Mace (club)
A mace is a blunt weapon, a type of club or virge—that uses a heavy head on the end of a handle to deliver powerful blows. A mace typically consists of a strong, heavy, wooden or metal shaft, often reinforced with metal, featuring a head made of stone, copper, bronze, iron, or steel.
The head of a military mace can be shaped with flanges or knobs to allow greater penetration of plate armour. The length of maces can vary considerably. The maces of foot soldiers were usually quite short (two or three feet, or 70 to 90 cm). The maces of cavalrymen were longer and thus better suited for blows delivered from horseback. Two-handed maces could be even larger.
Maces are rarely used today for actual combat, but a large number of government bodies (for instance the British House of Commons, the U.S. Congress), universities and other institutions have ceremonial maces and continue to display them as symbols of authority. They are often paraded in academic, parliamentary or civic rituals and processions.
