proconsuls had not been enough to curb the pretensions of the Greek notables. It is noteworthy that an embassy from Dio's city of Prusa was not favourably received by Trajan, and that this had to do with Dio's chief objective, which was to elevate Prusa to the status of a free city, an "independent" city-state exempt from paying taxes to Rome. Eventually, Dio gained for Prusa the right to become the head of the assize-district, conventus (meaning that Prusans did not have to travel to be judged by the Roman governor), but eleutheria (freedom, in the sense of full political autonomy) was denied. Eventually, it fell to Pliny, as imperial governor of Bithynia in 110AD, to deal with the consequences of the financial mess wrought by Dio and his fellow civic officials. "It's well established that [the cities' finances] are in a state of disorder", Pliny once wrote to Trajan, plans for unnecessary works made in collusion with local contractors being identified as one of the main problems. One of the compensatory measures proposed by Pliny expressed a thoroughly Roman conservative position: as the cities' financial solvency depended on the councilmen's purses, it was necessary to have more councilmen on the local city councils. According to Pliny, the best way to achieve this was to lower the minimum age for holding a seat on the council, making it possible for more sons of the established oligarchical families to join and thus contribute to civic spending; this was seen as preferable to enrolling non-noble wealthy upstarts. Such an increase in the number of council members was granted to Dio's city of Prusa, to the dismay of existing councilmen who felt their status lowered. A similar situation existed in Claudiopolis, where a public bath was built with the proceeds from the entrance fees paid by "supernumerary" members of the council, enrolled with Trajan's permission. According to the Digest, Trajan decreed that when a city magistrate promised to achieve a particular public building, his heirs inherited responsibility for its completion. Building projects Trajan was a prolific builder. Many of his buildings were designed and erected by the gifted architect Apollodorus of Damascus, including a massive bridge over the Danube, which the Roman army and its reinforcements could use regardless of weather; the Danube sometimes froze over in winter, but seldom enough to bear the passage of a party of soldiers.
