Res Gestae

Because of his father’s services Valentinian was favoured from early youth, and being commended also by the addition of his own merits, he was clad in the insignia of imperial majesty at Nicaea. He took as his imperial colleague his brother Valens, to whom he was greatly attached both by the tie of fraternity and by sympathy, a man with an equal amount of excellent and bad qualities, as we shall point out in the proper place.

Valentinian, then, after suffering many annoyances and dangers while he was a private citizen,[*](I.e., not yet emperor (cf. Lucan, v. 666, of Julius Caesar, quoted on p. 520, n. 1).) had no sooner begun to reign than he went to Gaul, to fortify the strongholds and cities lying near the rivers; for these were exposed to the raids of the Alamanni, who were raising their heads higher after learning of the death of the emperor Julian, who was absolutely the only one whom they feared after the death of Constans.

But Valentinian also was rightly dreaded by them, both because he increased the armies with a strong reinforcement and because he so fortified both banks of the Rhine with lofty castles and strongholds, that nowhere should an enemy be able to hurl himself at our territories unobserved.[*](xxviii. 2, 1.)
