But from the Age of Darkness men awoke both in their manners and in their buildings. Perugia of the Middle Ages shook the sleep from off her heavy eyelids, and with that passionate impulse towards Light which was perhaps the secret of the Renaissance, she too strove toward the Beautiful, and in a hurried, fevered fashion, she too decked herself with fairer things than castle towers and hovels. The fourteenth and the fifteenth centuries were, as we know, the Age of Gold in later art, and Perugia, in spite of all her tumults, in spite of her feuds, and even her passionate religious abstinences, woke with the waking world. Most of her churches, and most of those monuments which mark her as a point for travellers, date from that period. "And at that time," says the chronicler Fabretti, "there was so great a building going on in different parts of the city that neither mortar nor stones nor masons could have been procured even for money, unless a number of Lombards had come in to build. And they were building the palace of the _Priori_ (Palazzo Pubblico), they were building S. Lorenzo, Santa Maria dei Servi, S. Domenico, S. Francesco, the houses of Messer Raniero ... the tower of the Palazzo, and numerous other houses of private citizens all at that same time."
But it was not merely a love of beauty which prompted the Perugians to this sudden departure in the way of architecture; the spirit of the great saint of Umbria had much to do with it. In Perugian chronicles and histories we find a strange silence about the influence of S. Francis on a city which was only separated by some fourteen miles from Assisi. Yet it is not possible that so strong a force as that of this man's preaching could have been kept outside the walls of the neighbour town, and Ciatti declares that at one time nearly a third part of the inhabitants of Perugia took the Franciscan habit. In 1500 and 1600 there were more than fifty convents in Perugia, many of which had sixty to eighty inhabitants, but that was during the rule of the popes. Of the great period of building in the fourteenth century, which included many fine churches and convents, the buildings of the people and not of the priests remain intact. The splendid Palazzo Pubblico and Pisano's fountain in the square belong to this period. But because the work of the Renaissance is so conspicuous and charming we have described it in another place, and in our description of the town have lingered rather over the fragments of the Etruscan and the mediæval city.
