the use of victory; by a march of forty-eight miles in four-and-twenty hours, his vanguard occupied the bridges of the great and the lesser Zab; and the cities and palaces of Assyria were open for the first time to the Romans. By a just gradation of magnificent scenes, they penetrated to the royal seat of Dastagerd, * and, though much of the treasure had been removed, and much had been expended, the remaining wealth appears to have exceeded their hopes, and even to have satiated their avarice. Whatever could not be easily transported, they consumed with fire, that Chosroes might feel the anguish of those wounds which he had so often inflicted on the provinces of the empire: and justice might allow the excuse, if the desolation had been confined to the works of regal luxury, if national hatred, military license, and religious zeal, had not wasted with equal rage the habitations and the temples of the guiltless subject. The recovery of three hundred Roman standards, and the deliverance of the numerous captives of Edessa and Alexandria, reflect a purer glory on the arms of Heraclius. From the palace of Dastagerd, he pursued his march within a few miles of Modain or Ctesiphon, till he was stopped, on the banks of the Arba, by the difficulty of the passage, the rigor of the season, and perhaps the fame of an impregnable capital. The return of the emperor is marked by the modern name of the city of Sherhzour: he fortunately passed Mount Zara, before the snow, which fell incessantly thirty-four days; and the citizens of Gandzca, or Tauris, were compelled to entertain the soldiers and their horses with a hospitable reception.

When the ambition of Chosroes was reduced to the defence of his hereditary kingdom, the love of glory, or even the sense of shame, should have urged him to meet his rival in the field. In the battle of Nineveh, his courage might have taught the Persians to vanquish, or he might have fallen with honor by the lance of a Roman emperor. The successor of Cyrus chose rather, at a secure distance, to expect the event, to assemble the relics of the defeat, and to retire, by measured steps, before the march of Heraclius, till he beheld with a sigh the once loved mansions of Dastagerd. Both his friends and enemies were persuaded, that it was the intention of Chosroes to bury himself under the ruins of the city and palace: and as both might have been equally adverse to his flight, the monarch of Asia, with Sira, * and three concubines, escaped through a hole in the wall nine days before the arrival of the Romans. The slow and stately procession in which he showed himself to the prostrate crowd, was changed to a rapid and secret journey; and the first evening he lodged in the cottage of a peasant, whose humble door would scarcely give admittance to the great king. His superstition was subdued by fear: on the third day, he entered with joy the fortifications of Ctesiphon; yet he still doubted of his safety till he had opposed the River Tigris to the pursuit of the Romans. The discovery of his flight agitated with terror and tumult the palace, the city, and the camp of Dastagerd: the satraps hesitated whether they had most to fear from their sovereign or the enemy; and the females of the harem were astonished and pleased by the sight of mankind, till the jealous husband of three thousand wives again confined them to a more distant castle. At his command, the army of Dastagerd retreated to a new camp: the front was covered by the Arba, and a line of two hundred elephants; the troops of the more distant provinces successively arrived, and the vilest domestics of the king and satraps were enrolled for the last defence of the throne. It was still in the power of Chosroes to obtain a reasonable peace; and he was repeatedly pressed by the messengers of Heraclius to spare the blood of his subjects, and to relieve a humane conqueror from the painful duty of carrying fire and sword through the fairest countries of Asia. But the pride of the Persian had not yet sunk to the level of his fortune; he derived a momentary confidence from the retreat of the emperor; he wept with impotent rage over the ruins of his Assyrian palaces, and disregarded too long the rising murmurs of the nation, who complained that their lives and fortunes were sacrificed to the obstinacy of an old man. That unhappy old man was himself tortured with the sharpest pains both of mind and body; and, in the consciousness of his approaching end, he resolved to fix the tiara on the head of Merdaza, the most favored of his sons. But the will of Chosroes was no longer revered, and Siroes, * who gloried in the rank and merit of his mother Sira, had conspired with the malecontents to assert and anticipate the rights of primogeniture. Twenty-two satraps (they styled themselves patriots) were tempted by the wealth and honors of a new reign: to the soldiers, the heir of Chosroes promised an increase of pay; to the Christians, the free exercise of their religion; to the captives, liberty and rewards; and to the nation, instant peace and the reduction of taxes. It was determined by the conspirators, that Siroes, with the ensigns of royalty, should appear in the camp; and if the enterprise should fail, his escape was contrived to the Imperial court. But the new monarch was saluted with unanimous acclamations; the flight of Chosroes (yet where could he have fled?) was rudely
