[ULPIANUS libro uicesimo octauo ad Sabinum. ] §18.1.11.prAlioquin quid dicemus, si caecus emptor fuit uel si in materia erratur uel in minus perito discernendarum materiarum? in corpus eos consensisse dicemus? et quemadmodum consensit, qui non uidit?
[ULPIANUS, in the twenty-eighth book on Sabinus.] Otherwise, what shall we say if the buyer was blind, or if a mistake is made regarding the material, or in the case of one who is less skilled in distinguishing materials? Shall we say that they agreed on the object itself? And how did he, who did not see, agree?
§18.1.11.1Quod si ego me uirginem emere putarem, cum esset iam mulier, emptio ualebit: in sexu enim non est erratum.
But if I should think that I am buying a virgin, when she is already a woman, the purchase will be valid; for there has been no mistake as to sex.
ceterum si ego mulierem uenderem, tu puerum emere existimasti, quia in sexu error est, nulla emptio, nulla uenditio est.
On the other hand, if I were selling a woman and you supposed you were buying a boy, since there is a mistake as to sex, there is no purchase and no sale.
