The story which lies at the opening of the great feud between Guelph and Ghibelline in Florence throws a picturesque light on the temper of its nobility. Buondelmonte, the betrothed lover of a daughter of Oderigo Giantrufetti, passes beneath a palace of the Donati at whose window stands Madonna Aldruda with her two fair daughters. Seeing him pass by Aldruda calls aloud to him, pointing with her finger to the damsel by her side. "Whom have you taken to wife?" she says, "This is the wife I kept for you." The damsel pleased the youth, but his troth bound him, and he answered, "I can wed none other, now at any rate!" "Yes," cried Aldruda, "for I will pay the penalty for thee." "Then will I have her," said Buondelmonte. "Cosa fatta capo ha," was the famous comment of the outraged house--"stone dead has no fellow"--and as Dino puts it, in the most ordinary way in the world, "they settled to kill him the day he was to have married the damsel, and so they did." "Kill, kill," echoes everywhere through the story of these Florentine nobles. Assassination is an event of every day. Corso Donati sends murderers to kill an enemy among the Cerchi. Guido Cavalcanti strives to stab Corso in the back as he passes him. Where the dagger fails, they try poison without scruple. The best of them decline a share in a murder much as an Irish peasant may decline a share in an agrarian outrage, with a certain delicacy and readiness to stand by and see it done. When the assassination of the Bishop of Arezzo was decided on, Guglielmo da Pazzi, who was in the counsel, protested "he would have been content had it been done without his knowledge, but were the question put to him he might not be guilty of his blood." Among such men even Corso Donati towers into a certain grandeur:-- "Knight he was of great valour and renown, gentle of blood and manners, of a most fair body even to old age, comely in figure, with delicate features, and a white skin; a pleasing, prudent, and eloquent speaker; one who ever aimed at great ends; friend and comrade of great lords and nobles; a man too of many friends and great fame throughout all Italy. Foe he was of the people and its leaders; the darling of soldiers, full of evil devices, evil-hearted, cunning." Such was the man who drove Dante into exile:-- "Who for his pride was called 'Il Barone,' so that when he passed through the land many cried 'Viva Il Barone!' and the land seemed all his own."
