[GAIUS libro uicensimo sexto ad edictum prouinciale. ] §41.2.15.prRem, quae nobis subrepta est, perinde intellegimur desinere possidere atque eam, quae ui nobis erepta est.
[GAIUS, in the twenty-sixth book on the Provincial Edict.] We are understood to cease to possess a thing which has been stolen from us, just as much as one which has been taken from us by force.
sed si is, qui in potestate nostra est, subripuerit, quamdiu apud ipsum sit res, tamdiu non amittimus possessionem, quia per huiusmodi personas adquiritur nobis possessio.
But if a person who is in our power steals it, as long as the thing is with him, so long we do not lose possession, because possession is acquired for us through persons of this kind.
et haec ratio est, quare uideamur fugitiuum possidere, quod is, quemadmodum aliarum rerum possessionem interuertere non potest, ita ne suam quidem potest.
And this is the reason why we are deemed to possess a runaway slave, because, just as he cannot embezzle the possession of other things, so he cannot embezzle even his own.
