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.
Kirkus
"A thoroughly engrossing account of the Dark Ages and one of its Popes, both far less dark than popular histories teach.... The years around 1000 CE seem to be every medieval historian's favorite era, but Brown's welcome addition to the genre provides a lively, eye-opening portrait of a sophisticated Europe whose intellectual leaders showed genuine interest in learning."
Science Writers Magazine
"As she reconstructs the strangely illuminated Europe of the Dark Ages, Brown reminds readers that the major conflicts in our world today--between Christianity and Islam, between religion and science--are products of our own age, not historical inevitabilities."
Booklist
"As readably knowledgeable about Gerbert's political fortunes as about his intellectual influence, Brown is a lively narrator and interesting interpreter of Gerbert's life and world. This portrait gives both the science and the history audiences something to talk about."
The New York Journal of Books
"Ms. Brown's easily readable history draws the reader into a world of political intrigue, the excitement of introducing the abacus and astrolabe to Europe, and the shaky ground that surrounding the broader culture of Europe around 1000. Her book is a useful reminder that clear and well-reasoned history is by no means simplistic. The story of d'Aurillac's life and papacy shows a medieval milieu more complex than oft portrayed."
Marilyn Yalom, author of Birth 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 of Femme Fatale: Love, Lies, and the Unknown Life of Mata Hari
"Nancy Marie Brown again uses her extraordinary ability to bring medieval time to life in The 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."
