Galatian mercenaries, hired from the Celtic tribes on the central plateau of Asia Minor, were not uncommon in Successor armies. These depict mercenaries serving the Ptolemies, and are loosely based on the reconstruction in the Ptolemaic Montvert; I'm very pleased with them. The images are clickeable, and previous posts show the various stages of painting.
Is it my imagination, or is the woman in the background, below, smiling as they approach her? ;-)
