At the same time, as a compensation, perhaps, for the expenses of the war, the Western Illyricum was detached from the Italian dominions, and yielded to the throne of Constantinople.

The emperor of the East acquired the useful dominion of the rich and maritime province of Dalmatia, and the dangerous sovereignty of Pannonia and Noricum, which had been filled and ravaged above twenty years by a promiscuous crowd of Huns, Ostrogoths, Vandals, and _Bavarians_.

Theodosius and Valentinian continued to respect the obligations of their public and domestic alliance; but the unity of the Roman government was finally dissolved.

By a positive declaration, the validity of all future laws was limited to the dominions of their peculiar author; unless he should think proper to communicate them, subscribed with his own hand, for the approbation of his independent colleague.

Placidia envied, but she could not equal, the reputation and virtues of the wife and sister of Theodosius, the elegant genius of Eudocia, the wise and successful policy of Pulcheria.
