The author of the "Commentaries" was a Roman in whose eyes the state was every thing, the actual office-holder, dictator, consul, or praetor, a mere instrument for a short time; and he was too apt, like most of his countrymen, to judge of other nations by his own. We may conclude from the passage quoted that there was a supreme monarch in Gaul as well as in Ireland, and modern historians of Gaul have acknowledged it. But there is yet a stranger fact, which absolutely cannot be explained, save on the supposition that the Celts everywhere held the supreme dignity of extreme if not absolute importance in their political system. To give it the preeminence it deserves, we must refer to a subsequent event in the history of the Celts in Britain, since it happened there several centuries after Caesar, and we will quote the words of Augustin Thierry, who relates it: "After the retreat of the legions, recalled to Italy to protect the centre of the empire and Rome itself against the invasion of the Goths, the Britons ceased to acknowledge the power of the foreign governors set over their provinces and cities. The forms, the offices, the very spirit and language of the Roman administration disappeared; in their place was reconstituted the traditional authority of the clannish chieftains formerly abolished by Roman power. Ancient genealogies carefully preserved by the poets, called in the British language _bairdd_ - bards - helped to discover those who could pretend to the dignity of chieftains of tribes or families, tribe and family being synonymous in their language; and the ties of relationship formed the basis of their social state. Men of the lowest class, among that people, preserved in memory the long line of their ancestry with a care scarcely known to other nations, among the highest lords and princes. All the British Celts, poor or rich, had to establish their genealogy in order fully to enjoy their civil rights and secure their claim of property in the territory of the tribe. The whole belonging to a primitive family, no one could lay any claim to the soil, unless his relationship was well established. "At the top of this social order, composing a federation of small hereditary sovereignties, the Britons, freed from Roman power, constituted a high national sovereignty; they created a chieftain of chieftains, in their tongue called _Penteyrn_, that is to say, a _king of the whole_, in the language of their old annals. And they made him elective.--It was also formerly the custom in Gaul. --The object was to introduce into their system a kind of centralization, which, however, was always loose among Celtic tribes."--(_Conquete de l'Angleterre_, liv. i.)
