Romanus was succeeded by Callinicus (Gallicinus) in whom the pope found a more congenial and perhaps a more reasonable spirit. By 598 an armistice had been officially concluded between the imperialists and the Lombards, and at length in 599, after some foolish delays in which it would appear that the pope was not without blame, a peace was concluded. Gregory, however, for all his reluctance at the last, had won his way. Henceforth it would be impossible to regard the Lombards as mere invaders after the pattern of their predecessors, Visigoths, Vandals, Huns, and Ostrogoths. They were, or would shortly be, a Catholic people; they held a very great part of Italy; they had entered into a treaty with the emperor not as _foederati_ but as equals and conquerors. Gregory the Great had permanently established the barbarians in Italy, and in his act, the act be it remembered of the apostle of the English, of the apostle of the Lombards, we seem to see the shadowy power that had been Leo's by the Mincio suddenly appear, a new glory in the world. The new power in the West, the papacy, which thus shines forth really for the first time in the acts of Gregory, unlike the empire, whether Roman or Byzantine, will know no frontiers, but will go into all the world and compel men to come in as its divine commission ordained. In Italy from the time of the peace with the Lombards (599) onwards what we see is the decline of the imperial power of Constantinople and the rise of the papacy. And this was brought about not only by the circumstances in which Italy and the West found themselves, but also by the character of the imperial government. When Justin II. disappeared in 578, and made way for Tiberius II., he was already a madman, and though Tiberius was renowned for his virtues, he reigned but four years, and in 582 Maurice the Cappadocian sat upon the throne of Justinian and ruled for twenty years not unwisely, but, so far as Italy was concerned, without success. It was he who was at last brought to make peace with the Lombards and thus for the first time to acknowledge a barbarian state independent of the empire in Italy. He and his children were all murdered in 602 by Phocas, a centurion, whose shame and crimes and cruelties doubtless did much to weaken the moral power of the empire face to face with the papacy. The peace of 599, the usurpation of Phocas in 602, and the death of Gregory the Great in 604, close a great period and stamp the seventh century in its very beginning with a new character.
