DE HIS QVI SVI VEL ALIENI IVRIS SINT.
§ 48. Sequitur de iure personarum alia diuisio. nam quaedam personae sui iuris sunt, quaedam alieno iuri subiectae sunt. (Inst. 1, 8 pr.)
§ 49. Rursus earum personarum, quae alieno iuri subiectae sunt, aliae in potestate, aliae in manu, aliae in mancipio sunt. (Inst. l. c.)
§ 50. Videamus nunc de his quae alieno iuri subiectae sint; 〈nam〉 si cognouerimus quae istae personae sint, simul intellegemus quae sui iuris sint. (Inst. l. c.)
§ 51. Ac prius dispiciamus de iis qui in aliena potestate sunt. (Inst. l. c.)
§ 52. In potestate itaque sunt serui dominorum. quae quidem potestas iuris gentium est: nam apud omnes peraeque gentes animaduertere possumus dominis in seruos uitae necisque potestatem esse; et quodcumque per seruum adquiritur, id domino adquiritur. (Inst. 1, 8, 1.)
§ 53. Sed hoc tempore neque ciuibus Romanis, nec ullis aliis hominibus qui sub imperio populi Romani sunt, licet supra modum et sine causa in seruos suos saeuire; nam ex constitutione imperatoris Antonini qui sine causa seruum suum occiderit, non minus teneri iubetur, quam qui alienum seruum occiderit. sed et maior quoque asperitas dominorum per eiusdem principis constitutionem coercetur; nam consultus a quibusdam praesidibus prouinciarum de his seruis, qui ad fana deorum uel ad statuas principum confugiunt, praecepit ut si intolerabilis uideatur dominorum saeuitia cogantur seruos suos uendere. et utrumque recte fit; male enim nostro iure uti non debemus; qua ratione et prodigis interdicitur bonorum suorum administratio. (Inst. 1, 8, 2.)
§ 54. Ceterum cum apud ciues Romanos duplex sit dominium (nam uel in bonis uel ex iure Quiritium uel ex utroque iure cuiusque seruus esse intellegitur), ita demum seruum in potestate domini esse dicemus, si in bonis eius sit, etiamsi simul ex iure Quiritium eiusdem non sit; nam qui nudum ius Quiritium in seruo habet, is potestatem habere non intellegitur.
DE PATRIA POTESTATE.
§ 55. Item in potestate nostra sunt liberi nostri quos iustis nuptiis procreauimus. quod ius proprium ciuium Romanorum est; fere enim nulli alii sunt homines qui talem in filios suos habent potestatem qualem nos habemus. idque diuus Hadrianus edicto quod proposuit de his, qui sibi liberisque suis ab eo ciuitatem Romanam petebant, significauit. nec me praeterit Galatarum gentem credere in potestate parentum liberos esse. (Inst. 1, 9 pr.)
ON THOSE WHO ARE EITHER UNDER THEIR OWN POWER OR THAT OF ANOTHER.
§ 48. Another division in the law of Persons classifies men as either dependent or independent.
§ 49. Those who are dependent or subject to a superior, are either in his power, in his hand, or in his mancipation.
§ 50. Let us first explain what persons are dependent on a superior, and then we shall know what persons are independent.
§ 51. Of persons subject to a superior, let us first examine who are in his power.
§ 52. Slaves are in the power of their proprietors, a power recognized by jus gentium, since all nations present the spectacle of masters invested with power of life and death over slaves; and (by the Roman law) the owner acquires everything acquired by the slave.
§ 53. But in the present day neither Roman citizens, nor any other persons under the empire of the Roman people, are permitted to indulge in excessive or causeless harshness towards their slaves. By a constitution of the Emperor Antoninus, a man who kills a slave of whom he is owner, is as liable to punishment as a man who kills a slave of whom he is not owner: and inordinate cruelty on the part of owners is checked by another constitution whereby the same emperor, in answer to inquiries from presidents of provinces concerning slaves who take refuge at temples of the gods, or statues of the emperor, commanded that on proof of intolerable cruelty a proprietor should be compelled to sell his slaves: and both ordinances are just, for we ought not to make a bad use of our lawful rights, a principle recognized in the interdiction of prodigals from the administration of their fortune.
§ 54. But as citizens of Rome may have a double kind of dominion, either bonitary or quiritary, or a union of both bonitary and quiritary dominion, a slave is in the power of an owner who has bonitary dominion over him, even unaccompanied with quiritary dominion; if an owner has only bare quiritary dominion he is not deemed to have the slave in his power.
ON THE POWER OF THE FATHER.
§ 55. Again, a man has power over his own children begotten in civil wedlock, a right peculiar to citizens of Rome, for there is scarcely any other nation where fathers are invested with such power over their children as at Rome; and this the late Emperor Hadrian declared in the edict he published respecting certain petitioners for a grant of Roman citizenship to themselves and their children; though I am aware that among the Galatians parents are invested with power over their children.
