It was possibly in this same year 210, at any rate during his stay in Britain, that Severus completed a great and necessary work--the repair of the wall of Hadrian. So grievously had this long barrier suffered at the hands of the barbarians that reconstruction seemed to the soldiers engaged in it like an actual fresh construction. It is only thus that we can explain the language of the careless, inaccurate authors of the _Historia Augusta_, who, forgetful apparently of the fact that they have already assigned the credit of the work to Hadrian, now say of Severus: “The greatest glory of his reign is that he fortified Britain by a wall drawn across the island and ending on both sides with the ocean, for which achievement he received the name of Britannicus”. Attempts have been made to explain the apparent discrepancy between the two accounts by assigning part of the fortification to Hadrian and part to Severus--for instance, the earthen mounds to the former and the stone wall to the latter; but a careful study of the existing remains does not favour these theories. It seems better to admit that the writer was careless and forgetful, and that British affairs and the story of the Roman wall were of infinitely less importance to him than they are now to us, dwellers in Britain. Severus was doomed to discover, like Edward Plantagenet a thousand years later, how deceptive were victories over the Northern mountaineers. Next year (211) the Mæatæ were again up in arms and were joined by the Caledonians. Filled with wrath he ordered his troops again to invade their land, repeating often the lines of Homer:-- Let not one of the race escape the steepness of ruin, None, your avenging hands, not e’en the babe at the bosom. He was preparing himself once more to set forth in his litter in the short dark winter days for the northern moorlands, when sickness attacked him, aided, some men thought, by Caracalla and the physicians, and on February 4, 211, the old man died at Eburacum. He had lived sixty-five years and reigned seventeen, and he was the last Roman emperor of whose doings in our land we have any detailed description. Scarcely had Severus died when his sons, renouncing apparently all thoughts of vengeance on the Caledonians, left the wintry north and returned to the delights of Rome. The hardly suppressed enmity of the brothers now broke out into open flame; and after various ineffectual attempts, always foiled by the younger man’s vigilance, Caracalla’s centurions slew Geta in his mother’s arms. Wheresoever the name of his victim occurred on the monuments, it was erased by order of the murderer. This strange manifestation of posthumous vindictiveness has left traces in our own country (for instance on a monument in the abbey-church of Hexham) as well as on the Arch of Severus in Rome, and in an inscription near the Second Cataract of the Nile.
