Gildas, who obtained from after ages the surname of “the Wise,” seems to have been a native of Scottish Strathclyde and was born early in the sixth century; he became a monk and at the age of forty-four wrote what Bede truly calls “a tearful discourse concerning the ruin of Britain”. His object in this discourse was to rebuke the ungodliness of his countrymen and to remind them of the tokens of the Divine wrath which they had already received. He is consequently, for our purpose, a most disappointing writer. We go to him for history and we get a sermon, but we ought in fairness to remember that he never proposed to give us anything else. A large part of his treatise consists of reproductions of the denunciatory passages of the old Hebrew prophets: a more interesting section, but one outside our present purpose, consists of fierce invectives against five wicked, or at least unfriendly, kings of Wales. But there are a few chapters, the only ones that now concern us, in which, in pathetic tones, he tells us something as to the circumstances of the invasion of his country. He harks back to the departure from Britain of the usurper Maximus (383), to which, rather than to the later usurpation of Constantine, he traces her defenceless condition. Stripped of the multitude of brave young men who followed the fortunes of Maximus and never returned, and being themselves ignorant of war, the Britons were “trampled under foot by two savage nations from beyond seas, namely the Scots from the north-west and the Picts from the north”. The description of the invaders as coming from beyond the seas is important. The term “Scots” at this time and for four centuries afterwards means primarily the inhabitants of the north of Ireland, and only secondarily the offshoot from that race who settled in Argyll and the Isles. These invaders, of course, were as Gildas calls them “_transmarini_”: but it is possible that the Picts also, some of whom we know to have been settled in Wigtonshire, came across the shallow land-girdled waters of Solway Firth, instead of attacking the yet undemolished wall, and thus that they too seemed to the dwellers in North-west Britain to be coming from “beyond the seas”.
