The Celts, however, did not exterminate the whole Euskarian people; they were too few in number and too far advanced in civilisation for such a course. They knew it was better to make them slaves than to destroy them: for the Celts had just reached, but had not yet got beyond, the slave-making stage of culture. To this day, people of mixed Euskarian parentage, and marked by the long skull, dark complexion, and black eyes of the Euskarian type, form a large proportion of the English peasantry; and they are found even in Sussex, which subsequently suffered more than most other parts of Britain from the destructive deluge of Teutonic barbarism in the fifth century. But though the Celts did not exterminate the Euskarians, they completely Celticised them, just as the Teuton is now Teutonising the old population of Scotland, Wales, and Ireland. In South Wales and elsewhere, indeed, the aborigines retained their own language and institutions, as Silures and so forth; but in the conquered districts of southern and eastern Britain they learned the tongue of their masters, and came to be counted as Celtic serfs. Thus, at the time when Britain comes forth into the full historic glare of Roman civilisation, we find the country inhabited by a Celtic aristocracy of Aryan type--round-headed, fair-haired, and blue-eyed; together-with a _plebs_ of Celticised Euskarian or half-caste serfs, retaining, as they still retain, the long skulls and dark complexions of their aboriginal ancestors. This was the ethnical composition of the Sussex population at the date of the first Roman invasions.
