How to portray a Spartan king from the classical era?

[Giannis K. Hoplite]

I'm wondering was this standard or were there exceptions?(the skiritians? Tegeans?)

Tegeans had their own shield emblem

The Tegeans were not Perioikoi,they were allies of Sparta and the distinction was also clear.The Peloponnesian leage was not Sparta's subordinate but full right allies,like Thebes and Corinth. However Tegeas was a close neighbour of Sparta,highly influenced by her and rather vital. Certainly not a perioic town.
