Late Roman helmets, Byzantine

[AMELIANVS]

I've never seen that image before! (Tours/Ashburnham )
Interesting helmet and crest images.
I wonder if the use of iron/silver vs bronze is to depict different sides in a civil war scenario?

There is always the possibility that there are some aspects borrowed from contemporary reality but in this case biblical crossing of the red sea is depicted and Roman soldiers represents those of Egypt.
