Another and more important collection was made under the reign of Theodosius II., by public authority. The emperor nominated, in the year 435, a commission of sixteen persons, under the direction of Antiochus, for the purpose of collecting the constitutions from the time of Con stantine the Great ; and three years after wards (a. D. 438), the new code, called Codex Theodosianus, was confirmed by the emperor, and published in the Eastern empire. In the same year (438) the code was sent to Rome to Valentinian III., and confirmed as law for the Western empire. This compilation was formed on the model of those of Gregorianus and Hermogenia nus. It contains sixteen books, divided into titles, in which the separate constitu tions are arranged, according to their subject-matter, in such a way that many of them are subdivided. Some additions, called Novellie, were afterwards made to the collection of Theodosius. The first five books were lost, but some parts of them have been discovered at Milan, by Clossius (Clossii, "fheodos. Codic.
Gentiin. Fragments,' Tfib. 1824); and at Turin, by Peyron Codic. Theodos. Fragments Ined.,' Tur. 1823-24). Carlo Baudik Besme has recently discovered at Turin palimpsests which contain valuable addi tions to, and means of improving the text of the Theodosian Code. The edition of the Theodosian Code by Jac. Gotha fredus, tom. vi. Lugd., 1665, is valuable for the commentary which was also pub lished, together with the text, by Ritter, Leipzig, 1736-54. The last edition is the valuable critical edition of G. Haenel, Bonn, 1837.
In the year 506, Alaric II. caused an abridgment to be made of the Theodosian Code, to which were added excerpts from the codices Gregoriani and Hermogeniani, and of the works of the Roman lawyers Gains and Paulus, for the use of the Ro mans then living in the empire of the Visigoths : the collection is called Bre viarium Alaricianum: The last and most important collection of Roman constitutions was made by the order of Justinian, and is entitled Codex Justinianeus.
