An eminent jurist who lived about A.D. 110-180, author of the Institutionum Commentarii IV., which contain a systematic summary of the Roman law of family relations, of private property, and of actions; and which for generations was a standard educational work on the subject. This work was known, however, to modern scholars only by the fragments preserved in the Pandects, etc., until in 1816 Niebuhr discovered in the Chapter House of Verona a nearly complete MS. of the original work of Gaius, over which works of St. Jerome had been written.
