Quadrivium: The Four Classical Liberal Arts of Number, Geometry, Music, & Cosmology

Number, geometry, music and cosmology. What do these four things have in common? They're the 4 schools of liberal arts covered in the curriculum of Quadrivium. Bringing these topics of study together for the first time in centuries, you'll learn how these for subjects relate to each other (ie. music is time and number, geometry is space and number, cosmology is time, space and number). With beautiful illustration to accompany the dense knowledge, Quadrivium is not only a great resource, but a compact, beautiful book to flip through.
