Sassanian body armour - cuirass

[Renatus]

IMO Firuzaband is depicting quilted cloth leggings, not banded metallic armour. This style of clothing was apparently worn at the time.

We have been down this road earlier in this thread. For what it is worth, I go for metallic armour. In my view, the Roman clibanarius was based on the Sassanian model and all the descriptions of him, actual and poetic, imply that his armour was of metal. Similarly, when Ammianus describes the Sassanian heavily-armoured warrior, he mentions only metallic armour.
