The Gallic Wars-Caesar-Paragraph 1

All of Gaul is divided into three parts, one of which the Belgae live in, the second the Aquitani live in, the third of which the are called the Celts, and in our language are called the Gauls. All these differ between each other in language, customs, and laws. The Garonne River divides the Gauls from the Aquitani, and the Marne and the Seine divide them from the Belgians. Of all these, the Belgae are the bravest, because they are furthest from the culture and humanity of Province, and merchants least frequently resort to them, and import those things which tend to effeminate the mind; and they are the nearest to the Germans, who dwell beyond the Rhine, with whom they are continually waging war; for which reason the Helvetii also surpass the rest of the Gauls in valor, as they contend with the Germans in almost daily battles, when they either repel them from their own territories, or themselves wage war on their frontiers.
