Book 4
92.1
From there, Darius set out and came to another river called Artescus, which flows through the country of the Odrysae; and having reached this river, he pointed out a spot to the army, and told every man to lay one stone as he passed in this spot that he pointed out. After his army did this, he led it away, leaving behind there great piles of stones.
93.1
But before he came to the Ister, he first took the Getae, who pretend to be immortal. The Thracians of Salmydessus and of the country above the towns of +Apollonia [14.5833,38.0167] (Perseus) Apollonia and Mesambria, who are called Cyrmianae and Nipsaei, surrendered without a fight to Darius; but the Getae resisted stubbornly, and were enslaved at once, the bravest and most just Thracians of all.
94.1
Their belief in their immortality is as follows: they believe that they do not die, but that one who perishes goes to the deity Salmoxis, or Gebeleïzis, as some of them call him.
94.2
Once every five years they choose one of their people by lot and send him as a messenger to Salmoxis, with instructions to report their needs; and this is how they send him: three lances are held by designated men; others seize the messenger to Salmoxis by his hands and feet, and swing and toss him up on to the spear-points.
