“ The ruins of Caerleon attracted notice in the 12th and following centuries, and gave plain cause for legend-making. There is better, but still slender, reason for the belief that it was here, and not at Chester, that five kings of the Cymry rowed Edgar in a barge as a sign of his sovereignty (A.D. 973) . The name Caerleon seems to be derived from the Latin Castra legionum, but it is not peculiar to Caerleon-on-Usk, being often used of Chester and occasionally of Leicester and one or two other places. ”
