Constantine ‘the Great’ died in 337, and if greatness be measured by achievement he well deserves his title. Where men of higher genius and originality had failed he had succeeded, beating down with calm perseverance every object that threatened his ambitions, until at last the Christian ruler of a united empire, feared and respected by subjects and enemies alike, he passed to his rest. V THE INVASIONS OF THE BARBARIANS Instead of endeavouring to maintain a united empire, Constantine in his will divided up his dominions between three sons and two nephews. Before thirty years were over, however, a series of murders and civil wars had exterminated his family; and two brothers, Valentian and Valens, men of humble birth but capable soldiers, were elected as joint emperors. Valens ruled at Constantinople, his brother at Milan; and it was during this reign that the Empire received one of the worst blows that had ever befallen her. We have already mentioned the Goths, a race of barbarians half-civilized by Roman influence and converted to Christianity by followers of Arius. One of their tribes, the Visigoths, had settled in large numbers in the country to the north of the Danube. On the whole their relations with the Empire were friendly, and it was hardly their fault that the peace was finally broken, but rather of a strange Tartar race the Huns, that, massing in the plains of Asia, had suddenly swept over Europe. Here is a description given of the Huns by a Gothic writer: ‘Men with faces that can scarcely be called faces, rather shapeless black collops of flesh with tiny points instead of eyes: little in stature but lithe and active, skilful in riding, broad-shouldered, hiding under a barely human form the ferocity of a wild beast.’ Tradition says that these monsters, mounted on their shaggy ponies, rode women and children under foot and feasted on human flesh. Whether this be true or no, their name became a terror to the civilized world, and after a few encounters with them the Visigoths crowded on the edge of the Danube and implored the Emperor to allow them to shelter behind the line of Roman forts. Valens, to whom the petition was made, hesitated. There was obvious danger to his dominions in this sudden influx of a whole tribe; but on the other hand fear might madden the Visigoths into trying to cross even if he refused, and if so could he withstand them? ‘All the multitude that had escaped from the murderous savagery of the Huns,’ says a writer of the day, ‘no less than 200,000 fighting men besides women and old men and children, were there on the river bank, stretching out their hands with loud lamentations ... and promising that they would ever faithfully adhere to the imperial alliance, if only the boon was granted them.’
