Feathers on Hellenistic Helmets

[Giannis K. Hoplite]

Crests as protection...yes they must have protected you some if you received a blow directly on it,but this is not a purpose of the crest. Most helmets appear not to have had crests at all.
Feathers can't have had a protective function at all. They're far too delicate and fashion is a very good reason for their presence. They're also cheaper than horsehair.
Don't underestimate fashion and beauty in ancient warriors. They most often did odd and really uncomfortable things for the shake of appearence. I found that the crest on my helmet is a real pain in the neck,my helmet is much lighter without it. And less impressive,too.
