About this book
Clocks did not descend from sundials, argues Derek J. de Solla Price. Their true ancestors, he says, were the complex astronomical machines built since Hellenic times to show the motions of the heavens. This Smithsonian paper follows that line over 2,000 years and three continents, with sections on gearing, the early mechanical clock, perpetual motion devices before de Dondi, and the magnetic compass as a traveler from China. Price is also known for his study of the Antikythera mechanism.
