The sudden re-awakening of European civilisation in the 12th century is traced by Sir Kenneth Clarke to its high point - the building of the Cathedral of Chartres.
Sir Kenneth Clark explores the aspirations and achievements of the gothic world, on a journey from a castle on the river Loire in France to the cathedral baptistry at Pisa in Italy.
Kenneth Clarke discusses the importance of light in 17th-century Dutch painting, and the rapid pace of scientific discovery in the London of the Royal Society.
