maintain in living energy this moralising influence, to fulfil this her great mission. This necessity must appear clear to every one if there were in the history of Italy and the Papacy no other period than that of the last Lombard times, or that following when the Carlovingian rule was falling to pieces. The foundation of the temporal power was no artificial plan devised by Gregory II. for himself and his successors when he began the great battle against the Iconoclasts. It was a necessity in the world’s history, developing itself rapidly, yet step by step, out of the situation of things both in politics and religion. And as if it should not want a legitimate title also, the new formation rose at a moment when, independently of action on the part of the Popes, the whole claim of the empire practically disappeared in the centre of Italy. It was recognised by the Popes alone even when scarcely anything more remained of it than a mere form and name. CHAPTER VII. ROME’S THREE HUNDRED YEARS, 455-756 FROM GENSERIC TO AISTULF, BETWEEN THE GOTH, THE LOMBARD, AND THE BYZANTINE. I propose to give a continuous review of the Roman pontiff’s position in the city of Peter from the plundering of imperial Rome by the Vandal Genseric in 455 to the siege of papal Rome and desolation of the Campagna by the Lombard king Aistulf, beginning January 1, 756. This attack was followed in that year by the enfranchisement of Rome and the gift of the exarchate by Pipin, king of the Franks, to St. Peter and his successors, when he laid the keys of the cities surrendered by the Lombards on the tomb of the Prince of the Apostles. Three hundred years of suffering unbroken and of glory unsurpassed which preceded the passage of the Roman pontiff from servitude to sovereignty. The sun of imperial Rome set for ever when the degenerate grandson of the great Theodosius, great grandson also of Valentinian, whose name he covered with infamy, perished by the stroke of an assassin in the Campus Martius, the result of a life in which he imitated the crime of Tarquin. But Tarquin’s crime led to Rome’s freedom, the crime of Valentinian III. brought the end of the imperial city, and the substitution of a Rome built upon revealed truth and eternal justice for the Rome of secular pride and unjust conquest. In these three hundred years the brother Apostles, the fisherman and the tentmaker, took the place of the robber brothers, Romulus the slayer, and Remus the slain, when the twelve centuries of augured dominion were exactly fulfilled, and in the time of St. Leo the Great the twelve vultures had had their full flight.
