It seems at present generally received among the learned, that the principality of Wales supplies very few remains of Roman antiquities. Some of the inscriptions collected by Camden have scarcely been admitted as genuine by succeeding antiquaries. Upon considering, however, that the second Augustan legion had indisputably their head-quarters at Caerleon in Monmouthshire; that there were other Roman stations (as Maridunum, Luentium, and Segontium) in the more remote parts of the country; and that the eleventh and twelfth Iter in the Itinerary of Antoninus skirted the North and East sides of it; I was hence persuaded, that the intermediate provinces might afford more traces of the Romans than have hitherto been observed; and a late tour through Wales gave me an opportunity of making some enquiries relative to this subject. Little new may, perhaps, be expected after such distinguished writers as Leland, Camden, and the ingenious author of the Archaeologia. But as the former only proposed an Itinerary through the country; as it does not appear that Camden visited every part himself; and as Lhwyd sometimes depended on the relations of others; sufficient scope yet remains for the researches of the inquisitive. As, therefore, these researches formed one principal object of my tour, I esteem myself obliged to communicate the fruits of them to the judgment of this learned Society; and have endeavoured to merit their indulgence, by confining myself to a mere narration of facts.
