With an estimated four million members worldwide, Freemasonry remains the largest fraternal organization in the world, but "the Craft" is poorly understood. Exploring the organization's fascinating visual culture, the 300 illustrations included here showcase the range of highly symbolic paintings, manuscripts, tracing boards, ritual swords, furniture, architecture, and ceremonial regalia. A member himself, W. Kirk MacNulty provides the historical and philosophical background of the order, including the Knights Templar, the medieval stonemasons' guilds, and various esoteric traditions.
