Moller traces the journey taken by the ideas of three of the greatest scientists of antiquity through seven cities and over a thousand years. From Muslim Córdoba 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. Moller 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.
