The universities and schools which were already founded obtained more fame and became more active. The clash of arms, which had not prevented their flourishing, did not prevent new ones being formed. That same spirit of rivalry which armed one against the other, princes and nations, led them to vie one with the other in seeking, by every means, greater renown and greater glory for their little states. At one time professors were seen quietly continuing their lectures while fighting was going on under the walls of the town, or even in the streets and squares; at another time, the rostrum was overthrown, the professors were driven away, the scholars put to flight; but they soon returned, either under the same government or under the new one which had taken its place, and studies continued their course. The University of Bologna suffered continual vicissitudes. At one time excommunicated by Clement V, the greater number of the scholars passed to the University of Padua, Bologna’s rival; at another time, in consequence of quarrels which broke out between the professors and the magistrates, or between the scholars and the citizens, whole classes deserted and settled in the neighbouring towns. But all these wrongs were righted. John XXII withdrew Clement’s interdict, and confirmed and increased the privileges of the university; the magistrates and citizens granted the amends demanded by professors and pupils; and this school, which was already famous, became more brilliant and more famous. A short time later, Milan, Pisa, Pavia, Piacenza, Siena, but especially Florence, rivalled with Padua, Bologna, and the University of Naples founded by Frederick II, which had so vastly increased under Robert of Naples. Boniface VIII had founded the University of Rome, his successors confirmed and even extended its privileges; but their bulls could not repair the harm done to the new university by their absence; it could not do aught but decline so long as their residence at Avignon left the unfortunate town of Rome almost deserted, and, as a climax, always a prey to sedition and torn by internal factions.
