For the sake of clearness we will summarise our own conclusions in advance. We believe that ‘private settlement’ was permitted by law or custom—it was not _expressly_ prohibited or permitted by any written code—whenever a ‘release’ from blood-guilt on the part of the victim, before death, was _formally granted_, or, in the absence of a ‘charge,’ could be _tacitly assumed_; but that otherwise ‘private settlement’ was a sin, a religious quasi-criminal offence, and must therefore have been legally invalid, in the sense that the offender was liable to prosecution.[255] This view is not only consistent with, but is in part derived from, our theory of the incompatibility of ‘pollution’ and wergeld. ‘Private settlement’ is not, of course, wergeld in the strict sense, but it has this much in common with it, that it allowed the slayer to remain in his native State for the rest of his life. His presence was not a cause of pollution. We have seen[256] that the Greek religious doctrine of homicide as a ‘pollution’ expresses a compromise between the newly evolved power of synoekised States and the traditions of the tribes, between the ideals of an international autocratic Apollo and the claims of the Erinnyes of the slain who reflected the desires of the dead and of their relatives. It follows that whenever the laws which resulted from this compromise were observed, whenever the prescribed penalty or atonement was paid, Apollo and the Erinnyes were logically compelled to accept the ‘appeasement’ and to signify by their consent, in certain cases, to the ceremonial of ‘purgation’ that the ‘pollution’ of the criminal was washed away. But it was never forgotten that, in theory, the pollution of the slayer had a twofold source: that the stigma of bloodshed was, so to speak, bicellular, and was expressive of the anger of Apollo, on the one hand, and of the anger of the Erinnyes on the other. It is obvious, therefore, that a ‘release’ on the part of a dying victim precluded any serious anger on the part of the Erinnyes, whereas a victim’s solemn command to his relatives to prosecute his slayer[257] set in motion the entire supernatural vigour of the avenging Erinnyes. Thus in the _Eumenides_ of Aeschylus[258] the Furies tend to go to sleep and to forget until they are goaded into activity by the ghost of the slain Clytaemnestra. Hence it is correct to maintain that in the event of a formal or presumed ‘release’ on the part of a dying victim, the slayer was not in any real sense polluted. In such cases, the slayer may have had to undergo ‘purgation’ of a minor kind, one of these local supplementary ‘purgations’ which were intended to free the citizens from religious scruple.[259] Purgation, we have said, was not symbolical of guilt, but rather of atoned guilt or of innocence. But in such cases the slayer was not really ‘polluted.’ His presence in his homeland did not anger the dead or the gods. But if the dying victim did not formally release his
