great period was beginning, when the wandering of the nations had prepared for the Church another task. The first had been to obtain the conversion of nations linked by the bond of one temporal rule, enjoying the highest degree of culture and knowledge then existing, but deeply tainted by the corruption of effete refinement. The second was to exalt rough, sturdy, barbarian natures, whose bride was the sword and human life their prey, first to the virtues of the civil state, and next to the higher life of Christian charity, and thus to link them, who had known only violent repulsion and perpetual warfare among themselves, in not a temporal but a spiritual bond. The majestic figure of St. Leo expressed the completion of the first task. It also symbolises the beneficent power which in the course of ages will accomplish the second. The wandering of the nations, says a great historian, was of decisive effect for the Church, and he quotes another historian's summary description of it: "It was not the migration of individual nomad hordes, or masses of adventurous warriors in continuous motion, which produced changes so mighty. But great, long-settled peoples, with wives and children, with goods and chattels, deserted their old seats, and sought for themselves in the far distance a new home. By this the position of individuals, of communities, of whole peoples, was of necessity completely altered. The old conditions of possession were dissolved. The existing bonds of society loosened. The old frontiers of states and lands passed away. As a whole city is turned into a ruinous heap by an earthquake, so the whole political system of previous times was overthrown by this massive transmigration. A new order of things had to be formed corresponding to the wholly altered circumstances of the nation."[17]
