Borysthenes
The Scythian river god of Borysthenes, now called the Dneiper, which flows south across the steppe into the Black Sea.
A daughter of Borysthenes, by Zeus, produced a son, Targitaus who was believed to be the ancestor of all the Scythians. (Herodotus The History. The Fourth Book: Melpomene)
From Herodotus The History. The Fourth Book: Melpomene
According to the account which the Scythians themselves give, they are the youngest of all nations. Their tradition is as follows. A certain Targitaus was the first man who ever lived in their country, which before his time was a desert without inhabitants. He was a child—I do not believe the tale, but it is told nevertheless—of Jove and a daughter of the Borysthenes. Targitaus, thus descended, begat three sons, Leipoxais, Arpoxais, and Colaxais, who was the youngest born of the three. While they still ruled the land, there fell from the sky four implements, all of gold—a plough, a yoke, a battle-axe, and a drinking-cup. The eldest of the brothers perceived them first, and approached to pick them up; when lo! as he came near, the gold took fire, and blazed. He therefore went his way, and the second coming forward made the attempt, but the same thing happened again. The gold rejected both the eldest and the second brother. Last of all the youngest brother approached, and immediately the flames were extinguished; so he picked up the gold, and carried it to his home. Then the two elder agreed together, and made the whole kingdom over to the youngest born.

From Smith's Dictionary of Greek and Roman Biography and MythologyThe fourth of the Scythian rivers is the Borysthenes. Next to the Ister, it is the greatest of them all; and, in my judgment, it is the most productive river, not merely in Scythia, but in the whole world, excepting only the Nile, with which no stream can possibly compare. It has upon its banks the loveliest and most excellent pasturages for cattle; it contains abundance of the most delicious fish; its water is most pleasant to the taste; its stream is limpid, while all the other rivers near it are muddy; the richest harvests spring up along its course, and where the ground is not sown, the heaviest crops of grass; while salt forms in great plenty about its mouth without human aid, and large fish are taken in it of the sort called Antacaei, without any prickly bones, and good for pickling. Nor are these the whole of its marvels. As far inland as the place named Gerrhus, which is distant forty days’ voyage from the sea, its course is known, and its direction is from north to south; but above this no one has traced it, so as to say through what countries it flows. It enters the territory of the Scythian Husbandmen after running for some time across a desert region, and continues for ten days’ navigation to pass through the land which they inhabit. It is the only river besides the Nile the sources of which are unknown to me, as they are also (I believe) to all the other Greeks. Not long before it reaches the sea, the Borysthenes is joined by the Hypanis, which pours its waters into the same lake. The land that lies between them, a narrow point like the beak of a ship, is called Cape Hippolaus. Here is a temple dedicated to Ceres, and opposite the temple upon the Hypanis is the dwelling-place of the Borysthenites. But enough has been said of these streams.
