The army proceeds through Arabia, having the Euphrates on the right. They suffer from want of provisions, and many of the beasts of burden perish; but supplies are procured from the opposite bank of the Euphrates. A dispute occurs between Clearchus and Menon, which is quelled by Cyrus. 1. Cyrus now advanced through Arabia, having the Euphrates on his right, five days' march through the desert, a distance of thirty-five parasangs. In this region the ground was entirely a plain, level as the sea. It was covered with wormwood, and whatever other kinds of shrub or reed grew on it, were all odoriferous as perfumes. But there were no trees. 2. There were wild animals, however, of various kinds; the most numerous were wild asses; there were also many ostriches, as well as bustards and antelopes; and these animals the horsemen of the army sometimes hunted. The wild asses, when any one pursued them, would start forward a considerable distance, and then stand still; (for they ran much more swiftly than the horse;) and again, when the horse approached, they did the same; and it was impossible to catch them, unless the horsemen, stationing themselves at intervals, kept up the pursuit with a succession of horses. The flesh of those that were taken resembled venison, but was more tender. 3. An ostrich no one succeeded in catching; and those horsemen who hunted that bird, soon desisted from the pursuit; for it far outstripped[44] them in its flight, using its feet for running, and its wings, raising them like a sail.[45] The bustards might be taken, if a person started them suddenly; for they fly but a short distance, like partridges, and soon tire. Their flesh was very delicious. 4. Marching through this region, they came to the river Mascas, the breadth of which is a plethrum. Here was a large deserted city, of which the name was Corsote, and which was entirely surrounded by the Mascas. Here they stayed three days, and furnished themselves with provisions. 5. Thence he proceeded, thirteen days' march through the desert, a distance of ninety parasangs, still keeping the Euphrates on the right, and arrived at a place called the Gates.[46] In this march many of the beasts of burden perished of hunger; for there was neither grass, nor any sort of tree, but the whole country was completely bare. The inhabitants, who quarried and fashioned millstones near the river, took them to Babylon, and sold them, and lived upon corn which they bought with the money. 6. Corn, too, failed the army, and it was not possible to buy any, except in the Lydian market among Cyrus's Barbarian troops, where they purchased a capithe[47] of wheat-flour or barley-meal for four sigli. The siglus is equivalent to seven Attic oboli and a half,[48] and the capithe contains two Attic chœnices. The soldiers therefore lived entirely upon flesh.
