10. Hence they proceeded one day's journey, six parasangs, to a large unoccupied fortress,[152] situated near a city, the name of which was Mespila; the Medes had formerly inhabited it. The foundation of the wall was of polished stone, full of shells,[153] the breadth fifty feet, and the height fifty; 11. and on it was constructed a wall of bricks, fifty feet broad, and a hundred high; the circumference of it was six parasangs. Here Medea, the king's wife, is said to have taken refuge, when the Medes were deprived of their empire by the Persians. 12. The king of the Persians, on besieging this city, was unable to reduce it either by length of time or by assault, but Jupiter, as with a thunder-stroke,[154] deprived the inhabitants of their senses, and thus it was taken. 13. Hence they proceeded one day's journey, a distance of four parasangs. In the course of this day's march Tissaphernes made his appearance, having with him the cavalry which he himself commanded, the force of Orontes, who had married the king's daughter, the Barbarian troops with which Cyrus went up, the troops with which the king's brother came to assist him, and, besides these, all that the king himself had given him; so that his army appeared extremely numerous. 14. When he came near, he stationed some of his companies in the rear, and brought others round upon our flanks, but did not venture to make a charge, or show any disposition to endanger himself, but ordered his men to use their slings and bows. 15. But when the Rhodians, who were dispersed among the ranks, began to use their slings, and the Scythian archers[155] discharged their arrows, no one failing to hit a man, (for it would not have been easy to do so, even if they had been ever so desirous,) Tissaphernes hastily retreated beyond reach of the missiles, and the other divisions drew off at the same time. 16. During the rest of the day the Greeks continued their march, and the enemy followed; but the Barbarians no longer harassed them with their usual skirmishing; for the Rhodians sent their missiles to a greater distance than the Persians, and than most of the bowmen. 17. The bows of the Persians, too, were large, so that such of their arrows as were taken up, were of service to the Cretans, who continued to use the enemy's arrows, and practised shooting by sending them far up into the air.[156] A great number of bowstrings were also found in the villages, and some lead, so that they could use it for their slings.
