It may be thought that the difference which I have asserted to exist between the ancient and modern view of penal law has only a verbal existence. The community, it may be said, besides interposing to punish crimes legislatively, has from the earliest times interfered by its tribunals to compel the wrong-doer to compound for his wrong, and, if it does this, it must always have supposed that in some way it was injured through his offence. But, however rigorous this inference may seem to us now-a-days, it is very doubtful whether it was actually drawn by the men of primitive antiquity. How little the notion of injury to the community had to do with the earliest interferences of the State _through its tribunals_, is shown by the curious circumstances that in the original administration of justice, the proceedings were a close imitation of the series of acts which were likely to be gone through in private life by persons who were disputing, but who afterwards suffered their quarrel to be appeased. The magistrate carefully simulated the demeanour of a private arbitrator casually called in. In order to show that this statement is not a mere fanciful conceit, I will produce the evidence on which it rests. Very far the most ancient judicial proceeding known to us is the Legis Actio Sacramenti of the Romans, out of which all the later Roman Law of Actions may be proved to have grown. Gaius carefully describes its ceremonial. Unmeaning and grotesque as it appears at first sight, a little attention enables us to decipher and interpret it.
