The highest state of prosperity is reached that the ancient world knew, and all bow down to Caesar and behold in him the representative of divine providence, from whose will there is no appeal, and from whose arm it is impossible to fly. But _mene, mene, tekel, upharsin_, is written on the walls of the banqueting chambers of the palace of the Caesars. The dream of omnipotence is disturbed by the invasion of, Germanic barbarians. They press toward the old seats of power and riches to improve their condition. They are warlike, fierce, implacable. They fear not death, and are urged onward by the lust of rapine and military zeal. The old legions, which penetrated the Macedonian phalanx and withstood the Gauls, cannot resist the shock of their undisciplined armies; for martial glory has fled, and the people prefer their pleasures to the empire. Great emperors are raised up, but they are unequal to the task of preserving the crumbling empire. The people, enervated and egotistical, are scattered like sheep or are made slaves. The proud capitals of the world fall before the ruthless invaders. Desolation is everywhere. The barbarians trample beneath their heavy feet the proud trophies of ancient art and power. The glimmering life-sparks of the old civilization disappear. The world is abandoned to fear, misery, and despair, and there is no help, for retributive justice marches on with impressive solemnity. Imperial despotism, disproportionate fortunes, unequal divisions of society, the degradation of woman, slavery, Epicurean pleasures, practical atheism, bring forth their wretched fruits. The vices and miseries of society cannot be arrested. Glory is succeeded by shame; all strength is in mechanism, and that wears out; vitality passes away; the empire is weak from internal decay, and falls easily into the hands of the new races. "Violence was only a secondary cause of the ruin; the vices of self-interest were the primary causes. A world, as fair and glorious as our own, crumbles away." Our admiration is changed to sadness and awe. The majesty of man is rebuked by the majesty of God. Such a history is suggestive. Why was such an empire permitted to rise over the bleeding surface of the world, and what was its influence on the general destiny of the race? How far has its civilization perished, and how far has it entered into new combinations? Was its strength material, or moral, or intellectual? How far did literature, art, science, laws, philosophy, prove conservative forces? Why did Christianity fail to arrest so total an eclipse of the glory of man? Why did a magnificent civilization prove so feeble a barrier against corruption and decay? Why was the world to be involved in such universal gloom and wretchedness as followed the great catastrophe? Could nothing arrest the stupendous downfall?
