{108} procession round the villages,” as Tacitus informs us,[108.1] “her chariot and garments and her own person were solemnly washed in the waters of a sacred lake, as if the holy divinity had been polluted by her intercourse with men.” It is also possible that the custom still prevalent in the Teutonic populations of Europe, of leaping over the bonfire on midsummer’s eve, is the relic of a ceremony of fire-lustration performed before the beginning of harvest.[108.2] Doubtless also they had the same rules as those prevailing in nearly all communities, whether civilised or uncivilised, concerning the purity of temples; for we have record of an Icelandic law that the “Holy Place of Peace” was not to be defiled by blood or any human uncleanness.[108.3] Still, though other evidence pointing in the same direction might be gathered, it seems clear that the burden of the cathartic ritual did not weigh heavily on the consciences of our fathers when the dawn {109} of their history begins. I am not aware of any indication, for instance, that they regarded formal lustration after bloodshed to be obligatory or desirable. And their comparative freedom in regard to such ceremonies is a fact of great importance with which we must reckon in our estimate of our later spiritual history. We may at the same time believe, on general grounds, that they also had at some remoter epoch passed through a period of bondage to the same ideas and the same formalities that we find so generally prevalent in other kindred and alien races. The more interesting side of the inquiry now presents itself, the question about the influence that these cathartic ideas may have exercised upon religion, morality, and law. We may endeavour, for the sake of systematisation, to maintain this tripartite classification, although we find it becoming more and more illusory the further our investigation travels back to the earlier social life of man.
