We cannot say whether the Romans appreciated scenery. If a love of the wildly beautiful in nature is dependent upon the safety of those who behold it, and upon the ease with which those scenes are visited, perhaps only the later generations of Roman colonists could have possessed this sense. The earlier Romans who made their splendid system of roads were, doubtless, only military men, and, well aware of their dangers, found nothing beautiful in mountain ranges. Their successors, however, during four hundred years had leisure and plentiful opportunities of cultivating taste, and travel was highly organised among them. A milliare, or milestone, was placed at every Roman mile—4854 English feet—and “mansiones,” or posting-stations, at distances varying from seven to twenty miles. Roman roads were scientifically constructed. The following was the formula:— I. Pavimentum, or foundation. Fine earth, hard beaten in. II. Statumen, or bed of the road. Composed of large stones, sometimes mixed with mortar. III. Ruderatio. Small stones, well mixed with mortar. IV. Nucleus. Formed by mixing lime, chalk, pounded brick, or tile; or gravel, sand, and lime mixed with clay. V. Summum Dorsum. Surface of the paved road. So thoroughly well was the work done that remains of these roads are even now discovered, in a perfect condition, although buried from six to fifteen feet, or even deeper, beneath the present surface of the land, owing to the hundreds of years of neglect which followed the abandonment of Britain, and the decay of Roman civilisation; a neglect which allowed storms and the gradual effects of the weather to accumulate deposits of earth upon these paved ways until they were made to disappear as effectually as Pompeii and Herculaneum under the hail of ashes and lava that hid those cities from view for eighteen hundred years.
