As a proof of Christians having visited the Island, a medal was found in one of the Druid Mounds in Anglesey bearing the inscription, “This is Jesus Christ the Mediator,” and as the Romans had routed the Druids, this medal must have been there before the demolishing of the mound by Suetonius Paulinus, thus verifying in part the words of Tertullian an age later, who relates the sudden progress of the Christian Faith, which anticipated the Roman sword in the celerity of its conquests. The first school of “Christian learning” to supply the province with clergy was apparently founded at Bangor, Anno Domini 182, and it is supposed that according to the usual plan of organization there were seven bishops under an archbishop in this province of Britain. Some of these were bishops of endowed sees, others were consecrated “Sine Titulo.” The clergy in general appear to have lived with their bishops, forming collegiate bodies, and they were sent out by their superiors into various districts allotted to them as occasion required. It does not appear that they had any settled parishes in Mona for many years after this period nor were there many churches; but they “assembled the people together to hear the Word of God preached in some convenient place, either at oratories or at the manor-houses of their respective Lords and Masters, who probably had their own chapels for sacred use and service. Most of these churches and chapels were dedicated to such early Christian names as St. Mary, St. Peter, St. Michael, &c.” (see “Mona Antiqua.”) After the departure of the Romans in A.D. 390 the Picts tried to regain their former possessions, and the country was sorely ravaged by them until there stood up two families of eminent rank who laid claim to the British Sceptre. The one was headed by Octavius, grandson of the Duke of Cornwall; the other was descended from Cynetha Weledig, and nearly related to Constantine the Great. For many years struggles continued between these rival Princes; but at length the descendant of the Cornwall family gave up the contest and retired to the Duchy of Cornwall. Cynetha’s descendants having routed the Picts who had invaded Mona, made head also against the Saxons. For a long time they withstood them victoriously, having secured all the ancient “Brittannia Secunda” (now called Wales) from the ravages of these invaders, and to them the poor Britons, and more especially the clergy, fled for protection. It is difficult to trace the exact date of the foundation of the church of St. Cybi at Holyhead, but it appears to have been founded by Cybi the son of Selyt, or Solomon, about 550 A.D. He afterwards, according to tradition, became Bishop of Anglesey.
