To Jupiter, the greatest and best, And the Deities Of Augustus; the first cohort of the Tungri, A milliary one,[32] commanded by Quintus Verius Superstis, Prefect. The correspondence between the Notitia and the sculptures derived from this station, is again too striking to admit a doubt, that the Housesteads of the modern shepherd is the BORCOVICUS of the Roman hosts. [Sidenote: THE FATE OF LETTERED STONES.] In this way, the ancient designations of the stations from SEGEDUNUM, Wall’s-end, to AMBOGLANNA, Birdoswald, have been accurately ascertained; but no stony memorial of the past has arisen to confirm the Notitia account of the stations westward of this point. The peculiarly fertile nature of the soil between the river Irthing and the Solway has been inimical to the preservation of the Wall and its antiquities. The wants of a numerous population rendered stones of every kind valuable; and in an ignorant age, when anything in the shape of a letter was regarded as a thing of evil omen, those most precious to the historian were the first to be sacrificed.[33] [Sidenote: THE STATIONS WEST OF AMBOGLANNA.]Since the accuracy of the Notitia has been confirmed in so many instances, it is but fair to conclude, that it may be safely taken as a guide in fixing the Roman designations of the remaining stations along the line. Cambeck Fort is the station next to Birdoswald; the Notitia places PETRIANA next in order to AMBOGLANNA, which has been ascertained to be Birdoswald—doubtless, according to this reasoning, Cambeck Fort is the ancient PETRIANA. In this way, could it be certainly ascertained which were the stations _per lineam valli_, each station might have its Roman name restored, though not a syllable of the ancient designation be retained in the modern cognomen. We should have but to read over the roll-call, and let each camp in succession answer to its name. Unhappily, there is some doubt as to which are the stations along the line of the Wall. Horsley conceives that Watch Cross is the station next in order to Cambeck Fort, and, accordingly, calls it ABALLABA; Stanwix, Burgh, Drumburgh, and Bowness, he successively denominates, after the Notitia, CONGAVATA, AXELODUNUM, GABROSENTIS, and TUNNOCELUM. Subsequent inquirers, and, in particular, the Rev. John Hodgson, have seen reason to suspect that Watch Cross was not a station _per lineam valli_. It probably was destitute of stone walls, and was surrounded only by a rampart of earth.[34] It seems to have been a mere _castra æstiva_—a summer encampment, and consequently, was not entitled to rank with those strongholds that were intended to withstand all foes at all seasons. Should Watch Cross be laid aside, the whole of Horsley’s
