[3: After the campaign of Crassus the conquered land was probably organised in such a way that the coast went to the Thracian kingdom, as Zippel has shown (_Röm. Illyricum_, p. 243), and the western portion was, just like Thrace, assigned in fief to the native princes, in place of one of whom must have come the _praefectus civitatium Moesiae et Triballiae_ (_C. I. L._ v. 1838), who was still acting under Tiberius. The usual assumption that Moesia was at first combined with Illyricum, rests only on the circumstance that in the enumeration of the provinces apportioned in the year 727 between emperor and senate in Dio, liii. 12 it is not named, and so was contained in "Dalmatia." But this enumeration does not extend at all to the vassal-states and the procuratorial provinces, and so far all is in due keeping with our assumption. On the other hand, weighty arguments tell against the usual hypothesis. Had Moesia been originally a part of the province of Illyricum, it would have retained this name; for on the division of a province the name was usually retained, and only a defining epithet added. But the appellation Illyricum, which Dio doubtless reproduces _l.c._, was always in this connection restricted to the upper (Dalmatia) and the lower (Pannonia). Moreover, if Moesia was a part of Illyricum, there was no room left for that Prefect of Moesia and Triballia, or in other words for his kingly predecessor. Lastly, it is far from probable that in 727 {27.} a command of such extent and importance should have been entrusted to a single senatorial governor. On the other hand, everything admits of easy explanation, if small client-states arose in Moesia after the war of Crassus; these were as such from the outset under the emperor, and, as the senate did not take part in their successive annexation and conversion into a governorship, this might easily be unnoticed in the Annals. It was completed in or before the year 743 {11.}, seeing that the governor, L. Calpurnius Piso then waging war against the Thracians, to whom Dio (liv. 34) erroneously assigns the province of Pamphylia, can only have had as his province Pannonia or Moesia, and, as at that time Tiberius was acting as legate in Pannonia, there is left for him only Moesia. In 6 A.D. there certainly appears an imperial governor of Moesia.] [4: The official title of Cottius was not king, like that of his father Donnus, but "president of the cantonal union" (_praefectus civitatium_), as he is named on the still standing arch of Susa erected by him in honour of Augustus in the year 745-6 {9-8.}. But the position was beyond doubt held for life, and, under reservation of the superior's right to confirm it, also hereditary; so far therefore the union was certainly a principality, as it is usually so termed.]
