Nor are evidences wanting of its continued use in Gaul. When the names of towns Augustodunum (Autun), Augustonemētum (Clermont), Augustobona (Troyes), and various similar ones arose, Celtic was necessarily still spoken even in middle Gaul. Arrian, under Hadrian, gives in his disquisition on cavalry, the Celtic expression for particular manœuvres borrowed from the Celts. Irenaeus, a Greek by birth, who towards the end of the second century acted as a clergyman in Lyons, excuses the defects of his style by saying that he lives in the country of the Celts, and is compelled constantly to speak in a barbarian language. In a juristic treatise from the beginning of the third century, in contrast to the rule of law that testamentary directions in general are to be drawn up in Latin or Greek, any other language, _e.g._, Punic or Gallic, is allowed for _fidei commissa_. The emperor Alexander had his end announced to him by a Gallic fortune-teller in the Gallic language. Further, the church father Jerome, who had been himself in Ancyra as well as in Treves, assures us that the Galatians of Asia Minor and the Treveri of his time spoke nearly the same language, and compares the corrupt Gallic of the Asiatic with the corrupt Punic of the African. The Celtic language has maintained itself in Brittany, just as in Wales, to the present day; but while the province no doubt obtained its present name from the insular Britons who, in the fifth century fled thither before the Saxons, the language was hardly imported for the first time with these, but was to all appearance handed down from one generation to another there for thousands of years. In the rest of Gaul naturally during the course of the imperial period Roman habits step by step gained ground; but the Celtic idiom was put an end to here, not so much by the Germanic immigration as by the Christianising of Gaul, which did not, as in Syria and Egypt, adopt and make a vehicle of the language of the country that was set aside by the government, but preached the Gospel in Latin.
