For the whole problem is to find out τὰ πάτρια, the ways that our fathers followed. And suppose the Old Men themselves fail us, what must we needs do? Here we come to a famous and peculiar Greek custom, for which I have never seen quoted any exact parallel or any satisfactory explanation. If the Old Men fail us, we must go to those older still, go to our great ancestors, the ἥρωες, the Chthonian people, lying in their sacred tombs, and ask them to help. The word χρᾶν means both 'to lend money' and 'to give an oracle', two ways of helping people in an emergency. Sometimes a tribe might happen to have a real ancestor buried in the neighbourhood; if so, his tomb would be an oracle. More often perhaps, for the memories of savage tribes are very precarious, there would be no well-recorded personal tomb. The oracle would be at some place sacred to the Chthonian people in general, or to some particular personification of them, a Delphi or a cave of Trophônius, a place of Snakes and Earth. You go to the Chthonian folk for guidance because they are themselves the Oldest of the Old Ones, and they know the real custom: they know what is Presbiston, what is Themis. And by an easy extension of this knowledge they are also supposed to know what is. He who knows the law fully to the uttermost also knows what will happen if the law is broken. It is, I think, important to realize that the normal reason for consulting an oracle was not to ask questions of fact. It was that some emergency had arisen in which men simply wanted to know how they ought to behave. The advice they received in this way varied from the virtuous to the abominable, as the religion itself varied. A great mass of oracles can be quoted enjoining the rules of customary morality, justice, honesty, piety, duty to a man's parents, to the old, and to the weak. But of necessity the oracles hated change and strangled the progress of knowledge. Also, like most manifestations of early religion, they throve upon human terror: the more blind the terror the stronger became their hold. In such an atmosphere the lowest and most beastlike elements of humanity tended to come to the front; and religion no doubt as a rule joined with them in drowning the voice of criticism and of civilization, that is, of reason and of mercy. When really frightened the oracle generally fell back on some remedy full of pain and blood. The medieval plan of burning heretics alive had not yet been invented. But the history of uncivilized man, if it were written, would provide a vast list of victims, all of them innocent, who died or suffered to expiate some portent or _monstrum_--some reported τέρας--with which they had nothing whatever to do, which was in no way altered by their suffering, which probably never really happened at all, and if it did was of no consequence. The sins of the modern world in dealing with heretics and witches have perhaps been more gigantic than those of
