Another interesting angle on this question comes from the Jaynes bicameral mind hypothesis [0]. Given that a major component of PTSD is moral injury -- e.g., I can't believe someone intentionally did that to me / I can't believe I had to do that to someone else -- I wonder whether (if the bicameral mind theory is true which I think it is) ancient warriors experienced PTSD not as internal angst but rather as a "dialogue among the gods" that happened in one's head following stress.
