How could they realise the threatened danger? Rome made a fine showing of outward glory. Well-paved roads connected the different provinces, the imperial police were active and showed little tenderness for highwaymen. The frontier was closely guarded against the savage tribes who seemed to be occupying the waste lands of northern Europe. The whole world was paying tribute to the mighty city of Rome, and a score of able men were working day and night to undo the mistakes of the past and bring about a return to the happier conditions of the early Republic.

But the underlying causes of the decay of the State, of which I have told you in a former chapter, had not been removed and reform therefore was impossible.

Rome was, first and last and all the time, a city-state as Athens and Corinth had been city-states in ancient Hellas. It had been able to dominate the Italian peninsula. But Rome as the ruler of the entire civilised world was a political impossibility and could not endure. Her young men were killed in her endless wars. Her farmers were ruined by long military service and by taxation. They either became professional beggars or hired themselves out to rich landowners who gave them board and lodging in exchange for their services and made them "serfs," those unfortunate human beings who are neither slaves nor freemen, but who have become part of the soil upon which they work, like so many cows, and the trees.

The Empire, the State, had become everything. The common citizen had dwindled down to less than nothing. As for the slaves, they had heard the words that were spoken by Paul. They had accepted the message of the humble carpenter of Nazareth. They did not rebel against their masters. On the contrary, they had been taught to be meek and they obeyed their superiors. But they had lost all interest in the affairs of this world which had proved such a miserable place of abode. They were willing to fight the good fight that they might enter into the Kingdom of Heaven. But they were not willing to engage in warfare for the benefit of an ambitious emperor who aspired to glory by way of a foreign campaign in the land of the Parthians or the Numidians or the Scots.

And so conditions grew worse as the centuries went by. The first Emperors had continued the tradition of "leadership" which had given the old tribal chieftains such a hold upon their subjects. But the Emperors of the second and third centuries were Barrack-Emperors, professional soldiers, who existed by the grace of their body-guards, the so-called They succeeded each other with terrifying rapidity, murdering their way into the palace and being murdered out of it as soon as their successors had become rich enough to bribe the guards into a new rebellion.

Meanwhile the barbarians were hammering at the gates of the northern frontier. As there were no longer any native Roman armies to stop their progress, foreign mercenaries had to be hired to fight the invader. As the foreign soldier happened to be of the same blood as his supposed enemy, he was apt to be quite lenient when he engaged in battle. Finally, by way of experiment, a few tribes were allowed to settle within the confines of the Empire. Others followed. Soon these tribes complained bitterly of the greedy Roman tax-gatherers, who took away their last penny. When they got no redress they marched to Rome and loudly demanded that they be heard.

This made Rome very uncomfortable as an Imperial residence. Constantine (who ruled from 323 to 337) looked for a new capital. He chose Byzantium, the gate-way for the commerce between Europe and Asia. The city was renamed Constantinople, and the court moved eastward. When Constantine died, his two sons, for the sake of a more efficient administration, divided the Empire between them. The elder lived in Rome and ruled in the west. The younger stayed in Constantinople and was master of the east.

Then came the fourth century and the terrible visitation of the Huns, those mysterious Asiatic horsemen who for more than two centuries maintained themselves in Northern Europe and continued their career of bloodshed until they were defeated near Chalons-sur-Marne in France in the year 451. As soon as the Huns had reached the Danube they had begun to press hard upon the Goths. The Goths, in order to save themselves, were thereupon obliged to invade Rome. The Emperor Valens tried to stop them, but was killed near Adrianople in the year 378. Twenty-two years later, under their king, Alaric, these same West Goths marched westward and attacked Rome. They did not plunder, and destroyed only a few palaces. Next came the Vandals, and showed less respect for the venerable traditions of the city. Then the Burgundians. Then the East Goths. Then the Alemanni. Then the Franks. There was no end to the invasions. Rome at last was at the mercy of every ambitious highway robber who could gather a few followers.

In the year 402 the Emperor fled to Ravenna, which was a sea-port and strongly fortified, and there, in the year 475, Odoacer, commander of a regiment of the German mercenaries, who wanted the farms of Italy to be divided among themselves, gently but effectively pushed Romulus Augustulus, the last of the emperors who ruled the western division, from his throne, and proclaimed himself Patriarch or ruler of Rome. The eastern Emperor, who was very busy with his own affairs, recognised him, and for ten years Odoacer ruled what was left of the western provinces.

A few years later, Theodoric, King of the East Goths, invaded the newly formed Patriciat, took Ravenna, murdered Odoacer at his own dinner table, and established a Gothic Kingdom amidst the ruins of the western part of the Empire. This Patriciate state did not last long. In the sixth century a motley crowd of Longobards and Saxons and Slavs and Avars invaded Italy, destroyed the Gothic kingdom, and established a new state of which Pavia became the capital.

Then at last the imperial city sank into a state of utter neglect and despair. The ancient palaces had been plundered time and again. The schools had been burned down. The teachers had been starved to death. The rich people had been thrown out of their villas which were now inhabited by evil-smelling and hairy barbarians. The roads had fallen into decay. The old bridges were gone and commerce had come to a standstill. Civilisation—the product of thousands of years of patient labor on the part of Egyptians and Babylonians and Greeks and Romans, which had lifted man high above the most daring dreams of his earliest ancestors, threatened to perish from the western continent.

It is true that in the far east, Constantinople continued to be the centre of an Empire for another thousand years. But it hardly counted as a part of the European continent. Its interests lay in the east. It began to forget its western origin. Gradually the Roman language was given up for the Greek. The Roman alphabet was discarded and Roman law was written in Greek characters and explained by Greek judges. The Emperor became an Asiatic despot, worshipped as the god-like kings of Thebes had been worshipped in the valley of the Nile, three thousand years before. When missionaries of the Byzantine church looked for fresh fields of activity, they went eastward and carried the civilisation of Byzantium into the vast wilderness of Russia.

As for the west, it was left to the mercies of the Barbarians. For twelve generations, murder, war, arson, plundering were the order of the day. One thing—and one thing alone—saved Europe from complete destruction, from a return to the days of cave-men and the hyena.

This was the church—the flock of humble men and women who for many centuries had confessed themselves the followers of Jesus, the carpenter of Nazareth, who had been killed that the mighty Roman Empire might be saved the trouble of a street-riot in a little city somewhere along the Syrian frontier.
