Where does the word 'tyler' come from?
The term Tyler in Freemasonry originates from the historical role of a gatekeeper or guard, responsible for securing the entrance to a meeting place. This practice dates back to the medieval stonemasons' guilds, from which Freemasonry evolved. The Tyler's duty was to ensure that only qualified individuals were admitted to the lodge. As Albert G. Mackey states in his Encyclopedia of Freemasonry, the Tyler "is an officer of the lodge, whose duty it is to guard the door of the lodge room, and to see that none enter without the proper qualifications." This role emphasizes the importance of order, security, and the preservation of the fraternity's secrets and traditions.
