Xenophon Cyropaedia 4.3

[1]
  Now a part of the Medes were already bringing ¹ in the wagons which had been hurried forward and which they had overtaken and turned back packed full of what an army needs; others were bringing in the carriages that conveyed the most high-born women, not only wedded wives but also concubines, who on account of their beauty had been brought along; these also they captured and brought in.

[2]
  For even unto this day all who go to war in Asia take with them to the field what they prize most highly; for they say that they would do battle the more valiantly, if all that they hold dearest were there; for these, they say, they must do their best to protect. This may, perhaps, be true; but perhaps also they follow this custom for their own sensual gratification.

[3]
  When Cyrus saw what the Medes and Hyrcanians were doing, he poured reproach, as it were, upon himself and his men, because during this time the others seemed to be surpassing them in strenuous activity and gaining something by it, too, while he and his men remained in a position where there was little or nothing to do. And it did seem so; for when the horsemen brought in and showed to Cyrus what they brought, they rode away again in pursuit of the others; for, they said, they had been instructed by their officers so to do.
  Though Cyrus was naturally nettled at this, still he assigned a place to the spoil. And again he called his captains together and standing where they would all be sure to hear his words of counsel, he spoke as follows:

[4] Friends, we all appreciate, I am sure, that if we could but make our own the good fortune that is now dawning upon us, great blessings would come to all the Persians and above all, as is reasonable, to us by whom they are secured. But I fail to see how we are to establish a valid claim to the spoil if we cannot gain it by ² our own strength; and this we cannot do, unless the Persians have cavalry of their own.

[5] Just think of it, he went on; we Persians have arms with which, it seems, we go into close quarters and put the enemy to flight; and then when we have routed them, how could we without horses capture or kill horsemen or bowmen or targeteers in their flight? And what bowmen or spearmen or horsemen would be afraid to come up and inflict loss upon us, when they are perfectly sure that they are in no more danger of being harmed by us than by the trees growing yonder?

[6] And if this is so, is it not evident that the horsemen who are now with us consider that everything that has fallen into our hands is theirs no less than ours, and perhaps, by Zeus, even more so?

[7] As things are now, therefore, this is necessarily the case. But suppose we acquired a body of cavalry not inferior to theirs, is it not patent to us all that we should be able even without them to do to the enemy what we are now doing with their aid, and that we should find them then less presumptuous toward us? For whenever they chose to remain or to go away, we should care less, if we were sufficient unto ourselves without them. Well and good.

[8] No one, I think, would gain-say ³ me in this statement, that it makes all the difference in the world whether the Persians have their own cavalry or not. But perhaps you are wondering how this may be accomplished. Well then, supposing that we wished to organize a division of cavalry, had we not better consider our resources and our deficiencies?

[9] Here, then, in camp are numbers of horses which we have taken and reins which they obey, and everything else that horses must have before you can use them. Yes, and more, all that a horseman must use we have—breastplates as defensive armour for the body and spears which we may use either to hurl or to thrust.

[10] What then remains? Obviously we must have men. Now these above all other things we have; for nothing is so fully ours as we ourselves are our own.
  But perhaps some one will say that we do not know how to ride. No, by Zeus; and no one of these who now know how to ride did know before he learned. But, some one may say, they learned when they were boys.

[11] And are boys more clever in learning what is explained to them and what is shown them than are men? And which are better able with bodily strength to put into practice what they have learned, boys or men?

[12] Again, we have more time for learning than either boys or other men; for we have not, like boys, to learn to shoot, for we know how already; or to throw the spear, for we understand that, too. No; nor yet again are we so situated as other men, some of whom are kept busy with their farming, some with their trades, and some with other domestic labours, while we not only have time for military operations, but they are forced upon us.

[13] And this is not like many other branches of military discipline, useful but laborious; nay, when it comes to marching, is not riding more pleasant than tramping along on one’s own two feet? And when speed is required, is it not delightful quickly to reach a friend’s side, if need be, and quickly to overtake a man or an animal, if occasion should require one to give chase? And is this not convenient, that the horse should help you to carry whatever accoutrement you must take along? Surely, to have and to carry are not quite the same thing.

[14]
  What one might have most of all to fear, however, is that in case it is necessary for us to go into action on horseback before we have thoroughly mastered this task, we shall then be no longer infantrymen and not yet competent cavalrymen. But not even this is an insurmountable difficulty; for whenever we wish, we may at once fight on foot; for in learning to ride we shall not be unlearning any of our infantry tactics.

[15]
  Thus Cyrus spoke; and Chrysantas seconded ⁴ him in the following speech: I, for one, am so eager to learn horsemanship, that I think that if I become a horseman I shall be a man on wings.

[16] For as we are now, I, at least, am satisfied, when I have an even start in running a race with any man, if I can beat him only by a head; and when I see an animal running along, I am satisfied if I can get a good aim quickly enough to shoot him or spear him before he gets very far away. But if I become a horseman I shall be able to overtake a man though he is as far off as I can see him; and I shall be able to pursue animals and overtake them and either strike them down from close at hand or spear them as if they were standing still; and they seem so, for though both be moving rapidly, yet, if they are near to one another, they are as if standing still.

[17]
  Now the creature that I have envied most is, I think, the Centaur (if any such being ever existed), able to reason with a man’s intelligence and to manufacture with his hands what he needed, while he possessed the fleetness and strength of a horse so as to overtake whatever ran before him and to knock down whatever stood in his way. Well, all his advantages I combine in myself by becoming a horseman.

[18] At any rate, I shall be able to take forethought for everything with my human mind, I shall carry my weapons with my hands, I shall pursue with my horse and overthrow my opponent by the rush of my steed, but I shall not be bound fast to him in one growth, like the Centaurs.

[19] Indeed, my state will be better than being grown together in one piece; for, in my opinion at least, the Centaurs must have had difficulty in making use of many of the good things invented for man; and how could they have enjoyed many of the comforts natural to the horse?

[20] But if I learn to ride, I shall, when I am on horseback, do everything as the Centaur does, of course; but when I dismount, I shall dine and dress myself and sleep like other human beings; and so what else shall I be than a Centaur that can be taken apart and put together again?

[21]
  And then, he added, I shall have the advantage of the Centaur in this, too, that he used to see with but two eyes and hear with but two ears, while I shall gather evidence with four eyes and learn through four ears; for they say that a horse actually sees many things with his eyes before his rider does and makes them known to him, and that he hears many things with his ears before his rider does and gives him intimation of them. Put me down, therefore, said he, as one of those who are more than eager to become cavalrymen.
  Aye, by Zeus, said all the rest, and us too.

[22]
  How would it do, then, Cyrus asked, since ⁵ we are all so very well agreed upon this matter, if we should make a rule for ourselves that it be considered improper for any one of us whom I provide with a horse to be seen going anywhere on foot, whether the distance he has to go be long or short, so that people may think that we are really Centaurs?

[23]
  He put the question thus and they all voted aye. And so from that time even to this day, the Persians follow that practice, and no Persian gentleman would be seen going anywhere on foot, if he could help it.
  Such were their discussions on this occasion.
