Roman law

Property, the law of the Roman people, the populous Romans, of which the oldest monument, only fragmentarily preserved, is the law of the Twelve Tables of about 450 BC.  The Roman law developed by statute, the edicts of magistrates, especially the praetor and by decisions and expositions of lawyers into a vast body of law, revised and summarized by the legislation of the Emperor Justinian in 528-535 AD. the Corpus Juris Civils, in which latter form it has come down to us.  A great many other sources i.e., literature, inscriptions, papyri, have given additional information about the historical Roman law, and modern research has made a great deal of use of them, and has substantially changed former concepts of the development of the Roman Law.
