Cathedral Forge And Waterwheel

The authors shatter the popular myth that nothing of significance happened between 400 AD and 900 AD. Transportation was improved by the invention of harnesses, horse shoes, stirrups, the mariner's compass, round bottom ships, and systems of multiple masts. Water clocks and systems of weights and measures made their way to Europe from the Far East. Spinning wheels and printing presses were invented and became part of popular culture. The inventions, their inventors, and the impact on daily life are discussed. Illustrated with black and white photos. Annotation copyright by Book News, Inc., Portland, OR
