Guidi, which was near the houses of the Pazzi and Donati, who were more ancient of blood but not so rich; therefore, seeing the Cerchi rise to great dignity, and that they had walled and enlarged the palace, and kept great state, the Donati began to have a great hatred against them." Villani gives the same account of the feud.[17] "It began in that quarter of scandal the Sesta of Porta S. Piero, between the Cerchi and Donati, on the one side through jealousy, on the other through churlish rudeness. Of the house of the Cerchi was head Messer Vieri de' Cerchi, and he and those of his house were people of great business, and powerful, and of great relationships, and most wealthy traders, so that their company was one of the greatest in the world; men they were of soft life, and who meant no harm; boorish and ill-mannered, like people who had come in a short time to great state and power. The Donati were gentlemen and warriors, and of no excessive wealth.... They were neighbours in Florence and in the country, and by the conversation of their jealousy with the peevish boorishness of the others, arose the proud scorn that there was between them." The glories of Campaldino were not as oil on these troubled waters. The conquerors flouted each other all the more fiercely in the streets on their return, and ill-treated the lower people with less scruple. No gathering for festive or serious purposes could be held without tempting strife. A marriage, a funeral, a ball, a gay procession of cavaliers and ladies—any meeting where one stood while another sat, where horse or man might jostle another, where pride might be nettled or temper shown, was in danger of ending in blood. The lesser quarrels meanwhile ranged themselves under the greater ones; and these, especially that between the Cerchi and Donati, took more and more a political character. The Cerchi inclined more and more to the trading classes and the lower people; they threw themselves on their popularity, and began to hold aloof from the meetings of the "Parte Guelfa," while this organised body became an instrument in the hands of their opponents, a club of the nobles. Corso Donati, besides mischief of a more substantial kind, turned his ridicule on their solemn dulness and awkward speech, and his friends the jesters, one Scampolino in particular, carried his gibes and nicknames all over Florence. The Cerchi received all in sullen and clogged indifference. They were satisfied with repelling attacks, and nursed their hatred.[18]

Thus the city was divided, and the attempts to check the factions only exasperated them. It was in vain that, when at times the government and the populace lost patience, severe measures were taken. It was in vain that the reformer, Gian della Bella, carried for a time his harsh "orders of justice" against the nobles, and invested popular vengeance with the solemnity of law and with the pomp and ceremony of a public act—that when a noble had been convicted of killing a citizen, the great officer, "Standard-bearer," as he was called, "of justice," issued forth in state and procession, with the banner of justice borne before him, with all his train, and at the head of the armed citizens, to the house of the criminal, and razed it to the ground. An eyewitness describes the effect of such chastisement:—"I, Dino Compagni, being Gonfalonier of Justice in 1293, went to their houses, and to those of their relations, and these I caused to be pulled down according to the laws. This beginning in the case of the other Gonfaloniers came to an evil effect; because, if they demolished the houses according to the laws, the people said that they were cruel; and if they did not demolish them completely, they said that they were cowards; and many distorted justice for fear of the people." Gian della Bella was overthrown with few regrets even on the part of the people. Equally vain was the attempt to keep the peace by separating the leaders of the disturbances. They were banished by a kind of ostracism; they departed in ostentatious meekness, Corso Donato to plot at Rome, Vieri de' Cerchi to return immediately to Florence. Anarchy had got too fast a hold on the city, and it required a stronger hand than that of the pope, or the signory of the republic, to keep it down.

Yet Florence prospered. Every year it grew richer, more intellectual, more refined, more beautiful, more gay. With its anarchy there was no stagnation. Torn and divided as it was, its energy did not slacken, its busy and creative spirit was not deadened, its hopefulness not abated. The factions, fierce and personal as they were, did not hinder that interest in political ideas, that active and subtle study of the questions of civil government, that passion and ingenuity displayed in political contrivance, which now pervaded Northern Italy, everywhere marvellously patient and hopeful, though far from being equally successful. In Venice at the close of the thirteenth century, that polity was finally settled and consolidated, by which she was great as long as cities could be imperial, and which even in its decay survived the monarchy of Louis XIV. and existed within the memory of living men. In Florence, the constructive spirit of law and order only resisted, but never triumphed. Yet it was at this time resolute and sanguine, ready with experiment and change, and not yet dispirited by continual failure. Political interest, however, and party contests were not sufficient to absorb and employ the citizens of Florence. Their genial and versatile spirit, so keen, so inventive, so elastic, which made them such hot and impetuous partisans, kept them from being only this. The time was one of growth; new knowledge, new powers, new tastes were opening to men—new pursuits attracted them. There was commerce, there was the school philosophy, there was the science of nature, there was ancient learning, there was the civil law, there were the arts, there was poetry, all rude as yet, and unformed, but full of hope—the living parents of mightier offspring. Frederick II. had once more opened Aristotle to the Latin world; he had given an impulse to the study of the great monuments of Roman legislation which was responded to through Italy; himself a poet, his example and his splendid court had made poetry fashionable. In the end of the thirteenth century a great stride was made at Florence. While her great poet was growing up to manhood, as rapid a change went on in her streets, her social customs, the wealth of her citizens, their ideas of magnificence and beauty, their appreciation of literature. It was the age of growing commerce and travel; Franciscan missionaries had reached China, and settled there;[19] in 1294, Marco Polo returned to Venice, the first successful explorer of the East. The merchants of Florence lagged not; their field of operation was Italy and the West; they had their correspondents in London, Paris, and Bruges; they were the bankers of popes and kings.[20] And their city shows to this day the wealth and magnificence of the last years of the thirteenth century.
