This article is about the 18th century mace. You may be looking for the Morning Star, a 5th century BCE mace.
A morningstar, or l'étoile du matin in French, is a mace whose head is adorned entirely with spikes.
A modification of the mace, the basic profile of a morningstar therefore consists of a spherical metal head mounted atop a shaft. It distinguishes itself for the spikes that cover this ball, greatly enhancing its lethality. Alongside the usual crushing power of a mace, these spikes ensure that a morningstar can utterly pulverize a human's skull with one smash. It was similar, in some respects, to earlier flanged maces.
