[ALFENUS VARUS libro secundo digestorum. ] §18.6.12.prSi uendita insula combusta esset, cum incendium sine culpa fieri non possit, quid iuris sit? respondit: quia sine patris familias culpa fieri potest neque, si seruorum neglegentia factum esset, continuo dominus in culpa erit, quam ob rem si uenditor eam diligentiam adhibuisset in insula custodienda, quam debent homines frugi et diligentes praestare, si quid accidisset, nihil ad eum pertinebit.
[ALFENUS VARUS in the second book of the Digests.] If a sold insula was burned, since a fire cannot occur without fault, what is the law? He answered: Because it can occur without the fault of a paterfamilias, and even if it should have occurred through the negligence of slaves, the master will not immediately be at fault; wherefore, if the seller had exercised such diligence in guarding the insula as honest and diligent men ought to provide, if anything should have happened, nothing will pertain to him.
