Books in the Art and Imagination series

The spiral is the natural form of growth, and has become, in every culture and in every age, man's symbol of the progress of the soul towards eternal life. As the inward-winding labyrinth, it constitutes the hero's journey to the still center where the secret of life is found. As the spherical vortex, spiraling through its own center, it combines the inward and outward directions of movement.

Discusses the mythological properties assigned to geometric forms, and covers the Golden Section, gnomonic spirals, music, and the squaring of the circle.
