Most general histories of technology are Eurocentrist, focusing on a main line of Western technology that stretches from the Greeks is through the computer. In this very different book, Arnold Pacey takes a global view, placing the development of technology squarely in a world civilization. He portrays the process as a complex dialectic by which inventions borrowed from one culture are adopted to suit another. For thousands of years, people of all cultures have made and used clocks, from the city sundials of ancient Rome to the medieval water clocks of imperial China, hourglasses fomenting revolution in the Middle Ages, the Stock Exchange clock of Amsterdam in 1611, Enlightenment observatories in India, and the high-precision clocks circling the Earth on a fleet of GPS satellites that have been launched since 1978. Clocks have helped us navigate the world and build empires, and have even taken us to the brink of destruction. Elites have used them to wield power, make money, govern citizens, and control lives—and sometimes the people have used them to fight back.Through the stories of twelve clocks, About Time brings pivotal moments from the past vividly to life. Historian and lifelong clock enthusiast David Rooney takes us from the unveiling of al-Jazari’s castle clock in 1206, in present-day Turkey to the Cape of Good Hope observatory at the southern tip of Africa, where nineteenth-century British government astronomers moved the gears of empire with a time ball and a gun to the burial of a plutonium clock now sealed beneath a public park in Osaka, where it will keep time for 5,000 years.Rooney shows, through these artifacts, how time has been imagined, politicized, and weaponized over the centuries—and how it might bring peace. Ultimately, he writes, the technical history of horology is only the start of the story. A history of clocks is a history of civilization. Originally published between 1920-70, The History of Civilization was a landmark in early twentieth century publishing. It was published at a formative time within the social sciences, and during a period of decisive historical discovery. The aim of the general editor, C.K. Ogden, was to summarize the most up to date findings and theories of historians, anthropologists, archaeologists and sociologists.
