They were sometimes mad--hysterical or megalomaniac: sometimes reckless and desperate: sometimes, as in the curious case attested of the Roman armies on the Danube, they were men of strong desires and weak imagination ready to die at the end of a short period, if in the meantime they might glut all their senses with unlimited indulgence.[35:1] Still, when all is said, there is nothing that stirs men's imagination like the contemplation of martyrdom, and it is no wonder that the more emotional cults of antiquity vibrate with the worship of this dying Saviour, the Sôsipolis, the Sôtêr, who in so many forms dies with his world or for his world, and rises again as the world rises, triumphant through suffering over Death and the broken _Tabu_. _Tabu_ is at first sight a far more prominent element in the primitive religions than _Mana_, just as misfortune and crime are more highly coloured and striking than prosperity and decent behaviour. To an early Greek tribe the world of possible action was sharply divided between what was Themis and what was Not Themis, between lawful and _tabu_, holy and unholy, correct and forbidden. To do a thing that was not Themis was a sure source of public disaster. Consequently it was of the first necessity in a life full of such perils to find out the exact rules about them. How is that to be managed? Themis is ancient law: it is τὰ πάτρια, the way of our ancestors, the thing that has always been done and is therefore divinely right. In ordinary life, of course, Themis is clear. Every one knows it. But from time to time new emergencies arise, the like of which we have never seen, and they frighten us. We must go to the Gerontes, the Old Men of the Tribe; they will perhaps remember what our fathers did. What they tell us will be _Presbiston_, a word which means indifferently 'oldest' and 'best'--αἰεὶ δὲ νεώτεροι ἀφραδέουσιν, 'Young men are always being foolish'. Of course, if there is a Basileus, a holy King, he by his special power may perhaps know best of all, though he too must take care not to gainsay the Old Men.
