Hoplite Shield Designs

[Giannis K. Hoplite]

Stefane,I always remember to ask this in the inapropriate time,so here it is:
In your theory about shield emblems-lets take Sparta as only an example-you have categorised them in morae(one main separation at least).
So you speak of the emblem of the mora of Sparta,the gorgoneion,for example,or of Elos,the upside down horned bull etc.What picture do you have in mind,a whole mora,one sixth of the spartan army, having the same shield emblem,even in different fashions?Or even the majority of them having the same emblem.Or just in great frequency?I find that a bit strange.
Or for example,you connect some emblems with specific towns or islands,what do you think of them,that the majority of hoplites had this emblem on their shield,or your conclusion is that this emblem was just another one among the hundreds the existed in the town?
