"It was in that form that the Roman law became the common law of Europe; and when, four centuries later, other sources came to be added to it, the _Corpus Juris_ of the school of Bologna had been so universally received, and so long established as a basis of practice, that the new discoveries remained in the domain of science, and served only for the theory of the law. For the same reason, the Ante-Justinian law is excluded from practice." After Justinian the old texts were left to moulder as useless though venerable, and they have nearly all disappeared. The Code, the Pandects, and the Institutes were declared to be the only legitimate authority, and alone were admitted to the tribunals or taught in the schools. The rescripts of the early emperors recognized too many popular rights to suit the despotic character of Justinian; and the older jurists, like the Scaevolas, Sulpicius, and Labeo, were distasteful from their sympathy with free institutions. Different opinions have been expressed by the jurisconsults as to the merits of the Justinian collection. By some it is regarded as a vast mass of legal lumber; by others, as a beautiful monument of human labor. After the lapse of so many centuries it is certain that a large portion of it is of no practical utility, since it is not applicable to modern wants. But again, no one doubts that it has exercised a great and good influence on moral and political science, and introduced many enlightened views concerning the administration of justice as well as the nature of civil government, and thus has modified the codes of the Teutonic nations that sprang up on the ruins of the old Roman world. It was used in the Greek empire until the fall of Constantinople. It never entirely lost authority in Italy, although it remained buried for centuries, till the discovery of the Florentine copy of the Pandects at the siege of Amalfi in 1135. Peter Valence, in the eleventh century, made use of it in a law-book which he published. With the rise of the Italian cities, the study of Roman law revived, and Bologna became the seat from which it spread over Europe. In the sixteenth century the science of theoretical law passed from Italy to France, under the auspices of Francis I., when Cujas, or Cujacius, became the great ornament of the school of Bourges and the greatest commentator on Roman law until Dumoulin appeared. Grotius, in Holland, excited the same interest in civil law that Dumoulin did in France, followed by eminent professors in Leyden and the German universities. It was reserved for Pothier, in the middle of the eighteenth century, to reduce the Roman law to systematic order,--one of the most gigantic tasks that ever taxed the industry of man. The recent discoveries, especially that made by Niebuhr of the long-lost work of Gaius, have given a great impulse to the study of Roman law in Germany; and to this impulse no one has contributed so greatly as Savigny of Berlin.
