[PAPINIANUS libro decimo quaestionum. ] §18.7.5.prCui pacto uenditoris pomerio cuiuslibet ciuitatis interdictum est, Urbe etiam interdictum esse uidetur.
[PAPINIANUS in the tenth book of Questions.] He who, by an agreement of the seller, has been forbidden the pomerium of any city, is deemed to be forbidden the City as well.
quod quidem alias cum principum mandatis praeciperetur, etiam naturalem habet intellectum, ne scilicet qui careret minoribus, fruatur maioribus.
Although this indeed is prescribed elsewhere by the mandates of the emperors, it also has a natural rationale, namely, that he who is deprived of lesser things should not enjoy greater things.
