Who the first inhabitants of Britain were, whether natives or immigrants, remains obscure; one must remember we are dealing with barbarians. But physical characteristics vary, and that very variation is suggestive. The reddish hair and large limbs of the Caledonians proclaim a German origin, the swarthy faces of the Silures, the tendency of their hair to curl and the fact that Spain lies opposite, all lead one to believe that Spaniards crossed in ancient times and occupied the land. The peoples nearest to the Gauls are correspondingly like them.
