sea-weed when they cannot, being then their principal nourishment. Such were the islands of Aran when Enda first landed on those stormy shores, and such they are to this day. III.--PAGAN REMAINS IN THE ISLES OF ARAN. These islands contain, perhaps, the earliest existing remains of pagan architecture in Western Europe. In every part of the three islands one meets with some monument of a great pre-historic people, whose works even in their ruins will outlive the monuments of later and more civilized peoples. We can only refer to them very briefly, but they are too interesting to be passed over altogether in silence. Those who wish for fuller information would do well to consult Lord Dunraven's admirable _Notes on Irish Architecture_.[161] In each of the three islands are found ancient forts or duns, which are traditionally attributed to the Firbolg or Belgic race. After their overthrow by the Tuatha de Danaans in the great battles of North and South Moytury, it is said that the survivors fled for refuge to the remotest shores and islands of the western coast, and there built on almost inaccessible sites those wondrous forts, whose ruins are still to be seen on the islands and sea-washed promontories from Tory Island to Valentia. It is said that many of this subjugated and exiled race returned from their wanderings about the first century before the Christian era; that they were kindly received by Meave and Aillil, then rulers of the western province; and that they received from them a grant of Connemara, the Isles of Aran, and other uncultivated districts, in which they strongly entrenched themselves against any possibility of future attack. Not without cause did they take these precautionary measures, for it is recorded that Conall Cearnach, and other heroes of Ulster, sought to dislodge them from their desolate homes on those remotest shores. It is highly probable that it was at this period the Firbolgic tribes sought to protect themselves by raising those wondrous stone forts that still excite the admiration of every traveller. Such is the Bardic narrative, and it furnishes a more satisfactory explanation of those ancient stone fortresses along the western coast than any other that has yet been devised. According to another tradition it was not the heroes of the North, but the Dalcais of Thomond, who sought to expel the wanderers from their island homes: and then the Clann Umoir built in self-defence those marvellous fortresses whose remains still excite our admiration, as a further protection against their foes. There are remains of seven forts in the three islands--the first is Dun Ængusa, the Fort of Ængus.
