Shields?

[Ibrahim]

the anecdote is in Plutarch's sayings btw. And yeah, i could see shield recognition being used during/after the civil wars as a way to identify romans from other romans.

I see. I will try to check it out.

well, all I know about roman shields is tied to the late empire: namely the Notitia dignitatum. they have some really fancy patterns for the various field army regiments, so I know that at least in the late empire the shields followed regimental lines with each shield referring to a different unit.
