The king of the Persians was laying hands on Armenia, hastening with mighty efforts to bring that country again under his sway, under the false pretext that after the death of Jovian, with whom he had concluded a treaty of peace, nothing ought to prevent his recovery of what he claimed had formerly belonged to his forefathers.
So, then, the emperors spent the winter quietly in perfect harmony, the one eminent through the choice that had fallen upon him, the other joined with him in the office, but only in appearance. After hastening through Thrace, they came to Naessus,[*](Cf. xxi. 10, 5.) where in a suburb called Mediana, distant three miles from the city, they shared the generals between them in view of their coming separation.
To Valentinian, in accordance with whose wish the matter was settled, fell Jovinus,
At the same time Aequitius,[*](See xxvi. 1, 4.) who was not yet a commander-in-chief,[*](He was later made magister armorum; see § 11, below.) but only a count, was put in charge of the army in Illyricum, and Serenianus, who some time before had been retired from service, being a Pannonian[*](Hence a fellow-countryman of Valentinian and Valens.) girded on his sword and was joined with Valens in command of a part of the bodyguard. After matters had been thus arranged, the troops also were divided between the two emperors.
And when after this the two brothers had entered Sirmium, after sharing the places of residence according to the wishes of the superior, Valentinian went off to Mediolanum, Valens to Constantinople.
The Orient was governed by Salutius with the rank of prefect, Italy with Africa and Illyricum by Mamertinus, and the Gallic provinces by Germanianus.
Living therefore in the cities named, the emperors for the first time assumed the consular robes; and this whole year brought heavy losses to the Roman state.
For the Alamanni broke through the frontiers of Germany, being unusually hostile for the following reason: when their envoys had been sent to the headquarters, in order as usual to receive the regular appointed gifts,
And about that time, or not much later, in the Orient Procopius had started a revolution. This and the Alamannic revolt were reported to Valentinian on one and the same day about the first of November as he was on his way to Paris.
Then Valentinian ordered Dagalaifus to go in haste to meet the Alamanni, who after devastating places near the frontier had withdrawn to a distance without the loss of a man. But as to checking the attempt of Procopius before it became ripe, he was distracted by doubt and anxiety, being especially troubled because he did not know whether Valens was alive or whether his death had led Procopius to aspire to the throne.
For Aequitius knew of the matter only from the report of the tribune Antonius, who commanded the soldiers in central Dacia and gave a vague account of the affair from that which he himself had heard; and Aequitius himself had not yet heard anything trustworthy, and so merely reported the circumstance to the emperor in simple words.
