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.
