So when Otanes, who was desirous to give equality to the Persians, found his opinion defeated, he spoke to those assembled thus: "Partisans, it is clear that some one of us must become king, selected either by casting lots, or by entrusting the decision to the multitude of the Persians and taking him whom it shall choose, or by some other means. I therefore shall not be a competitor with you, for I do not desire either to rule or to be ruled; and on this condition I withdraw from my claim to rule, namely that I shall not be ruled by any of you, either I myself or my descendants in future time." When he had said this, the six made agreement with him on those terms, and he was no longer a competitor with them, but withdrew from the assembly; and at the present time this house remains free alone of all the Persian houses, and submits to rule only so far as it wills to do so itself, not transgressing the laws of the Persians.
84. The rest however of the seven continued to deliberate how they should establish a king in the most just manner; and it was resolved by them that to Otanes and his descendants in succession, if the kingdom should come to any other of the seven, there should be given as special gifts a Median dress every year and all those presents which are esteemed among the Persians to be the most valuable: and the reason why they determined that these things should be given to him, was because he first suggested to them the matter and combined them together. These were special gifts for Otanes; and this they also determined for all in common, namely that any one of the seven who wished might pass in to the royal palaces without any to bear in a message, unless the king happened to be sleeping with his wife; and that it should not be lawful for the king to marry from any other family, but only from those of the men who had made insurrection with him: and about the kingdom they determined this, namely that the man whose horse should first neigh at sunrise in the suburb of the city when they were mounted upon their horses, he should have the kingdom.
85. Now Dareios had a clever horse-keeper, whose name was Oibares. To this man, when they had left their assembly, Dareios spoke these words: "Oibares, we have resolved to do about the kingdom thus, namely that the man whose horse first neighs at sunrise, when we are mounted upon our horses he shall be king. Now therefore, if thou hast any cleverness, contrive that we may obtain this prize, and not any other man." Oibares replied thus: "If, my master, it depends in truth upon this whether thou be king or no, have confidence so far as concerns this and keep a good heart, for none other shall be king before thee; such charms have I at my command." Then Dareios said: "If then thou hast any such trick, it is time to devise it and not to put things off, for our trial is to-morrow." Oibares therefore hearing this did as follows:—when night was coming on he took one of the mares, namely that one which the horse of Dareios preferred, and this he led into the suburb of the city and tied her up: then he brought to her the horse of Dareios, and having for some time led him round her, making him go so close by so as to touch the mare, at last he let the horse mount.
