From Sicily and North Africa the tide of emigration naturally and easily flowed on into Sardinia, which is distant, from the former about 150 and from the latter about 115 miles. The points chosen by the Phoenician settlers lay in the more open and level region of the south and the south-west, and were all enclosed within a line which might be drawn from the coast a little east of Cagliari to the northern extremity of the Gulf of Oristano.[5131] The tract includes some mountain groups, but consists mainly of the long and now marshy plain, called the “Campidano,” which reaches across the island from Cagliari on the southern to Oristano on the western coast. This plain, if drained, would be by far the most fertile part of the island; and was in ancient times exceedingly productive in cereals, as we learn from Diodorus.[5132] The mountains west of it, especially those about Iglesias, contain rich veins of copper and of lead, together with a certain quantity of silver.[5133] Good harbours exist at Cagliari, at Oristano, and between the island of S. Antioco and the western shore. It was at these points especially that the Phoenicians made their settlements, the most important of which were Caralis (Cagliari), Nora, Sulcis, and Tharros. Caralis, or Cagliari, the present capital, lies at the bottom of a deep bay looking southwards, and has an excellent harbour, sheltered in all weathers. There are no remains of Phoenician buildings; but the neighbourhood yields abundant specimens of Phoenician art in the shape of tombs, statuettes, vases, bottles, and the like.[5134] Caralis was probably the first of the settlements made by the Phoenicians in Sardinia; it would attract them by its harbour, its mines, and the fertility of its neighbourhood. From Caralis they probably passed to Nora, which lay on the same bay to the south-west; and from Nora they rounded the south-western promontory of Sardinia, and established themselves on the small island now known as the Isola di San Antioco, where they built a town which they called Sulchis or Sulcis.[5135] Sulcis has yielded votive tablets of the Phoenician type, tombs, vases, &c.[5136] The island was productive of lead, and had an excellent harbour towards the north, and another more open one towards the south. Finally, mid-way on the west coast, at the northern extremity of the Gulf of Oristano, the Phoenicians occupied a small promontory which projects into the sea southwards and there formed a settlement which became known as Tharras or Tharros.[5137] Very extensive remains, quite unmistakably Phoenician, including tombs, cippi, statuettes in metal and clay, weapons, and the like, have been found on the site.[5138]
