informed the senate of Constantinople of his safety and success, which they had already felt by the retreat of the besiegers. The bridges of the Euphrates were destroyed by the Persians; but as soon as the emperor had discovered a ford, they hastily retired to defend the banks of the Sarus, in Cilicia. That river, an impetuous torrent, was about three hundred feet broad; the bridge was fortified with strong turrets; and the banks were lined with Barbarian archers. After a bloody conflict, which continued till the evening, the Romans prevailed in the assault; and a Persian of gigantic size was slain and thrown into the Sarus by the hand of the emperor himself. The enemies were dispersed and dismayed; Heraclius pursued his march to Sebaste in Cappadocia; and at the expiration of three years, the same coast of the Euxine applauded his return from a long and victorious expedition.

Instead of skirmishing on the frontier, the two monarchs who disputed the empire of the East aimed their desperate strokes at the heart of their rival. The military force of Persia was wasted by the marches and combats of twenty years, and many of the veterans, who had survived the perils of the sword and the climate, were still detained in the fortresses of Egypt and Syria. But the revenge and ambition of Chosroes exhausted his kingdom; and the new levies of subjects, strangers, and slaves, were divided into three formidable bodies. The first army of fifty thousand men, illustrious by the ornament and title of the golden spears, was destined to march against Heraclius; the second was stationed to prevent his junction with the troops of his brother Theodore's; and the third was commanded to besiege Constantinople, and to second the operations of the chagan, with whom the Persian king had ratified a treaty of alliance and partition. Sarbar, the general of the third army, penetrated through the provinces of Asia to the well- known camp of Chalcedon, and amused himself with the destruction of the sacred and profane buildings of the Asiatic suburbs, while he impatiently waited the arrival of his Scythian friends on the opposite side of the Bosphorus. On the twenty-ninth of June, thirty thousand Barbarians, the vanguard of the Avars, forced the long wall, and drove into the capital a promiscuous crowd of peasants, citizens, and soldiers. Fourscore thousand of his native subjects, and of the vassal tribes of Gepidæ, Russians, Bulgarians, and Sclavonians, advanced under the standard of the chagan; a month was spent in marches and negotiations, but the whole city was invested on the thirty-first of July, from the suburbs of Pera and Galata to the Blachernæ and seven towers; and the inhabitants descried with terror the flaming signals of the European and Asiatic shores. In the mean while, the magistrates of Constantinople repeatedly strove to purchase the retreat of the chagan; but their deputies were rejected and insulted; and he suffered the patricians to stand before his throne, while the Persian envoys, in silk robes, were seated by his side. "You see," said the haughty Barbarian, "the proofs of my perfect union with the great king; and his lieutenant is ready to send into my camp a select band of three thousand warriors. Presume no longer to tempt your master with a partial and inadequate ransom your wealth and your city are the only presents worthy of my acceptance. For yourselves, I shall permit you to depart, each with an under-garment and a shirt; and, at my entreaty, my friend Sarbar will not refuse a passage through his lines. Your absent prince, even now a captive or a fugitive, has left Constantinople to its fate; nor can you escape the arms of the Avars and Persians, unless you could soar into the air like birds, unless like fishes you could dive into the waves." During ten successive days, the capital was assaulted by the Avars, who had made some progress in the science of attack; they advanced to sap or batter the wall, under the cover of the impenetrable tortoise; their engines discharged a perpetual volley of stones and darts; and twelve lofty towers of wood exalted the combatants to the height of the neighboring ramparts. But the senate and people were animated by the spirit of Heraclius, who had detached to their relief a body of twelve thousand cuirassiers; the powers of fire and mechanics were used with superior art and success in the defence of Constantinople; and the galleys, with two and three ranks of oars, commanded the Bosphorus, and rendered the Persians the idle spectators of the defeat of their allies. The Avars were repulsed; a fleet of Sclavonian canoes was destroyed in the harbor; the vassals of the chagan threatened to desert, his provisions were exhausted, and after burning his engines, he gave the signal of a slow and formidable retreat. The devotion of the Romans ascribed this signal deliverance to the Virgin Mary; but the mother of Christ would surely have condemned their inhuman murder of the Persian envoys, who were entitled to the rights of humanity, if they were not protected by the laws of nations.

After the division of his army, Heraclius prudently retired to the banks of the Phasis, from whence he maintained a defensive war against the fifty thousand gold spears of Persia. His anxiety was relieved by
