The term “LEWIS” refers to a form of iron cramp or clamp, which is inserted into a prepared cavity in a stone, by which it may be lowered or lifted. It is also a speculative term used to refer to the son of a Mason, whether born before or after his father’s initiation into the Craft.

The “Lewis” supports his father, and aids his failing strength. An “old country” expression, there are no special privileges afforded a “Lewis”, and he must wait until the age of 21 years before he can be made a Mason. An exception is in Scotland, where he can be initiates at the age of 18 years.
