their fearful roaring at night struck terror to the hearts of belated Perugians on their way home.
