p. 496 Chapter XLIX.—How Licinius oppressed the East.
For he was informed that in that quarter a certain savage beast was besetting both the church of God and the other inhabitants of the provinces, owing, as it were, to the efforts of the evil spirit to produce effects quite contrary to the deeds of the pious emperor: so that the Roman empire, divided into two parts, seemed to all men to resemble night and day; since darkness overspread the provinces of the East, while the brightest day illumined the inhabitants of the other portion.
