[AFRICANUS libro primo quaestionum. ] §40.4.20.prSeruos legauit et cauit ita: 'rogo, si te promeruerunt, dignos eos libertate existimes'. praetoris hae partes sunt, ut cogat libertatem praestari, nisi si quid tale hi serui admiserint, ut indigni sint, quo libertatem consequantur, non etiam ut talia officia ab his exigantur, pro quibus libertatem mereri debent.
[AFRICANUS in the first book of Questions.] A certain person bequeathed slaves and provided as follows: 'I ask that, if they have deserved well of you, you consider them worthy of freedom.' It is the part of the praetor to compel that freedom be granted, unless these slaves have committed some such offence that they are unworthy to obtain freedom, and not also to require from them such services by which they ought to merit freedom.
arbitrium tamen eius erit qui rogatus sit, quo tempore quemque uelit manumittere, ita ut, si uiuus non manumississet, heres eius statim libertatem praestare cogatur.
Nevertheless, the choice of the time at which he wishes to manumit each one shall belong to the person requested, in such a way that if he has not manumitted them during his lifetime, his heir shall be compelled to grant freedom immediately.
