Now the Tearos is said by those who dwell near it to be the best of all rivers, both in other respects which tend to healing and especially for curing diseases of the skin 89 both in men and in horses: and its springs are thirty-eight in number, flowing all from the same rock, of which some are cold and others warm. The way to them is of equal length from the city of Heraion near Perinthos and from Apollonia upon the Euxine Sea, that is to say two days' journey by each road. This Tearos runs into the river Contadesdos and the Contadesdos into the Agrianes and the Agrianes into the Hebros, which flows into the sea by the city of Ainos.
91. Dareios then, having come to this river and having encamped there, was pleased with the river and set up a pillar there also, with an inscription as follows: "The head-springs of the river Tearos give the best and fairest water of all rivers; and to them came leading an army against the Scythians the best and fairest of all men, Dareios the son of Hystaspes, of the Persians and of all the Continent king." These were the words which were there written.
92. Dareios then set out from thence and came to another river whose name is Artescos, which flows through the land of the Odrysians. Having come to this river he did as follows:—he appointed a place for his army and bade every man as he passed out by it place one stone in this appointed place: and when the army had performed this, then he marched away his army leaving behind great mounds of these stones.
93. But before he came to the Ister he conquered first the Getai, who believe in immortality: for the Thracians who occupy Salmydessos and are settled above the cities of Apollonian and Mesambria, called the Kyrmianai 90 and the Nipsaioi, delivered themselves over to Dareios without fighting; but the Getai, who are the bravest and the most upright in their dealings of all the Thracians, having betaken themselves to obstinacy were forthwith subdued.
94. And their belief in immortality is of this kind, that is to say, they hold that they do not die, but that he who is killed goes to Salmoxis, 91 a divinity, 92 whom some of them call Gebeleizis; and at intervals of four years 93 they send one of themselves, whomsoever the lot may select, as a messenger to Salmoxis, charging him with such requests as they have to make on each occasion; and they send him thus:—certain of them who are appointed for this have three javelins, and others meanwhile take hold on both sides of him who is being sent to Salmoxis, both by his hands and his feet, and first they swing him up, then throw him into the air so as to fall upon the spear-points: and if when he is pierced through he is killed, they think that the god is favourable to them; but if he is not killed, they find fault with the messenger himself, calling him a worthless man, and then having found fault with him they send another: and they give him the charge beforehand, while he is yet alive. These same Thracians also shoot arrows up towards the sky when thunder and lightning come, and use threats to the god, not believing that there exists any other god except their own.
