LLANIO, a township, in the parish of LLANDEWY-BREVI, union of TREGARON, lower division of the hundred of PENARTH, county of CARDIGAN, SOUTH WALES, 8 miles (N. E.) from Lampeter; containing 131 inhabitants. It is traversed by the high road between Tregaron and Lampeter, which passes along the Vale of the Teivy, and contains so many remains of Roman antiquity, as leave no doubt of its having once contained a station of that people. The site of the Roman Loventium is placed by antiquaries between the right bank of the Teivy and the road, at a place still called Cae'r Castell, where numerous vestiges of foundations are discernible, and whence the Roman Via Occidentalis, or, as it has subsequently been termed, Sara Helen, branched off in a northerly and a south-westerly direction. Three inscribed stones are still preserved, two of them built in the walls of two cottages, and the third, on which can be traced the words Cohors Secunda Augustce Fecit Quinque Pawls, (affording evidence that a cohort of the second Augustan legion erected a certain portion of the walls,) is used as a seat in the porch of one of them. One of the other stones is placed over the chimney, and is inscribed OVERIONI; and on the third, which is inserted in the wall, near the door of the second cottage, can be decyphered Caii Artii manibus (or memorue) Ennius Primus. Other vestiges of this people have been discovered in the neighbourhood at various times, such as coins, domestic utensils, bricks, &c., and on one occasion a large piece of unwrought lead. There is a Sunday school, in which twenty males and thirty females are instructed by gratuitous teachers to read the Welsh Bible andTestament.
