These Masonic aprons are part of a larger set of officer aprons. They would have belonged to a lodge, which passed them out at meetings to the men who were serving in the various offices at the time. As the officers rotated in and out of their respective positions, the aprons were passed along to the next person to fill that role.

A full set of officer aprons would number fourteen. Each one shows the symbol associated with the office: the square for the Master, the level for the Senior Warden, the plumb for the Junior Warden, the crossed quills for the Secretary, the crossed keys for the Treasurer, the square and compasses with sun for the Senior Deacon, the square and compasses with moon for the Junior Deacon, a cornucopia for the two Stewards, crossed swords for the Inner Guard, a single sword for the Tyler, a Bible for the chaplain, a lyre for the Organist, and a baton for the Marshal.
