These are the native-born Scythian rivers that help to swell it; but the Maris river, which commingles with the Ister, flows from the Agathyrsi. The Atlas, Auras, and Tibisis, three other great rivers that pour into it, flow north from the heights of Haemus. The Athrys, the Noes, and the Artanes flow into the Ister from the country of the Crobyzi in Thrace; the Cius river, which cuts through the middle of Haemus, from the Paeonians and the mountain range of Rhodope. The Angrus river flows north from Illyria into the Triballic plain and the Brongus river, and the Brongus into the Ister, which receives these two great rivers into itself. The Carpis and another river called Alpis also flow northward, from the country north of the Ombrici, to flow into it; for the Ister traverses the whole of Europe, rising among the Celts, who are the most westerly dwellers in Europe, except for the Cynetes, and flowing thus clean across Europe it issues forth along the borders of Scythia.
