The interrogatories of Craft Masonry are said to have been penned by William Preston and appear in the ritual workings of the Entered Apprentice Degree sometime after 1772. Prior to this, the preparation room was used for different purposes. In the earliest days of Speculative Masonry, the candidate was “made” a Mason in the preparation room by having the obligations administered to him by the Master before he ever stepped foot into the lodge. This was the case during the late 17th century period and remained common through the first two decades of the 1800’s.
As degree workings became more formalized, the “making ceremony” was moved into the lodge room itself and the anteroom became the waiting area for the candidate while the Master opened the lodge. Once the lodge was opened, the Master asked if anyone was in waiting to be “made.” The Wardens and the proposer retired to prepare the candidate. He was relieved of his metals, asked some basic questions such as name, occupation, and place of residence, and then left to his own reflections for at least half an hour. His proposer sat with him, and he was not allowed to talk. Guards (likely the deacons) stood near with swords drawn.
While all this was taking place, the lodge set up its trestleboard, or set of figures drawn into the floor with charcoal and chalk, set in an oblong square.
