the natural base was not Buda, but Vienna. [Sidenote: Thracian war of Piso.] Complementary in some measure to this Pannonian expedition of Tiberius was that which was simultaneously undertaken against the Thracians by Lucius Piso, perhaps the first governor that Moesia had of its own. The two great neighbouring nations, the Illyrians and the Thracians, of whom we shall treat more fully in a subsequent chapter, stood alike at that time in need of subjugation. The tribes of inland Thrace showed themselves still more obstinate than the Illyrians, and far from subordinate to the kings set over them by Rome; in 738 {16.} a Roman army had to advance thither and come to the help of the princes against the Bessi. If we had more exact accounts of the conflicts waged in the one quarter as in the other in the years 741 to 743 {13 to 11.}, the contemporary action of the Thracians and Illyrians would perhaps appear as concerted. Certain it is that the mass of the Thracian tribes south of the Haemus and presumably also those settled in Moesia took part in this national war, and that the resistance of the Thracians was not less obstinate than that of the Illyrians. It was for them at the same time a religious war; the shrine of Dionysos,[6] taken from the Bessi and assigned to the Odrysian princes well disposed to Rome, was not forgotten; a priest of this Dionysos stood at the head of the insurrection, and it was directed in the first instance against those Odrysian princes. One of them was taken and put to death, the other was driven away; the insurgents, in part armed and disciplined after the Roman model, were victors in the first engagement over Piso, and penetrated as far as Macedonia and into the Thracian Chersonese; fears were entertained for Asia. Ultimately, however, Roman discipline gained the superiority over these brave opponents; in several campaigns Piso mastered the resistance, and the command of Moesia, instituted either already on this occasion or soon afterwards on "the Thracian shore," broke up the connection of the Daco-Thracian peoples, by separating the tribes on the left bank of the Danube and their kinsmen south of the Haemus from each other, and permanently secured the Roman rule in the region of the lower Danube.
