The destruction of these two cities, Corinth and Carthage, together with other facts such as the unreasonable irritation which Rome displayed against her Greek allies, Rhodes and Pergamum, have been taken by some modern historians to indicate, once more, a policy of commercial jealousy instigating the destruction of rival markets. In the one case, however, it has been proved that Corinth was no longer a great centre of Greek commerce when she was destroyed, and in the case of Carthage it was the party of Cato, who was much more of a farmer than a company-promoter, that urged destruction. A man of business might indeed be foolish enough to want to close the principal markets which bought and sold with him--there are such business men to-day--but he would scarcely be so mad as to have a fine commercial centre with its docks and quays utterly destroyed and cursed for ever. Similarly, when Macedon was conquered her rich gold mines were shut down by order of the senate. The truth is that Rome was tired and exhausted with her colossal wars, irritable and nervous beyond expression with the gigantic task of government which she had found thrust upon her. Surrounded with false friends and secret enemies, she was losing the noble _sang froid_ she had displayed in times of real crisis. Corinth was destroyed as a warning to the Greeks, Carthage as an expiation for the _lemures_ of the unburied Roman dead. THE PROVINCES In considering the ancient, imperial, and provincial systems it is necessary for the modern to divest himself of all the geographical notions which spring from the study of maps. The ancients probably had only the most vague notions of territory. Natural frontiers such as mountains, rivers, and coasts were of course familiar to them, from the strategic point of view. Within those were cities great and small, which in the case of civilised people formed the units of life and government. In the case of barbarians there were tribes and nations, seldom sufficiently settled to produce any notion of geographical area. Thus when Rome conquered Sicily she was acquiring not so much one geographical unit, an island, as a collection of states of various types and constitutions. Similarly in the case of Spain; she said and thought that she acquired Spain, although the greater part of the Iberian peninsula remained unconquered for another century and a half. To remember the limitations of ancient geographical knowledge is essential to the understanding of the Roman provincial system. _Provincia_ means in the first instance a sphere of official duty, a man’s _provincia_ might be the feeding of the sacred geese or it might be the control of an army. It was not for a long time that the word came to connote a territorial area. When it did so, the day of the city-state was at an end.
