Ambrosius Aurelianus, the descendant of Roman wearers of the purple, is almost certainly a historical personage, though it is impossible to fix the time and place of his operations. So, too, with a shade less of probability is Arthur, or Artorius, whom we may fairly credit with having stayed for a time the torrent of the Saxon advance by the great victory of the Mons Badonicus won at some time between 500 and 516. In both these British champions, however, we ought probably to see not Cymric kings, but Romano-British generals, wielding a power like that of the Roman _duces_ and _comites_, and perhaps even commanding bodies of men trained in some of the traditions of the Roman legion. Most important, on this view of the case, are the words of Nennius himself: “Arthur fought against the Saxons along with the kings of the Britons, but he himself was _Dux Bellorum_”. The short and business-like entries of the Chronicle as to the successive victories which marked the extension of the West Saxon kingdom seem in the main worthy of belief, though we cannot rely with much confidence on the dates attached to every entry. It does not surprise us to find no record of the Saxon defeat at the Mons Badonicus, nor, as has been said, does such silence lessen the probability of its having actually occurred. Ceawlin, the hero of the West Saxons, is undoubtedly a real figure in history, and we may in the main accept with confidence the history of his battles, especially of his crowning victory at Deorham, which undid the work of Mount Badon, and, by giving the command of the Severn Valley and the Bristol Channel to the Saxons, finally separated “West Wales” from Wales. The domestic strife which disastrously ended his career and hurled him from his throne is pretty clearly hinted at in the Chronicle, and we may be allowed to conjecture that it was the continuance of this internal discord which prevented for a long while the further development of Wessex; which made the rising power of Mercia instead of the West Saxon state the protagonist in the conflict with Wales; and which struck the annals of the latter kingdom in the seventh century with barrenness. When Ceawlin died, in 593, already the great pope who was to reunite Britain to Christian Europe was presiding over the Roman Church, and we may be said now at last to see land, the _terra firma_ of authentic and continuous history.
