Histories

As for the making of a king, they decided that he should be elected whose horse, after they were all in their saddles in the suburb of the city, should first be heard to neigh at sunrise.

Now Darius had a clever groom, whose name was Oebares. When the council broke up, Darius said to him: “Oebares, we have resolved to do as follows about the kingship: he shall be elected whose horse, after we are all mounted on our horses in the suburb of the city, neighs first at sunrise. Now if you have any cunning, figure out how we and no one else can win this prize.”
