10. Accordingly, having advanced seventy furlongs with very scanty supplies, the herbage and the corn being all burnt, each man saved for himself just as much of the grain or forage as he could snatch from the flames and carry.
11. And having left this spot, when the army had arrived at the district called Maranx, near daybreak an immense multitude of Persians appeared, with Merenes, the captain of their cavalry, and two sons of the king, and many nobles.
12. All the troops were clothed in steel, in such a way that their bodies were covered with strong plates, so that the hard joints of the armour fitted every limb of their bodies; and on their heads were effigies of human faces so accurately fitted, that their whole persons being covered with metal, the only place where any missiles which fell upon them could stick, was either where there were minute openings to allow of the sight of the eyes penetrating, or where holes for breathing were left at the extremities of the nostrils.
13. Part of them who were prepared to fight with pikes stood immovable, so that you might have fancied they were held in their places by fastenings of brass; and next to them the archers (in which art that nation has always been most skilful from the cradle) bent their supple bows with widely extended arms, so that the strings touched their right breasts, while the arrows lay just upon their left hands; and the whistling arrows flew, let loose with great skill of finger, bearing deadly wounds.
14. Behind them stood the glittering elephants in formidable array, whose grim looks our terrified men could hardly endure; while the horses were still more alarmed at their growl, odour, and unwonted aspect.
15. Their drivers rode on them, and bore knives with handles fastened to their right hands, remembering the disaster which they had experienced at Nisibis; and if the ferocious animal overpowered his overseer, they pierced the spine where the head is joined to the neck with a vigorous blow, that the beast might not recoil upon their own ranks, as had happened on that occasion, and trample down their own people; for it was found out by Hasdrubal, the brother of Hannibal, that in this way these animals might be very easily deprived of life.
16. The sight of these beasts caused great alarm; and so this most intrepid emperor, attended with a strong body of his armed cohorts and many of his chief officers, as the crisis and the superior numbers of the enemy required, marshalled his troops in the form of a crescent with the wings bending inwards to encounter the enemy.
17. And to hinder the onset of the archers from disordering our columns, by advancing with great speed he baffled the aim of their arrows; and after he had given the formal signal for fighting, the Roman infantry, in close order, beat back the front of the enemy with a vigorous effort.
18. The struggle was fierce, and the clashing of the shields, the din of the men, and the doleful whistle of the javelins, which continued without intermission, covered the plains with blood and corpses, the Persians falling in every direction; and though they were often slack in fighting, being accustomed chiefly to combat at a distance by means of missiles, still now foot to foot they made a stout resistance; and when they found any of their divisions giving way, they retreated like rain before the wind, still with showers of arrows seeking to deter their foes from pursuing them. So the Parthians were defeated by prodigious efforts, till our soldiers, exhausted by the heat of the day, on the signal for retreat being sounded, returned to their camp, encouraged for the future to greater deeds of daring.
19. In this battle, as I have said, the loss of the Persians was very great—ours was very slight. But the most important death in our ranks was that of Vetranio, a gallant soldier who commanded the legion of Zianni.[152]
