I have never yet been able to bring myself to write about the Causeway, which is a geological freak very curious to look at, and quite worth the sixpence you have to pay for admission, since a company enclosed it some years ago. But in Ireland we expect to have our cliff scenery free. The guides there will tell visitors plenty of comic stories about Finn MacCool. But Finn, in authentic Irish legend, is not a comic figure: he is the centre of the Ossianic tales.
That country north of the glens--which stop at Ballycastle, where Glen Shesk and Glen Tow have their meeting--is called the Route, and so keeps alive a memory of a period older than the Ossianic legends. Dal Riada, or Dal Reuda, that is, the "Portion of Reuda", was the name given to a principality established by one Reuda, who about the second century broke off with a body of followers from the kingdom of Ulster, and established rule on both sides of the narrow seas. Reuda was of the Pictish race, probably; and here in the north the Picts held out longest against the invading Milesians, who came (according to modern theories) drilled foot soldiers, to defeat the earlier chariot-fighting warriors. But the Milesians pushed their conquest here also in about the sixth century, and Fergus, an offshoot of the northern Hy-Neill (Sons of Niall), the dominant Milesian house, made a petty kingdom for himself on both shores; and from him the kings of Scotland traced their descent. This prince, Fergus Mac Erc, has left his name on the Irish coast, for Carrickfergus is shown as the rock on which he came to wreck, when sent adrift by tempest in one of his crossings between the two portions of his kingdom.
Shortly after its establishment, this kingship, or chieftainship, lost its Irish character and centred in Scotland. But relations were constant--though by no means constantly friendly--and the Lords of the Isles held Rathlin Island for many centuries. However near the Irish coast this island lies--only divided by some five miles from the base of Fair Head--the sound between it and the mainland is so dangerous, with its racing tides, as to be an effectual barrier; and very often passage may be easier made from the Scotch coast than from the bay of Ballycastle. At all events, the Mac Donnells owned Rathlin when Robert Bruce needed a refuge, and the castle is still there in which the Bruce sheltered for seven years--and in which it was that he watched the spider's patience and drew the moral for his own far-off designs.
