Those ancients who roamed and cultivated the plains of modern France, Spain, Ireland, Scotland, and Germany, among others, will never have the same glory as Romans or other ancient peoples who inhabited the area. But like Rome, their influence and spread of culture was vast and impressive. We mostly know think of that culture as barbarous and subject to Rome, forgetting that they built impressive trade practices, warriors, and art. They were the Celts?a tough as nails culture rich in diversity as much as it was gold. They approached war the same way many great cultures did, always understanding that nothing can get into a closed fist. You must fight.
