In Decoding the Heavens, Jo Marchant tells for the first time the full story of the 100-year quest to decipher the ancient Greek computer known as the Antikythera Mechanism. Along the way she unearths a diverse cast of remarkable characters and explores the deep roots of modern technology in ancient Greece and the medieval European and Islamic worlds. At its heart, this is an epic adventure and mystery, a book that challenges our assumptions about technology through the ages.
The book describes the finding and investigation of one of the most enigmatic ancient artifacts. Many theories have swirled around it (Aliens!) but in 2006 a group of math, astronomy and imaging specialists finally determined the purpose of the existing fragments.
She does a great job of describing the initial find and the first enthusiastic but erroneous interpretations of what the device was. All of the standard academic personalities are here--the Dreamer, the Enthusiastic Amatuer, the Double-crosser, the Possessive Curators, the serendipitous encounters.
I was particularly impressed by how she explained the subtleties of translating irregularities of lunar and solar motion into clockwork. Her descriptions of the actual bronze fragments were less clear, but since they are apparently barely recognizable as gears this is easy to forgive. She also describes future possibilities for investigation since there may have been more to the device than was recovered.
I was less happy with the performance. The reader has a whimsical delivery that the text really doesn't support, but her reading is accurate and easy to understand.
I would recommend this to someone interested in classical Greece and science history in general.
