Leather Cuirass Lorica Musculata, I used to think no way but

[Tarbicus]

Then the possibility is there that they are depicting leather rather than metal cuirass's. After all, absence of evidence is not evidence of absence. :wink:
There are so many portrayals of soft cuirasses that is would not be to great a leap of faith to suppose that leather 'could' have been used.

But anyway, your cuirass is looking good there matey!!

Without proper tests being done on a leather cuirass using a heavy sword thrust with a sharp tip and edge, the leather cuirass would have to be so thick there's no way it would bend when left to rest on the ground. I'm really impressed with the way the leather stood up to a kitchen knife, but a sword with the extra mass might be a different thing altogether.
