At the period when Emania was founded, that is, at the period when according to the learned native annalist Tighearnach, the records of the early Irish cease to be "uncertain," the throne of Ireland was occupied by a High-king called Ugony[1] the Great, and a certain body of saga, much of which is now lost, collected itself around his personality, and attached itself to his two sons, Cobhthach Caol-mBreagh and Leary[2] Lorc, and around Leary Lorc's grandson, Lowry[3] the mariner. It was this Ugony who attempted to substitute a new territorial division of Ireland in place of the five provinces into which it had been divided by the early Milesians. He exacted an oath by all the elements--the usual Pagan oath--from the men of Ireland that they would never oppose his children or his race, and then he divided the island into twenty-five parts, giving one to each of his children. He succeeded in this manner in destroying the ancient division of Ireland into provinces and in perpetuating his own, for several generations, when Eochaidh Féidhleach[4] once more reverted to the ancient system of the five provinces--Ulster, Connacht, Leinster, and the two Munsters. This Eochaidh Féidhleach came to the throne about 140 years before Christ, according to the "Four Masters,"[5] and it was his daughter who is the celebrated heroine Mève,[6] queen of Connacht, who reigned at Rathcroghan in Connacht, and who undertook the great Táin Bo or Cattle Raid into Ulster, that has been celebrated for nigh on 2,000 years in poem and annal among the children of the Gael; and her name introduces us to Conor[7] mac Nessa, king of Ulster, to the palace of Emania, to the Red Branch knights, to the tragedy of Déirdre and all the vivid associations of the Cuchulain cycle. It was thirty-three years before Christ, according to the "Four Masters," that Conairé the Great, High-king of all Ireland, was slain, and he is the central figure of the famous and very ancient saga of the Bruidhean Da Derga.[8] And now we come to the birth of Christ, which is thus recorded by the "Four Masters": "The first year of the age of Christ and the eighth of the reign of Crimhthan Niadhnair."[9] Crimhthan was no doubt one of the marauding Scots who plundered Britain, for it is recorded of him that "it was this Crimhthan who went on the famous expedition beyond the sea from which he brought home several extraordinary and costly treasures, among which were a gilt chariot and a golden chess-board, inlaid with three hundred transparent gems, a tunic of various colours and embroidered with gold, a shield embossed with pure silver," and many other valuables. Curiously enough O'Clery's Book of Invasions contains a poem of seventy-two lines ascribed to this king himself, in which he describes these articles. He was fabled to have been accompanied on this expedition by his "bain-leannán" or fairy sweetheart, one of an interesting race of beings of whom frequent mention is made in Irish legend and saga.
