If a great battle is to be accounted lost or won, as it affects principles rather than reputations, then Brian lost at Clontarf. The leading ideas of his long and political life were, evidently, centralization and an hereditary monarchy. To beat back foreign invasion, to conciliate and to enlist the Irish-born Danes under his standard, were preliminary steps. For Morrogh, his first-born, and for Morrogh's descendants, he hoped to found an hereditary kinship after the type universally copied throughout Christendom. He was not ignorant of what Alfred had done for England, Harold for Norway, Charlemagne for France, and Otho for Germany; and it was inseparable from his imperial genius to desire to reign in his posterity, long after his own brief term of sway should be for ever ended. A new centre of royal authority should be established on the banks of the great middle river of the island—itself the best bond of union, as it was the best highway of intercourse; the Dalgais dynasty should there flourish for ages, and the descendants of Brian of the Tributes, through after centuries, eclipse the glory of the descendants of Nial of the Hostages. It is idle enough to call the projector of such a change an usurper and a revolutionist. Usurper he clearly was not, since he was elevated to power by the action of the old legitimate electoral principle; revolutionist he was not, because his design was defeated at Clontarf, in the death of his eldest son and grandson. Not often have three generations of Princes of the same family been cut off on the same field; yet at Clontarf it so happened. Hence, when Brian fell, and his heir with him, and his heir's heir, the projected Dalgais dynasty, like the Royal Oak at Adair, was cut down and its very roots destroyed. For a new dynasty to be left suddenly without indisputable heirs is ruinous to its pretensions and partizans. And in this the event of the battle proved destructive to the Celtic Constitution. Not from the Anglo-Norman invasion, but from the day of Clontarf we may date the ruin of the old electoral monarchy. The spell of ancient authority was effectually broken and a new one was to be established. Time, which was indispensable, was not given. No Prince of the blood of Brian succeeded immediately to himself. On Clontarf Morrogh, and Morrogh's heir fell, in the same day and hour. The other sons of Brian had no direct title to the succession, and, naturally enough, the deposed Malachy resumed the rank of monarch, without the consent of Munster, but _with_ the approval of all the Princes, who had witnessed with ill-concealed envy the sudden ascendancy of the sons of Kennedy. While McLaig was lamenting for Brian, by the cascade of Killaloe, the Laureat of Tara, in an elegy over a lord of Breffni, was singing— "Joyful are the race of Conn after Brian's Fall, in the battle of Clontarf."
