The laws and legislation of Justinian throw only an indistinct and vague light on the state of the Greek population. They were drawn entirely from Roman sources, calculated for a Roman state of society, and occupied with Roman forms and institutions. Justinian was so anxious to preserve them in all their purity that he adopted two measures to secure them from alteration. The copyists were commanded to refrain from any abridgment, and the commentators were ordered to follow the literal sense of the laws. All schools of law were likewise forbidden, except those of Constantinople, Rome, and Berytus, a regulation which must have been adopted to guard the Roman law from being corrupted by falling into the hands of Greek teachers, and becoming confounded with the customary law of the various Greek provinces. This restriction, and the importance attached to it by the emperor, prove that the Roman law was now the universal rule of conduct in the empire. Justinian took every measure which prudence could dictate to secure the best and purest legal instruction and administration for the Roman tribunals; but only a small number of students could study in the licensed schools, and Rome, one of these schools, was, at the time of the publication of the law, in the hands of the Goths. It is therefore not surprising that a rapid decline in the knowledge of Roman law commenced very shortly after the promulgation of Justinian’s legislation. Justinian’s laws were soon translated into Greek without the emperor’s requiring that these paraphrases should be literal; and Greek commentaries of an explanatory nature were published. His novels were subsequently published in Greek when the case required it; but it is evident that any remains of Greek laws and customs were rapidly yielding to the superior system of Roman legislation, perfected as this was by the judicious labours of Justinian’s councillors. Some modifications were made in the jurisdiction of the judges and municipal magistrates at this time; and we must admit the testimony of Procopius as a proof that Justinian sold judicial offices, though the vagueness of the accusation does not afford us the means of ascertaining under what pretext the change in the earlier system was adopted. It is perhaps impossible to determine what share of authority the Greek municipal magistrates retained in the administration of justice and police, after the reforms effected by Justinian in their financial affairs, and the seizure of a large part of their local revenues. The existence of Greek corporations in Italy shows that they possessed an acknowledged existence in the Roman Empire.[b] BURY’S ESTIMATE OF JUSTINIAN
