7 The edicts of the praetors too have no small legal authority, and these we are used to call the 'ius honorarium,' because those who occupy posts of honour in the state, in other words the magistrates, have given authority to this branch of law. The curule aediles also used to issue an edict relating to certain matters, which forms part of the ius honorarium.
8 The answers of those learned in the law are the opinions and views of persons authorized to determine and expound the law; for it was of old provided that certain persons should publicly interpret the laws, who were called jurisconsults, and whom the Emperor privileged to give formal answers. If they were unanimous the judge was forbidden by imperial constitution to depart from their opinion, so great was its authority.
9 The unwritten law is that which usage has approved: for ancient customs, when approved by consent of those who follow them, are like statute.
10 And this division of the civil law into two kinds seems not inappropriate, for it appears to have originated in the institutions of two states, namely Athens and Lacedaemon; it having been usual in the latter to commit to memory what was observed as law, while the Athenians observed only what they had made permanent in written statutes.
11 But the laws of nature, which are observed by all nations alike, are established, as it were, by divine providence, and remain ever fixed and immutable: but the municipal laws of each individual state are subject to frequent change, either by the tacit consent of the people, or by the subsequent enactment of another statute.
12 The whole of the law which we observe relates either to persons, or to things, or to actions. And first let us speak of persons: for it is useless to know the law without knowing the persons for whose sake it was established.
TITLE III. OF THE LAW OF PERSONS
In the law of persons, then, the first division is into free men and slaves.
1 Freedom, from which men are called free, is a man's natural power of doing what he pleases, so far as he is not prevented by force or law:
2 slavery is an institution of the law of nations, against nature subjecting one man to the dominion of another.
3 The name 'slave' is derived from the practice of generals to order the preservation and sale of captives, instead of killing them; hence they are also called mancipia, because they are taken from the enemy by the strong hand.
4 Slaves are either born so, their mothers being slaves themselves; or they become so, and this either by the law of nations, that is to say by capture in war, or by the civil law, as when a free man, over twenty years of age, collusively allows himself to be sold in order that he may share the purchase money.
5 The condition of all slaves is one and the same: in the conditions of free men there are many distinctions; to begin with, they are either free born, or made free.
TITLE IV. OF MEN FREE BORN
A freeborn man is one free from his birth, being the offspring of parents united in wedlock, whether both be free born or both made free, or one made free and the other free born. He is also free born if his mother be free even though his father be a slave, and so also is he whose paternity is uncertain, being the offspring of promiscuous intercourse, but whose mother is free. It is enough if the mother be free at the moment of birth, though a slave at that of conception: and conversely if she be free at the time of conception, and then becomes a slave before the birth of the child, the latter is held to be free born, on the ground that an unborn child ought not to be prejudiced by the mother's misfortune. Hence arose the question of whether the child of a woman is born free, or a slave, who, while pregnant, is manumitted, and then becomes a slave again before delivery. Marcellus thinks he is born free, for it is enough if the mother of an unborn infant is free at any moment between conception and delivery: and this view is right.
1 The status of a man born free is not prejudiced by his being placed in the position of a slave and then being manumitted: for it has been decided that manumission cannot stand in the way of rights acquired by birth.
TITLE V. OF FREEDMEN
Those are freedmen, or made free, who have been manumitted from legal slavery. Manumission is the giving of freedom; for while a man is in slavery he is subject to the power once known as 'manus'; and from that power he is set free by manumission. All this originated in the law of nations; for by natural law all men were born free—slavery, and by consequence manumission, being unknown. But afterwards slavery came in by the law of nations; and was followed by the boon of manumission; so that though we are all known by the common name of 'man,' three classes of men came into existence with the law of nations, namely men free born, slaves, and thirdly freedmen who had ceased to be slaves.
1 Manumission may take place in various ways; either in the holy church, according to the sacred constitutions, or by default in a fictitious vindication, or before friends, or by letter, or by testament or any other expression of a man's last will: and indeed there are many other modes in which freedom may be acquired, introduced by the constitutions of earlier emperors as well as by our own.
2 It is usual for slaves to be manumitted by their masters at any time, even when the magistrate is merely passing by, as for instance while the praetor or proconsul or governor of a province is going to the baths or the theatre.
3 Of freedmen there were formerly three grades; for those who were manumitted sometimes obtained a higher freedom fully recognised by the laws, and became Roman citizens; sometimes a lower form, becoming by the lex Iunia Norbana Latins; and sometimes finally a liberty still more circumscribed, being placed by the lex Aelia Sentia on the footing of enemies surrendered at discretion. This last and lowest class, however, has long ceased to exist, and the title of Latin also had become rare: and so in our goodness, which desires to raise and improve in every matter, we have amended this in two constitutions, and reintroduced the earlier usage; for in the earliest infancy of Rome there was but one simple type of liberty, namely that possessed by the manumitter, the only distinction possible being that the latter was free born, while the manumitted slave became a freedman. We have abolished the class of 'dediticii,' or enemies surrendered at discretion, by our constitution, published among those our decisions, by which, at the suggestion of the eminent Tribonian, our quaestor, we have set at rest the disputes of the older law. By another constitution, which shines brightly among the imperial enactments, and suggested by the same quaestor, we have altered the position of the 'Latini Iuniani,' and dispensed with all the rules relating to their condition; and have endowed with the citizenship of Rome all freedmen alike, without regard to the age of the person manuumitted, and nature of the master's ownership, or the mode of manumission, in accordance with the earlier usage; with the addition of many new modes in which freedom coupled with the Roman citizenship, the only kind of freedom now known may be bestowed on slaves.
TITLE VI. OF PERSONS UNABLE TO MANUMIT, AND THE CAUSES OF THEIR INCAPACITY
In some cases, however, manumission is not permitted; for an owner who would defraud his creditors by an intended manumission attempts in vain to manumit, the act being made of no effect by the
