This group’s buildings contain three “immovable” and three “movable” jewels, such as the emblem-decorated “trestle-board.” Confederate general Albert Pike collected essays about this group into a book about the Morals and Dogma of one of its Rites. Albert (10[1])Mackey documented twenty-five “landmarks” of this group, including their separation into three “degrees” (10[2])and their (10[1])belief (10[1])in a subordinate (10[1])of Solomon (10[1])named Hiram Abiff. (10[5])The letter “G” (10[2])is sometimes placed (10[2])in the center (10[4])of the (10[1])“square (10[1])and (10[1])compasses” (10[3])symbol (10[6])used (10[1])by (10[1])this (10[2])group. (10[11])This (10[1])group’s “operative” (10[2])origins (10[1])gave way (10[1])to a “speculative” (10[1])focus on symbols such as the Eye (10[1])of Providence. (10[3])A (10[1])“Grand Master” oversees (10[1])meetings for (-5[1])members of this group (10[1])at “Grand Lodges.” For 10 points, name this fraternal organization originating from guilds of stoneworkers.
