Thus it appears that human sacrifices of the sort I suppose to have prevailed at Aricia were, as a matter of fact, systematically offered on a large scale by a people whose level of culture was probably not inferior, if indeed it was not distinctly superior, to that occupied by the Italian races at the early period to which the origin of the Arician priesthood must be referred. The positive and indubitable evidence of the prevalence of such sacrifices in one part of the world may reasonably be allowed to strengthen the probability of their prevalence in places for which the evidence is less full and trustworthy. Taken all together, the evidence affords a fair presumption that the custom of killing men whom their worshippers regard as divine has prevailed in many parts of the world. Whether the general explanation which I have offered of that custom is adequate, and whether the rule that the priest of Aricia had to die a violent death is, as I have tried to show, a particular instance of the general custom, are questions which I must now leave to the judgment of the reader. CHAPTER IV—THE GOLDEN BOUGH. “Und grün des Lebens goldner Baum.”—FAUST. § 1.—Between heaven and earth. At the outset of this book two questions were proposed for answer; Why had the priest of Nemi (Aricia) to slay his predecessor? And why, before doing so, had he to pluck the Golden Bough? Of these two questions the first has now been answered. The priest of Nemi, if I am right, embodied in himself the spirit, primarily, of the woods and, secondarily, of vegetable life in general. Hence, according as he was well or ill, the woods, the flowers, and the fields were believed to flourish or fade; and if he were to die of sickness or old age, the plant world, it was supposed, would simultaneously perish. Therefore it was necessary that this priest of the woodlands, this sylvan deity incarnate in a man, should be put to death while he was still in the full bloom of his divine manhood, in order that his sacred life, transmitted in unabated force to his successor, might renew its youth, and thus by successive transmissions through a perpetual line of vigorous incarnations might remain eternally fresh and young, a pledge and security that the buds and blossoms of spring, the verdure of summer woods, and the mellow glories of autumn would never fail. But we have still to ask, What was the Golden Bough? and why had each candidate for the Arician priesthood to pluck it before he could slay the priest? These questions I will now try to answer.
