But the desertion of his confederates, who were privately convinced of the justice and liberality of the Imperial ministers, obliged Uldin to repass the Danube: the tribe of the Scyrri, which composed his rear-guard, was almost extirpated; and many thousand captives were dispersed to cultivate, with servile labor, the fields of Asia.

In the midst of the public triumph, Constantinople was protected by a strong enclosure of new and more extensive walls; the same vigilant care was applied to restore the fortifications of the Illyrian cities; and a plan was judiciously conceived, which, in the space of seven years, would have secured the command of the Danube, by establishing on that river a perpetual fleet of two hundred and fifty armed vessels.
But the Romans had so long been accustomed to the authority of a monarch, that the first, even among the females, of the Imperial family, who displayed any courage or capacity, was permitted to ascend the vacant throne of Theodosius.

His sister Pulcheria, who was only two years older than himself, received, at the age of sixteen, the title of _Augusta_; and though her favor might be sometimes clouded by caprice or intrigue, she continued to govern the Eastern empire near forty years; during the long minority of her brother, and after his death, in her own name, and in the name of Marcian, her nominal husband.

From a motive either of prudence or religion, she embraced a life of celibacy; and notwithstanding some aspersions on the chastity of Pulcheria, this resolution, which she communicated to her sisters Arcadia and Marina, was celebrated by the Christian world, as the sublime effort of heroic piety.

In the presence of the clergy and people, the three daughters of Arcadius dedicated their virginity to God; and the obligation of their solemn vow was inscribed on a tablet of gold and gems; which they publicly offered in the great church of Constantinople.
