Scaling-ladders were applied at the dawn of day; the presence of Cabades, his stern command, and his drawn sword, compelled the Persians to vanquish; and before it was sheathed, fourscore thousand of the inhabitants had expiated the blood of their companions. After the siege of Amida, the war continued three years, and the unhappy frontier tasted the full measure of its calamities. The gold of Anastasius was offered too late, the number of his troops was defeated by the number of their generals; the country was stripped of its inhabitants, and both the living and the dead were abandoned to the wild beasts of the desert. The resistance of Edessa, and the deficiency of spoil, inclined the mind of Cabades to peace: he sold his conquests for an exorbitant price; and the same line, though marked with slaughter and devastation, still separated the two empires. To avert the repetition of the same evils, Anastasius resolved to found a new colony, so strong, that it should defy the power of the Persian, so far advanced towards Assyria, that its stationary troops might defend the province by the menace or operation of offensive war. For this purpose, the town of Dara, 137 fourteen miles from Nisibis, and four days’ journey from the Tigris, was peopled and adorned; the hasty works of Anastasius were improved by the perseverance of Justinian; and, without insisting on places less important, the fortifications of Dara may represent the military architecture of the age. The city was surrounded with two walls, and the interval between them, of fifty paces, afforded a retreat to the cattle of the besieged. The inner wall was a monument of strength and beauty: it measured sixty feet from the ground, and the height of the towers was one hundred feet; the loopholes, from whence an enemy might be annoyed with missile weapons, were small, but numerous; the soldiers were planted along the rampart, under the shelter of double galleries, and a third platform, spacious and secure, was raised on the summit of the towers. The exterior wall appears to have been less lofty, but more solid; and each tower was protected by a quadrangular bulwark. A hard, rocky soil resisted the tools of the miners, and on the south-east, where the ground was more tractable, their approach was retarded by a new work, which advanced in the shape of a half-moon. The double and treble ditches were filled with a stream of water; and in the management of the river, the most skilful labor was employed to supply the inhabitants, to distress the besiegers, and to prevent the mischiefs of a natural or artificial inundation. Dara continued more than sixty years to fulfil the wishes of its founders, and
