Chap. XII. How the Britons, being ravaged by the Scots and Picts, sought succour from the Romans, who coming a second time, built a wall across the island; but when this was broken down at once by the aforesaid enemies, they were reduced to greater distress than before. From that time, the British part of Britain, destitute of armed soldiers, of all military stores, and of the whole flower of its active youth, who had been led away by the rashness of the tyrants never to return, was wholly exposed to rapine, the people being altogether ignorant of the use of weapons. Whereupon they suffered many years from the sudden invasions of two very savage nations from beyond the sea, the Scots from the west, and the Picts from the north. We call these nations from beyond the sea, not on account of their being seated out of Britain, but because they were separated from that part of it which was possessed by the Britons, two broad and long inlets of the sea lying between them, one of which runs into the interior of Britain, from the Eastern Sea, and the other from the Western, though they do not reach so far as to touch one another. The eastern has in the midst of it the city Giudi.(74) On the Western Sea, that is, on its right shore, stands the city of Alcluith,(75) which in their language signifies the Rock Cluith, for it is close by the river of that name. On account of the attacks of these nations, the Britons sent messengers to Rome with letters piteously praying for succour, and promising perpetual subjection, provided that the impending enemy should be driven away. An armed legion was immediately sent them, which, arriving in the island, and engaging the enemy, slew a great multitude of them, drove the rest out of the territories of their allies, and having in the meanwhile delivered them from their worst distress, advised them to build a wall between the two seas across the island, that it might secure them by keeping off the enemy. So they returned home with great triumph. But the islanders building the wall which they had been told to raise, not of stone, since they had no workmen capable of such a work, but of sods, made it of no use. Nevertheless, they carried it for many miles between the two bays or inlets of the sea of which we have spoken;(76) to the end that where the protection of the water was wanting, they might use the rampart to defend their borders from the irruptions of the enemies. Of the work there erected, that is, of a rampart of great breadth and height, there are evident remains to be seen at this day. It begins at about two miles’ distance from the monastery of Aebbercurnig,(77) west of it, at a place called in the Pictish language Peanfahel,(78) but in the English tongue, Penneltun, and running westward, ends near the city of Alcluith.
