The Histories · 4.126

Now as this went on for a long time and did not cease, Dareios sent a horseman to Idanthyrsos king of the Scythians and said as follows: "Thou most wondrous man, why dost thou fly for ever, when thou mightest do of these two things one?—if thou thinkest thyself able to make opposition to my power, stand thou still and cease from wandering abroad, and fight; but if thou dost acknowledge thyself too weak, cease then in that case also from thy course, and come to speech with thy master, bringing to him gifts of earth and water."
