Quadrivium - The four classical liberal arts of number, geometry

More about the book

The quadrivium consists of the four liberal arts of number, geometry, music, and cosmology, studied from antiquity to the Renaissance as a way of glimpsing the nature of reality. They synthesize number, space, and time. Geometry is number in space; music is number in time; and comology expresses number in space and time. Number, music, and geometry are metaphysical truths, good and beautiful everywhere at all times. Life across the universe investigates them. They foreshadow the physical sciences. This is the first volume to bring together the quadrivium in many hundreds of years.--Publisher description
