Be that as it may, certain it is that the mistletoe, the instrument of Balder's death, has been regularly gathered for the sake of its mystic qualities on Midsummer Eve in Scandinavia, Balder's home.[292] The plant is found commonly growing on pear-trees, oaks, and other trees in thick damp woods throughout the more temperate parts of Sweden.[293] Thus one of the two main incidents of Balder's myth is reproduced in the great midsummer festival of Scandinavia. But the other main incident of the myth, the burning of Balder's body on a pyre, has also its counterpart in the bonfires which still blaze, or blazed till lately, in Denmark, Norway, and Sweden on Midsummer Eve.[294] It does not appear, indeed, that any effigy is burned in these bonfires; but the burning of an effigy is a feature which might easily drop out after its meaning was forgotten. And the name of Balder's balefires (Balder's Bălar), by which these midsummer fires were formerly known in Sweden,[295] puts their connexion with Balder beyond the reach of doubt, and makes it probable that in former times either a living representative or an effigy of Balder was annually burned in them. Midsummer was the season sacred to Balder, and the Swedish poet Tegner, in placing the burning of Balder at midsummer,[296] may very well have followed an [pg 088] old tradition that the summer solstice was the time when the good god came to his untimely end.
Hence the myth of Balder was probably the explanation given of a similar rite.
Thus it has been shewn that the leading incidents of the Balder myth have their counterparts in those fire-festivals of our European peasantry which undoubtedly date from a time long prior to the introduction of Christianity. The pretence of throwing the victim chosen by lot into the Beltane fire,[297] and the similar treatment of the man, the future Green Wolf, at the midsummer bonfire in Normandy,[298] may naturally be interpreted as traces of an older custom of actually burning human beings on these occasions; and the green dress of the Green Wolf, coupled with the leafy envelope of the young fellow who trod out the midsummer fire at Moosheim,[299] seems to hint that the persons who perished at these festivals did so in the character of tree-spirits or deities of vegetation. From all this we may reasonably infer that in the Balder myth on the one hand, and the fire-festivals and custom of gathering mistletoe on the other hand, we have, as it were, the two broken and dissevered halves of an original whole. In other words, we may assume with some degree of probability that the myth of Balder's death was not merely a myth, that is, a description of physical phenomena in imagery borrowed from human life, but that it was at the same time the story which people told to explain why they annually burned a human representative of the god and cut the mistletoe with solemn ceremony. If I am right, the story of Balder's tragic end formed, so to say, the text of the sacred drama which was acted year by year as a magical rite to cause the sun to shine, trees to grow, crops to thrive, and to guard man and beast from the baleful arts of fairies and trolls, of witches and warlocks. The tale belonged, in short, to that class of nature myths which are meant to be supplemented by ritual; here, as so often, myth stood to magic in the relation of theory to practice.
If a human representative of a tree-spirit was burned in the bonfires, what kind of tree did he represent? The oak the principal sacred tree of the Aryans.
But if the victims—the human Balders—who died by fire, whether in spring or at midsummer, were put to death as living embodiments of tree-spirits or deities of vegetation, it would seem that Balder himself must have been a tree-spirit [pg 089] or deity of vegetation. It becomes desirable, therefore, to determine, if we can, the particular kind of tree or trees, of which a personal representative was burned at the fire-festivals. For we may be quite sure that it was not as a representative of vegetation in general that the victim suffered death. The idea of vegetation in general is too abstract to be primitive. Most probably the victim at first represented a particular kind of sacred tree. Now of all European trees none has such claims as the oak to be considered as pre-eminently the sacred tree of the Aryans. Its worship is attested for all the great branches of the Aryan stock in Europe. We have seen that it was not only the sacred tree, but the principal object of worship of both Celts and Lithuanians.[300] The roving Celts appear to have carried their worship of the oak with them even to Asia; for in the heart of Asia Minor the Galatian senate met in a place which bore the pure Celtic name of Drynemetum or “temple of the oak.”[301] Among the Slavs the oak seems to have been the sacred tree of the great god Perun.[302] According to Grimm, the oak ranked first among the holy trees of the Germans. It is certainly known to have been adored by them in the age of heathendom, and traces of its worship have survived in various parts of Germany almost to the present day.[303] Among the ancient Italians the oak was sacred above all other trees.[304] The image of Jupiter on the Capitol at Rome seems to have been originally nothing but a natural oak-tree.[305] At Dodona, perhaps the oldest of all Greek sanctuaries, Zeus was worshipped as immanent in the sacred oak, and the rustling of its leaves in the wind was [pg 090] his voice.[306] If, then, the great god of both Greeks and Romans was represented in some of his oldest shrines under the form of an oak, and if the oak was the principal object of worship of Celts, Germans, and Lithuanians, we may certainly conclude that this tree was venerated by the Aryans in common before the dispersion; and that their primitive home must have lain in a land which was clothed with forests of oak.[307]
Hence the tree represented by the human victim who was burnt at the fire-festivals was probably the oak.
Now, considering the primitive character and remarkable similarity of the fire-festivals observed by all the branches of the Aryan race in Europe, we may infer that these festivals form part of the common stock of religious observances which the various peoples carried with them in their wanderings from their old home. But, if I am right, an essential feature of those primitive fire-festivals was the burning of a man who represented the tree-spirit. In view, then, of the place occupied by the oak in the religion of the Aryans, the presumption is that the tree so represented at the fire-festivals must originally have been the oak. So far as the Celts and Lithuanians are concerned, this conclusion will perhaps hardly be contested. But both for them and for the Germans it is confirmed by a remarkable piece of religious conservatism. The most primitive method known to man of producing fire is by rubbing two pieces of wood against each other till they ignite; and we have seen that this method is still used in Europe for kindling sacred fires such as the need-fire, and that most probably it was formerly resorted to at all the fire-festivals under discussion. Now it is sometimes required that the need-fire, or other sacred fire, should be made by the friction of a particular kind of wood; and when the kind of wood is prescribed, whether among Celts, Germans, or [pg 091] Slavs, that wood appears to be generally the oak.[308] Thus we have seen that amongst the Slavs of Masuren the new fire for the village is made on Midsummer Day by causing a wheel to revolve rapidly round an axle of oak till the axle takes fire.[309] When the perpetual fire which the ancient Slavs used to maintain chanced to go out, it was rekindled by the friction of a piece of oak-wood, which had been previously heated by being struck with a grey (not a red) stone.[310] In Germany and the Highlands of Scotland the need-fire was regularly, and in Russia and among the South Slavs it was sometimes, kindled by the friction of oak-wood;[311] and both in Wales and the Highlands of Scotland the Beltane fires were lighted by similar means.[312] Now, if the sacred fire was regularly kindled by the friction of oak-wood, we may infer that originally the fire was also fed with the same material. In point of fact, it appears that the perpetual fire of Vesta at Rome was fed with oak-wood,[313] and that oak-wood was the fuel consumed in the perpetual fire which burned under the sacred oak at the great Lithuanian sanctuary of Romove.[314] Further, that oak-wood was formerly the fuel burned in the midsummer fires may perhaps be inferred from the custom, said to be still observed by peasants in many mountain districts of Germany, of making [pg 092] up the cottage fire on Midsummer Day with a heavy block of oak-wood. The block is so arranged that it smoulders slowly and is not finally reduced to charcoal till the expiry of a year. Then upon next Midsummer Day the charred embers of the old log are removed to make room for the new one, and are mixed with the seed-corn or scattered about the garden. This is believed to guard the food cooked on the hearth from witchcraft, to preserve the luck of the house, to promote the growth of the crops, and to preserve them from blight and vermin.[315] Thus the custom is almost exactly parallel to that of the Yule-log, which in parts of Germany, France, England, Servia, and other Slavonic lands was commonly of oak-wood.[316] At the Boeotian festival of the Daedala, the analogy of which to the spring and midsummer festivals of modern Europe has been already pointed out, the great feature was the felling and burning of an oak.[317] The general conclusion is, that at those periodic or occasional ceremonies the ancient Aryans both kindled and fed the fire with the sacred oak-wood.[318]
If the human victims burnt at the fire-festival represented the oak, the reason for pulling the mistletoe may have been a belief that the life of the oak was in the mistletoe, and that the tree could not perish either by fire or water so long as the mistletoe remained intact among its boughs.
But if at these solemn rites the fire was regularly made of oak-wood, it follows that any man who was burned in it as a personification of the tree-spirit could have represented no tree but the oak. The sacred oak was thus burned in duplicate; the wood of the tree was consumed in the fire, and along with it was consumed a living man as a personification [pg 093] of the oak-spirit. The conclusion thus drawn for the European Aryans in general is confirmed in its special application to the Scandinavians by the relation in which amongst them the mistletoe appears to have stood to the burning of the victim in the midsummer fire. We have seen that among Scandinavians it has been customary to gather the mistletoe at midsummer. But so far as appears on the face of this custom, there is nothing to connect it with the midsummer fires in which human victims or effigies of them were burned. Even if the fire, as seems probable, was originally always made with oak-wood, why should it have been necessary to pull the mistletoe? The last link between the midsummer customs of gathering the mistletoe and lighting the bonfires is supplied by Balder's myth, which can hardly be disjoined from the customs in question. The myth suggests that a vital connexion may once have been believed to subsist between the mistletoe and the human representative of the oak who was burned in the fire. According to the myth, Balder could be killed by nothing in heaven or earth except the mistletoe; and so long as the mistletoe remained on the oak, he was not only immortal but invulnerable. Now, if we suppose that Balder was the oak, the origin of the myth becomes intelligible. The mistletoe was viewed as the seat of life of the oak, and so long as it was uninjured nothing could kill or even wound the oak. The conception of the mistletoe as the seat of life of the oak would naturally be suggested to primitive people by the observation that while the oak is deciduous, the mistletoe which grows on it is evergreen. In winter the sight of its fresh foliage among the bare branches must have been hailed by the worshippers of the tree as a sign that the divine life which had ceased to animate the branches yet survived in the mistletoe, as the heart of a sleeper still beats when his body is motionless. Hence when the god had to be killed—when the sacred tree had to be burnt—it was necessary to begin by breaking off the mistletoe. For so long as the mistletoe remained intact, the oak (so people might think) was invulnerable; all the blows of their knives and axes would glance harmless from its surface. But once tear from the oak its sacred heart—the mistletoe—and the tree nodded [pg 094] to its fall. And when in later times the spirit of the oak came to be represented by a living man, it was logically necessary to suppose that, like the tree he personated, he could neither be killed nor wounded so long as the mistletoe remained uninjured. The pulling of the mistletoe was thus at once the signal and the cause of his death.
