Geoffrey blended them all: A magical sword called Caledfwlch and a Roman fortress called Caerleon  appeared in his source material, so Geoffrey’s Arthur ruled from Caerleon and wielded Caliburnus, the Latin translation of Caledfwlch.
Geoffrey ih je objedinio. Čarobni mač Caledfwlch i rimska utvrda Caerleon spominju se u njegovim izvorima, pa je Geoffreyjev Arthur vladao iz Caerleona i posjedovao Caliburnus, što je latinski prijevod naziva Caledfwlch.
