ReviewsKeith Devlin, Stanford University professor and author ofFibonacci's Bridge of Numbers: the Medieval Visionary and the Book that Launched the Modern World "Nancy Marie Brown's book provides a fascinating, well researched, in depth study of the life and times of one of the key figures who brought modern arithmetic into Western Europe." Marilyn Yalom, author ofBirth of the Chess Queen "This book will change how you think about the so-called Dark Ages. Well-researched, well-written, and vividly illuminating." Pat Shipman, Professor of Anthropology at the Pennsylvania State University and author ofFemme Fatale: Love, Lies, and the Unknown Life of Mata Hari "Nancy Marie Brown again uses her extraordinary ability to bring medieval time to life inThe Abacus and the Cross, in the person of the 'Scientist Pope' Gerbert of Aurillac (later Pope Sylvester II). Working from sparse records, Brown manages to tell us of the remarkable scholar, brilliant mathematician, and inveterate punster who loved both his holy orders and luxurious living. She shows us a time in which the route to God lay through the study of science and math and when intellectual developments flowed across the boundaries of religion and empire in Eurasia. This is a remarkable book that reflects on our modern times on every page." Jeff Sypeck, author ofBecoming Charlemagne "A pleasure to read,The Abacus and the Crossdraws readers into a world of intrigue, superstition, and scholarship. Nancy Marie Brown writes lucidly about math and science, finding important stories in the lives of medieval people who deserve to be widely remembered." , Keith Devlin, Stanford University professor and author ofFibonacci's Bridge of Numbers: the Medieval Visionary and the Book that Launched the Modern World "Nancy Marie Brown's book provides a fascinating, well researched, in depth study of the life and times of one of the key figures who brought modern arithmetic into Western Europe."

SynopsisAn acclaimed science writer tells the story of Pope Sylvester II, the erstwhile mathematician, astronomer, and spy, who brought Islamic science to the West before the year 1000, The medieval Catholic Church, widely considered a source of intolerance and inquisitorial fervor, was not anti-science during the Dark Ages--in fact, the pope in the year 1000 was the leading mathematician and astronomer of his day. Called "The Scientist Pope," Gerbert of Aurillac rose from peasant beginnings to lead the church. By turns a teacher, traitor, kingmaker, and visionary, Gerbert is the first Christian known to teach math using the nine Arabic numerals and zero. In The Abacus and the Cross , Nancy Marie Brown skillfully explores the new learning Gerbert brought to Europe. A fascinating narrative of one remarkable math teacher, The Abacus and the Cross will captivate readers of history, science, and religion alike.
