These names were originally, given to all the people of the North and West of Europe; and it was not till Caesar's time that the Romans made any distinction between Celts and Germans. The name of Celts was then confined to the people north of the Pyrenees and west of the Rhine. Cf. Ammianus (xv. 9) ; Herodotus (iv. 49) ”
