98. And when they straightway proposed the question whom they should set up to be king, Deïokes was much put forward and commended by every one, until at last they agreed that he should be their king. And he bade them build for him a palace worthy of the royal dignity and strengthen him with a guard of spearmen. And the Medes did so: for they built him a large and strong palace in that part of the land which he told them, and they allowed him to select spearmen from all the Medes. And when he had obtained the rule over them, he compelled the Medes to make one fortified city and pay chief attention to this, having less regard to the other cities. And as the Medes obeyed him in this also, he built large and strong walls, those which are now called Agbatana, standing in circles one within the other. And this wall is so contrived that one circle is higher than the next by the height of the battlements alone. And to some extent, I suppose, the nature of the ground, seeing that it is on a hill, assists towards this end; but much more was it produced by art, since the circles are in all seven in number. 111 And within the last circle are the royal palace and the treasure-houses. The largest of these walls is in size about equal to the circuit of the wall round Athens; and of the first circle the battlements are white, of the second black, of the third crimson, of the fourth blue, of the fifth red: thus are the battlements of all the circles coloured with various tints, and the two last have their battlements one of them overlaid with silver and the other with gold. 99. These walls then Deïokes built for himself and round his own palace, and the people he commanded to dwell round about the wall. And after all was built, Deïokes established the rule, which he was the first to establish, ordaining that none should enter into the presence of the king, but that they deal with him always through messengers; and that the king should be seen by no one; and moreover that to laugh or to spit in presence is unseemly, and this last for every one without exception. 112 Now he surrounded himself with this state 113 to the end that his fellows, who had been brought up with him and were of no meaner family nor behind him in manly virtue, might not be grieved by seeing him and make plots against him, but that being unseen by them he might be thought to be of different mould. 100. Having set these things in order and strengthened himself in his despotism, he was severe in preserving justice; and the people used to write down their causes and send them in to his presence, and he determined the questions which were brought in to him and sent them out again. Thus he used to do about the judgment of causes; and he also took order for this, that is to say, if he heard that any one was behaving in an unruly manner, he sent for him and punished him according as each act of wrong deserved, and he had watchers and listeners about all the land over which he ruled.
