When we see these Irish monarchs, however, not only conquering Alban and making settlements there, but extending their conquests over Britain and Gaul, and carrying their arms even to the foot of the Alps, it is difficult to avoid the suspicion that we have here localised as Irish kings some of the Roman emperors connected with the Roman province in Britain, and some of their acts transferred to Ireland, and that this is the true source of many of these fabulous events, so far as there is any foundation for them at all. Thus we find a parallel to the revolt of the Attachtuatha, or servile tribes of Ireland, against the Milesian kings, which was finally suppressed by Tuathal Teachtmhar, in the insurrection of the serf population of Gaul, called the Bagaudæ in the reign of the emperor Diocletian, which was suppressed by his colleague Herculius Maximian. Cairbre Cinncait, who was enabled to seize the throne of Ireland as their leader, and reigned five years, has his counterpart in Carausius, who, by the help of these Bagaudæ, revolted against Maximian, and ruled for seven years in Britain as an independent emperor. Conn of the hundred battles, under whom Ireland became divided into two provinces, may be a shadow of Constantine the Great, in whose time the provinces of Britain were divided; and in Niall of the Nine Hostages, and Dathi the fighter of so many battles, who carried their arms to the foot of the Alps, we may possibly recognise Theodosius and Maximus, the emperors who preceded the termination of the Roman power in Britain, and fought battles in North Britain.
