Britannia, Roman name for British Isles
Fishburn and Hughes: "The name, probably of Iberian or Gallic origin, of the ancient Roman province of Britain. Christianity probably did not reach Britain before the middle of the third century.
The Theologians: No mention has been found of a diocese of Britain during the sixth century. Reference to the inversion of crucifixes, though fictitious, may be an oblique allusion to the doctrine of the British lay monk Pelagius who in the fifth century questioned original sin and was charged with heresy. His followers developed his theories, denying that Christ had to die for human redemption or act as an intermediary between man and his salvation.
Guayaquil: La matière de Bretagne, refers to one of the three great cycles of medieval literature, the other two being The Matter of Rome and of France. The legend of King Arthur and the Round Table is the best known of these.
These traditional tales are linked to the legendary history of Brittain." (33)
