FORTIFICATIONS The fortifications of Europe and Asia were multiplied by Justinian; but the repetition of those timid and fruitless precautions exposes to a philosophic eye the debility of the empire. From Belgrade to the Euxine, from the conflux of the Save to the mouth of the Danube, a chain of above fourscore fortified places was extended along the banks of the great river. Single watch-towers were changed into spacious citadels; vacant walls, which the engineers contracted or enlarged according to the nature of the ground, were filled with colonies or garrisons; a strong fortress defended the ruins of Trajan’s bridge, and several military stations affected to spread beyond the Danube the pride of the Roman name. But that name was divested of its terrors; the barbarians, in their annual inroads, passed and contemptuously repassed before these useless bulwarks; and the inhabitants of the frontier, instead of reposing under the shadow of the general defence, were compelled to guard, with incessant vigilance, their separate habitations. The solitude of ancient cities was replenished; the new foundations of Justinian acquired, perhaps too hastily, the epithets of impregnable and populous; and the auspicious place of his own nativity attracted the grateful reverence of the vainest of princes. Under the name of _Justiniana Prima_, the obscure village of Tauresium became the seat of an archbishop and a prefect, whose jurisdiction extended over seven warlike provinces of Illyricum, and the corrupt appellation of _Giustendil_ still indicates, about twenty miles to the south of Sophia, the residence of a Turkish sanjak. For the use of the emperor’s countrymen, a cathedral, a palace, and an aqueduct were speedily constructed; the public and private edifices were adapted to the greatness of a royal city; and the strength of the walls resisted, during the lifetime of Justinian, the unskilful assaults of the Huns and Slavonians. Their progress was sometimes retarded, and their hopes of rapine were disappointed, by the innumerable castles which, in the provinces of Dacia, Epirus, Thessaly, Macedonia, and Thrace, appear to cover the whole face of the country. Six hundred of these forts were built or repaired by the emperor: but it seems reasonable to believe that the far greater part consisted only of a stone or brick tower, in the midst of a square or circular area, which was surrounded by a wall and ditch, and afforded in a moment of danger some protection to the peasants and cattle of the neighbouring villages.
