It was the proud boast of the ancient Romans that all roads led to their city. Rome was the centre and mistress of the world; and as the loneliest rill that rises in the bosom of the far-off mountain leads, if followed, to the ocean, so every path in the remotest corner of the vast empire conducted to the great gilded column in the Roman Forum, upon which all distances without the walls were marked. To the Romans the world is indebted for opening up communications with different countries.
