The depiction of Artemis-Diana on the reverse of the tetradrachm corresponds to the canonical representation of the huntress deity that we find on several mint coins of the classical and Hellenistic worlds, very different from that of the Ephesian Artemis. A review of these images can be found on Imhoof-Blumer, F.- Gardiner, P., A Numismata Commentary on Pausanias, reprint from the Journal of Hellenistic Studies 1885-1887, London, 1887.
