p. 505 Chapter XIX.—Rejoicings and Festivities.

And now, the impious being thus removed, the sun once more shone brightly after the gloomy cloud of tyrannic power. Each separate portion of the Roman dominion became blended with the rest; the Eastern nations united with those of the West, and the whole body of the Roman empire was graced as it were by its head in the person of a single and supreme ruler, whose sole authority pervaded the whole. Now too the bright rays of the light of godliness gladdened the days of those who had heretofore been sitting in darkness and the shadow of death. Past sorrows were no more remembered, for all united in celebrating the praises of the victorious prince, and avowed their recognition of his preserver as the only true God. Thus he whose character shone with all the virtues of piety, the emperor Victor, for he had himself adopted this name as a most fitting appellation to express the victory which God had granted him over all who hated or opposed him, 3178 assumed the dominion of the East, and thus singly governed the Roman empire, re-united, as in former times, under one head. Thus, as he was the first to proclaim to all the sole sovereignty of God, so he himself, as sole sovereign of the Roman world, extended his authority over the whole human race. Every apprehension of those evils under the pressure of which all had suffered was now removed; men whose heads had drooped in sorrow now regarded each other with smiling countenances, and looks expressive of their inward joy. With processions and hymns of praise they first of all, as they were told, ascribed the supreme sovereignty to God, as in truth the King of kings; and then with continued acclamations rendered honor to the victorious emperor, and the Cæsars, his most discreet and pious sons. The former afflictions were forgotten, and all past impieties forgiven: while with the enjoyment of present happiness was mingled the expectation of continued blessings in the future.

Footnotes

Like very many other things which Eusebius tells of Constantine, that which was entirely customary with other emperors as well as Constantine has the appearance of being peculiar to him. Victor is a common title of various emperors.
