Since Greece, unlike Israel, was a conglomeration of local civic groups, and as tribal custom had accepted exile in default of wergeld and prescribed different periods of exile according to varying degrees of guilt, therefore, when the issue was knit between the new Semitic doctrine of ‘pollution’ and the ancient tribal laws, the resultant compromise produced a new law which decreed perpetual exile for all cases of wilful homicide, including, we believe, originally, even kin-slaying. The law of historical times which condemned the kin-slayer inevitably to death was not, we have reason to believe, a product of the Asiatic-Greek compromise. Like the law which decreed the confiscation of a murderer’s property, it is, we think, to be attributed to the evolution of centralised State government. In regard to manslaughter different periods of exile were, no doubt, decreed according to the different degrees of guilt: the despotic doctrine of theocratic Asia had, in this, to respect the long traditions of tribal Greece: accidental and justifiable slaying probably required no civic atonement. Apollo was compelled to admit such slayers to immediate ‘purgation.’ In other cases, ‘purgation’ was accepted when the prescribed atonement had been made. Our account of this compromise in the Greek doctrine of pollution is complicated by the presence of a third factor which had become more and more important as Greek States increased in size and power, and which must be indirectly attributed to the doctrine of ‘pollution,’ namely, the conception of homicide as an insult to the State gods and to the State, not merely to the Sun, or to the Delphian Apollo, or to some still more distant Orphic deity in the underworld. This conception of homicide raises it at once from the position which it held in the system of ‘private vengeance’: the murderer, like the traitor and the man stained with sacrilege, now stands forth, if not as a criminal in the modern sense, at least as a quasi-criminal, a vile being who has jeopardised by his act the prosperity and the destiny of the State. He is henceforth liable to ἄτιμία,—he must be degraded from citizenship: if he waits for the verdict which declares him a State criminal, he must die. If he flees, his property must be confiscated to the State, as was the property of all ‘degraded’ exiles. Retribution to the relatives, which is the basis of tribal wergeld, has vanished into the air, but the murderer cannot now be buried in the tomb of his fathers: he can never frequent the temples of his gods: he cannot even attend the public games of all the Greeks lest the contact of his presence should pollute his fellow citizens or the gods who no longer can tolerate his presence. But, provided he avoids certain areas and festivals, he may live without fear. A law of Dracon[95] declares that to slay such an exile was murder. Thus we see how the old tribal custom which accepted exile as a complete
