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. (M75) 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 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 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)
