Another of its great landmarks is the contest which is supposed to have taken place in the second century between Conn Ced Cathach, or of the hundred battles, of the line of Heremon, and Eoghan Mor, called Modha Nuadhat, of the line of Heber, and which led to a division of Ireland into two parts separated from each other by a ridge termed Eisgir Riada, leading from Dublin across the island to Galway, composed of a line of gravel hills which existed long after. The northern half was termed Leth Cuinn or Conn’s half, and the southern Leth Mogha or Mogha’s half. This division is mentioned by the old chronicler Tighernac as having been made in the year 165,[124] and is undoubtedly recognised by Bede when he distinguishes the northern province of the Scots from the nations of the Scots who dwell in the southern parts of Ireland.[125] Cormac, son of Art, and grandson of Conn, is said to have sent a fleet across Magh Rein, or the plain of the sea, in the year 240, so that it was on this occasion that he obtained the sovereignty of Alban.[126] He is said by Tighernac to have obtained the name Ulfata, or ‘the people of Ulster at a distance,’ because he banished the Pictish tribes of Ulster to Manann and Innsigall in the year 254.[127] [Sidenote: The race of Ith in Scotland.] These supposed settlements in Scotland during this mythic period were, however, not entirely confined to the kings of the lines of Heber and Heremon, sons of Milesius, but are also attributed to another line of kings descended from Lughaidh, son of Ith, who was father’s brother of Milesius. We read in an ancient tract that ‘these are the tribes of the Gael that are not of the sons of Miledh, nor of the Tuatha De Danann, nor of the Firbolg, nor yet of the Clann Neimhead, and that widely did this tribe spread throughout Erin and Alban. For it is boasted that Maccon obtained sway over the world, and it is certain that he conquered the west of Europe, without doubt that is Alban and France and Saxon land and the island of Britain. And it is boasted concerning Daire Sirchreachtach that he obtained sway over all the west of Europe; and some of the learned say that he won the whole world. And it is stated that Fathadh Canann obtained the government of the whole world from the rising to the setting sun, and (if it be true) that he took hostages of the streams, the birds, and the languages.’[128] The first of these conquerors of the line of Ith, in point of time, was said to be this Daire Sirchreachtach. He had six sons, all called Lughaidh. The eldest was Lughaidh Laidhe. Another was Lughaidh Mal, ‘who won the world from Breatain Leatha or Armorica to Lochlann or Scandinavia, and from Innsi Orc or the Orkneys to Spain.’ The old tract called the Dinnseanchas, says of Carnn Mail in Ulster, ‘Whence was it named? It is not difficult to tell. It was otherwise called Carnn Luighdheach, from Lughaidh Mal, who was driven from Erinn with a fleet of seven ships; and from Alban he
