This part contains Greece, Macedonia, Epirus, and the people who live above them, extending to the Danube and to the two seas (the Adriatic and the Euxine Sea) on each side. On the Adriatic are the Illyrians; on the Euxine Sea, as far as the Propontis[2751] and Hellespont, are the Thracians, and the Scythian or Keltic tribes intermixed with them. We must begin from the Danube, and treat of the countries which follow next in order to those already described, that is to say, the parts contiguous to Italy, the Alps, the Germans, the Dacians, and the Getæ.
These may be divided into two parts. For the mountains of Illyria, Pæonia, and Thrace, may be considered as forming, as it were, a single line, parallel to the Danube, and extending from the Adriatic to the Euxine. To the north of this line is the country included between the Danube and the mountains. To the south is Greece and the barbarous tract contiguous to these mountains.
Near the Euxine Sea is Mount Hæmus,[2752] the largest and the highest of the mountains in that quarter, and divides Thrace nearly in the middle. According to Polybius, both seas may be seen from this mountain; but he is mistaken, for the distance to the Adriatic is considerable, and many things obstruct the view.
Almost the whole of Ardia[2753] lies near the Adriatic, Pæonia is in the middle, and all this country consists of elevated ground. On the side towards Thrace, it is bounded by Rhodope,[2754] a mountain next in height to Hæmus; on the other side to the north is Illyria, and the country of the Autariatæ,[2755] and Dardania.[2756]
I shall first describe Illyria, which approaches close to the Danube, and to the Alps which lie between Italy and Germany, [CAS. 314] taking their commencement from the lake in the territory of the Vindelici, Rhæti, and Helvetii.[2757]
The rest of the country as far as Segestica,[2759] and the Danube, towards the north and east, is occupied by Pannonii, but they extend farther in an opposite direction. The city Segestica, belonging to the Pannonii, is situated at the confluence of several rivers, all of which are navigable. It is in a convenient situation for carrying on war against the Daci, for it lies at the foot of the Alps, which extend to the Iapodes,[2760] a mixed Keltic and Illyrian tribe. Thence also flow the rivers by which is conveyed to Segestica a great quantity of merchandise, and among the rest, commodities from Italy. The distance from Aquileia to Nauportus,[2761] a settlement of the Taurisci, across the mountain Ocra,[2762] is 350, or, according to some writers, 500 stadia. Merchandise is transported to Nauportus in waggons. The Ocra is the lowest part of the Alps, which extend from Rhætica to the Iapodes, where the mountains rise again, and are called Albii. From Tergeste,[2763] a village of the Carni,[2764] there is a pass across and through the Ocra to a marsh called Lugeum.[2765] A river, the Corcoras, flows near Nauportus, and conveys the merchandise from that place. It discharges itself into the Save, and this latter river into the Drave; the Drave again into the Noarus at Segestica. Here the Noarus, having received the Colapis[2766] as it descends in its full stream from the mountain Albius through the Iapodes, enters the Danube among the Scordisci. The navigation on the rivers is in general towards the north. The journey from Tergeste to the Danube is about 1200 stadia. Near Segestica is Siscia, a strong-hold, and Sirmium, both situated on the road to Italy.
