Tacitus, Germania. Chapter 35.
35. Thus far we have taken note of Western Germany. Northwards the country takes a vast sweep. First comes the tribe of the Chauci, which, beginning at the Frisian settlements, and occupying a part of the coast, stretches along the frontier of all the tribes which I have enumerated, till it reaches with a bend as far as the Chatti. This vast extent of country is not merely possessed, but densely peopled, by the Chauci, the noblest of the German races, a nation who would maintain their greatness by righteous dealing. Without ambition, without lawless violence, they live peaceful and secluded, never provoking a war or injuring others by rapine and robbery. Indeed, the crowning proof of their valour and their strength is, that they keep up their superiority without harm to others. Yet all have their weapons in readiness, and army if necessary, with a multitude of mena nd horses; and even while at peace they have the same renown of valour.
