the sea," or simply the abode of hostile, supernatural beings. Lochlanners would thus be counterparts of the Fomorians, and the conflicts of the Fians with them would reflect old myths. But with the Norse invasions, the Norsemen became the true Lochlanners, against whom Fionn and his men fight as Charlemagne fought Muhammadans—a sheer impossibility. Professor Zimmer, however, supposes that the Fionn saga took shape during the Norse occupation from the ninth century onwards. Fionn is half Norse, half Irish, and equivalent to Caittil Find, who commanded the apostate Irish in the ninth century, while Oisin and Oscar are the Norse Asvin and Asgeirr. But it is difficult to understand why one who was half a Norseman should become the chosen hero of the Celts in the very age in which Norsemen were their bitter enemies, and why Fionn, if of Norse origin, fights against Lochlanners, i.e. Norsemen. It may also be inquired why the borrowing should have affected the saga only, not the myths of the gods. No other Celtic scholar has given the slightest support to this brilliant but audacious theory. On the other hand, if the saga has Norse affinities, and if it is, in origin, pre-Celtic, these may be sought in an earlier connection of Ireland with Scandinavia in the early Bronze Age. Ireland had a flourishing civilisation then, and exported beautiful gold ornaments to Scandinavia, where they are still found in Bronze Age deposits.455 This flourishing civilisation was overwhelmed by the invasion of the Celtic barbarians. But if the Scandinavians borrowed gold and artistic decorations from Ireland, and if the Fionn saga or part of it was already in existence, why should they not have borrowed some of its incidents, or why, on the other hand, should not some episodes have found their way from the north to Ireland? We should also consider, however, that similar incidents may have been evolved in both countries on similar lines and quite independently.
The various contents of the saga can only be alluded to in the briefest manner. Fionn's birth-story belongs to the well-known "Expulsion and Return" formula, applied to so many heroes of saga and folk-tale, but highly elaborated in his case at the hands of the annalists. Thus his father Cumal, uncle of Conn the Hundred Fighter, 122-157 A.D., wished to wed Muirne, daughter of Conn's chief druid, Tadg. Tadg refused, knowing that through this marriage he would lose his ancestral seat. Cumal seized Muirne and married her, and the king, on Tadg's appeal, sent an army against him. Cumal was slain; Muirne fled to his sister, and gave birth to Demni, afterwards known as Fionn. Perhaps in accordance with old matriarchal usage, Fionn's descent through his mother is emphasised, while he is related to the ancient gods, Tadg being son of Nuada. This at once points to the mythical aspect of the saga. Cumal may be identical with the god Camulos. In a short time, Fionn, now a marauder and an outlaw, appeared at Conn's Court, and that same night slew one of the Tuatha Déa, who came yearly and destroyed the palace. For this he received his rightful heritage—the leadership of the Fians, formerly commanded by Cumal.456 Another incident of Fionn's youth tells how he obtained his "thumb of knowledge." The eating of certain "salmon of knowledge" was believed to give inspiration, an idea perhaps derived from earlier totemistic beliefs. The bard Finnéces, having caught one of the coveted salmon, set his pupil Fionn to cook it, forbidding him to taste it. But as he was turning the fish Fionn burnt his thumb and thrust it into his mouth, thus receiving the gift of inspiration. Hereafter he had only to suck his thumb in order to obtain secret information.457 In another story the inspiration is already in his thumb, as Samson's strength was in his hair, but the power is also partly in his tooth, under which, after ritual preparation, he has to place his thumb and chew it.458
Fionn had many wives and sweethearts, one of them, Saar, being mother of Oisin. Saar was turned into a fawn by a Druid, and fled from Fionn's house. Long after he found a beast-child in the forest and recognised him as his son. He nourished him until his beast nature disappeared, and called him Oisin, "little fawn." Round this birth legend many stories sprang up—a sure sign of its popularity.459 Oisin's fame as a poet far excelled that of Fionn, and he became the ideal bard of the Gaels.
By far the most passionate and tragic story of the saga is that of Diarmaid and Grainne, to whom Fionn was betrothed. Grainne put geasa upon Diarmaid to elope with her, and these he could not break. They fled, and for many days were pursued by Fionn, who at last overtook them, but was forced by the Fians to pardon the beloved hero. Meanwhile Fionn waited for his revenge. Knowing that it was one of Diarmaid's geasa never to hunt a wild boar, he invited him to the chase of the boar of Gulban. Diarmaid slew it, and Fionn then bade him measure its length with his foot. A bristle pierced his heel, and he fell down in agony, beseeching Fionn to bring him water in his hand, for if he did this he would heal him. In spite of repeated appeals, Fionn, after bringing the water, let it drip from his hands. Diarmaid's brave soul passed away, and on Fionn's character this dire blot was fixed for ever.460
Other tales relate how several of the Fians were spirited away to the Land beyond the Seas, how they were rescued, how Diarmaid went to Land under Waves, and how Fionn and his men were entrapped in a Fairy Palace. Of greater importance are those which tell the end of the Fian band. This, according to the annalists, was the result of their exactions and demands. Fionn was told by his wife, a wise woman, never to drink out of a horn, but coming one day thirsty to a well, he forgot this tabu, and so brought the end near. He encountered the sons of Uirgrenn, whom he had slain, and in the fight with them he fell.461 Soon after were fought several battles, culminating in that of Gabhra in which all but a few Fians perished. Among the survivors were Oisin and Caoilte, who lingered on until the coming of S. Patrick. Caoilte remained on earth, but Oisin, whose mother was of the síd folk, went to fairyland for a time, ultimately returning and joining S. Patrick's company.462 But a different version is given in the eighteenth century poem of Michael Comyn, undoubtedly based on popular tales. Oisin met the Queen of Tir na n-Og and went with her to fairyland, where time passed as a dream until one day he stood on a stone against which she had warned him. He saw his native land and was filled with home-sickness. The queen tried to dissuade him, but in vain. Then she gave him a horse, warning him not to set foot on Irish soil. He came to Ireland; and found it all changed. Some puny people were trying in vain to raise a great stone, and begged the huge stranger to help them. He sprang from his horse and flung the stone from its resting-place. But when he turned, his horse was gone, and he had become a decrepit old man. Soon after he met S. Patrick and related the tale to him.
Of most of the tales preserved in twelfth to fifteenth century MSS. it may be said that in essence they come down to us from a remote antiquity, like stars pulsing their clear light out of the hidden depths of space. Many of them exist as folk-tales, often wild and weird in form, while some folk-tales have no literary parallels. Some are Märchen with members of the Fian band as heroes, and of these there are many European parallels. But it is not unlikely that, as in the case of the Cúchulainn cycle, the folk versions may be truer to the original forms of the saga than the rounded and polished literary versions. Whatever the Fians were in origin—gods, mythic heroes, or actual personages—it is probable that a short Heldensage was formed in early times. This slowly expanded, new tales were added, and existing Märchen formulæ were freely made use of by making their heroes the heroes of the saga. Then came the time when many of the tales were written down, while later they were adapted to a scheme of Irish history, the heroes becoming warriors of a definite historic period, or perhaps connected with such warriors. But these heroes belonged to a timeless world, whose margins are "the shore of old romance," and it was as if they, who were not for an age but for all time, scorned to become the puppets of the page of history.
The earliest evidence of the attitude of the ecclesiastical world to these heroes is found in the Agallamh na Senorach, or "Colloquy of the Ancients."463 This may have
