When Justinian ascended the throne, the reformation of the Roman jurisprudence was an arduous but indispensable task. In the space of ten centuries, the infinite variety of laws and legal opinions had filled many thousand volumes, which no fortune could purchase and no capacity could digest. Books could not easily be found; and the judges, poor in the midst of riches, were reduced to the exercise of their illiterate discretion. The subjects of the Greek provinces were ignorant of the language that disposed of their lives and properties; and the barbarous dialect of the Latins was imperfectly studied in the academies of Berytus and Constantinople. As an Illyrian soldier, that idiom was familiar to the infancy of Justinian; his youth had been instructed by the lessons of jurisprudence, and his imperial choice selected the most learned civilians of the East to labour with their sovereign in the work of reformation. The theory of professors was assisted by the practice of advocates and the experience of magistrates; and the whole undertaking was animated by the spirit of Tribonian. This extraordinary man, the object of so much praise and censure, was a native of Side in Pamphilia; and his genius, like that of Bacon, embraced, as his own, all the business and knowledge of the age. In the first year of his reign, Justinian directed the faithful Tribonian, and nine learned associates, to revise the ordinances of his predecessors, as they were contained, since the time of Hadrian, in the Gregorian, Hermogenian, and Theodosian codes; to purge the errors and contradictions, to retrench whatever was obsolete or superfluous, and to select the wise and salutary laws best adapted to the practice of the tribunals and the use of his subjects. The work was accomplished in fourteen months; and the twelve books or tables, which the new decemvirs produced, might be designed to imitate the labours of their Roman predecessors. The new _Code_ of Justinian was honoured with his name, and confirmed by his royal signature; authentic transcripts were multiplied by the pens of notaries and scribes. A more arduous operation was still behind--to extract the spirit of jurisprudence from the decisions and conjectures, the questions and disputes, of the Roman civilians. Seventeen lawyers, with Tribonian at their head, were appointed by the emperor to exercise an absolute jurisdiction over the works of their predecessors. If they had obeyed his commands in ten years, Justinian would have been satisfied with their diligence; and the rapid composition of the _Digest of Pandects_, in three years, will deserve praise or censure, according to the merit of the execution. From the library of Tribonian, they chose forty, the most eminent civilians of former times; two thousand treatises were comprised in an abridgment of fifty books; and it has been carefully recorded that three millions of lines or sentences were reduced, in this abstract, to the moderate number of 150,000.
