It is certain that we must not confuse these kings, as did the mediæval chroniclers, with those half-divine kings of Almhuin. The chroniclers, perhaps because they loved tradition too well to cast out utterly much that they dreaded as Christians, and perhaps because popular imagination had begun the mixture, have mixed one with another ingeniously, making Finn the head of a kind of Militia under Cormac MacArt, who is supposed to have reigned at Teamhair in the second century, and making Grania, who travels to enchanted houses under the cloak of Aengus, god of Love, and keeps her troubling beauty longer than did Helen hers, Cormac’s daughter, and giving the stories of the Fianna, although the impossible has thrust its proud finger into them all, a curious air of precise history. It is only when we separate the stories from that mediæval pedantry, as in this book, that we recognise one of the oldest worlds that man has imagined, an older world certainly than we find in the stories of Cuchulain, who lived, according to the chroniclers, about the time of the birth of Christ. They are far better known, and we may be certain of the antiquity of incidents that are known in one form or another to every Gaelic-speaking countryman in Ireland or in the Highlands of Scotland. Sometimes a labourer digging near to a cromlech, or Bed of Diarmuid and Grania as it is called, will tell one a tradition that seems older and more barbaric than any description of their adventures or of themselves in written text or in story that has taken form in the mouths of professed story-tellers. Finn and the Fianna found welcome among the court poets later than did Cuchulain; and one finds memories of Danish invasions and standing armies mixed with the imaginations of hunters and solitary fighters among great woods. One never hears of Cuchulain delighting in the hunt or in woodland things; and one imagines that the story-teller would have thought it unworthy in so great a man, who lived a well-ordered, elaborate life, and had his chariot and his chariot-driver and his barley-fed horses to delight in. If he is in the woods before dawn one is not told that he cannot know the leaves of the hazel from the leaves of the oak; and when Emer laments him no wild creature comes into her thoughts but the cuckoo that cries over cultivated fields. His story must have come out of a time when the wild wood was giving way to pasture and tillage, and men had no longer a reason to consider every cry of the birds or change of the night. Finn, who was always in the woods, whose battles were but hours amid years of hunting, delighted in the ’cackling of ducks from the Lake of the Three Narrows; the scolding talk of the blackbird of Doire an Cairn; the bellowing of the ox from the Valley of the Berries; the whistle of the eagle from the Valley of Victories or from the rough branches of the Ridge of the Stream; the grouse of the heather of Cruachan; the
