777 from that of the Matienians), and the fourth of the rivers is called Gyndes, the same which once Cyrus divided into three hundred and sixty channels. 778 Passing thence into the Kissian land, there are eleven stages, forty-two and a half leagues, to the river Choaspes, which is also a navigable stream; and upon this is built the city of Susa. The number of these stages amounts in all to one hundred and eleven. 53. This is the number of stages with resting-places, as one goes up from Sardis to Susa: and if the royal road has been rightly measured as regards leagues, and if the league 779 is equal to thirty furlongs, 780 (as undoubtedly it is), the number of furlongs from Sardis to that which is called the palace of Memnon is thirteen thousand five hundred, the number of leagues being four hundred and fifty. So if one travels a hundred and fifty furlongs each day, just ninety days are spent on the journey.
