Linothorax vs Spolas

[Giannis K. Hoplite]

We know that both helmet padding and arming caps co existed in Ancient Greece.
So any rational objection why "padding attachment" and subarmalis did not coexist?

Yes,because we have numerous representatons of the former and none of the latter.
Also, never do we hear of an arming cap worn as armour in its own right.
We will have to agree to disagree about all the images you posted in your last post, because i don't see the chance of subarmalis shown in any single one of them.
As for the chance of Xenophon meaning "thorakes with their spolades", this can readily be rejected by Pollux who specifically tells us that Xenophon says "spolas instead of thorax".
And we still have no mention of subarmalis, whereas we do have for arming caps (Aristotle)
Finally, we can only make any worthy conclusions if we do tests with EXACT replicas of ancient body armour, meaning that they will fit the wearer as well, and they will have the same thickness and weight. And we cannot sucrifice any of the above, if we want our experiment to have any value.
