Primarily the person thus accursed became liable to the divine penal judgment, not to human caprice; and the pious popular faith, on which that curse was based, must have had power even over natures frivolous and wicked.

But the banning was not confined to this; the king was in reality entitled and bound to carry the ban into execution, and, after the fact, on which the law set its curse, had been according to his conscientious conviction established, to slay the person under ban, as it were, as a victim offered up to the injured deity (-supplicium-), and thus to purify the community from the crime of the individual.

If the crime was of a minor nature, for the slaying of the guilty there was substituted a ransom through the presenting of a sacrificial victim or of similar gifts.

Thus the whole criminal law rested as to its ultimate basis on the religious idea of expiation.
