In any case, it may be said, the question of borrowing does not arise within the narrow limits of our inquiry, which is limited to the pre-Homeric period, since all Greek “katharsis” is post-Homeric. The latter dictum is obviously not literally true, as a glance through the Homeric poems will prove. Homer is aware of the necessity of purification by water before making prayer or libation to the gods: Achilles washes his hands and the cups before he pours forth wine and prays to Zeus,[289.1] Telemachos washes his hands in sea-water before he prays to Athena[289.2]; and there is a significant account of the purification of the whole Achaean host after the plague;[289.3] as the later Greeks would have done, the Achaeans throw away into the sea their λύματα, the infected implements of purification, wool or whatever they used, that absorbed the evil from them. But it has been generally observed that Homer does not appear to have been aware of any need for purification from the stain of bloodshed or from the ghostly contagion of death. It is true that Odysseus purifies his hall with fire and sulphur after slaying the suitors, but we are not sure that the act had any further significance than {290} the riddance of the smell of blood from the house. Sulphur is there called κακῶν ἄκος,[290.1] “a remedy against evil things”; but we cannot attach any moral or spiritual sense to κακὰ, nor is Homeric κάθαρσις related, as far as we can see, to any animistic belief. There is one passage where Homer’s silence is valuable and gives positive evidence; Theoklumenos, who has slain a man of his own tribe and fled from his home, in consequence approaches Telemachos when the latter is sacrificing and implores and receives his protection: there is no hint of any feeling that there is a stain upon him, or that he needs purification, or that his presence pollutes the sacrifice.[290.2] All this would have been felt by the later Greek; and in the post-Homeric period we have to reckon with a momentous growth of the idea of impurity and of a complex system of purification, especially in regard to homicide, leading to important developments in the sphere of law and morality which I have tried to trace out on other occasions.[290.3] But Homer may well be regarded as the spokesman of a gifted race, the Achaeans, as we call them, on whom the burden of the doctrine of purification lay lightly, and for whom the ghostly world had comparatively little terror or interest. Besides the Achaeans, however, and their kindred races there was the submerged population of the older culture who enter into the composition of the various Hellenes of history. Therefore the varied development in the post-Homeric period of cathartic ideas may be only a renaissance, a recrudescence of forces that were active enough in the second millennium. {291} Attica may have been the home where the old tradition survived, and cathartic rites such as the Thargelia and the trial of the axe for murder in the
