The third river is the Hypanis; this comes from Scythia, flowing out of a great lake, around which wild, white horses graze. This lake is truly called the mother of the Hypanis. Here, then, the Hypanis rises; for five days' journey its waters are shallow and still sweet; after that for four days' journey seaward it is amazingly bitter, for a spring runs into it so bitter that although its volume is small its admixture taints the Hypanis, one of the few great rivers of the world. This spring is on the border between the farming Scythians and the Alazones; the name of it and of the place where it rises is in Scythian Exampaeus; in the Greek tongue, Sacred Ways. The Tyras and the Hypanis draw near together in the Alazones' country; after that they flow apart, the intervening space growing wider.
