A cuirass is a piece of armor that protects the torso, covering the chest and back. It was commonly used in ancient and medieval warfare, made from materials like metal or leather. The design of a cuirass allows for mobility while providing essential protection against weapons. Cuirasses were often worn by soldiers and knights, such as those in the European Middle Ages. They could be simple or elaborately decorated, reflecting the status of the wearer. The term can also refer to modern body armor, which serves a similar purpose in protecting vital organs during combat or dangerous situations.
