While Xerxes did thus, he sent a messenger to Iran [53,32] (nation), AsiaPersia with news of his present misfortune. Now there is nothing mortal that accomplishes a course more swiftly than do these messengers, by the Persians' skillful contrivance. It is said that as many days as there are in the whole journey, so many are the men and horses that stand along the road, each horse and man at the interval of a day's journey. These are stopped neither by snow nor rain nor heat nor darkness from accomplishing their appointed course with all speed.

The first rider delivers his charge to the second, the second to the third, and thence it passes on from hand to hand, even as in the Greek torch-bearers' race in honor of Hephaestus. This riding-post is called in Iran [53,32] (nation), AsiaPersia, angareion.
