We come now to another blank half century in the history of Roman Britain. Save for an obscure hint of the presence of the Emperor Constans, son of Constantine, at some time between 337 and 350, we have scarcely any information as to British affairs from the proclamation of Constantine in 306 to the despatch of the elder Theodosius to Britain in 367. This general, father of the more celebrated emperor of the same name, was sent by the Emperor Valentinian to restore some degree of order in the unhappy island, which had suffered from rapacious governors, from accusations of disloyalty cruelly avenged, and more recently from bloody inroads of the Picts and Scots with whom were now joined a tribe who are called “the most valiant nation of the Attacotti,” but who, if we may believe the extraordinary statement of St. Jerome, were actually addicted to the practice of cannibalism. In the three years of Theodosius’ command, the northern invaders were driven back to their mountains, the inhabitants of “that ancient town which was formerly called Londinium but which (in the fourth century) “more often bore the name Augusta” were relieved from their terrors: a new province, the geographical position of which is not made known to us, was staked out and received the name Valentia, in compliment to the emperor. For the time, but probably not for a long time, the blessings of “the Roman peace” were restored to Britain. The general who had achieved this result was shortly after executed at Carthage, a victim to the cowardly suspicion and jealousy of the Emperor Valens, brother of Valentinian. Soon, however, the whirligig of Time brought about a strange revenge. Valens himself perished in the awful catastrophe of Hadrianople, the battle in which the Visigoths utterly routed a great Roman army, the battle which first brought home to the minds of men the possibility of the collapse of the Roman empire. The nephew of Valens, the young and generous Gratian, looking round for some man who as partner of his throne might avert the menaced ruin, found none more suitable than the son and namesake of the murdered pacifier of Britain, and accordingly, in the year 379, Theodosius (whom historians have surnamed the Great) was hailed as Augustus at Constantinople.
