The Map of Knowledge

The Map of Knowledge traces how three ancient texts on mathematics, astronomy, and medicine survived through the Middle Ages. The book follows these scientific manuscripts from Alexandria in the 6th century through seven cities across the Mediterranean and Middle East, ending in Renaissance Venice. Nine chapters detail the transmission of knowledge through cultural centers including Baghdad, Córdoba, Toledo, Salerno, and Palermo. The narrative focuses on the scholars, translators, and book collectors who preserved and translated these classical works during periods of both stability and upheaval. Moller examines how Arab, Jewish, and Christian communities worked to safeguard and advance scientific understanding across cultural boundaries. The book incorporates historical context about the cities themselves, including their politics, architecture, and daily life. Through this journey across centuries and civilizations, the book demonstrates how human knowledge depends on networks of people dedicated to preserving and building upon the discoveries of the past. The survival of these texts reveals the persistence of intellectual curiosity despite war, plague, and cultural change.
