Having now finished the circuit of the Roman empire, we may observe, that Africa is divided from Spain by a narrow strait of about twelve miles, through which the Atlantic flows into the Mediterranean. The columns of Hercules, so famous among the ancients, were two mountains which seemed to have been torn asunder by some convulsion of the elements; and at the foot of the European mountain, the fortress of Gibraltar is now seated. The whole extent of the Mediterranean Sea, its coasts and its islands, were comprised within the Roman dominion. Of the larger islands, the two Baleares, which derive their name of Majorca and Minorca from their respective size, are subject at present, the former to Spain, the latter to Great Britain. * It is easier to deplore the fate, than to describe the actual condition, of Corsica. Two Italian sovereigns assume a regal title from Sardinia and Sicily. Crete, or Candia, with Cyprus, and most of the smaller islands of Greece and Asia, have been subdued by the Turkish arms, whilst the little rock of Malta defies their power, and has emerged, under the government of its military Order, into fame and opulence. This long enumeration of provinces, whose broken fragments have formed so many powerful kingdoms, might almost induce us to forgive the vanity or ignorance of the ancients. Dazzled with the extensive sway, the irresistible strength, and the real or affected moderation of the emperors, they permitted themselves to despise, and sometimes to forget, the outlying countries which had been left in the enjoyment of a barbarous independence; and they gradually usurped the license of confounding the Roman monarchy with the globe of the earth. But the temper, as well as knowledge, of a modern historian, require a more sober and accurate language. He may impress a juster image of the greatness of Rome, by observing that the empire was above two thousand miles in breadth, from the wall of Antoninus and the northern limits of Dacia, to Mount Atlas and the tropic of Cancer; that it extended in length more than three thousand miles from the Western Ocean to the Euphrates; that it was situated in the finest part of the Temperate Zone, between the twenty-fourth and fifty-sixth degrees of northern latitude; and that it was supposed to contain above sixteen hundred thousand square miles, for the most part of fertile and well-cultivated land.
