Geometry underlies the structure of all things - from galaxies to molecules. Each time a geometrical form is created, an expression of this universal oneness is made, and from the dawn of time religious structures have expressed this unity in their every detail. In this absorbing history, the applications of sacred geometry are examined and the full extent of its practise is revealed. Sacred geometry is responsible for the feeling of awe generated by a gothic cathedral as well as the 'rightness' of a Georgian drawing-room. The rise and fall of this transcendent art is traced from megalithic stone circles to Art Nouveau and reveals how buildings that conform to its timeless principles mirror the geometry of the cosmos.
