linothorax and other white cuirases

[Dan Howard]

Please show me any sculptures or painting of a quilted roman officers imperial armour, that Could match Suetonius lorica and I will agree on your claims.

You can't even tell whether something in a sculpture is made from metal, leather, or cloth. How are you supposed to tell whether something has been glued or quilted? Even on real examples you often can't see construction details. The examples above have an outer layer of leather or fine cloth that covers the quilting underneath. Stop looking at sculptures and go look at real armour.
