The Map of Knowledge

'Violet Moller brings to life the ways in which knowledge reached us from antiquity to the present day in a book that is as delightful as it is readable.' – Peter Frankopan, author of The Silk Roads In The Map of Knowledge Violet Moller traces the journey taken by the ideas of three of the greatest scientists of antiquity – Euclid, Galen and Ptolemy – through seven cities and over a thousand years. In it, we follow them from sixth-century Alexandria to ninth-century Baghdad. From Muslim Cordoba to Catholic Toledo. From Salerno’s medieval medical school to Palermo, capital of Sicily’s vibrant mix of cultures. And – finally – to Venice, where that great merchant city’s printing presses would enable Euclid’s geometry, Ptolemy’s system of the stars and Galen’s vast body of writings on medicine to spread even more widely. In tracing these fragile strands of knowledge from century to century, from east to west and north to south, Moller also reveals the web of connections between the Islamic world and Christendom. Connections that would both preserve and transform astronomy, mathematics and medicine from the early Middle Ages to the Renaissance. Vividly told and with a dazzling cast of characters, The Map of Knowledge is an evocative, nuanced and vibrant account of our common intellectual heritage. 'An endlessly fascinating book, rich in detail, capacious and humane in vision.' – Stephen Greenblatt, author of The Swerve: How the World Became Modern

After the fall of Rome, as civilizations collapsed and libraries burned, ancient knowledge that would eventually fuel the Renaissance was at risk of being lost. This thrilling history tracks three crucial books as they were passed hand to hand through seven cities during a perilous thousand-year journey of survival. After the great library at Alexandria was destroyed, Baghdad, Cordoba, Toledo, Salerno, and Palermo were rare outposts of knowledge in a dark world, where dedicated scholars collected, translated, and shared texts . Violet Moller's The Map of Knowledge takes us into the sparkling intellectual life that flourished there, highlighting the crucial role played by Arab scholars in improving the cornerstone ideas of Western thought. She shows us how foundational works on math, astronomy, and medicine by Euclid, Ptolemy, and Galen eventually reached Venice, the major center of scientific printing, where their legacy was assured--having been rescued by the passionate curiosity of generations of readers.
