From the second of these tales we learn that about this time Cathbad, a Druid of the Picts of Ulster, has three daughters. The eldest, Dectcum, was the mother of the celebrated champion Cuchullin; the second, Albe, was the mother of Naisi, Ainle, and Ardan, the three sons of Uisneach; and the third, Finncaemh, was the mother of Conall Cearnach. These champions were all trained in a military school at Sgathaig in the island of Skye, kept by Aife and her father Scathaidh, and by Aife Cuchullin had a son, Connlaoch, whose history forms one of the Fenian tales. The place called Sgathaig can be still identified. On the west side of the parish of Slate in Skye, on an isolated rock overhanging the arm of the sea termed Loch Eishart, are the remains of an old castle now termed Dunscaich; and below it, at a little distance from the shore, is a small island on which is still to be seen one of those ancient vitrified forts which are so closely connected with these Fenian tales. It is likewise called Dunsgathaig or Dunscaich, and was no doubt the site of Aife’s supposed school. Looking across this arm of the sea, the magnificent and most picturesque range of the Coolins form the principal feature in the landscape, and hence the three sons of Uisneach, supposed to have been trained to the use of arms here, are termed in the tale ‘The Three Falcons of Sleibhe Cuillinn,’ that is, of the Coolin hills, now improperly termed Cuchullin hills.[145] On their return to Ulster, Naisi, the eldest, falls in love with a fair girl Deirdri, who had been reared in a tower by Conchubhar, king of Ulster, with the view of making her his wife. Naisi carries her off, and, accompanied by his two brothers and one hundred and fifty warriors, goes to Alban, where they settled in a wild therein, and obtained maintenance of quarterage, that is, an appanage or land of maintenance to be held for service from the king of that country. The sons of Uisneach are said in the tale to have defended by the might of their hands a district and a half of Alban, and are called ‘the Three Dragons of Dunmonadh,’ which seems to have been the residence of the kings, as it afterwards was of the Scottish kings of Dalriada, and may be identified as the isolated hill in the Crinan Moss on the banks of the river Add, the top of which bears the remains of a strong fortification, and which was also called Dunadd. In another poem Naisi is said to have visited the daughter of the Lord of Duntreoin on his return from the north of Invernois or Inverness, and this is Duntroon, an old castle on the north side of Loch Crinan.
