Here are the Thracian tribes through whose territory he travelled: the Paeti, Cicones, Bistones, Sapaei, Dersaei, Edonians, and Satrae. Some of them lived on the coast, and they went along with their ships, while the inland tribes from this list of mine were all forcibly conscripted into the land army--all except the Satrae, that is.
The Satrae have never been subject to anyone, as far as we know; they are the only tribe in Thrace to have retained independence all the way up to my day. They live in a region of high mountains which are thickly wooded with all kinds of trees and covered with snow; they are also extremely good fighters. They are the ones who have the oracle of Dionysus in the highest part of the mountain range in their country. The pronouncements at this shrine are interpreted by the Bessians, a sub-tribe within the Satrae, and as at Delphi it is a prophetess who is the mouthpiece, and her utterances are no more elaborate than those of her counterpart at Delphi.
