a 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.
