Here is a passage from the "Dinnseanchus" at page 162 of the "Book of Leinster." Treating of Knock Aillinn, these lines occur:-- "Faichthi ruamand ruamnad rinn Co failgib flatha for Fhind." Irish scholars may interpret these lines as they like, but it would seem that the last word is a proper name, and that it relates to Finn. But whether Finn lived in Knock Aillinn or in Allen, or whether he lived in both places off and on, is a matter of minor importance. The real wonder about him is the way he impressed himself not only on the age in which he lived but on every age since then. No other man in any age or country seems to have so fastened himself in the memories of the people of his own race and lineage. It may be safely said that neither Julius Caesar nor Charlemagne have impressed themselves on popular imagination so much as Finn and those associated with him have. Those who have not studied the Celtic folk-lore of Ireland and Scotland can form but an incomplete idea of the overwhelming immensity of the folk-lore about Finn and his cycle that exists even yet. But with the decay of Gaelic speech it is rapidly fading away. It is hardly too much to say that when Gaelic was the language of the fireside all through Ireland and a large part of Scotland, and that is only a few centuries ago, there was not a parish from Kerry to Caithness in which dozens of different stories about Finn and his contemporaries did not exist; and it is equally safe to say that not the tenth, probably not the twentieth, part of them was ever committed to writing. Finn, Ossian, and Caoilte were the _dramatis personæ_ of the most extensive, if not the choicest, popular, unwritten folk-lore that probably ever existed in any country. But one of the strangest things connected with the cycle of Finn and Ossian is that its folk-lore hardly appears at all in really ancient Gaelic literature. The Gaelic scribes of the tenth, eleventh, and twelfth centuries took but little notice of it; it was to the events of the Cuchulainn cycle that they gave almost their entire attention. In the "Book of Leinster," the greatest repertory of Gaelic literature that exists in one volume, there is only one story that can be called an Ossianic or Finnian one, while nearly half the book is taken up with tracts and stories relating to the cycle of Cuchulainn, which was nearly three centuries earlier than that of Ossian and Finn. But the Cuchulainn cycle, from whatever cause will probably be never known, seems to have entirely failed to take hold of the popular imagination. Folk-lore relating to the Cuchulainn cycle is rare. There are a few in which Cuchulainn is mentioned, and M'Pherson in his Ossian mixes the Ossianic and Cuchulainn cycles together, although they were three centuries apart. Of all the prominent names belonging to the Cuchulainn cycle, Queen Medb or Meave was one of the most prominent, but not a single
