The passage would have been easy from Sardinia to Corsica, which is not more than seven miles distant from it; but Corsica seems to have possessed no attraction for the Phoenicians proper, who were perhaps deterred from colonising it by its unhealthiness, or by the savagery of its inhabitants. Or they may have feared to provoke the jealousy of the Tyrrhenians, off whose coast the island lay, and who, without having any colonising spirit themselves, disliked the too near approach of rivals.[5139] At any rate, whatever the cause, it seems to have been left to the Carthaginians, to bring Corsica within the range of Phoenician influence; and even the Carthaginians did little more than hold a few points on its shores as stations for their ships.[5140] If from Sardinia the Phoenicians ventured on an exploring voyage westward into the open Mediterranean, a day’s sail would bring them within sight of the eastern Balearic Islands, Minorca and Majorca. The sierra of Majorca rises to the height of between 3,000 and 4,000 feet,[5141] and can be seen from a great distance. The occupation of the islands by “the Phoenicians” is asserted by Strabo,[5142] but we cannot be sure that he does not mean Phoenicians of Africa, i.e. Carthaginians. Still, on the whole, modern criticism inclines to the belief that, even before the foundation of Carthage, Phoenician colonisation had made its way into the Balearic Islands, directly, from the Syrian coast.[5143] Some resting-places between the middle Mediterranean and Southern Spain must have been a necessity; and as the North African coast west of Hippo offered no good harbours, it was necessary to seek them elsewhere. Now Minorca has in Port Mahon a harbour of almost unsurpassed excellence,[5144] while in Majorca there are fairly good ports both at Palma and at Aleudia.[5145] Ivica is less well provided, but there is one of some size, known as Pormany (i.e. “Porta magna”), on the western side of the island, and another, much frequented by fishing-boats,[5146] on the south coast near Ibiza. The productions of the Balearides were not, perhaps, in the early times of much importance, since the islands are not, like Sardinia, rich in metals, nor were the inhabitants sufficiently civilised to furnish food supplies or native manufactures in any quantity. If, then, the Phoenicians held them, it must have been altogether for the sake of their harbours.
