Figure 5 Two common categories of benefactions depend upon each other and com- nent upon the geopolitical situation in Pontic Greek cities. Embassies and mili- ary efforts often went hand in hand in the pre-Roman period, with these two ypes of munificence amounting to ca. 32% of all registered examples. As men- ioned previously, the hold of the Greek Black Sea colonies on the neighbour- ng lands was often tenouous. The examples of Protagenes and Nikeratos from IIbia, the defenders of Mesambria, Akornion from Dionysopolis or Diogenes ind Agathokles from Istros reveal that neighbouring barbarian rulers attacked -ontic Greek poleis, negotiated with Greek envoys about the ransom of hostages ind, finally, demanded tribute from defeated city-states**. This kind of public nunificence grew in significance in Hellenistic times, as a successful diplomatic nission could save a city from destruction, an example in point being the case yf Dionysopolis during Burebista’s invasion.
