Albert Mackey,
The Symbolism of Freemasonry — Chapter XIII
(1882)
“ A masonic lodge is, therefore, a symbol of the world.This symbol is sometimes, by a very usual figure of speech, extended, in its application, and the world and the universe are made synonymous, when the lodge becomes, of course, a symbol of the universe. But in this case the definition of the symbol is extended, and to the ideas of length and breadth are added those of height and depth, and the lodge is said to assume the form of a double cube. ”
