The St Louis Art Museum Helm

[hoplite14gr]

Most of the elaborate animals on medieval knights helmets were made of "soft material" so as not to add weight. Most of this helmets were like "riveted" on the torso armor too. I do not doubt that extravagant helmets would have existed in the ancient times but this one is unpractical for battle. As Paul suggested it is unbalanced. I have serios doubt if someone can perform the 100 meter sprint charging in full armor with this monstrocity on his head. Only an exterm fool or someone with a deathwish would encumber himself like that.
Kind regards
