latter attracted the attention even of the ancients, especially of the excellent Posidonius, who made so many correct observations, but allowed himself in this instance to be misled. He is of opinion that the Celts had immigrated into Spain, for he reasoned thus: as the Celts could migrate into Italy and across the Danube as far as the Dniepr, it was far less difficult for them to enter the neighbouring country of Spain. But such isolated parts of a nation cannot have arrived in a country by immigration; on the contrary, the Iberians appear extending themselves and in possession of Aquitania and Languedoc at a very early period; how then could the Celts, not being able to maintain the Pyrenees, have spread over the whole peninsula? It is probable, nay almost evident, that it was the Iberians that migrated and extended themselves, and this opinion agrees with the most ancient traditions of the Celts in Ammianus Marcellinus, according to which they were once masters of all the west of Europe, but were expelled from many parts. If we suppose that the Celts dwelt as far as the Sierra Morena, and that the Iberians, perhaps reinforced by their kinsmen from Africa, pressed them forward, this supposition would account for some Celtic ruins which are still extant, and the Celts may have capitulated in a manner similar to that described in the book of Joshua. As one part of England was occupied by Germans so completely as to destroy every trace of the ancient inhabitants, while elsewhere, as e.g., in Devonshire, the Britons, in large numbers, lived among the Germans and became mixed with them; so the Iberians expelled the ancient Celtic population, wherever the nature of the country did not protect it; but the Celts maintained themselves in the mountains between the Tagus and the Iberus, and the Iberians only subdued them, and then settled among them. In the course of time the two nations became amalgamated, and thus formed the Celtiberians, whose character, however, is essentially Iberian.
