found: Oxford companion to law(Corpus iuris civilis: a collective name for Justinian's works on the Roman law [i.e. the recompilation of Roman law made by Tribonianus and 17 jurists at the mandate of Justinian]; the name was probably first applied in 1583 to distinguish the texts from the Corpus iuris canonici; the traditional medieval arrangement is in 5 v.: 1st, Digestum vetus (books 1-24.2); 2nd, Infortiatum (books 24.3-38); 3rd, Digestum novum (books 39-50); 4th, Codex (books 1-9 out of the 12 books comprising the Codex); 5th, Volumen parvum, containing Institutiones, Novels (in the form of the Authenticum), the remaining 3 books of the Codex (books 10-12: the Tres libri), the Libri feudorum, and some imperial statutes; the standard modern ed. is the Krueger-Mommsen ed. [it, however, does not reflect this traditional arrangement, but regroups the material in its original form: Institutions, Digest, Codex, Novels])
