when the plague was thus conveyed across the sea, all the venom of every heresy immediately rushed into the island, ever fond of something new, and never holding firm to anything.
At this time, Constantius, who, whilst Diocletian was alive, governed Gaul and Spain, a man of extraordinary meekness and courtesy, died in Britain. This man left his son Constantine, born of Helen his concubine, emperor of the Gauls. Eutropius writes, that Constantine, being created emperor in Britain, succeeded his father in the sovereignty. In his time the Arian heresy broke out, and although it was detected and condemned in the Council of Nice, yet it nevertheless infected not only all the churches of the continent, but even those of the islands, with its pestilent and fatal doctrines.
CHAPTER IX
In the year of our Lord's incarnation, 377, Gratian, the fortieth from Augustus, held the empire six years after the death of Valens; though he had long before reigned with his uncle Valens, and his brother Valentinian. Finding the state of the commonwealth much impaired, and almost gone to ruin, he looked around for some one whose abilities might remedy the existing evils; and his choice fell on Theodosius, a Spaniard. Him he invested at Sirmium with the royal robes, and made him emperor of Thrace and the Eastern provinces. At which time, Maximus, a man of valour and probity, and worthy to be an emperor, if he had not broken the oath of allegiance which he had taken, was made emperor by the army, passed over into Gaul, and there by treachery slew the Emperor Gratian, who was in a consternation at his sudden invasion, and attempting to escape into Italy. His brother, Valentinian, expelled from Italy, fled into the East, where he was entertained by Theodosius with fatherly affection, and soon restored to the empire. Maximus the tyrant, being shut up in Aquileia, was there taken and put to death.
