Geometry of pre-revolutionary Virginia architecture

Virginia architecture of the seventeenth and eighteenth centuries prior to the American Revolution has distinctive geometries which determine proportion. The square, root-two rectangle and equilateral triangle are the figures which establish most proportions. Plans and elevations underwent a development based on a rational method of incorporating the figures into a coherent building. This investigation establishes the use of geometry as a starting point for the culmination of many elements which together composed a building.
