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 strikes. A mace typically consists of a strong, heavy, wooden or metal shaft, often reinforced with metal, featuring a head made of stone, bone, 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 sixty to ninety centimetres). 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 many government bodies (for instance, the British House of Commons and 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. Etymology The Middle English word "mace" comes from the French "masse" (short for "Masse d'armes") meaning ‘large hammer’, a hammer with a heavy mass at the end. Development history Prehistory The mace was developed during the Upper Paleolithic from the simple club, by adding sharp spikes of flint or obsidian. In Europe, an elaborately carved ceremonial flint mace head was one of the artifacts discovered in excavations of the Neolithic mound of Knowth in Ireland, and Bronze Age archaeology cites numerous finds of perforated mace heads. In ancient Ukraine, stone mace heads were first used nearly eight millennia ago. The others known were disc maces with oddly formed stones mounted perpendicularly to their handle. The Narmer Palette shows a king swinging a mace. See the articles on the Narmer Macehead and the Scorpion Macehead for examples of decorated maces inscribed with the names of kings. The problem with early maces was that their stone heads shattered easily and it was difficult to fix the head to the wooden handle reliably. The Egyptians attempted to give them a disk shape in the predynastic period (about 3850–3650 BC) in order to increase their impact and even provide some cutting capabilities, but this seems to have been a short-lived improvement. A rounded pear form of mace head known as a "piriform" replaced the disc mace in the Naqada II period of
