A roundhead was a type of mace used during the English Civil War. It is described as having a head about 9 inches (23 cm), a staff 2 yards (1.8 m) long inserted into the head, twelve iron spikes round about, with another spike in the end.[1][2] In 1643 an article in Mercurius Civicus claimed the weapon was called a roundhead by the Cavaliers because they were to be used to beat the Roundheads into subjection.[3]
