The Irish heroic tales having passed through the hands of Christian redactors, the question occurs whether we must ascribe to them any ethical element that occurs therein. Although it is hard to pronounce with certainty, where they contain no express reference to the Christian faith, it would be rash, and probably a mistake, to reply in the affirmative in all cases. Certain ethical ideas there must have been in pre-Christian Ireland, and the places and the mode in which we find them are often those in which they might most naturally appear. In the instances referred to, there is nothing inconsistent with a system of ethics far more primitive than that to which the ancient Irish might conceivably have attained. Moreover, there is nothing about the passages in question suggestive of an interpolation; they arise quite naturally out of the narrative, and in one striking instance, that of Segda Saerlabrad, are expressly bound up with the pagan idea of human sacrifice in a manner that no Christian writer could or would have invented. Neither does it seem likely that an ecclesiastical writer who should make such interpolations in the interest of the Christian religion would make no mention of that religion in connection with them. The very tales in question show in what a clumsy and perfunctory manner such interpolations were made, when it was found expedient to bring an ancient legend into agreement with Christian doctrine. Instances of this are furnished by the prophecies of Manannán Mac Lír in the Voyage of Bran, and the reference to the Judgment in the Adventures of Connla. The last-named story further contains a prophecy of the coming of the law which shall destroy Druidism and its charms ‘upon the lips of black lying demons.’

As previously mentioned, there exists in these same stories a connection between the Echtra and Imram classes of tales. In several of them the hero departs in his curach in quest of a Wonderland that lies oversea,[125] passing in the course of his voyage through the herds of sea-monsters which beset the heroes of the Imrama, and beholding marvels and visiting enchanted islands entirely similar to those which occur in the latter.

In the Imrama proper we may note in an ascending scale the gradual preponderance of Christian ideas, and the assimilation of the old Irish conception of the Otherworld to a genuine eschatology. Some of them, such as the Voyage of Bran, and Cuchulainn’s quest of the sons of Doel Dermait, relate a purely pagan legend, though the clerical redactors have sought to dissociate them from the paganism which was scarcely forgotten in their day by the interpolation of a Christian prophecy, or the like, as in Christian Rome the statues of the Olympian deities were converted into the effigies of Christian saints by the apposition of a nimbus to their heads. Then come a group written from a Christian point of view, and enforcing a lesson in Christian morals, although the framework of the story and most of the episodes are derived from the older literature:[126] such are the Voyages of Maelduin, of the sons of Ua Corra, and of Snedgus and Mac Ríagla. Finally, there are the purely ecclesiastical Imrama, included in the acts of one or other of the saints, of which class the Voyage of St. Brendan is in every way the most important example.

We have been induced somewhat to anticipate the earliest of the Imrama, and to give the greater part of the description of Manannán’s Elysium contained in the Voyage of Bran, in order to present in a single view the different forms in which the Otherworld was conceived by the ancient Irish. The story goes on to relate how, the maiden’s song ended, the branch leapt back again into her hand, and she vanished; but the glamour was on Bran, and he set forth in his curach across the sea. Here he meets Manannán Mac Lír, traversing the sea in his chariot like a veritable Poseidon.[127] The god accosts Bran, and sings to him a song concerning his Elysian realm beyond the sea. His description adds but little to that contained in the maiden’s song; one touch, however, we may note, by reason of its frequent occurrence in subsequent writings. He speaks of a ‘charming delightful game,’ at which the denizens play over their wine, ‘men and gentle women beneath a bush, without sin, without transgression.’ This passage has been accredited to Christian transcribers; however, the remarks previously offered in relation to such interpolations in general would seem to apply to the present case. The very poetical description of the Tír Tairngire contained in this tale, while thoroughly in accord with the more primitive legends, though amplified and drawn by a more masterly hand, is marked by a refinement of imagination and execution more than sufficient to account for the occurrence of the idea in question, without any air of incongruity with the rest of the description.[128] We may add that it seems most unlikely that a Christian scribe would, if he could, introduce a touch of the kind, when he has not found it necessary, in this and other legends where the old Irish conception of the Otherworld has undergone an euhemerising and Christianising process, to delete the episodes of enchanted dúns and islands where the wayfarer is refreshed with delights akin to those of the Mohammedan Paradise.[129] Manannán’s song in the present tale contains a palpable interpolation of the usual kind, in the form of several stanzas prophetic of the coming of Christ.

Another Imram belongs to the Cuchulainn cycle, and in its original form was probably older than any other story of this class that has come down to us, but it is only preserved in a later redaction. Cuchulainn having overcome in battle the king of the Ui Maine, the king put a spell on him that he should know no peace until he had ascertained why the children of Doel Dermait had left their country. Cuchulainn could find no one to tell him this, and became a prey to unrest. At length he had occasion to fight a duel with the king of Alba’s son, whom he vanquished and would have slain, but that the prince begged his life, which Cuchulainn granted him on condition that he would solve the riddle. This the prince could not do himself, but he promised to take Cuchulainn to those who could. Cuchulainn accepted these terms, and embarked on board the prince’s ship with his charioteer Loeg and his comrade Lugaid. They first came to a fair island, wherein was a dún surrounded by a wall of silver and a stockade of bronze upon it. They received a cordial welcome, but upon propounding their question were directed to another island, where dwelt Achtlann, daughter of Doel Dermait and wife of Condla Coel Corrbacc, a kind of marine Enceladus, who used to lie all across his island, and at every breath he drew would send a great wave along the sea with the wind of it. Achtlann guided them to a third island, where two great giants bore joint rule, Corpre Cundail, a kinsman of Doel Dermait, and Eochaid Glas Corpre. The former challenged Cuchulainn to fight, and, being overcome, treated him hospitably, and told him of Doel Dermait’s children, who were held captive in that island by Eochaid. Next day Cuchulainn attacked Eochaid in his ‘Place of Torture,’ the Glenn; but the giant was so tall that Cuchulainn could only reach him by jumping on to the rim of his shield, from which Eochaid kept blowing him off each time. Cuchulainn, however, by dint of one of those gymnastic feats for which he was famous, leapt into the air over the giant and slew him from above. He then released the captives, who straightway bathed in the giant’s blood, and being thus healed of their tortures and sufferings, were enabled to return to their own country. In this story, which assuredly bears small imprint of Christian influences, we probably have the earliest form of that episode of the release of the captives of some giant or wizard, which recurs in the Graal romances, and is one of the most frequent incidents of the romantic tales of chivalry.[130] Its meaning is clear, the release of the dead from the powers of the lower world, a feat which is no less frequently accomplished by different means, in mediæval stories, by a saint or jongleur, according as the scope of the work is religious or comic.

The earliest of the Christian Imrama that we possess is The Voyage of Maelduin’s Curach, the composition of which Professor Zimmer refers to the eighth century at latest, though it contains interpolations which Mr. Nutt considers to have been made at the end of the tenth century.[131] It relates a voyage undertaken by Maelduin, a young noble of the Eoghanachta, in order to find the murderer of his father who had been slain by a marauder of Leix. The tale is a remarkably fine one of its kind, and its simple and picturesque prose is by no means improved upon by Tennyson’s poem, the subject of which it suggested. It is long, and contains a great variety of incidents, some of which, it is very possible, may not belong to the original Celtic stock, but may be due to classical sources. Certain it is that a great part of them belong to that class of ‘ferlies’ which old writers used to place in terræ incognitæ, and have their analogues in the writings of Herodotus and Aelian, and, Mr. Stokes says, Megasthenes, to whom we may add Lucian and Sinbad. The majority of them, however, are variants, and often developments, of topics common in Irish legend. We must content ourselves with giving a brief summary of those episodes which most illustrate the development of the Otherworld legend in Irish ecclesiastical literature.

As usual, the narrative mainly consists of the visits paid by the wanderer to a number of enchanted islands, which are mostly of the usual Wonderland pattern, though the present description of them contains, in most cases, certain distinctive features of its own. The wanderers are entertained in stately dúns, with walls and palisades of the precious metals or of crystal; they are regaled with magic food; there is the usual Calypso episode, etc. etc. One island is raised above the sea upon a pedestal; in another is a river of fire; one is encompassed with a wall of water; over another a stream rises on one side and descends on the other, forming an arch like a rainbow; upon another is a tall column with a mystical veil depending from it and enshrouding the island,—all of which recall features of the Paradise described in the Fis Adamnáin.

Some of the incidents bear a decidedly infernal significance. On one island the voyagers beheld a horse-race, and heard the shouts of the crowd; both jockeys and spectators were demons. It has been suggested that this incident, for which no parallel exists, so far as I am aware, in earlier narratives, may be of Norse origin; possibly it may be one of those loans from classical literature before referred to, and ecclesiastical influences may have depicted in Stygian colouring the pagan Elysium in which departed heroes continue to ply their wonted sports.[132] At the same time, it is possible that the writer may have dealt in a like manner with the sports of Magh Mell, in Manannán’s Elysium, described in the Imram Bráin. Of course, the question of foreign importation turns upon the other question, whether horse-races, as well as chariot-races, were known in Ireland at the date when the Voyage of Maelduin was written.

On another island they saw a party of demon smiths forging a mass of glowing metal, which one of them threw after the curach, as Polyphemus threw the rock after Odysseus.[133] On another they came to a huge, hideous mill, and the miller, huge and hideous to match, told them that the grist which he cast into his mill was all things that had been begrudged on earth. This demon miller is rather a favourite symbol in Irish legend, and is not confined to professedly religious compositions. It occurs in the story of Mongán in a slightly different form; in the Voyage of the sons of Ua Corra, who saw all manner of precious things cast into the mill, and the miller told them, ‘I cast into the mouth of the mill all things for which grudging has been made, and ’tis the Miller of Hell I am’; and it survived in local tradition as the Muilleann Luprachán (Pixies’ Mill) near Tuam.[134]

There is something weirdly picturesque in this demon miller who casts into his Mill of Vanities, and grinds down there, all the objects of worldly covetise; the conception reminds us rather curiously of the mystical Wheat-sieve in the carnival hymn of the Florentine Piagnoni, Il Trionfo del Vaglio.
