Introducing “Sacred Symbols” Collection by C.7 Design Studio. Here you will find a unique design, featuring a symbol of the masonic 4th Degree: Secret Master or Master Traveller . Freemasonry is a fraternal organisation that arose from obscure origins in the late 16th to early 17th century. Freemasonry now exists in various forms all over the world, with a membership estimated at around six million. The fraternity is administratively organised into independent Grand Lodges or sometimes Orientates, each of which governs its own jurisdiction, which consists of subordinate (or constituent) Lodges. There are also appending bodies, which are organisations related to the main branch of Freemasonry, but with their own independent administration. The lessons of the 4° are secrecy, obedience, and fidelity. Your first steps into our sanctuary are duty, reflection and study. They teach us to honour those relationships to God, family, country, Masonry. The apron is white and black, with a letter "Z" and all-seeing eye. The jewel is an ivory key with the letter "Z" on the wards.
