atonement, (not, as it was amongst Achaean militarists, a mere flight from death,) was respected despite doctrinal innovations, because it had been sanctified by time. Glotz holds[96] that this immunity in foreign states of exiles who were guilty of wilful murder in their home-land was due to occasional treaties of ἀσυλία between Greek States. We shall see that such immunity was more probably derived from Greek extradition law, and such law implies international authorisation. It was precisely because such laws could be made and enforced that Greek homicides required no ‘cities of Refuge.’ Thus, the Greek pollution-doctrine bears on the face of it the stamp of a compromise between tribe and State, between local gods and international religion. But there was a further compromise, which we must also indicate, namely, that which inevitably took place between the ghosts of the slain and the purifying gods, the καθάρσιοι θεοί. We have argued[97] that the chaotic centuries which followed the Achaean domination produced a much more monstrous and bloodthirsty conception of the Erinnyes than that which existed in the Homeric age. We have suggested that the revolt of the clansmen against Apolline innovations which abolished material retribution for homicide may have rendered still more ferocious and implacable the Erinnyes of the slain. Yet when the Greek Apolline doctrine of pollution was finally accepted by Hellenic tribes and States, the Erinnyes, like the Titans, were subdued, and became so mild that they could be identified with the Semnai Theai and called Eumenides! They could live in peace again, as in Homer, with the Olympian gods whom they had learned to loathe.
