[AFRICANUS libro sexto quaestionum. ] §45.1.63.prSi ita quis stipuletur: 'siue nauis ex Asia uenerit siue Titius consul factus fuerit', utra prius condicio exstitisset, stipulatio committetur et amplius committi non potest.
[AFRICANUS, Questions, Book 6] If anyone should stipulate thus: 'whether the ship shall have come from Asia, or Titius shall have been made consul', whichever condition should have occurred first, the stipulation will be realized, and it cannot be realized any further.
sed enim cum ex duabus disiunctiuis condicionibus altera defecerit, necesse est, ut ea, quae exstiterit, stipulationem committat.
But indeed, when one of the two disjunctive conditions has failed, it is necessary that the one which has occurred should realize the stipulation.
