About this subject

The visor of a knight's helmet is an iconic piece of medieval armor, designed to protect the face without completely obstructing vision. During the 14th and 15th centuries, visors evolved from simple fixed plates to articulated mechanisms, such as those found on armet and barbute helmets. The horizontal (or cross-shaped) slits allowed the knight to see the battlefield, while small breathing holes ensured minimal ventilation. The metal thickness ranged from 2 to 4 mm, capable of deflecting sword blows and arrows.

Visor design also reflected the fashion and heraldry of the era. Many helmets were adorned with crests, plumes, and family insignia, but the visor itself remained functional. The artisanal production of these pieces required specialized blacksmiths who used techniques of tempering and hot hammering. More elaborate visors, such as those on jousting helmets, had narrower slits for added protection but sacrificed field of view.

Interestingly, the visor has influenced modern visual language: its shape is often associated with knights, security, and secrecy, appearing in logos and fantasy films. In the 19th century, the Gothic Revival brought replicas of these helmets for decoration and ceremonies, solidifying the visor as a symbol of courage and nobility. Today, museums like the Metropolitan Museum of Art and Brazil's Army Museum preserve original pieces that allow for the study of medieval metallurgy.
