v.3. Grain In The Stone. Man splits a stone and reassembles the pieces to build a wall, a cathedral, a city. From the Greek temples of Paestum and the cathedrals of medieval France to modern Los Angeles, this film expresses humanity's faith and fancy as architect and builder.
v.4. The Hidden Structure. The Shang bronze craftsmen of China and the Samurai swordsmith of Japan are the starting point for this journey, which leads from the beginnings of chemistry to Dalton's atomic theory and our knowledge of the elements.
v.5. Music of the Spheres. Traces the evolution of mathematics and explores the relationship of numbers to musical harmony, early astronomy and perspective in painting. It follows the spread of Greek ideas through the courts and bazaars of the Islamic Empire to Moorish Spain and Renaissance Europe.
