29. Thus he said; and Xerxes was pleased by the things which he had spoken, and replied: "Lydian host, ever since I went forth from the Persian land I have encountered no man up to this time who was desirous to entertain my army, or who came into my presence and made offer of his own free will to contribute money to me for the war, except only thee: and thou not only didst entertain my army magnificently, but also now dost make offer of great sums of money. To thee therefore in return I give these rewards,--I make thee my guest-friend, and I will complete for thee the four hundred myriads of staters by giving from myself the seven thousand, in order that thy four hundred myriads may not fall short by seven thousand, but thou mayest have a full sum in thy reckoning, completed thus by me. Keep possession of that which thou hast got for thyself, and be sure to act always thus; for if thou doest so, thou wilt have no cause to repent either at the time or afterwards." 30. Having thus said and having accomplished his promise, he continued his march onwards; and passing by a city of the Phrygians called Anaua and a lake whence salt is obtained, he came to Colossai, a great city of Phrygia, where the river Lycos falls into an opening of the earth and disappears from view, and then after an interval of about five furlongs it comes up to view again, and this river also flows into the Maiander. Setting forth from Colossai towards the boundaries of the Phrygians and Lydians, the army arrived at the city of Kydrara, where a pillar 3001 is fixed, set up by Croesus, which declares by an inscription that the boundaries are there. 31. From Phrygia then he entered Lydia; and here the road parts into two, and that which goes to the left leads towards Caria, while that which goes to the right leads to Sardis; and travelling by this latter road one must needs cross the river Maiander and pass by the city of Callatebos, where men live whose trade it is to make honey of the tamarisk-tree and of wheat-flour. By this road went Xerxes and found a plane-tree, to which for its beauty he gave an adornment of gold, and appointed that some one should have charge of it always in undying succession; 31 and on the next day he came to the city of the Lydians. 32. Having come to Sardis he proceeded first to send heralds to Hellas, to ask for earth and water, and also to give notice beforehand to prepare meals for the king; except that he sent neither to Athens nor Lacedemon to ask for earth, but to all the other States: and the reason why he sent the second time to ask for earth and water was this,--as many as had not given at the former time to Dareios when he sent, these he thought would certainly give now by reason of their fear: this matter it was about which he desired to have certain knowledge, and he sent accordingly.
