To discuss name taboo in all its aspects would lead us more deeply into magic and comparative folk-lore than we have yet gone, and such discussion is unnecessary here. We may therefore briefly state that the root of the matter would seem to be that the name and the dread power named are so closely associated in the very concrete thought of the primitive culture that the one virtually is the other: just as one inevitably calls up the other for the modern thinker, so it is that, in the world of objective fact, for the primitive philosopher the one is equivalent to the other. The primitive man, in short, has projected his subjective associations into reality. As regards euphemisms, the process of development possibly is that first you employ any substitute name, and that secondly you go on to employ such a substitute name as will at the same time be conciliatory. In the latter case, a certain anthropomorphosing of the power behind the taboo would seem to be involved.[206]

Next in prominence comes the food taboo; and to this, also, there are non-Celtic parallels all the world over, now and in ancient times. We may take notice of three very striking modern parallels:—A woman visited her dead brother in Panoi, the Polynesian Otherworld, and ‘he cautioned her to eat nothing there, and she returned’.[207] A Red Man, Ahak-tah, after an apparent death of two days’ duration, revived, and declared that he had been to a beautiful land of tall trees and singing-birds, where he met the spirits of his forefathers and uncle. While there, he felt hunger, and seeing in a bark dish some wild rice, wished to eat of it, but his uncle would allow him none. In telling about this psychical adventure, Ahak-tah said:—‘Had I eaten of the food of spirits, I never should have returned to earth.’[208] Also a New Zealand woman visited the Otherworld in a trance, and her dead father whom she met there ordered her to eat no food in that land, so that she could return to this world to take care of her child.[209]

All such parallels, like their equivalents in Celtic belief, seem to rest on this psychological and physiological conception in the folk-mind. Human food is what keeps life going in a human body; fairy food is what keeps life going in a fairy body; and since what a man eats makes him what he is physically, so eating the food of Fairyland or of the land of the dead will make the eater partake of the bodily nature of the beings it nourishes. Hence when a man or woman has once entered into such relation or communion with the Otherworld of the dead, or of fairies, by eating their food, his or her physical body[210] by a subtle transformation adjusts itself to the new kind of nourishment, and becomes spiritual like a spirit’s or fairy’s body, so that the eater cannot re-enter the world of the living. A study of food taboos confirms this conclusion.[211]

A third prominent taboo, the iron taboo, has been explained by exponents of the Pygmy Theory as pointing to a prehistoric race in Celtic lands who did not know iron familiarly, and hence venerated it so that in time it came to be religiously regarded as very efficacious against spirits and fairies. Undoubtedly there may be much reason in this explanation, which gives some ethnological support to the Pygmy Theory. Apparently, however, it is only a partial explanation of iron taboo in general, because, in many cases, iron in ancient religious rites certainly had magical properties attributed to it, which to us are quite unexplainable from this ethnological point of view;[212] and in Melanesia and in Africa, where iron is venerated now, the same explanation through ethnology seems far-fetched. But at present there seem to be no available data to explain adequately this iron taboo, though we have strong reasons for thinking that the philosophy underlying it is based on mystical conceptions of virtues attributed—reasonably or unreasonably—to various metals and precious stones, and that a careful examination of alchemical sciences would probably arrive at an explanation wholly psychological.

Besides many other miscellaneous taboos noticeable in the evidence, there is a place taboo which is prominent. Thus, if an Irishman cuts a thorn tree growing on a spot sacred to the fairies, or if he violates a fairy preserve of any sort, such as a fairy path, or by accident interferes with a fairy procession, illness and possibly death will come to his cattle or even to himself. In the same way, in Melanesia, violations of sacred spots bring like penalties: ‘A man planted in the bush near Olevuga some coco-nut and almond trees, and not long after died,’ the place being a spirit preserve;[213] and a man in the Lepers’ Island lost his senses, because, as the natives believed, he had unwittingly trodden on ground sacred to Tagaro, and ‘the ghost of the man who lately sacrificed there was angry with him’.[213] In this case the wizards were called in and cured the man by exorcisms,[213] as Irishmen, or their cows, are cured by the exorcisms of ‘fairy-doctors’ when ‘fairy-struck’ for some similar violation. The animistic background of place taboos in the Fairy-Faith is in these cases apparent.

Among Ancient Celts

In the evidence soon to be examined from the recorded Fairy-Faith, we shall find taboos of various kinds often more prominent than in the living Fairy-Faith.[214] So essential are they to the character of much of the literary and mythological matter with which we shall have to deal in the following chapters, that at this point some suggestions ought to be made concerning their correct anthropological interpretation.

Almost every ancient Irish taboo is connected with a king or with a great hero like Cuchulainn; and, in Ireland especially, all such kings and heroes were considered of divine origin, and as direct incarnations, or reincarnations of the Tuatha De Danann, the true Fairies, originally inhabitants of the Otherworld. (See our [chapter vii].) As Dr. Frazer points out to have been the case among non-Celts, with whom the same theory of incarnated divinities has prevailed, royal taboos are to isolate the king from all sources of danger, especially from all magic and witchcraft, and they act in many cases ‘so to say, as electrical insulators’ to preserve him or heroes who are equally divine.[215]

The early Celts recognized an intimate relationship between man and nature: unperceived by man, unseen forces—not dissimilar to what Melanesians call Mana—(looked on as animate and intelligent and frequently individual entities) guided every act of human life. It was the special duty of Druids to act as intermediaries between the world of men and the world of the Tuatha De Danann; and, as old Irish literature indicates clearly, it was through the exercise of powers of divination on the part of Druids that these declared what was taboo or what was unfavourable, and also what it was favourable for the divine king or hero to perform. As long as man kept himself in harmony with this unseen fairy-world in the background of nature, all was well; but as soon as a taboo was broken, disharmony in the relationship—which was focused in a king or hero—was set up; and when, as in the case of Cuchulainn, many taboos were violated, death was inevitable and not even the Tuatha De Danann could intercede.

Breaking of a royal or hero taboo not only affects the violator, but his subjects or followers as well: in some cases the king seems to suffer vicariously for his people. Almost every great Gaelic hero—a god or Great Fairy Being incarnate—is overshadowed with an impending fate, which only the strictest observance of taboo can avoid.[216]
