[MODESTINUS libro octauo differentiarum. ] §21.1.62.prAd res donatas edictum aedilium curulium non pertinere dicendum est: etenim quid se restituturum donator repromittit, quando nullum pretium interueniat? quid ergo rei ab eo cui donata est melior facta sit, numquid quanti eius qui meliorem fecit interest donator conueniatur? quod minime dicendum est, ne eo casu liberalitatis suae donator poenam patiatur.
[MODESTINUS in the eighth book of Differences.] It must be said that the edict of the curule aediles does not apply to donated things; for what does the donor promise to restore, when no price intervenes? What if, therefore, a thing has been made better by the person to whom it was donated, should the donor be sued for as much as is the interest of the one who made it better? This is by no means to be said, lest in that case the donor suffer a penalty for his own liberality.
itaque si qua res donetur, necesse non erit ea repromittere, quae in rebus uenalibus aediles repromitti iubent.
Therefore, if any thing is donated, it will not be necessary to promise those things which the aediles order to be promised in the case of things for sale.
sane de dolo donator obligare se et debet et solet, ne quod benigne contulerit fraudis consilio reuocet.
Of course, the donor both ought to and usually does obligate himself with respect to fraud, lest he should revoke by a fraudulent design what he has kindly bestowed.
