[GAIUS libro primo institutionum. ] §1.6.1.prDe iure personarum alia diuisio sequitur, quod quaedam personae sui iuris sunt, quaedam alieno iuri subiectae sunt.
[GAIUS in the first book of the Institutes.] Another division follows concerning the law of persons, namely, that some persons are of their own right, and some are subject to the right of another.
uideamus itaque de his, quae alieno iuri subiectae sunt: nam si cognouerimus quae istae personae sunt, simul intellegemus quae sui iuris sunt.
Let us therefore look at those who are subject to the right of another; for if we learn who these persons are, we shall at the same time understand who are of their own right.
dispiciamus itaque de his, quae in aliena potestate sunt.
Let us therefore examine those who are in the power of another.
§1.6.1.1Igitur in potestate sunt serui dominorum (quae quidem potestas iuris gentium est: nam apud omnes peraeque gentes animaduertere possumus dominis in seruos uitae necisque potestatem fuisse) et quodcumque per seruum adquiritur, id domino adquiritur.
Now, slaves are in the power of their masters (which power is indeed of the law of nations, for we can observe that among all nations alike, masters had the power of life and death over their slaves) and whatever is acquired through a slave is acquired for the master.
§1.6.1.2Sed hoc tempore nullis hominibus, qui sub imperio Romano sunt, licet supra modum et sine causa legibus cognita in seruos suos saeuire.
But at the present time, no persons who are under the Roman empire are permitted to rage against their slaves excessively and without a cause recognized by the laws.
nam ex constitutione diui Antonini qui sine causa seruum suum occiderit, non minus puniri iubetur, quam qui alienum seruum occiderit.
For according to a constitution of the divine Antoninus, anyone who kills his own slave without a cause is ordered to be punished no less than one who kills another's slave.
sed et maior asperitas dominorum eiusdem principis constitutione coercetur.
But also the excessive severity of masters is restrained by a constitution of the same emperor.
