Fritigern, the conqueror of Hadrianopolis, was dead; the gallant Athanaric, his successor, had allowed himself to be allured to Constantinople, and there, dazzled by the brilliance of the gorgeous court, he persuaded his people to accept the emperor’s offers (October, 382). Theodosius, as a matter of fact, gave them what they wanted. He settled them in Thrace and Mœsia, with the charge of defending the passage of the Danube. Forty thousand warriors of the Goths were enrolled among the imperial troops.
This was really to deliver the empire into their hands; for these Goths—remaining a national body under their national leaders, with a military organisation of their own—soon felt the instincts of pillage and the need of adventure reawaken in them. A few years more, and they would take Rome after ravaging Greece and Italy, and the war they would thus carry to the very heart of the empire would level the barriers over which this flood of invasion was destined to pass.
For the time being, however, Theodosius had put an end to a deplorable situation, and the empire, believing itself saved, showed its gratitude. Those sad events of which the West was the scene, and which would lead to a reunion of the whole empire of Augustus under his authority, for a while increased his renown. The church, above all, delivered by him from Arianism, looked upon him as a second Constantine, and the epithet of “the great” has remained joined to the name of the last master of the Roman world.
Gratian, active, intelligent, and brave, was nevertheless overthrown by a usurper. Passionately fond of hunting, he forgot his princely duties, and was now usually seen surrounded by Alan archers. This preference irritated the soldiers, and the British legions proclaimed their chief, Maximus, one of the able comrades of Count Theodosius, emperor. Maximus immediately marched into Gaul. Gratian, abandoned by his troops, tried to reach the Alps, but, being overtaken near Lyons, he was put to death (August 25, 383). For this expedition Maximus had withdrawn the legions from Britain. The island, left defenceless, was soon desolated by the inroads of the Picts and Scots, and by the invasions of Saxons and Frisians.
Theodosius would gladly have avenged his benefactor, but tranquillity was not yet restored in the East, and a civil war might have lost all. He recognised the usurper as master of the Gallic prefecture on condition that he should leave that of Italy to the young Valentinian II (385). The latter’s mother, Justina, in her zeal for Arianism, sought to propagate heresy in her son’s provinces, which were by no means favourably disposed towards it. At Mediolanum the opposition was very strong. She tried to overcome it by threatening to exile Saint Ambrose, the archbishop, but the people repulsed her barbarian guards. Maximus thought the occasion favourable. He crossed the Alps, and Valentinian II fled (387) to Theodosius at Thessalonica.
This prince had already declared himself strongly opposed to the Arians. As early as the year 380 he had received baptism, had promulgated edicts in favour of orthodoxy, and expelled Damophilus, patriarch of Constantinople, from his see, which was given to Gregory of Nazianzus. A council which met in Constantinople (381) condemned the heresy afresh and confirmed the Nicene creed. Justina owed her misfortunes to her zeal for Arianism, but Theodosius had married her daughter, the beautiful Galla, so the empress, despite her imprudence, could count on the support of her son-in-law. He hesitated, however, for nearly a year until he learned that Maximus by his harshness had stirred up all the Italians against him.
THEODOSIUS FORBIDDEN THE TEMPLE BY SAINT AMBROSE
[388-395 A.D.]
Theodosius entered Pannonia in the year 388, and made a diversion in Gaul by means of the Saxons and Franks. Maximus used the same weapons against him and tampered with the fidelity of his barbaric troops. Dangerous defections would have ensued had he not anticipated them by severe measures. The usurper, vanquished on the banks of the Save, was given up by his own soldiers and put to death in Aquileia. Theodosius kept no part of his conquest, but gave it up to Valentinian. To confirm the young prince’s power and extirpate both heresy and the last remains of paganism which yet lingered in the Western provinces, he stayed three years in his brother-in-law’s province. On his departure he gave him as chief minister Arbogast the Frank, who had just delivered Gaul from the Germans, and filled all offices, civil and military, with barbarians. Valentinian did not long endure this guardianship; he wished to deprive the count of all his offices. “I hold my charge from Theodosius,” answered Arbogast before the whole court, “he alone can take it from me.” Valentinian, in a violent rage, threw himself upon Arbogast, sword in hand. Some days after he was found dead (May 15, 392).
