A ceremonial long mace is a long mace, a polearm variant of a mace, designed for ceremonial purposes rather than for warfare. Despite this, the ceremonial long maces of the Parisian Brotherhood of Assassins were among the most powerful pole weapons of the French Revolution.
A long mace is essentially a mace head mounted atop a long shaft. In essence, what a saber is to a glaive, a mace is to a long mace. A ceremonial long mace, as its name implies however, is a long mace created not with the intention of combat in mind, but to serve as a symbol of status in ceremonial settings.
Ironically, the ceremonial long mace of the Parisian Brotherhood was one of the most effective weapons in their arsenal at the time of the French Revolution. That its role as a weapon came second for its blacksmiths ultimately did not dampen its quality as a combat weapon. In spite of its ostensibly non-combat function, the golden mace-head was covered entirely in sharp spikes.
During the French Revolution, the ceremonial long mace was one of the myriad of weapons the Parisian Brotherhood of Assassins had access to. The weapon, among the deadliest of polearms in Paris at the time, was sold in the city for 25,000 francs.
