In it, we follow them from sixth-century Alexandria to ninth-century Baghdad, 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.
