bank, which was raised upon one part of the ditch, and sloped away into the other. Many inscribed stones have been found on the site of this _castrum_, which originally were built into the wall; one is noticed by Camden, which read: Ↄ. CANDIDI PEDES XX IIII _i.e._, Centuria Candidi, Pedes xxiiii. Another bore the inscription: COHO. I. FRISIN.[20] Ↄ. MASAVONIS. P.XXIII. --which may be translated into, "The century of Masavo of the first cohort of the Frisians [built] 23 feet." The Frisii were inhabitants of Gaul, who were frequently at war with the Romans, but towards the end of the first century, though they were not actually under Roman rule, they had agreed to contribute men for the imperial army; hence their presence in Lancashire. There have been other centurial stones found near the Manchester settlement which are of considerable interest. One was discovered in 1760 on the south side of the Medlock, near Knott Mill; all that remains of the inscription is: .... ** QPOB XVAR ** CHOR. I. RIS. P. ***** The other centurial stone was found in 1796. It measures 15 inches by 11. It had inscribed upon it: COHR. I. FRISIAVO > QVINTIANI € P. XXIII. The translation would be, "The century of Quintianus, of the first cohort of the Frisians, [built] 24 feet." This stone was found near to one of the gateways to the _castrum_. A tile inscribed to "The twentieth legion, valiant and victorious," was found in 1829, and two others, bearing the words (when extended) _Cohortis III. Bracarum_. A small portion of the wall of a building within the _castrum_ is still preserved; a great portion of it consists of fragments of unhewn red sandstone. In 1612, under the roots of an oak-tree, near to the Roman side, was found part of an inscribed altar. It was much mutilated, and had probably been built into a wall after the departure of the Romans. It is 27½ inches in height, 15½ inches in breadth, and nearly 11 inches thick. This altar passed through many hands, and its whereabouts is now unknown, but a copy of the inscription on its face has been preserved. It was dedicated to "Fortune the preserver, Lucius Senecianius Martius, a centurion of the Sixth Legion, (surnamed) the Victorious." This legion was stationed at Eboracum (York), A.D. 120.
