Peter Lombard, a twelfth-century theologian, authored one of the first Western textbooks of theology, the Book of Sentences. Here, Lombard logically arranged all of the major topics of the Christian faith. His Book of Sentences received the largest number of commentaries among all works of Christian literature except for Scripture itself. Now, notable Lombard scholar Philipp W. Rosemann examines this text as a guiding thread to studying Christian thought throughout the later Middle Ages and into early modern times.

This is the second title in a series called Rethinking the Middle Ages, which is committed to re-examining the Middle Ages, its themes, institutions, people, and events with short studies that will provoke discussion among students and medievalists, and invite them to think about the middle ages in new and unusual ways. The series editor, Paul Edward Dutton, invites suggestions and submissions.
