The city is connected with the romance of King Arthur and the Knights of the Round Table. It is said that hither Arthur came at Pentecost to be crowned, and that here he often took council with Dubric, or Dubritius, "the high saint." The keep of a castle is mentioned in Domesday Book, the ruins of which, now limited to a solitary bastion on the river's side, were very extensive, even in Leland's time (1506-1552). Caerleon was a place of great ecclesiastical importance and the seat of an archbishopric. It is noticeable as the place of martyrdom, according to Giraldus Cambrensis, of two saints, Aaron and Julius. Their bodies were buried in the city, each afterwards having a church dedicated to him. There is good reason for regarding these as historical personages, but as Caerleon-upon-Dee was also called "the City of the Legions," there is some doubt whether their martyrdom occurred at the former, now called Chester, or at the latter, which still retains its British name. Around the church of S. Cadoc there are abundant remains to show the important centre Caerleon-upon-Usk constituted in Roman times. There is a tradition that its bishop was one of three who attended the Council held at Arles, in 314, to discuss the validity of ecclesiastical orders conferred by such bishops as in time of persecution had delivered up to be burnt their sacred writings. CAERWENT.--This place is on the Chepstow side of Caerleon, near Severn Tunnel Junction. It was a military station, and important discoveries of Roman remains have been made here. CAISTOR CASTLE, or VENTA.--4-1/2 miles from Yarmouth. Caistor Village is 3 miles distant. This place occupies the site of a Roman camp, which, in conjunction with Burgh Castle, guarded this part of the coast. No remains of the camp now exist, but Roman urns, pottery, and coins have been found in and near the village. A field west of the church, styled "East Bloody Furlong" has been fixed upon as the site of the Castrum. CANTERBURY.--Cant-wara-byrig--the burgh of the men of the headland. (Hence, Archepiscopus Cantuariensis). Before the invasion of Caesar, a tribe of the Belgae from Gaul had taken possession of a large portion of South Britain, including Kent. The principal Roman road was the Watling Street, between Dover and London, which followed much the same course as the modern highway. This road was joined at Canterbury by two others, proceeding respectively from Lympne and Reculver. Two other important Roman stations may be distinguished, Durolevum and Vagniacae, the one probably by Faversham, the other by Springhead, near Gravesend. The important position of modern Canterbury is affirmed by the fact that no fewer than 16 roads and railway routes now converge upon the city. So, too, in the olden time, it was a great nerve-centre, and the mid-point of the important Roman fortresses of Dover, Richborough, Reculver, and Lympne.
