Strasbourg Cathedral’s astronomical clock is one of the most famous monuments to Time in the world. No other clock has been described and appreciated so often and in such a myriad of ways. There were three clocks built consecutively within the cathedral: the earlier fourteenth century clock has left little trace; a second clock was realized in 1570-1574; while the nineteenth century clock began as a proposal for repairs, but was intended by its maker as a replacement clock. This book gives a detailed outline of the artistic and technical components of the second clock, much of which survives, and it describes the astronomical indications and its underlying conceptual framework. The author has discovered a hitherto disregarded contemporary statement that the clock displays four ways of determining the ascendant as described by Ptolemy. He also shows that the Strasbourg clock is the result of a highly original reception of the architectural theory of Vitruvius and other mathematical and mechanical texts of Late Antiquity. Revised and updated translation from the German edition Die Straßburger Münsteruhr: Funktion und Bedeutung eines Kosmos-Modells des 16. Jahrhunderts. Published by GNT-Verlag in 1993.

One of Smithsonian Magazine's Ten Best History Books of 2021 A captivating, surprising history of timekeeping and how it has shaped our world. 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.

“An enchanting, ghostly story that had me in its grip until the last page."—Jennifer A. Nielsen, New York Times and USA Today best-selling author of The False Prince “Keep calm and carry on.” That’s what Katherine Bateson’s father told her, and that’s what she’s trying to do: when her father goes off to the war, when her mother sends Kat and her brother and sister away from London to escape the incessant bombing, even when the children arrive at Rookskill Castle, an ancient, crumbling manor on the misty Scottish highlands. But it’s hard to keep calm in the strange castle that seems haunted by ghosts or worse. What’s making those terrifying screeches and groans at night? Why do the castle’s walls seem to have a mind of their own? And why do people seem to mysteriously appear and disappear? Kat believes she knows the answer: Lady Eleanor, who rules Rookskill Castle, is harboring a Nazi spy. But when her classmates begin to vanish, one by one, Kat must uncover the truth about what the castle actually harbors—and who Lady Eleanor really is—before it's too late.
