Drawings and writings by Archimedes, previously thought to have been destroyed, have been uncovered beneath the pages of a 13th-century monk's prayer book. These hidden texts, slowly being retrieved and deciphered by scientists, show that Archimedes' thinking (2,200 years ago) was even ahead of Isaac Newton in the 17th century. Archimedes discovered the value of Pi, he developed the theory of specific gravity and made steps towards the development of calculus. Everything we know about him comes from three manuscripts, two of which have disappeared. The third, currently in the Walters Art Museum, is a palimpsest - the text has been scraped off, the book taken apart and its parchment re-used, in this case as a prayer book. William Noel, the project director, and Reviel Netz, a historian of ancient mathematics, tell the enthralling story of the survival of that prayer book from 1229 to the present, and examine the process of recovering the invaluable text underneath as well as investigating into why that text is so important. Combining intrigue, lost books, academic detection and final revelations which rewrite the history of science and mathematics, The Archimedes Codex will be a major publishing event.

"The Archimedes Palimpsest is the name given to a Byzantine prayer-book which was written over a number of earlier manuscripts, including two unique examples containing works by Archimedes, unquestionably the greatest mathematician of antiquity. Sold at auction in 1998, it has since been the subject of a privately funded project to conserve, image, and transcribe its texts. In this volume the scientists, conservators, classicists, and historians involved in the project discuss in full their techniques and their discoveries. These include new speeches by the classical Athenian orator Hyperides, a lost commentary on Aristotle's Categories from the second or third century AD, and substantial re-readings and reinterpretations of the works by Archimedes. The book discusses the pioneering imaging and post-processing techniques used to reveal the texts, and includes detailed codicological descriptions of all eight manuscripts comprising the Palimpsest. It will be of interest to manuscript scholars, classicists, and historians of science"
