codex gregorianus

CODEX GREGORIA´NUSa collection of imperial Roman constitutions or enactments made by one Gregorianus, of whom nothing else is known; its date is not earlier than A.D. 295, as it contained an exemplum edicti Diocletiani et Maximiani of that year (Coll. leg. Mos. et Rom. 6.4). It comprised enactments of the emperors between Septimius Severus (A.D. 195) and Diocletian and Maximian (A.D. 285-305), and possibly even some as far back as Hadrian (A.D. 117-138). It was divided into Books, at least thirty in number (Fragm. Vat. §§ 266 a, 272, 285-8), and the Books into Titles and Rubrics, the topics being arranged after the order of the perpetual Edict of Salvius Julianus.
