At the time that Hannibal set out for Italy, all the coast of Africa, from the Philænorum Aræ, by the great Syrtis, to the pillars of Hercules, was subject to the Carthaginians.(601) Passing through the straits, they had conquered all the western coast of Spain, along the ocean, as far as the Pyrenean hills. The coast, which lies on the Mediterranean, had been almost wholly subdued by them; and it was there they had built Carthagena; and they were masters of all the country, as far as the river Iberus, which bounded their dominions. Such was, at that time, the extent of their empire. In the centre of the country, some nations had indeed held out against all their efforts, and could not be subdued by them. _Conquests of the Carthaginians in Sicily._—The wars which the Carthaginians carried on in Sicily are more known. I shall here relate those which were waged from the reign of Xerxes, who first prompted the Carthaginians to carry their arms into Sicily, till the first Punic war. This period includes near two hundred and twenty years; _viz._ from the year of the world 3520 to 3738. At the breaking out of these wars, Syracuse, the most considerable as well as most powerful city of Sicily, had invested Gelon, Hiero, and Thrasybulus, (three brothers who succeeded one another,) with the sovereign power. After their deaths, a democracy or popular government was established in that city, and subsisted above sixty years. From this time, the two Dionysius’s, Timoleon, and Agathocles, bore the sway in Syracuse. Pyrrhus was afterwards invited into Sicily, but he kept possession of it only a few years. Such was the government of Sicily during the wars of which I am going to treat. They will give us great light with regard to the power of the Carthaginians, at the time that they began to be engaged in war with the Romans. Sicily is the largest and most considerable island in the Mediterranean. It is of a triangular form, and for that reason was called Trinacria and Triquetra. The eastern side, which faces the Ionian or Grecian sea, extends from Cape Pachynum(602) to Pelorum.(603) The most celebrated cities on this coast are Syracuse, Tauromenium, and Messana. The northern coast, which looks towards Italy, reaches from Cape Pelorum to Cape Lilybæum.(604) The most noted cities on this coast are Mylæ, Hymera, Panormus, Eryx, Motya, Lilybæum. The southern coast, which lies opposite to Africa, extends from Cape Lilybæum to Pachynum. The most remarkable cities on this coast are Selinus, Agrigentum, Gela, and Camarina. This island is separated from Italy by a strait, which is not more than a mile and a half over, and called the Faro or strait of Messina, from its contiguity to that city. The passage from Lilybæum to Africa is but 1500 furlongs,(605) that is, about seventy-five leagues.(606)
