Whilst the more intimate Roman rule in South Britain gave there its civilizing institutions, its Latin tongue, its arts, laws, and literature, and in the fourth century Christianity, these results became less emphasized northwards—hardly reaching to the wall of Hadrian. The country between the walls remained in the possession of heathen semi- barbarians, scarcely more civilized or trained in the arts of civil government than were the Celtic tribes of the north. There were no Roman towns, and very few remains of Roman villas have been found, beyond York: remains of roads and camps, of altars and sepulchral monuments are found. To the south of York, Britain was a Roman settlement; north of York it was a military occupation. In spite of its roads, its towns, and its mines, Britain was still, at the close of the Roman rule, a wild, half-reclaimed country; forest and wasteland, marsh and fen occupied the larger portion of its surface. The wolf was still a terror to the shepherd; beavers built their dams in the marshy streams of Holderness. Unarmed, and without any military training, feeling themselves weak and helpless in the presence of the dominant race, the Britons of the province were yet sufficiently patriotic, to give negative help at least to the Pictish tribes who were ever making incursions into the district between the walls, and even at times penetrating into the heart of the province. One of these inroads in the reign of Valentinian all but tore Britain from the empire: an able general, Theodosius, found southern Britain itself in the hands of the invaders; but he succeeded in driving them back to their mountains, winning back for Rome the land as far as the wall of Agricola, and the district between the walls was constituted a fifth British province, named after the Emperor, Valentia. And whilst the Pictish clans were thus making wild dashes over the walls, the sea-board of the province was harrassed by marauders from the sea. Irish pirates called Scots, or “wanderers,” harried the western shores; whilst on the eastern and southern coast, from the Wash to the Isle of Wight, a stretch of coast which came to be called the Saxon Shore, Saxon war-keels were making sudden raids for plunder, and for kidnapping men, women, and children, to be sold into slavery. They also intercepted Roman galleys in the Channel, which were engaged in commerce, or on imperial business. In the year 364, a combined fleet of Saxon vessels for a time held the Channel.
