by its repeated strokes, they were torn with long iron hooks from the wall. From those walls, a shower of darts was incessantly poured on the heads of the assailants, but they were most dangerously annoyed by a fiery composition of sulphur and bitumen, which in Colchos might with some propriety be named the oil of Medea. Of six thousand Romans who mounted the scaling-ladders, their general, Bessas, was the first, a gallant veteran of seventy years of age; the courage of their leader, his fall, and extreme danger, animated the irresistible effort of his troops; and their prevailing numbers oppressed the strength, without subduing the spirit, of the Persian garrison. The fate of these valiant men deserves to be more distinctly noticed. Seven hundred had perished in the siege, two thousand three hundred survived to defend the breach. One thousand and seventy were destroyed with fire and sword in the last assault: and, if seven hundred and thirty were made prisoners, only eighteen among them were found without the marks of honourable wounds. The remaining five hundred escaped into the citadel, which they maintained without any hopes of relief, rejecting the fairest terms of capitulation and service, till they were lost in the flames. They died in obedience to the commands of their prince; and such examples of loyalty and valour might excite their countrymen to deeds of equal despair and more prosperous event. The instant demolition of the works of Petra confessed the astonishment and apprehension of the conqueror.
The Colchian or Lazic war. A.D. 549-556 A Spartan would have praised and pitied the virtue of these heroic slaves; but the tedious warfare and alternate success of the Roman and Persian arms cannot detain the attention of posterity at the foot of mount Caucasus. The advantages obtained by the troops of Justinian were more frequent and splendid; but the forces of the great king were continually supplied, till they amounted to eight elephants and seventy thousand men, including twelve thousand Scythian allies, and above three thousand Dilemites, who descended by their free choice from the hills of Hyrcania, and were equally formidable in close or in distant combat. The siege of Archæopolis, a name imposed or corrupted by the Greeks, was raised with some loss and precipitation; but the Persians occupied the passes of Iberia; Colchos was enslaved by their forts and garrisons; they devoured the scanty sustenance of the people; and the prince of the Lazi fled into the mountains. In the Roman camp, faith and discipline were unknown; and the
