pretorian and subarmalis

[Theodosius the Great]

The two Praetorians that Aurelianus highlights may not be cavalrymen afterall. If their shields were flat then they must be cavalrymen (or auxiliaries). But if you look at the guy on the left, his shield looks as if it's cylindrically curved like a legionary scutum. See how his left shoulder leans into a groove ? So, now I'm inclined to think they can't be cavalrymen.

Any thoughts ?
