The Deeper Symbolism of Freemasonry from The Meaning of Masonry by Walter Leslie Wilmshurst.

“I am acquainted, for instance, with an Egyptian ceremonial system, some 5,000 years old, which taught precisely the same things as Masonry does, but in the terms of shipbuilding instead of in the terms of architecture. But the terms of architecture were employed by those who originated modern Masonry because they were ready to hand; because they were in use among certain trade-guilds then in existence; and lastly, because they are extremely effective and significant from the symbolic point of view.” [via]
