Places in Ireland mentioned in the Sagas, but which formerly could not be traced, have recently been pointed out by the aid of the Irish records. The “Kongespeil” states, for instance, that Saint Diermitius had a church on a small island, “Misdredan” or “Inisdredan,” in the lake “Logherne.” This island is evidently “Inisdreckan” in Lough Erne, where formerly St. Diermitius actually had a church. Subsequent transcribers of the book have clearly enough transformed Inisdreckan into Inisdredan, Misdredan, &c. The same has been the case with the celebrated King Brian Boroimha’s castle, which, by a mistake in copying, is called in the Sagas “Kanntaraborg” or “Kunjáttaborg,” instead of “Kanncaraborg.” Brian Boroimha’s castle, so celebrated in the Irish songs and legends, was called in Irish “Ceann-Caraidh” (pronounced Cancara), and was situated on the river Shannon, not far from Limerick. To the Irish Cancara the Norwegians, therefore, only added the Scandinavian termination “borg.” Again, it is stated in the Sagas that one could sail from Reykjanæs in Iceland to “Jöllduhlaup” in Ireland, in about eight days, or, according to some readings, even in a much shorter time. Formerly this place was sought on Lough Swilley, near Cape Malin, in the north of Ireland. But Jöllduhlaup, which signifies “the course or breaking of the waves,” is merely a translation into Icelandic of the Gaelic name “Corrybracan” (Coire Breacain), whereby the Gaels denote a whirlpool between the little island of Rathlin (or Raghrin) and the north-easternmost part of Ireland (the county of Antrim). That the ancient Icelanders designated this precise spot in Ireland is owing in all probability to the circumstance that the island of Rathlin was in the olden times the chief station in the passage from Ireland to Scotland, and as such the rendezvous for a number of merchants and other travellers. Lastly, Snorre Sturlesön relates that in the beginning of the eleventh century a desperate naval battle was fought between the Orkney jarl Einar and the Irish king “Konofögr,” in Ulfrek’s, or Ulfkel’s, Fiord, on the coast of Ireland. The situation of this fiord, or firth, was entirely unknown until it was lately discovered that in a document issued by the English-Irish king John in the year 1210, the Firth Lough Larne, on the east coast of Ireland, about fourteen miles north of Belfast, was at that time still called “Wulvricheforð,” which agrees most accurately with the Icelandic name “Ulfreksfjörðr.” By a remarkable coincidence, a skeleton was dug up a little while previously just on the shores of Lough Larne, together with a pretty large iron sword, having a short guard and a large triangular pommel at the end of the hilt; the form of which sword (as I shall prove) was not Irish, but pure Scandinavian, like that of the swords used towards the close of heathenism in the North. There is every probability that the skeleton and sword belong to
