Naval Power of Carthage
But the empire of Libya was only half of the power of Carthage; its maritime and colonial dominion had acquired, during the same period, a not less powerful development.
In Spain the chief station of the Phoenicians was the primitive Tyrian settlement at Gades (Cadiz). Besides this they possessed to the west and east of it a chain of factories, and in the interior the region of the silver mines; so that they held nearly the modern Andalusia and Granada, or at least the coasts of these provinces.
They made no effort to acquire the interior from the warlike native nations; they were content with the possession of the mines and of the stations for traffic and for shell and other fisheries; and they had difficulty in maintaining their ground even in these against the adjoining tribes. It is probable that these possessions were not properly Carthaginian but Tyrian, and Gades was not reckoned among the cities tributary to Carthage; but practically, like all the western Phoenicians, it was under Carthaginian hegemony, as is shown by the aid sent by Carthage to the Gaditani against the natives, and by the institution of Carthaginian trading settlements to the westward of Gades.
Ebusus and the Baleares, again, were occupied by the Carthaginians themselves at an early period, partly for the fisheries, partly as advanced posts against the Massiliots, with whom furious conflicts were waged from these stations.
