Darius\' Mercenaries

[hoplite14gr]

If they were hired as a group from an area they would be probably having the same shield device.

I asume you probably talk about Dareios Kodomanos who fought Alexander.
By that time the city monogram had substituted the older devices with the probable exception of Thebes.

Troops could have been raised either from mainland Greece or the Ionic or even Pontic colonies.

We have no evidence (at least for the time being) that Dareios presented colors or symbols to a unit or continent.

I do not agree with Jona completely because at a late Era the raven was an ill omen to ""Romeoi" but the Varangians used it none the less.

Greek spearmen were elit in the Persian army but not bodyguard unit so they could maintain their own shield devices.

Kind regards
