History of the Peloponnesian War

The extent then of the Odrysian dominion, taking the line of its sea-coast, was from the city of Abdera to the Euxine, up to the mouth of the Danube. This tract is by the shortest way a voyage of four days and nights for a merchant-vessel, supposing the wind to be always steady astern. By land, taking the shortest way from Abdera to the [mouth of] the Danube, a quick traveller performs the journey in eleven days.

Such was the extent of its sea-board. As for the in terror, from Byzantium to the Laeaeans and the Strymon, (for at this point it reached its greatest extent up the country from the sea,) for a quick traveller it was a journey of thirteen days.

The tribute raised from all the barbarian dominions and the Grecian cities, taking the sum which they paid under Seuthes, who was successor of Sitalces, and raised it to its greatest amount, was about 400 talents in gold and silver. Presents were also made to no less an amount in gold and silver; and besides these there was all the clothing, both figured and plain, and other articles for use; and that not only for himself, but for those of the Odrysians also who were his lords and nobles.

For they established their custom the very reverse of that in the Persian kingdom, (though it prevails amongst the rest of the Thracians also,) namely, to receive rather than to give; and it was considered more disgraceful not to give when asked, than not to succeed by asking. But [though the other Thracians practised the same thing], still the Odrysians, owing to their greater power, practised it to a greater extent; for it was impossible to get any thing done without making presents.

The kingdom then had reached a high pitch of power. For of all those in Europe between the Ionian Gulf and the Euxine Sea, it was the greatest in amount of revenue and general prosperity; while in military power and number of troops it was decidedly next to that of the Scythians.

But with this not only is it impossible for those in Europe to vie, but even in Asia, putting one nation against another, there is none that can stand up against the Thracians, if they are all unanimous. Not, however, that they are on a level with other men in general good management and understanding in the things of common life.
