Fastening Greek helmets

[Giannis K. Hoplite]

I have never read of that theory,but it correspons with the experience of Christian and his new custom made bronze helmet. He says he has to press the sides while wearing it! This might have been true with some helmets, but many,if not most of them have holes for fastening. And given that helmets passed from father to son,this couldn't have been a universal characteristic. My helmets don't fit my father's head! Nor that of two friends of mine! It doesn't have to do with the circumference but by the width of the head.
