Bear with me on this one there is a bit of lateral thinking going on. Or rambling.Which given the foul cold I am currently enduring may be more likely. I apologize if some of this is all greek to you, but my powers of explanation have also deserted me.
Normally one would picture a thorakites as a slightly better armoured thureophoros with a light mail shirt in addition to his thureos shield; but I got to thinking earlier, would the cuirass worn necessarily be of mail? Would it not be equally likely that this was of the more traditional linothorax type & if so what would this combination look like:
Actually not bad, almost like a latter day hypaspist ( depending on your point of view) & quite suitable for standing in line of battle as flank protection for the phalanx as well as providing a solid anchor for the thureophoroi while operating in rough country.
