adjacent country, consisted of several strata of sand, gravel, and cement, and was paved with large stones, or, in some places near the capital, with granite. 87 Such was the solid construction of the Roman highways, whose firmness has not entirely yielded to the effort of fifteen centuries. They united the subjects of the most distant provinces by an easy and familiar intercourse; but their primary object had been to facilitate the marches of the legions; nor was any country considered as completely subdued, till it had been rendered, in all its parts, pervious to the arms and authority of the conqueror. The advantage of receiving the earliest intelligence, and of conveying their orders with celerity, induced the emperors to establish, throughout their extensive dominions, the regular institution of posts. 88 Houses were everywhere erected at the distance only of five or six miles; each of them was constantly provided with forty horses, and by the help of these relays, it was easy to travel a hundred miles in a day along the Roman roads. 89 891 The use of posts was allowed to those who claimed it by an Imperial mandate; but though originally intended for the public service, it was sometimes indulged to the business or conveniency of private citizens. 90 Nor was the communication of the Roman empire less free and open by sea than it was by land. The provinces surrounded and enclosed the Mediterranean: and Italy, in the shape of an immense promontory, advanced into the midst of that great lake. The coasts of Italy are, in general, destitute of safe harbors; but human industry had corrected the deficiencies of nature; and the artificial port of Ostia, in particular, situate at the mouth of the Tyber, and formed by the emperor Claudius, was a useful monument of Roman greatness. 91 From this port, which was only sixteen miles from the capital, a favorable breeze frequently carried vessels in seven days to the columns of Hercules, and in nine or ten, to Alexandria in Egypt. 92

He began his journey at night, was in Cappadocia (165 miles from Antioch) the ensuing evening, and arrived at Constantinople the sixth day about noon. The whole distance was 725 Roman, or 665 English miles. See Libanius, Orat. xxii., and the Itineria, p. 572—581. Note: A courier is mentioned in Walpole’s Travels, ii. 335, who was to travel from Aleppo to Constantinople, more than 700 miles, in eight days, an unusually short journey.—M.]
