It had been arranged that as soon as the proposed victims were asleep the signal should be given; this was to be a stone thrown from the loggia of the Magnifico Guido's palace, into the court below.
Banquets, jousts, all kinds of magnificent festivities had gone on for days past. That night a great supper was given, at which the conspirators were present; they appeared to be on the most friendly terms with the others, and were even affectionate and caressing to all,—yet the traitors had decided who was to be the murderer of each victim, and the number of bravi by which each murderer should be accompanied in case of resistance.
At last the time arrived. The victims, heavy with wine, had retired to rest, they slept undisturbed by the roaring of the lions. Then the signal was given; each assassin stood ready at the appointed door. Carlo Baglione, who seems to have been the mainspring of "el gran tradimento," as the chronicler Matarazzo calls it, made first for the sleeping-chamber of the head of the family, the "Magnifico Guido," but he turned aside to that of young Simonetto. Jeronimo della Penna forced open the door of the noble Gismondo; while Grifonetto himself attacked Gianpaolo, Filippo di Braccio and one of the Corgna family unlocked the door of valiant Astorre, who, asleep with his newly-married wife, was thus murderously awakened; the young fellow opened the door, and, seeing his murderers, he guessed the truth. As they attacked him he cried out, "Wretched Astorre, who dies like a coward." His young wife rushed up to him, and flung her arms round him, trying to make her body a shield between him and his assailants, but they had already stabbed him with many more blows than would have sufficed to kill him, and she too received a wound. Then the brutal Filippo di Braccio, seeing how large a wound was in Astorre's breast, thrust in his hand, tore out his heart, and savagely bit it. After this he and his accomplice flung the body of Astorre down the stairs and into the street, where presently the murdered Simonetto lay beside it. He had wakened, and, seeing the murderers kill the companion who lay in his chamber, armed himself, and fought his way through the villainous crowd of bravi, till he reached the foot of the stairs; here fresh assailants despatched him. Simonetto's uncle Guido had also time to snatch up his sword; but, powerful though he was, he was killed.
Grifonetto was less successful than his fellow-conspirators. Gianpaolo, the most daring of the elder branch of the Baglioni, had taken alarm, and so had his squire. But Gianpaolo was sagacious as well as brave, and, not knowing who were his assailants, he bade his squire guard the staircase which led from his chamber to the roof, while he tried to escape over the tops of the other palaces.
The squire fought valiantly, and held his post for some time,—the staircase turned, and gave him a point of vantage over his assailants from below. Gianpaolo reached the roof, and crawled over it till, coming to the skylight of his cousin Grifonetto's palace, he had a mind, in his ignorance as to the conspirators, to seek shelter there; but he gave up the idea, and climbed through a window into another house, owned by one of the citizens; the good man within was so terrified at the sight of Baglione, that, in his fear, he refused to harbour the great noble. Gianpaolo, going back to the roof, found his way into the atelier of some foreign artists, who were also greatly alarmed at his appearance among them. One of them, however, named Achille de la Mandola, seems to have greatly helped the fugitive.
Gianpaolo finally made his way out into the street; and soon after out of the city. Seeing a mule grazing by the wayside, he at once mounted it, though he was greatly disturbed to quit Perugia without having either discovered the meaning of this night attack, or taken vengeance on the unknown assassins. In the meantime day had broken, and Gentile Baglione, who lived some way from his father's house, had been also attacked by the conspirators; he escaped them at once, by mounting his horse and riding away. Just as he reached the bridge beyond the plain, he was amazed to recognise his elder cousin Gianpaolo, riding in the same direction on a mule.
When Atalanta, Grifonetto's beautiful young mother, heard of the tragedy that had been acted so close to her, she rose up, wrapped herself in a large cloak, and, taking with her the two little sons of Gianpaolo and her daughter-in-law, Zenobia Sforza, she quitted her son's house (she loved Grifonetto so dearly that she had always lived with him, having been widowed before she was twenty) and took refuge in her own dwelling on the Colle Landone. She had nothing with her but the cloak she wore, and when she learned in detail the events of the night she solemnly vowed she would never again cross her son's threshold. Grifonetto had quickly repented his crime. His eyes had opened to the wickedness into which his mad jealousy had betrayed him. As soon as he learned his mother's departure he followed her, but he was refused admittance; he, however, forced his way into her presence. She stayed his approach with outstretched hands, and delivered her solemn curse on his guilty head as the murderer of his nearest kindred. The young fellow fled horror-stricken from her presence, but soon returned; he could not find peace, he said, till his beloved, beautiful mother forgave him, and removed the curse she had laid on him.
Atalanta had, however, taken her precautions, and though the unhappy Grifonetto went again and again from his Palazzo to that on the Colle Landone, Atalanta refused to see or listen to him. With the exception of his complicity in this fearful tragedy, Grifonetto seems to have had more human feeling than some of his cousins of the elder branch. His suffering under his mother's curse, and his penitence for his crime, had completely unnerved him. When Gianpaolo, who by the death of his uncle Guido was now the head of the Baglioni, returned to Perugia with the troops he and his brothers had rallied round them, they were met at the city gate by an excited crowd of citizens; for though some of the Perugians still sided with their favourite Grifonetto, the larger portion abhorred his foul treason, and longed to see it avenged. Gianpaolo, seeing the concourse and hearing the cries of welcome, asked graciously that the ladies present in the crowd would be good enough to pray for his success. They did so, and sent out, besides, wine to refresh him and his soldiers after their journey, before they began to revenge themselves on their enemies. Grifonetto had come towards the gate with intent to guard it, gnashing his teeth and weeping, for he had made another attempt to see his mother. He presently met Gianpaolo on the Piazza, where some of the conspirators had already been slain,—Carlo Baglione and Jeronimo della Penna had a narrow escape by climbing the city wall.
Gianpaolo gazed with pitying contempt at his young cousin, who, still overwhelmed with remorse for his share in the unnatural crime, and heart-broken by his mother's curse, was taken aback at thus suddenly meeting his enemy within the city.
Gianpaolo rode up, and, pointing his sword at Grifonetto's throat, cried out; "Farewell, thou traitor Grifonetto; thou art"—Then he added, "Go, in God's name, for I will not kill you; I will not dip my hands in your blood, as you have dipped yours in the blood of your kindred."
