110 (return) [ Procopius, l. viii. 29; most probably a stranger and wanderer, as the Mediterranean does not breed whales. Balaenae quoque in nostra maria penetrant, (Plin. Hist. Natur. ix. 2.) Between the polar circle and the tropic, the cetaceous animals of the ocean grow to the length of 50, 80, or 100 feet, (Hist. des Voyages, tom. xv. p. 289. Pennant’s British Zoology, vol. iii. p. 35.)] 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. 111 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, 112 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 præfect, whose jurisdiction extended over seven warlike provinces of Illyricum; 113 and the corrupt appellation of Giustendil still indicates, about twenty miles to the south of Sophia, the residence of a Turkish sanjak. 114 For the use of the emperor’s countryman, a cathedral, a place, 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 Sclavonians. 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, appeared 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
