They started life as Crusader miniatures Persian Kardakes, I then took a scalpel to their tiara headdresses and replaced them with the shaggy hair and beards now sported. The spear and javelin armament is again speculative but at least probable though I may mix in a few more figures with multiple javelins for variety. The thureos shield would again be a possibility, it was fairly ubiquitous throughout the hellenistic world, but equally a small round buckler type could be mixed in to give a more irregular appearance. The OTT lion head shield is one of three included in a pack of Palmyran cataphracts bought from A&A miniatures and included simply because I like it.
So there you have it a fairly generic pair of irregulars to trail along in the wake of the cavalry and doing all the menial tasks and helping the nobles feel superior.
