If we may credit the ancient historians, the Etrurians or Tyrrhenians, even before the reign of Minos, had been for a long time masters of the greatest part of the Mediterranean Sea, and had given their name to the Tyrrhenian Sea, upon which they were situate. Piracy, as well as commerce, was followed by them; and they became at last so expert, successful, and dangerous, for their piracies, that they were attacked, and their maritime power greatly abridged, by the Carthaginians and the Sicilians. Their most famous port was Luna, which was situated on the Macra, a river which, flowing from the Apennines, divided Liguria from Etruria, and fell into the Tyrrhenian Sea. There seems good reason to believe that Luna was a place of great trade before the Trojan war; it was extremely capacious, and in every respect worthy of the commercial enterprise and wealth of the Tuscans. Populonium, a city which was situate on a high promontory of the same name, that ran a considerable way into the sea, also possessed a very commodious harbour, capable of receiving a great number of ships. It had an arsenal well supplied with all kinds of naval stores, and a quay for shipping or landing merchandize. One of the principal articles of export consisted in copper vessels, and in arms, machines, utensils, &c. of iron: these metals were at first supplied to the inhabitants from the island of Æthalia (now Elba); but the copper-mines there failing, iron alone, from the same island, was imported for the purpose of their various manufactures; the trade in these flourished in very remote times, and continued in the days of Aristotle and Strabo.
