Only one general remained to the desponding Arcadius,--Stilicho, trained in the armies of Theodosius, who had virtually intrusted to him, although by birth a Vandal, the guardianship of his children. We see in these latter days of the Empire that the best generals were of barbaric birth,--an impressive commentary on the degeneracy of the legions. At the approach of Stilicho, Alaric retired at first, but collecting a force of ten thousand men penetrated the Julian Alps, and advanced into Italy. The Emperor Honorius was obliged to summon to his rescue his dispirited legions from every quarter, even from the fortresses of the Rhine and the Caledonian wall, with which Stilicho compelled Alaric to retire, but only on a subsidy of two tons of gold. The Roman people, supposing that they were delivered, returned to their circuses and gladiatorial shows. Yet Italy was only temporarily delivered, for Stilicho,--the hero of Pollentia,--with the collected forces of the whole western Empire, might still have defied the armies of the Goths and staved off the ruin another generation, had not imperial jealousy and the voice of envy removed him from command. The supreme guardian of the western Empire, in the greatest crisis of its history, himself removes the last hope of Rome. The frivolous senate which Stilicho had saved, and the weak and timid emperor whom he guarded, were alike demented. Quos Deus vult perdere, prius dementat. In an evil hour the brave general was assassinated.

The Gothic king observing the revolutions at the palace, the elevation of incompetent generals, and the general security in which the people indulged, resolved to march to a renewed attack. Again he crossed the Alps, with a still greater army, and invaded Italy, destroying everything in his path. Without obstruction he crossed the Apennines, ravaged the fertile plains of Umbria, and reached the city, which for four hundred years had not been violated by the presence of a foreign enemy. The walls were then twenty-five miles in circuit, and contained so large a population that it affected indifference. Alaric made no attempt to take the city by storm, but quietly and patiently enclosed it with a cordon through which nothing could force its way,--as the Prussians in our day invested Paris. The city, unprovided for a siege, soon felt all the evils of famine, to which pestilence was naturally added. In despair, the haughty citizens condescended to sue for a ransom. Alaric fixed the price of his retreat at the surrender of all the gold and silver, all the precious movables, and all the slaves of barbaric birth. He afterwards somewhat modified his demands, but marched away with more spoil than the Romans brought from Carthage and Antioch.

Honorius intrenched himself at Ravenna, and refused to treat with the magnanimous Alaric. Again, consequently, he marched against the doomed capital; again invested it; again cut off supplies. In vain did the nobles organize a defence,--there were no defenders. Slaves would not fight, and a degenerate rabble could not resist a warlike and superior race. Cowardice and treachery opened the gates. In the dead of night the Gothic trumpets rang unanswered in the streets. The old heroic virtues were gone. No resistance was made. Nobody fought from temples and palaces. The queen of the world, for five days and nights, was exposed to the lust and cupidity of despised barbarians. Yet a general slaughter was not made; and as much wealth as could be collected into the churches of St. Peter and St. Paul was spared. The superstitious barbarians in some degree respected churches. But the spoils of the city were immense and incalculable,--gold, jewels, vestments, statues, vases, silver plate, precious furniture, spoils of Oriental cities,--the collective treasures of the world,--all were piled upon the Gothic wagons. The sons and daughters of patrician families became, in their turn, slaves to the barbarians. Fugitives thronged the shores of Syria and Egypt, begging daily bread. The Roman world was filled with grief and consternation. Its proud capital was sacked, since no one would defend it. "The Empire fell," says Guizot, "because no one belonged to it." The news of the capture "made the tongue of old Saint Jerome to cling to the roof of his mouth in his cell at Bethlehem. What is now to be seen," cried he, "but conflagration, slaughter, ruin,--the universal shipwreck of society?" The same words of despair came from Saint Augustine at Hippo. Both had seen the city in the height of its material grandeur, and now it was laid low and desolate. The end of all things seemed to be at hand; and the only consolation of the great churchmen of the age was the belief in the second coming of our Lord.

The sack of Rome by Alaric, A.D. 410, was followed in less than half a century by a second capture and a second spoliation at the hands of the Vandals, with Genseric at their head,--a tribe of barbarians of kindred Germanic race, but fiercer instincts and more hideous peculiarities. This time, the inhabitants of Rome (for Alaric had not destroyed it,--only robbed it) put on no airs of indifference or defiance. They knew their weakness. They begged for mercy.

The last hope of the city was her Christian bishop; and the great Leo, who was to Rome what Augustine had been to Carthage when that capital also fell into the hands of Vandals, hastened to the barbarian's camp. The only concession he could get was that the lives of the people should be spared,--a promise only partially kept. The second pillage lasted fourteen days and nights. The Vandals transferred to their ships all that the Goths had left, even to the trophies of the churches and ancient temples; the statues which ornamented the capital, the holy vessels of the Jewish temple which Titus had brought from Jerusalem, imperial sideboards of massive silver, the jewels of senatorial families, with their wives and daughters,--all were carried away to Carthage, the seat of the new Empire of the Vandals, A.D. 455, then once more a flourishing city. The haughty capital met the fate which she had inflicted on her rival in the days of Cato the censor, but fell still more ingloriously, and never would have recovered from this second fall had not her immortal bishop, rising with the greatness of the crisis, laid the foundation of a new power,--that spiritual domination which controlled the Gothic nations for more than a thousand years.

With the fall of Rome,--yet too great a city to be wholly despoiled or ruined, and which has remained even to this day the centre of what is most interesting in the world,--I should close this Lecture; but I must glance rapidly over the whole Empire, and show its condition when the imperial capital was spoiled, humiliated, and deserted.

The Suevi, Alans, and Vandals invaded Spain, and erected their barbaric monarchies. The Goths were established in the south of Gaul, while the north was occupied by the Franks and Burgundians. England, abandoned by the Romans, was invaded by the Saxons, who formed permanent conquests. In Italy there were Goths and Heruli and Lombards. All these races were Germanic. They probably made serfs or slaves of the old population, or were incorporated with them. They became the new rulers of the devastated provinces; and all became, sooner or later, converts to a nominal Christianity, the supreme guardian of which was the Pope, whose authority they all recognized. The languages which sprang up in Europe were a blending of the Roman, Celtic, and Germanic. In Spain and Italy the Latin predominated, as the Saxon prevailed in England after the Norman conquest. Of all the new settlers in the Roman world, the Normans, who made no great incursions till the time of Charlemagne, were probably the strongest and most refined. But they all alike had the same national traits, substantially; and they entered upon the possessions of the Romans after various contests, more or less successful, for two hundred and fifty years.

The Empire might have been invaded by these barbarians in the time of the Antonines, and perhaps earlier; but it would not have succumbed to them. The Legions were then severely disciplined, the central power was established, and the seeds of ruin had not then brought forth their wretched fruits. But in the fifth century nothing could have saved the Empire. Its decline had been rapid for two hundred years, until at last it became as weak as the Oriental monarchies which Alexander subdued. It fell like a decayed and rotten tree. As a political State all vitality had fled from it. The only remaining conservative forces came from Christianity; and Christianity was itself corrupted, and had become a part of the institutions of the State.

It is mournful to think that a brilliant external civilization was so feeble to arrest both decay and ruin. It is sad to think that neither art nor literature nor law had conservative strength; that the manners and habits of the people grew worse and worse, as is universally admitted, amid all the glories and triumphs and boastings of the proudest works of man. "A world as fair and as glorious as our own," says Sismondi, "was permitted to perish." Rome, Alexandria, Antioch, Athens, met the old fate of Babylon, of Tyre, of Carthage. Degeneracy was as marked and rapid in the former, notwithstanding all the civilizing influences of letters, jurisprudence, arts, and utilitarian science, as in the latter nations,--a most significant and impressive commentary on the uniform destinies of nations, when those virtues on which the strength of man is based have passed away. An observer in the days of Theodosius would very likely have seen the churches of Rome as fully attended as are those in New York itself to-day; and he would have seen a more magnificent city,--and yet it fell. There is no cure for a corrupt and rotten civilization. As the farms of the old Puritans of Massachusetts and Connecticut are gradually but surely passing into the hands of the Irish, because the sons and grandsons of the old New-England farmer prefer the uncertainties and excitements of a demoralized city-life to laborious and honest work, so the possessions of the Romans passed into the hands of German barbarians, who were strong and healthy and religious. They desolated, but they reconstructed.

The punishment of the enervated and sensual Roman was by war. We in America do not fear this calamity, and have no present cause of fear, because we have not sunk to the weakness and wickedness of the Romans, and because we have no powerful external enemies. But if amid our magnificent triumphs of science and art, we should accept the Epicureanism of the ancients and fall into their ways of life, then there would be the same decline which marked them,--I mean in virtue and public morality,--and there would be the same penalty; not perhaps destruction from external enemies, as in Persia, Syria, Greece, and Rome, but some grievous and unexpected series of catastrophes which would be as mournful, as humiliating, as ruinous, as were the incursions of the Germanic races. The operations of law, natural and moral, are uniform. No individual and no nation can escape its penalty. The world will not be destroyed; Christianity will not prove a failure,--but new forces will arise over the old, and prevail. Great changes will come. He whose right it is to rule will overturn and overturn: but "creation shall succeed destruction; melodious birth-songs will come from the fires of the burning phoenix," assuring us that the progress of the race is certain, even if nations are doomed to a decline and fall whenever conservative forces are not strong enough to resist the torrent of selfishness, vanity, and sin.
