To such a tribute I can add nothing. His greatness consists in this, that, born amidst barbarism, he was yet the friend of civilization, and understood its elemental principles, and struggled forty-seven years to establish them,--failing only because his successors and subjects were not prepared for them, and could not learn them until the severe experience of ten centuries, amidst disasters and storms, should prove the value of the "old basal walls and pillars" which remained unburied amid the despised ruins of antiquity, and show that no structure could adequately shelter the European nations which was not established by the beautiful union of German vigor with Christian art,--by the combined richness of native genius with those immortal treasures which had escaped the wreck of the classic world.

We associate with Hildebrand the great contest of the Middle Ages between spiritual and temporal authority, the triumph of the former, and its supremacy in Europe until the Reformation. What great ideas and events are interwoven with that majestic domination,--not in one age, but for fifteen centuries; not religious merely, but political, embracing as it were the whole progress of European society, from the fall of the Roman Empire to the Protestant Reformation; yea, intimately connected with the condition of Europe to the present day, and not of Europe only, but America itself! What an august power is this Catholic empire, equally great as an institution and as a religion! What lessons of human experience, what great truths of government, what subtile influences, reaching alike the palaces of kings and the hovels of peasants, are indissolubly linked with its marvellous domination, so that whether in its growth or decay it is more suggestive than the rise and fall of any temporal empire. It has produced, probably, more illustrious men than any political State in Europe. It has aimed to accomplish far grander ends. It is invested with more poetic interest. Its policy, its heroes, its saints, its doctors, its dignitaries, its missions, its persecutions, all rise up before us with varied but never-ending interest, when seriously contemplated.
