[48] There was also a mixed Norse and Gaelic population in Galloway (the word is a corruption of _Gall-Gaedhil_, Welsh Galwydel) as well as in the Hebrides (Ir. _Innse Gall._, _i.e._, the “Islands of the Foreigners or Norsemen”) and other parts of Scotland. There is a reference to these Gaill-Gaedhil in the _Four Masters_ (A.D. 1154): “The Cinél Eoghain and Muirchertach, son of Niall, sent persons over the sea to hire the fleets of the Gaill-Gaedhil of Aran, Cantire and the Isle of Man and the borders of Scotland in general, over which Mac Sgelling was in command…” (For other references see Marstrander, _op. cit._, p. 9.) By _Gaddgethlar_ the Norsemen understood “the place… where Scotland and England meet” (cf. _Orkneyinga Saga_, ch. 28). It is also interesting to note that in Norse sources the inhabitants of Galloway are called _Vikinga-Skotar_, a direct translation of Gaill-Gaedhil. O’Flaherty (_Ogygia_, p. 360) thought that the Gaill-Gaedhil mentioned in the Annals of the mid-ninth century came to Ireland from Scotland, but the ancient _Three Fragments of Annals_, which contain the fullest accounts of the Gaill-Gaedhil (pp. 138-141) speak of them as _Scuit_ (_i.e._, an Irish form of the Latin _Scoti_, a word which is always used with reference to the Irish before the tenth century). Moreover, the impression received from reading the _Fragments of Annals_ is that the Annalist had in his mind the Norse-Gaelic population of Ireland, not of Scotland. [49] _Ann. Cambriae_, A.D. 902; (Steenstrup: _Normannerne_, III., pp. 37-41). [50] _Three Fragments of Annals_, p. 230 ff. [51] _Annals of the Four Masters_, A.D. 845, 852; _Annals of Ulster_, A.D. 846. _Three Fragments of Annals_, A.D. 862. [52] _Annals of the Four Masters_, A.D. 848. [53] The plundering of these burial-mounds--“a thing that had never been done before”--made a deep impression on the Irish Annalists; it was thought that the Vikings discovered the existence of the treasure by magic, “through paganism and idol worship” (_War of the Gaedhil with the Gaill_, p. 115). The same source (p. 25) records the plundering of Kerry by Baraid (O.N. Barthr) and Olaf the White’s son “who left not a cave there underground that they did not explore.” Several references to this practice of the Vikings occur also in Icelandic literature. It is interesting to compare the Irish accounts with the following passage from Landnámabók (I., ch. 5): “Leifr (one of the earliest settlers in Iceland) went on a Viking raid to the West. He plundered Ireland and found there a large underground house (Icel. _jarth-hus_). It was dark within until he made his way to a place where he saw a light shining from a sword which a man held in his hand. Leifr slew the man and took the sword and much treasure besides.” [54] _Three Fragments of Annals_, p. 135. [55] _Ib._, p. 137. [56] _Heimskringla: Óláfs Saga Tryggvasonar_, ch. 35.
