Italy, Milan / c. 1475–1500
War Hat (or Kettle Hat)
The Cleveland Museum of Art catalogs War Hat (or Kettle Hat) as arms and armor (Italy, Milan · c. 1475–1500).
The rivets along the rim were not only decorative, but a means of attachment for a liner.
A CLOSER LOOK
The museum identifies this arms and armor as steel and credits Antonio Missaglia (Italian, 1416/17–1495/96).
The museum's collection notes: Open helmets like this one were in use from the 1200s to the 1400s and are the ancestor of today's common military helmet. Such helmets were worn by foot soldiers as they attempted to scale the walls of an armed town. The slight ridge, or comb, down the center served to improve deflection and increase strength. Antonio Missaglia's workshop created helmets like this for royalty and knights in the region of Milan. Missaglia inherited the workshop from his father, who was also an armorer, and employed craftsmen who specialized in particular types of armor, such as jointed arm defenses or helmets.
