The period of Roman freedom was the period during which the stamp of a distinctive character was impressed on the Roman jurisprudence; and through all the earlier part of it, it was by the Responses of the jurisconsults that the development of the law was mainly carried on. But as we approach the fall of the republic there are signs that the Responses are assuming a form which must have been fatal to their farther expansion. They are becoming systematised and reduced into compendia. Q. Mucius Scævola, the Pontifex, is said to have published a manual of the entire Civil Law, and there are traces in the writings of Cicero of growing disrelish for the old methods, as compared with the more active instruments of legal innovation. Other agencies had in fact by this time been brought to bear on the law. The Edict, or annual proclamation of the Prætor, had risen into credit as the principal engine of law reform, and L. Cornelius Sylla, by causing to be enacted the great group of statutes called the _Leges Corneliæ_, had shown what rapid and speedy improvements can be effected by direct legislation. The final blow to the Responses was dealt by Augustus, who limited to a few leading jurisconsults the right of giving binding opinions on cases submitted to them, a change which, though it brings us nearer the ideas of the modern world, must obviously have altered fundamentally the characteristics of the legal profession and the nature of its influence on Roman law. At a later period another school of jurisconsults arose, the great lights of jurisprudence for all time. But Ulpian and Paulus, Gaius and Papinian, were not authors of Responses. Their works were regular treatises on particular departments of the law, more especially on the Prætor's Edict.
The _Equity_ of the Romans and the Prætorian Edict by which it was worked into their system, will be considered in the next chapter. Of the Statute Law it is only necessary to say that it was scanty during the republic, but became very voluminous under the empire. In the youth and infancy of a nation it is a rare thing for the legislature to be called into action for the general reform of private law. The cry of the people is not for change in the laws, which are usually valued above their real worth, but solely for their pure, complete, and easy administration; and recourse to the legislative body is generally directed to the removal of some great abuse, or the decision of some incurable quarrel between classes and dynasties. There seems in the minds of the Romans to have been some association between the enactment of a large body of statutes and the settlement of society after a great civil commotion. Sylla signalised his reconstitution of the republic by the Leges Corneliæ; Julius Cæsar contemplated vast additions to the Statute Law; Augustus caused to be passed the all-important group of Leges Juliæ; and among later emperors the most active promulgators of constitutions are princes who, like Constantine, have the concerns of the world to readjust. The true period of Roman Statute Law does not begin till the establishment of the empire. The enactments of the emperors, clothed at first in the pretence of popular sanction, but afterwards emanating undisguisedly from the imperial prerogative, extend in increasing massiveness from the consolidation of Augustus's power to the publication of the Code of Justinian. It will be seen that even in the reign of the second emperor a considerable approximation is made to that condition of the law and that mode of administering it with which we are all familiar. A statute law and a limited board of expositors have risen into being; a permanent court of appeal and a collection of approved commentaries will very shortly be added; and thus we are brought close on the ideas of our own day.
