A \'new\' look at the linothorax

[hoplite14gr]

In what period the statuettes are dated?
Is it beyond reasonable doubt that their armor is non metallic?

As for Greeks the first appearence of "linothoriktos" is by 800 B.C. (Homer Iliad)
Based on that we can say Late Geometric Era but assuming he talks about Late Bronze Age items he has clearly seen (boar tusk helemt for example) We can speculate that this armor existed in Greece from 1200 B.C. The issue will be more clear when the "Thebes Arsenal" findings are going to be published.

Assuming there is a non Greek artifact depicting non metallic armor and dated before lets say 1000 B.C. what arguments are there for this not being a Greek invention?
