While Crassus was still considering, and as yet undetermined, there came to the camp an Arab chief named Ariamnes, a cunning and wily fellow, who, of all the evil chances which combined to lead them on to destruction, was the chief and the most fatal. Some of Pompey's old soldiers knew him, and remembered him to have received some kindnesses of Pompey, and to have been looked upon as a friend to the Romans, but he was now suborned by the king's generals, and sent to Crassus to entice him if possible from the river and hills into the wide open plain, where he might be surrounded. For the Parthians desired anything rather than to be obliged to meet the Romans face to face. He, therefore, coming to Crassus (and he had a persuasive tongue), highly commended Pompey as his benefactor, and admired the forces that Crassus had with him, but seemed to wonder why he delayed and made preparations, as if he should not use his feet more than any arms, against men that, taking with them their best goods and chattels, had designed long ago to fly for refuge to the Scythians or Hyrcanians. "If you meant to fight, you should have made all possible haste, before the king should recover courage, and collect his forces together; at present you see Surena and Sillaces opposed to you, to draw you off in pursuit of them, while the king himself keeps out of the way." But this was all a lie, for Hyrodes had divided his army in two parts; with one he in person wasted Armenia, revenging himself upon Artavasdes, and sent Surena against the Romans, not out of contempt, as some pretend, for there is no likelihood that he should despise Crassus, one of the chiefest men of Rome, to go and fight with Artavasdes, and invade Armenia; but much more probably he really apprehended the danger, and therefore waited to see the event, intending that Surena should first run the hazard of a battle, and draw the enemy on. Nor was this Surena an ordinary person, but in wealth, family, and reputation, the second man in the kingdom, and in courage and prowess the first, and for bodily stature and beauty no man like him. Whenever he travelled privately, he had one thousand camels to carry his baggage, two hundred chariots for his concubines, one thousand completely armed men for life-guards, and a great many more light-armed; and he had at least ten thousand horsemen altogether, of his servants and retinue. The honour had long belonged to his family, that at the king's coronation he put the crown upon his head, and when this very king Hyrodes had been exiled, he brought him in; it was he, also, that took the great city of Seleucia, was the first man that scaled the walls, and with his own hand beat off the defenders. And though at this time he was not above thirty years old, he had a great name for wisdom and sagacity, and, indeed, by these qualities chiefly, he overthrew Crassus, who first through his overweening confidence, and afterwards because he was cowed by his calamities, fell a ready victim to his subtlety. When Ariamnes had thus worked upon him, he drew him from the river into vast plains, by a way that at first was pleasant and easy but afterwards very troublesome by reason of the depth of the sand; no tree, nor any water, and no end of this to be seen; so that they were not only spent with thirst, and the difficulty of the passage, but were dismayed with the uncomfortable prospect of not a bough, not a stream, not a hillock, not a green herb, but in fact a sea of sand, which encompassed the army with its waves. They began to suspect some treachery, and at the same time came messengers from Artavasdes, that he was fiercely attacked by Hyrodes, who had invaded his country, so that now it was impossible for him to send any succours, and that he therefore advised Crassus to turn back, and with joint forces to give Hyrodes battle, or at least that he should march and encamp where horses could not easily come, and keep to the mountains. Crassus, out of anger and perverseness, wrote him no answer, but told them, at present he was not at leisure to mind the Armenians, but he would call upon them another time, and revenge himself upon Artavasdes for his treachery. Cassius and his friends began again to complain, but when they perceived that it merely displeased Crassus, they gave over, but privately railed at the barbarian, "What evil genius, O thou worst of men, brought thee to our camp, and with what charms and potions hast thou bewitched Crassus, that he should march his army through a vast and deep desert, through ways which are rather fit for a captain of Arabian robbers, than for the general of a Roman army?" But the barbarian, being a wily fellow, very submissively exhorted them, and encouraged them to sustain it a little further, and ran about the camp, and professing to cheer up the soldiers, asked them, jokingly, "What, do you think you march through Campania, expecting everywhere to find springs, and shady trees, and baths, and inns of entertainment? Consider you now travel through the confines of Arabia and Assyria." Thus he managed them like children, and before the cheat was discovered, he rode away;not but that Crassus was aware of his going, but he had persuaded him that he would go and contrive how to disorder the affairs of the enemy.
It is related that Crassus came abroad that day not in his scarlet robe, which Roman generals usually wear, but in a black one, which, as soon as he perceived, he changed. And the standard-bearers had much ado to take up their eagles, which seemed to be fixed to the place.
