battlements with his military engines, and sometimes advanced to the assault with a line of movable turrets on the backs of elephants. In the great cities of the East, the disadvantage of space, perhaps of position, was compensated by the zeal of the people, who seconded the garrison in the defence of their country and religion; and the fabulous promise of the Son of God, that Edessa should never be taken, filled the citizens with valiant confidence, and chilled the besiegers with doubt and dismay. The subordinate towns of Armenia and Mesopotamia were diligently strengthened, and the posts which appeared to have any command of ground or water were occupied by numerous forts, substantially built of stone, or more hastily erected with the obvious materials of earth and brick. The eye of Justinian investigated every spot; and his cruel precautions might attract the war into some lonely vale, whose peaceful natives, connected by trade and marriage, were ignorant of national discord and the quarrels of princes. Westward of the Euphrates, a sandy desert extends above six hundred miles to the Red Sea. Nature had interposed a vacant solitude between the ambition of two rival empires; the Arabians, till Mahomet arose, were formidable only as robbers; and in the proud security of peace the fortifications of Syria were neglected on the most vulnerable side. But the national enmity, at least the effects of that enmity, had been suspended by a truce, which continued above fourscore years. An ambassador from the emperor Zeno accompanied the rash and unfortunate Perozes, in his expedition against the Nepthalites, or white Huns, whose conquests had been stretched from the Caspian to the heart of India, whose throne was enriched with emeralds, and whose cavalry was supported by a line of two thousand elephants. The Persians were twice circumvented, in a situation which made valor useless and flight impossible; and the double victory of the Huns was achieved by military stratagem. They dismissed their royal captive after he had submitted to adore the majesty of a Barbarian; and the humiliation was poorly evaded by the casuistical subtlety of the Magi, who instructed Perozes to direct his attention to the rising sun. The indignant successor of Cyrus forgot his danger and his gratitude; he renewed the attack with headstrong fury, and lost both his army and his life. The death of Perozes abandoned Persia to her foreign and domestic enemies; and twelve years of confusion elapsed before his son Cabades, or Kobad, could embrace any designs of ambition or revenge. The unkind parsimony of Anastasius was the motive or pretence of a Roman war; the Huns and Arabs marched under the Persian standard, and the fortifications of Armenia and Mesopotamia were, at that time, in a ruinous or imperfect condition. The emperor returned his thanks to the governor and people of Martyropolis for the prompt surrender of a city which could not be
