A rare form of
visor , a defense for the face, most commonly used on tournament
helmets of the 15th century. The only surviving grilles are fitted onto
great bascinets ; such are amply described in King Rene d'Anjou's book on the tournament. There is a single example of a center mount
bascinet from the middle 14th century on a Bohemian altarpiece, c. 1360, the bears a grille as defense. The grille has become a standard defense in the
SCA , where modern re-enactors prefer the vision and breathing capability, not having to worry about sheared lances or the points of
swords
