After the wars in Afghanistan and Iraq there has been a lot of talking about how many soldiers suffer from PTSD when they return home.
I'm interested in knowing more about war trauma and PTSD in ancient warfare. It would perhaps be useful to narrow it down to the lets say the Roman era.
I imagine that wars back then can be considered more "brutal" than what we have today, most of the fighting happening in very close combat with many dead and dismembered bodies laying around (as opposed to the relatively small engagements modern armies are use to today and of course the fighting parties tend to keep greater distances between themselves nowadays). My initial guess would be that soldiers surviving these engagements would suffer from terrible trauma.
On the other hand, these people would have led more "brutal" lives than we have today. I imagine they would have been exposed to violence at younger ages (crucifixion of criminals, arguments ending up with swords, animal and possibly human sacrifices, more instances of death around them etc...). Additionally I imagine their culture and religions probably prepared them for this level of violence. Compare that with the childhood and the life the average (Christian, religion that doesn't really prepare for war and violence) westerner lives before seeing war for the first time.
I'm particularly interested in knowing if any ancient writers left any records talking about war trauma in soldiers of their time?
