The Canon

Seven essays by an architect who read buildings as geometry. Bragdon works through symmetry, polarity and what he calls latent geometry, then applies it to the human body and to music.

Claude Bragdon

A painter and a mathematician measure shells, leaves, wasp nests and Renaissance facades looking for the same proportional rules. Hundreds of diagrams, and the clearest case anyone made for geometry as nature's grammar.

Samuel Colman and C. Arthur Coan

Oliver takes the Pythagorean triangle apart number by number, from the monad and the point up through the decad. A Victorian look at how geometry and number carried meaning in the mystery traditions.

George Oliver

Cook presents B. W. Betts's attempt to draw the growth of consciousness as a series of geometric figures. Strange, rigorous and beautifully diagrammed, with a chapter on the fourth dimension.
