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. The ancient buildings, consecrated in the memory of the Florentine people, were repaired, enlarged, adorned with marble and
