Historical Context
Editorially reviewedThe emblem belongs to the institutional and ritual culture of modern Freemasonry and appears on lodge furnishings, certificates, jewels, buildings, memorials, and personal insignia. Its documented Masonic use should not be conflated with modern conspiracy claims.
Provenance: Squares and compasses were builders’ tools long before modern Freemasonry. Their combined form became an identifying emblem of organised speculative Freemasonry during the eighteenth century, although its precise origin is uncertain.
Context note: Used by living Masonic bodies; exact arrangement, the presence of the letter G, and ritual interpretation vary between jurisdictions.
