Sicily and Italy were too far out of the way for the Asiatic Greeks, and they consequently held almost entirely aloof from any colonising expeditions thither. Rhodes was an exception. At the beginning of the seventh century its citizens, together with the Cretans, established the colony of Gela, on the fertile depression at the mouth of the Gela, which was the first Grecian city on the south coast of Sicily. About a century later (in 580) this city colonised Agrigentum, which is situated farther to the west on a steep height commanding a broad outlook, not far from the sea. This filled the gap which had been left in the row of Grecian cities between Gela and Selinus. At about the same time Rhodians and Cnidians under the leadership of the Heraclid Pentathlus, tried to find a footing on the most extreme west point of Sicily, on the promontory of Lilybæum. But the Hellenes were here successfully opposed by the Elymi, the original inhabitants of this part of the island, and by the citizens of the neighbouring Phœnician colony of Motya. The new settlers and their Selinuntine allies were beaten; Pentathlus himself fell, and the remainder of his people were forced to take refuge on the barren Liparæan Islands, which were thus won for the Grecians.
The distant west had been opened up to Grecian commerce even before this. It is said to have been a Samian sailor, Colœus by name, who, on a journey to Egypt, being carried out of his way by a storm off the Libyan coast, was the first to reach Tartessus, the rich silver-land, lying near the Pillars of Hercules (600 B.C.) At about the same time Ionic Phocæans founded the colony of Massalia not far from the mouth of the Rhodanus. This soon became a centre for the commerce of these regions and extended its influence far into the Celtic interior. From here the Phocæans advanced along the Iberian coast to Tartessus, where they entered into friendly relations with the natives and established the colony of Mænaca, which was the most westerly point the Hellenes ever held. The Phocæans settled also on Cyrnus (Corsica). In 565 they founded Alalia on the east coast of the island. When Ionia was forced to succumb to the Persians after the fall of Sardis (545) a large portion of the citizens of Phocæa left their homes and turned to their tribal kinsmen in Alalia, which thus grew from a mere mercantile settlement into a powerful city.
These results, however, were for the most part of short duration. The Phœnicians reached the western Mediterranean at the same time with the Hellenes, perhaps somewhat earlier even. The northern coast of Libya from Syrtis Major to the Pillars of Hercules was covered with a line of their settlements, among which Carthage attained the first place in the course of time, owing to the advantage of its incomparable location. It was not long before they crossed over to the islands lying opposite Africa. They occupied Melita (Malta) and Gaulos (Gozzo), and founded Motya, Panormus, and Solus in west Sicily, probably during the seventh century. Here the Greeks formed a barrier preventing their further expansion. The Phœnicians, however, could spread themselves upon Sardinia without hindrance, since the Greeks, although they may have planned to settle there, never went seriously about it. In this way a succession of Phœnician settlements grew up along the south and west coast of the island—Caralis, Nora, Sulci, Tharrus and others. The Pityusæ are said to have been colonised from Carthage in the year 654-653 B.C. The Phœnicians had already reached the silver-land of Tartessus in the eighth century. Their chief point of support in this region was Gades, situated on a small island beyond the Pillars of Hercules on the edge of the ocean.
