it had been carried in the time of Augustus;[30] as to which probably the chief regulative consideration was the restricted right of levy in regard to those who were citizens of the empire. [Sidenote: Romanising of the Iberians.] The indigenous population of Spain, which thus became partly mixed up with Italian settlers, partly led towards Italian habits and language, nowhere emerges so as to be clearly recognised in the history of the imperial period. Probably that stock, whose remains and whose language maintain their ground up to the present day in the mountains of Biscay, Guipuscoa, and Navarre, once filled the whole peninsula, as the Berbers filled the region of north Africa. Their language, different from the Indo-Germanic, and destitute of flexion like that of the Finns and Mongols, proves their original independence; and their most important memorials, the coins, in the first century of the Roman rule in Spain embrace the peninsula, with the exception of the south coast from Cadiz to Granada, where the Phoenician language then prevailed, and of the region northward of the mouth of the Tagus and westward of the sources of the Ebro, which was then probably to a large extent practically independent, and certainly was utterly uncivilised. In this Iberian territory the south-Spanish writing is clearly distinguished from that of the north province; but not less clearly both are branches of one stock. The Phoenician immigration here confined itself to still narrower bounds than in Africa, and the Celtic mixture did not modify the general uniformity of the national development in a way that we can recognise. But the conflicts of the Romans with the Iberians belong mainly to the republican epoch, and have been formerly described (ii. 221 f.) {ii. 209 f.}. After the already mentioned last passages of arms under the first dynasty, the Iberians vanish wholly out of sight. To the question, how far they became Romanised in the imperial period, the information that has come to us gives no satisfactory answer. That in the intercourse with their former masters they would have always occasion to make use of the Roman language, needs no proof; but under the influence of Rome the national language and the national writing disappear even from public use within their own communities. Already in the last century of the republic the native coinage, which at first was to a large extent allowed, had become in the main set aside; from the imperial period there is no Spanish civic coin with other than a Latin legend.[31] [Sidenote: Language.]
