We have seen[220] that in the days of private vengeance and of tribal society, kin-slaying was normally punished by exile, as wergeld was impossible, and kinsmen revolted against the infliction of death. In those days, kin-slaying was normally a matter for the jurisdiction of the clan. In historical times, kin-slaying was punished by death and the confiscation of property—and these penalties can no longer be regarded as in conflict with clan-psychology, since the slayer was prosecuted in a State Court and was executed by State officials. All these facts are therefore quite consistent and they are mutually explanatory. It was the doctrine of pollution and the evolution of civic government which produced so drastic a revolution in the punishment of kin-murder. We can now understand quite clearly the meaning of Plato’s reference to the penalty of kin-slaying: ‘Of a kindred blood defiled,’ he says,[221] ‘there is no other cleansing, and the pollution cannot be washed away until the life of the slayer shall atone for kin-blood by kin-blood and appease and set to rest the anger of all the kindred. It is proper that a person be restrained from such deeds by the fear of such punishments from the gods.’ Euripides also expresses the same sentiment in the _Medea_. The Chorus say[222]: Stern upon mortals the vengeance falleth For kin’s blood spilt: from the earth it calleth, A voice from the gods, and the slayers appalleth, On whose homes it shall light. How then do we suppose that the murder of a husband by his wife, or of a wife by her husband, was punished in Attic law? Such parties were usually not akin by blood. Yet they lived in the same house and they ate at the same table.[223] The penalty in this case was, we think, precisely the same as the penalty for ordinary wilful homicide. The slayer had the option of going into exile for ever if he fled before conviction, or of suffering death at the hands of the public executioner if he did not flee. Hence, perhaps, Euripides[224] is thinking of the historical Attic law when, in the _Orestes_, he makes Tyndareus assert that Orestes should not have slain his mother, but should have put her on trial and have banished her as an exile for ever. We must assume that in the event of exile the property of such slayers was confiscated, though it seems very cruel that children whom murder and vengeance had deprived of both their parents were compelled in addition to forfeit their patrimony.
