THE AREA covered by Celtic domain at the height of its expansion in the third century B.C. was enormous, encompassing no less than the British Isles, France, the western Iberian peninsula, a large part of northern. Italy, most of Germany, the Low Countries, Czechoslovakia, Austria, Hungary, a major portion of the Balkans, and Galatia in Asia Minor. And we have reason to assume that as far as the Celtic realm extended, so did the power and influence of the Druids. Everywhere evidence speaks strongly for the cultural, if not political, unity of the people.
