Info. on Legio II Parthica

[Robert Vermaat]

The largest difference between these shields, I'd say, is that the II Parthica shield is yellow with a dark rim, and the Scholae shield is dark with a yellow rim.

Ah, but the red and yellow shield in the illustration is 'dark' with a 'light' rim! - since the mosaic was in black and white, the 'dark' red could just as easily have been blue or black...

Indeed it could've been, but on that shield, the centre portion is very different...
Same thing - the designs look alike, but aren't exactly simlar.
Mind you, I'm not saying that you're wrong! I just wanted to draw attention to the fact that apparently, very differing units could have shield designs that look extremely similar, but bear no relation to each other.
