Looks at man and nature as shapers of the environment. Locations include: Arizona's Canyon de Chelly, whose breathtaking chasmic formation was hewn by the elements; Peru's Machu Picchu, a terraced city built by the Incas at the height of their empire; in Segovia, Spain, a prodigious half-mile span of granite arches built by the Romans about 100 AD. Dr. Bronowski also studies the Gothic beauty of Rheims Cathedral and discusses ancient mathematical instruments.
