in this legend celts and teutons are primeval and immutable creatures , like a triceratops and a stegosaurus ( bigger than a rhinoceros and more pugnacious , as popular palaeontologists depict them ) , fixed not only in shape but in innate and mutual hostility , and endowed even in the mists of antiquity , as ever since , with the peculiarities of mind and temper which can be still observed in the irish or the welsh on the one hand and the english on the other : the wild incalculable poetic celt , full of vague and misty imaginations , and the saxon , solid and practical when not under the influence of beer .
