this colonial system, especially in Athens, the business of ship-building and navigation was so extensively prosecuted as to give a special character to public life. In other parts of Greece, as in Sparta, it was altogether different. In that state the laws of Lycurgus had abolished private property; all things were held in common; savage life was reduced to a system, and therefore there was no object in commerce. But in Athens, commerce was regarded as being so far from dishonourable that some of the most illustrious men, whose names have descended to us as philosophers, were occupied with mercantile pursuits. Aristotle kept a druggist's shop in Athens, and Plato sold oil in Egypt. [Sidenote: Carthaginian supremacy in the Mediterranean.] It was the intention of Athens, had she succeeded in the conquest of Sicily, to make an attempt upon Carthage, foreseeing therein the dominion of the Mediterranean, as was actually realized subsequently by Rome. The destruction of that city constituted the point of ascendancy in the history of the Great Republic. Carthage stood upon a peninsula forty-five miles round, with a neck only three miles across. Her territory has been estimated as having a sea-line of not less than 1400 miles, and containing 300 towns; she had also possessions in Spain, in Sicily, and other Mediterranean islands, acquired, not by conquest, but by colonization. In the silver mines of Spain she employed not less than forty thousand men. In these respects she was guided by the maxims of her Phoenician ancestry, for the Tyrians had colonized for depôts, and had forty stations of that kind in the Mediterranean. Indeed, Carthage herself originated in that way, owing her development to the position she held at the junction of the east and west basins. The Carthaginian merchants did not carry for hire, but dealt in their commodities. This implied an extensive system of depôts and bonding. They had anticipated many of the devices of modern commerce. They effected insurances, made loans on bottomry, and it has been supposed that their leathern money may have been of the nature of our bank notes.
