Above is the army arrayed in full. Like the Spartans they have a nice uniform appearance, but this time a white theme. They were a good match for the Spartans, not just in terms of appearance but in fighting ability too.
Above are the hoplites and general elements.
Then the Cavalry Auxilliary and psiloi elements.
If you would like a Theban army painting drop me an email firstname.lastname@example.org
I may go in an Easterly direction next...to Persia.
