Metal plate beneath Linothorakes or Spolades

[Dan Howard]

I have seen 2mm thick bronze penetrated by multiple arrows (with different arrowheads)

Not using enough tin in the alloy decreases the protectiveness of the armour.
Not work hardening it properly decreases the protectiveness of the armour.
Using a flat sheet rather than a shaped breastplate decreases the protectiveness of the armour.
Not attaching a liner to the bronze decreases the protectiveness of the armour.
Not wearing a tunic under the bronze decreases the protectiveness of the armour.

Unless all of the above were simulated then the test tells us little about the performance of Greek armour.
