"The Lost Symbol" Magic Squares and the Masonic Cipher One of the really interesting exercises in Arithmetic for Masons is the building of Magic Squares. They show up in the work of Durer and play a role in Dan Brown’s book, The Lost Symbol. This is an exceptional explanation of how to construct a Magic Square as well as a discussion of their use in making a cipher and also of Brother Benjamin Franklin’s magic square. It turns out Franklin’s does not truly qualify as a magic square, but is noteworthy none-the-less. St. Michael's Ministry of Gnosis serves as a sanctuary for literature, religion, scientific research, history, gnosis, and art. Our main practice is the collection and application of knowledge.
