What I'm seeing in the Mosaic are Intercisa type helmets with an Attic type helmet browguard attached. Unlike monumental carvings or painted artworks its very difficult to represent what your trying to depict using tiny bits of coloured stone, which basically what Mosaic's are. This would account for the rather odd look given to the helmets.
