Arithmetic was one of the seven liberal arts taught in the French schools just before the middle of the twelfth century, and Boethius’s De arithmetica was the principal textbook for this art. This volume provides an edition of a commentary on the De arithmetica; the accompanying introduction identifies the author of the commentary as Thierry of Chartres, and provides a careful consideration of how the commentary reflects his philosophy.
