Volume II: The Later Middle Ages begins in the late eleventh century. For this new edition, Patrick J. Geary has incorporated more bibliographical information into the introductions to the readings. St. Thomas Aquinas' On the Proof of God's Existence, selections from the Saxon Mirror (Sachsenspiegel), and sources from Poland have been added. A glossary is provided to help with unfamiliar terms. For students who want to dig deeper into the primary sources, secondary readings about the primary sources are listed.
