Linothorax vs Quilted linen vs spolas

[Dan Howard]

Type and yoke quilted and segmented.
This example coming from ancient pottery was reinforced with metal.

What? How can you tell from pottery whether something is made of metal or not and how do you know rivets are being represented? A good example is the Terracotta warriors. The plates are depicted with small dots and people have been interpreting them as rivets for years. We know know that they are small patches of lacing. On top of that people thought that the plates were made of metal but 12 examples were later found at Leigudun. When assembled they look exactly like the terracotta examples. IIRC all 12 of them are made of lacquered leather, not metal.

On top of that, if the illustration is supposed to be representing segmented plate they would not be aligned vertically, it removes any flexibility at the waist. They would be horizontally aligned.
