The question as to how and whence the Celts entered Galicia has become of late years a thorny subject to Spanish students of Gallegan history, and a foreigner who has followed their discussions can hardly approach it without feeling that he is treading upon dangerous ground. I shall avoid taking it upon myself to decide which of the many theories put before the Spanish public is nearest to the truth. There are some who think that Galicia, Ireland, and America were once connected by land, and there are many who maintain that in prehistoric times there must have been a close maritime intercourse between Ireland and Galicia.
Both the Scotch and the Irish have traditions to the effect that the native races of Scotland and Ireland are descended from Spaniards. Curiously enough, I came across a proof of the freshness of such traditions in the minds of the Irish of my own day just as I was starting for Galicia in 1907. An Irish maid who was assisting me to prepare for my departure, on hearing that Spain was the destination of my journey, remarked, “That is the country my people came from. All the Irish came from Spain a long time ago.” “Are you quite sure?” I asked. “Yes,” she replied, “quite sure. Everybody in Ireland knows that; even the poor people know it.”
Some Spanish writers believe that the Celts, passing from Galicia to Ireland, crossed thence to England. “But if it is true,” says Aguiar, “that the English Celts came to France from England, how comes it that Julius Cæsar tells us that the Galli went to England to be instructed in the sciences?” Others are of the opinion that the earliest inhabitants of Galicia entered Spain at a much earlier date than that which the Gauls settled in France--Herodotus having written about Spanish Celts, but not about French ones. They believe that the Spanish Celts are a branch of the Cimmerians described by Herodotus as dwelling in the Crimea,[18] who disappeared completely from the neighbourhood of the Black Sea, and were thought to have settled in Wales under the name of Cimbri.[19] There have come down to our own times many geographical names, not only in Britain, but also in Galicia, containing the roots Cam, Camb, Cambr, Cim, and Cimbr.
