His works include
Ad Sabinum, a commentary on the
ius civile, in over 50 books;
Ad edictum, a commentary on the
Edict, in 83 books; collections of opinions, responses and disputations; books of rules and institutions; treatises on the functions of the different magistrates — one of them, the
De officio proconsulis libri x., being a comprehensive exposition of the criminal law; monographs on various statutes, on testamentary trusts, and a variety of other works. His writings altogether have supplied to
Justinian's
Digest about a third of its contents, and his commentary on the
Edict alone about a fifth. As an author, he is characterized by doctrinal exposition of a high order, judiciousness of criticism, and lucidity of arrangement, style, and language.
