Note 116b — Chapter VI · PASSAGE OF TRAETH MAWR AND TRAETH BACHAN, AND OF NEVYN, CARNARVON, AND BANGOR
Reading edition
This ancient city has been recorded by a variety of names. During the time of the Romans it was called Segontium, the site of which is now called Caer Seiont, the fortress on the river Seiont, where the Setantiorum portus, and the Seteia Æstuarium of Ptolemy have also been placed. It is called, by Nennius, Caer Custent, or the city of Constantius; and Matthew of Westminster says, that about the year 1283 the body of Constantius, father of the emperor Constantine, was found there, and honourably desposited in the church by order of Edward I.
