Just thought my readers would like to see the incredible range of materials and designs which have been turned into body armour over the years.
So who would wear such an armour? An actual Roman legionaire? Unlikely a regular soldier. Possibly a special troupie...like say, a Chief Warrant Officer (Centurion). They generally wore a lion skin cloak with the head of the lion mounted on the helmet and the feet wrapped around the shoulders and tied in front. We know this from bas reliefs of the time. I would not for an instant put it past a creative commander to think to himself...."these crocs are pretty cool! Wonder if a croc skin could replace that musty moth eaten lion skin I was issued."
Personally I could see that happening with an auxiliary troup...say a small regiment of Egyptians who wanted to retain their distinctivness. Later in the forth and fifth centuries, such troups were allowed to retain portions of their distinct regional iconic dress...the Persian troops were allowed to retain their phyringian caps for instance.
Well, this is only speculation. Isn't it amazing how the mind runs wild with speculation when all you have is a suit in a glass case?
