For most of the century nasal helmets with a forward deflected apex, often called the "Phrygian cap" shape, were in widespread use.
King Richard I of England is depicted wearing a round-skulled nasal helmet on his first Great Seal (1189).
[8] The existing nasal formed the basis for increased facial protection, eventually, by 1200, producing a face covering plate which was pierced for sight and ventilation.
Round-skulled nasal helmets can also be seen worn by a proportion of knights throughout the French Maciejowski Bible dating to 1250.
The nasal helmet would usually have been worn over a mail coif, which protected the lower parts of the head, throat and neck.
