The Helmet is the ‘piece of the armor, that covers and defends the head’. In the early medieval centuries, to protect the head we used a simple helmet of metal, of conical shape, without a brim or jugular to which it was added in the tenth century appendix nasal rectum. Subsequently was added the visor, movable part and the most important of the helm or helmet, covering the face of the warrior during the fight, which arose when there was need of fresh air and a better look at the objects. In the Middle Ages consisted of three parts:
- the visor itself, which had holes or slots to provide free passage of air and easy viewing: this part was defending the eyes
- the nasal
- the ventalla
The visor is an invention very old as seen on the helmets of the greeks and of the etruscans, as well as those used in the tenth century and beyond.
