      Hence, in Tac., in barbarum, adverb., in the manner or according to the custom of foreigners or barbarians: civitas potens, neque in barbarum corrupta, Tac. A. 6, 42; id. H. 5, 2.
      As subst.: barbărus, i, m., a foreigner, stranger, barbarian: sin hoc et ratio doctis et necessitas barbaris praescripsit, Cic. Mil. 11, 30; id. Verr. 2, 4, 50, § 112; 2, 5, 60, § 157: quo neque noster adit quisquam, nec barbarus audet, Lucr. 6, 37: quippe simul nobis habitat discrimine nullo Barbarus, Ov. Tr. 5, 10, 30: barbarorum soli prope Germani singulis uxoribus contenti, Tac. G. 18: barbari praestabant non modicam humanitatem, Vulg. Act. 28, 1.
