Finding and Recording Geometrical Symbols in Historic Buildings

Square 8.25 inches x 8.25 inches / 8 pages / full colour

This ePamphlet shows examples of some geometrical symbols found in historic buildings. The text explains how to find these delicately scribed and often elusive symbols, how to record them accurately without damaging them and how to preserve them for posterity. The text also explains how the symbols are often simplified geometrical codes for the plan, section and elevation of the specific buildings on which they are found.
