A Greek Dark Age Centaur Armour

[Dan Howard]

It is so crude that you could interpret it any way you want. There is nothing to suggest a martial context such as a shield, weapon or helmet, so it is pure speculation whether it is wearing armour at all. Assuming it is armour, my first guess would be scale.

(Protogeometric crosshatching rarely, if ever, renders metal - it is usually used to suggest fibre, textile, leather etc.)

Nobody has any idea what crosshatching is supposed to represent. Everyone is just guessing. And most of those have no idea about armour. Cross hatching was a common method of representing metallic scale and mail in other cultures.

The arm decoration is the most curious part IMO. What is the earliest example of segmented plate arm armour?
