The conclusions which I wish to draw in this lecture are: that neither Britain nor Ireland was colonised by the Celts until the Late Celtic period, corresponding to the period which followed the Bronze Age in these countries; that the Belgic or Celto-Germanic settlements were of still later date, and extended to Ireland as well as Britain; that the Belgic settlements in England were not so widespread as they are represented in modern British writers; and that the distinction between the ancient Gaels and Britons does not correspond to the distinction between the Celtae and Belgae of Gaul in Cæsar's time. III. THE PRE-CELTIC INHABITANTS OF IRELAND In the second lecture, I remarked how the name Iberians has been adopted to fill a vacuum as regards the naming of the population which occupied Great Britain and Ireland before the Celtic immigration. This kind of naming is unscientific and misleading. It implies that the ancient population thus artificially named can be identified as a branch of the population which actually bore that name in Greek and Latin literature. From this implied identification other equally unwarranted assumptions are likely to follow. Rhys expended a vast amount of study, ingenuity, and argument in the effort to show that very definite traces of a language akin to modern Basque survived in ancient Ireland and Scotland. On this point it may be remarked that we do not even know that the Basque population was originally Iberian. Ethnologists are agreed that, apart altogether from the Celtic migrations, there must have been a mixture of very distinct races in south-western Europe in prehistoric times. If there was a mixture of races, there was also no doubt more than one language, and if the Basque language has been able to survive the conquests of Celt and Roman and Goth, and last until our own time it may also well have survived the extinction of other languages in south western Europe. So far as the Iberian theory is not mere vacuum-filling, it appears to rest on a single passage of Tacitus. He is describing the Silures, a British people whose territory was in the south of Wales, and who offered a very fierce resistance to the Romans. "The swarthy complexion of the Silures," he says, "the prevalence of curly hair among them, and their position over against Spain, argue that the ancient Iberians must have crossed over [from Spain] and occupied their territory." We have often heard the occurrence of similar physical traits in the west of Ireland ascribed to a more recent Spanish mixture. It all amounts to this, which Irish tradition bears out, and which nobody questions, that these western isles contain descendants of an ancient dark-complexioned population, probably already of mixed race, which existed in western Europe before the arrival of the fair-complexioned people, whose distinctive features appear by all indications to have originated in the lands forming the basin of the Baltic Sea.
