Nicene and Post-Nicene Fathers: Series II/Volume II/Sozomen/Book VII/Chapter 1
Book VII.
Chapter I.—When the Romans are pressed by the Barbarians, Mavia sends Assistance, and some of the Populace effect a Victory. Gratian commands each to believe as he wishes.
Such was the fate of Valens. The barbarians,[1]
flushed with victory, overran Thrace, and advanced to the gates of
Constantinople. In this emergency, a few of the confederate Saracens
sent by Mavia, together with many of the populace, were of great
service. It is reported that Dominica, wife of Valens, furnished money
out of the public treasury, and some of the people, after hastily
arming themselves, attacked the barbarians, and drove them from the
city.
Gratian, who at this period reigned conjointly with his brother over the whole Roman Empire, disapproved of the late persecution that had been carried on to check the diversity in religious creeds, and recalled all those who had been banished on account of their religion. He also enacted a law by which it was decreed that every individual should be freely permitted the exercise of his own religion, and should be allowed to hold assemblies, with the exception of the Manichæans and the followers of Photinus and Eunomius.[2]
