The remarkable story of how medieval Arab scholars made dazzling advances in science and philosophy—and of the itinerant Europeans who brought this knowledge back to the West. For centuries following the fall of Rome, western Europe was a benighted backwater, a world of subsistence farming, minimal literacy, and violent conflict. Meanwhile Arab culture was thriving, dazzling those Europeans fortunate enough to catch even a glimpse of the scientific advances coming from Baghdad, Antioch, or the cities of Persia, Central Asia, and Muslim Spain. T here, philosophers, mathematicians, and astronomers were steadily advancing the frontiers of knowledge and revitalizing the works of Plato and Aristotle. I n the royal library of Baghdad, known as the House of Wisdom, an army of scholars worked at the behest of the Abbasid caliphs. At a time when the best book collections in Europe held several dozen volumes, the House of Wisdom boasted as many as four hundred thousand.  Even while their countrymen waged bloody Crusades against Muslims, a handful of intrepid Christian scholars, thirsty for knowledge, traveled to Arab lands and returned with priceless jewels of science, medicine, and philosophy that laid the foundation for the Renaissance. I n this brilliant, evocative book, Lyons shows just how much “Western” culture owes to the glories of medieval Arab civilization, and reveals the untold story of how Europe drank from the well of Muslim learning. Jonathan Lyons served as an editor and foreign correspondent—mostly in the Muslim world—for Reuters for more than twenty years. He is now a researcher at the Global Terrorism Research Center and a Ph.D. candidate in the sociology of religion, both at Monash University in Melbourne, Australia.

House of Wisdom is a fascinating and picturesque page-turner."—Ian Bremmer, author of The J Curve"Lyons capably delineates the fascinating journey of this knowledge to the West, highlighting a few key figures, including Adelard of Bath, whose years spent in Antioch paid off grandly in bringing forth his translations of Euclid and al-Khwarizmi; and Michael Scot, science adviser and court astrologer to Frederick II, who translated Avicenna and Averroes."—Kirkus Reviews “Sophisticated and thoughtful…In The House of Wisdom, Jonathan Lyons shapes his narrative around the travels of the little-known but extraordinary Adelard of Bath, an English monk who traveled to the East in the early 12th century and learned Arabic well enough to translate mathematical treatises into English…. Mr. Lyons's narrative is vivid and elegant.” –Eric Ormsby, Wall Street Journal - from Amzon
