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.

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.
