After this when Skyles was riding out again to his own abode, the Scythians took his brother Octamasades for their leader, who was a son of the daughter of Teres, and made insurrection against Skyles. He then when he perceived that which was being done to his hurt and for what reason it was being done, fled for refuge to Thrace; and Octamasades being informed of this, proceeded to march upon Thrace. So when he had arrived at the river Ister, the Thracians met him; and as they were about to engage battle, Sitalkes sent a messenger to Octamasades and said: "Why must we make trial of one another in fight? Thou art my sister's son and thou hast in thy power my brother. Do thou give him back to me, and I will deliver to thee thy brother Skyles: and let us not either of us set our armies in peril, either thou or I." Thus Sitalkes proposed to him by a herald; for there was with Octamasades a brother of Sitalkes, who had gone into exile for fear of him. And Octamasades agreed to this, and by giving up his own mother's brother to Sitalkes he received his brother Skyles in exchange: and Sitalkes when he received his brother led him away as a prisoner, but Octamasades cut off the head of Skyles there upon the spot. Thus do the Scythians carefully guard their own customary observances, and such are the penalties which they inflict upon those who acquire foreign customs besides their own.
81. How many the Scythians are I was not able to ascertain precisely, but I heard various reports of the number: for reports say both that they are very many in number and also that they are few, at least as regards the true Scythians. 81 Thus far however they gave me evidence of my own eyesight:—there is between the river Borysthenes and the Hypanis a place called Exampaios, of which also I made mention somewhat before this, saying that there was in it a spring of bitter water, from which the water flows and makes the river Hypanis unfit to drink. In this place there is set a bronze bowl, in size at least six times as large as the mixing-bowl at the entrance of the Pontus, which Pausanias the son of Cleombrotos dedicated: and for him who has never seen that, I will make the matter clear by saying that the bowl in Scythia holds easily six hundred amphors, 82 and the thickness of this Scythian bowl is six fingers. This then the natives of the place told me had been made of arrow-heads: for their king, they said, whose name was Ariantas, wishing to know how many the Scythians were, ordered all the Scythians to bring one arrow-head, each from his own arrow, and whosoever should not bring one, he threatened with death. So a great multitude of arrow-heads was brought, and he resolved to make of them a memorial and to leave it behind him: from these then, they said, he made this bronze bowl and dedicated it in this place Exampaios.
