The ancient and accepted Scottish rite, in thirty-three degrees
A Freemasonry text from 1881, published in New York by its author, Robert B. Folger, for members of the Scottish Rite. The pictures are rotated genealogical charts of rope-bordered triangles and boxes linking councils, consistories and grand bodies by lines and dates. A designer could take their tidy hierarchical diagram structure, tracing-board geometry and sepia linework for organisational chart layouts.
