Paragraph 85 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.
Paragraph 86 86. Now at dawn of day the six came to the place as they had agreed, riding upon their horses; and as they rode through by the suburb of the city, when they came near the place where the mare had been tied up on the former night, the horse of Dareios ran up to the place and neighed; and just when the horse had done this, there came lightning and thunder from a clear sky: and the happening of these things to Dareios consummated his claim, for they seemed to have come to pass by some design, and the others leapt down from their horses and did obeisance to Dareios.
Paragraph 87 87. Some say that the contrivance of Oibares was this, but others say as follows (for the story is told by the Persians in both ways), namely that he touched with his hands the parts of this mare and kept his hand hidden in his trousers; and when at sunrise they were about to let the horses go, this Oibares pulled out his hand and applied it to the nostrils of the horse of Dareios; and the horse, perceiving the smell, snorted and neighed.
