    • n helmet A defensive cover for the head. The term is applied in general to all defensive head-coverings except the slightest, such as the skull-cap, the secret, the wire hat, etc., and also the camail or coif. Specifically — Milit.: In ancient and medieval armor, a cap of metal worn to protect the head from sword-cuts and spear-thrusts. Such a helmet usually guarded the nape of the neck and sides of the face by means of hinged pieces or sliding splints (see coucre-nuque, face-guard, cheekpiece); and to a certain extent the face by means of a nasal, either fixed or movable, a beaver, a projecting vizor, or the like. The only helmets which covered the head and face completely were those worn by Roman gladiators of certain classes, and by medieval heavy-armed horsemen between the beginning of the thirteenth and the-middle of the sixteenth century; the most completely defensive helmets were the tilting-helmets of the fifteenth and sixteenth centuries, which prevented the wearer from seeing except directly before him, and at a height on a line with his eyes. See armet, barrel helm (under helm), basinet, beaver, burganet, cabasset, heaume, iron-cap, lumière, mentonnière, morion, nasal, œillère, ombril, tilting-helmet, vizor.
