Starred Review. Marchant, editor of New Science, relates the century-long struggle of competing amateurs and scientists to understand the secrets of a 2000-year-old clock-like mechanism found in 1901 by Greek divers off the coast of Antikythera, a small island near Tunisia. With new research and interviews, Marchant goes behind the scenes of the National Museum in Athens, which zealously guarded the treasure while overlooking its importance; examines the significant contributions of a London Science Museum assistant curator who spent more than 30 years building models of the device; and the 2006 discoveries made by a group of modern researchers using state-of-the-art X-ray. Beneath its ancient, calcified surfaces they found "delicate cogwheels of all sizes" with perfectly formed triangular teeth, astronomical inscriptions "crammed onto every surviving surface," and a 223-tooth manually-operated turntable that guides the device. Variously described as a calendar computer, a planetarium and an eclipse predictor,Marchant gives clear explanations of the questions and topics involved, including Greek astronomy and clockwork mechanisms. For all they've learned, however, the Antikythera mechanism still retains secrets that may reveal unknown connections between modern and ancient technology; this globe-trotting, era-spanning mystery should absorb armchair scientists of all kinds.

Discovered a century ago in an ancient Mediterranean shipwreck, the Antikythera mechanism instantly attracted scientific interest. It had gears, which was and remains unique among artifacts from Greco-Roman civilization. So begins Marchant’s mystery about the object, a tale that ends in triumph but not before inveigling individuals who not only puzzled over the device but also became obsessively devoted to figuring it out. Tantalized by the Antikythera mechanism, scholar Derek de Solla Price felt it was the clue with which he could rewrite the history of technology. Price’s conclusions, however, were challenged by a museum curator of Industrial Revolution technologies; he was Michael Wright, who emerges here as the David among academic Goliaths who, by the early 2000s, were closing in on a conclusive interpretation of the Antikythera mechanism. By then, archaeological evidence dated the ship on which it sank to between 70 and 60 BCE and suggested its connection to the astronomer Hipparchus. Science readers will be entranced by Marchant’s vibrant depiction of the characters in this remarkable story of ancient technology. --Gilbert Taylor

The final section gives an intriguing vision of how this device changes our views on History and the talents of Greek scientists.
Decoding the Heavens chronicles the Antikythera mechanism from its discovery, to its lying deteriorating in museum storage, to someone finally realizing its significance. If you thought the ancient Greeks were all pretty statues and buildings, then this book is a real eye opener. Jo Marchant covers the modern history of the mechanism and also speculates on its ancient history, its creation and subsequent loss/saving in a shipwreck. Bronze and brass were a valuable war materiel, I wonder what other artifacts have been lost to be melted down to make the next army's weapons?
If you're interested in technology, astronomy, and the ancient Greeks then you are in for a treat.
On another subject, reading the details about how some scientists try to keep their research a secret, how stingy museums are with access to their artifacts, etc. is not very flattering. But I believe that's the way it is.
If you enjoy the history of science and technology or just enjoy a good adventure book, I highly recommend this book.
It's a great focus on historical events, which is all I care about it. The author presents some good points of view on her take of it and then some I definitely don't agree with. But it's a great book. I couldn't put it down.
