Linothorax vs Spolas

[Giannis K. Hoplite]

Then i would challenge three answers:
Where does an undergarment appear in greek art, in the many ocasions that we see worn and unworn muscle cuirasses?
Why was a Spartan wearing only an undergarment in battle, and why its penetration was something worth mentioning to suggest the strenght of the missile?
Why doesn't Xenophon ever mention it when he extensively speaks of the good fitting of metal armour, and even suggests the use of cuirasses with long pteryges to cover the thighs? He doesn't speak of a "spolas" with long pteryges, nor that a spolas makes the cuirass fit better.

None of these are conclusive or near to it of course, but i would say that they certainly point to a spolas meaning a kind of cuirass rather than armour padding.
