Gerbert d’Aurillac (ca 945–1003) was a 10th-century French churchman and scholar who was named Pope Sylvester II in the year 999. Presumably unlike other popes, he was fascinated by mathematics. He studied it as a young man in the medieval Spanish March; he taught it at the Cathedral School at Rheims; he even wrote a well-known textbook in geometry. He was one of the first people in Western Europe to learn about Hindu-Arabic numerals, and he developed an abacus for working with them.
