TYPE Ancient Greece, Istros (Thrace), 4th c. BC, bronze AE15 DESCRIPTION . Obv: Horned and bearded head of river-god Istros (Danube), facing 3/4 right Rev: Eagle on top of dolphin, Greek legend "ISTR[ION]" REFERENCE: L3 A41f, BMC 15 GRADING: VF / F, dark brown patina, reverse porous, very scarce ORDER INFO: G2921, $100 Interesting early depiction of elusive river-god Istros (Danube). For all the might of the greatest European river (save the Volga), it remained at the edge of the ancient Greek world, and as such its divine personificatoin only occasionally appears on coinage. When so, it is typically as a reclining figure holding a reed on later colonial issues, but rarely in the present form, dating back to the Classical period.
