## Description

The quadrivium-the classical curriculum-comprises the four liberal arts of number, geometry, music, and cosmology. It was studied from antiquity to the Renaissance as a way of glimpsing the nature of reality. Geometry is number in space; music is number in time; and cosmology expresses number in space and time. Number, music, and geometry are metaphysical truths: life across the universe investigates them; they foreshadow the physical sciences.

*Quadrivium* is the first volume to bring together these four subjects in many hundreds of years. Composed of six successful titles in the Wooden Books series-*Sacred Geometry*, *Sacred Number*, *Harmonograph*, *The Elements of Music*, *Platonic & Archimedean Solids*, and *A Little Book of Coincidence*-it makes ancient wisdom and its astonishing interconnectedness accessible to us today.

Beautifully produced in six different colors of ink, *Quadrivium* will appeal to anyone interested in mathematics, music, astronomy, and how the universe works.
