Mace-bearer
A mace-bearer, or macebearer, is a person who carries a mace, either a real weapon or ceremonial.
Armed[edit]
When the mace was still in actual use as a weapon, it was deemed fit for close-protection, and hence a mace-bearer could be a bodyguard.
Thus in French and Dutch, a massier (armed with a masse d'armes 'weapon-mace') could be a member of a formally so-styled guard corps, as in the court of the Dukes of Brabant.
In Spain, a macero were originally an armed guard protecting the King of Castile; they were called macero due to the weapon they wielded, a maza (i.e., a mace).
Otherwise, a normally more domestic servant could double (arming trusted household staff was not unusual) as macebearer, as in the case of the prophet Mohammed's first muezzin, Bilal ibn Ribah
