"De Exidio et Conquestu Britanniae"
Y ahora combinemos la historia con la mitología británica:
"The first traces of the Arthurian myth belong to the oral tradition of the Celts living in Wales. Unfortunately we have next to no written evidence from this time, the Mabinogion being the only exception. The first written evidence showing a connection to Arthur can be found in the De Exidio et Conquestu Britanniae (c.547) the first of a number of "Histories of the British". Gildas doesn't mention Arthur but he tells us of the battle of Mt. Badon where the British were led by Ambrosius Aurelianus, a leader of Roman descent. At this battle the invading Angles and Saxons were defeated. The next to mention this battle was Bede in his Historia Ecclesiastica Gentis Anglorum (c.731) he dates this battle to have taken place in the 44th year of the invasion of the Angles and Saxons. The next Welshman to give an account of Mt. Badon and the first to mention Arthur as the leader of the British is Nennius in his Historia Britonum (c.9th century). He tells a story of twelve battles that Arthur fought the twelfth being the battle at Mt. Badon. Nennius also tells of Arthur's dog Cabal who left his footprint on a stone which led Arthur collect a pile of stones at this place, Carn Cabal. The legend goes that the imprinted stone if taken away by travelers will be back on the pile the next morning. This is one of many legends connected to Arthur that the modern reader will normally have problems of connecting with the figure of this legendary King."
