Far back among the shadows of prehistoric times, a horde of Celts swarmed over the Pyrenees into this land of the Iberians, encountering possibly a still earlier race, whose descendants of to-day are the Basques. The Celts swerved to the west and settled in what now is Portugal and Gallicia. In civilization and physique, the invaders were much superior to the Iberians. As the centuries rolled on, the two peoples fought for mastery. They gradually blended in the central part of Spain, while the Celts continued dominant in the west and northwest of the peninsula, and the Iberians held their own in the east and south.
