About Time: A History of Civilization in Twelve Clocks
by: David Rooney

Hardcover. NY, W. W. Norton & Company, 1st, 2021, Book: Very Good, Dust Jacket: Very Good, Hardcover in a bright dust jacket, 271 pages, b&w illustrations. 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. Rooney 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. Clean copy.
