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.
