The Institutes of Justinian is a component of the Corpus Juris Civilis, the sixth-century codification of Roman law ordered by the Byzantine emperor Justinian I. It is largely based upon the Institutes of Gaius, a Roman jurist of the second century A.D. The other parts of the Corpus Juris Civilis are the Digest, the Codex Justinianus, and the Novellae Constitutiones ("New Constitutions" or "Novels"). Justinian's Institutes was one part of his effort to codify Roman law and to reform legal education, of which the Digest also was a part. Whereas the Digest was to be used by advanced law students, Justinian's Institutes was to be a textbook for new students. The Institutes of Justinian is arranged much like Gaius's work, being divided into three books covering "persons," "things,", and "actions." Unlike the Digest, the extracts do not provide inscriptions indicating from whom the original material was taken.
