Thus much of Justinian as builder: space fails to enumerate a tithe of his works. Of his great legal achievement we must speak at even shorter length. The Roman law, as he received it from his predecessors was an enormous mass of precedents and decisions, in which the original basis was overlaid with the various and sometimes contradictory rescripts of five centuries of emperors. Several of his predecessors, and most especially Theodosius II., had endeavoured to codify the chaotic mass and reduce it to order. But no one of them had produced a code which sufficed to bring the law of the day into full accord with the spirit of the times. It was no mean work to bring the ancient legislation of Rome, from the days of the Twelve Tables down to the days of Justinian, into strict and logical connection with the new Christian ideas which had worked their way into predominance since the days of Constantine. Much of the old law was hopelessly obsolete, owing to the change in moral ideas which Christianity had introduced, but it is still astonishing to see how much of the old forms of the times of the early empire survived into the sixth century. Justinian employed a commission, headed by the clever but unpopular lawyer Tribonian, to draw up his new code. The work was done for ever and a day, and his “Institutes” and “Pandects” were the last revision of the Old Roman laws, and the starting-point of all systematic legal study in Europe, when, six hundred years later, the need for something more than customary folk-right began to make itself felt, as mediæval civilization evolved itself out of the chaos of the dark ages. If the Roman Empire had flourished in the century after Justinian as in that which preceded him, other revisers of the laws might have produced compilations that would have made the “Institutes” seem out of date. But, as a matter of fact, decay and chaos followed after Justinian, and succeeding emperors had neither the need nor the inclination to do his work over again. Hence it came to pass that his name is for ever associated with the last great revision of Roman law, and that he himself went down to posterity as the greatest of legislators, destined to be enthroned by Dante in one of the starry thrones of his “Paradise,” and to be worshipped as the father of law by all the legists of the Renaissance.
