"Without the rich spiritual and literary legacy of the Middle Ages, C. S. Lewis would not have matured into the great apologist, essayist, and fiction writer that he became. Dante scholar Jason Baxter is just the right person to open up that legacy for modern readers and trace how deeply Lewis was shaped not only by the medieval worldview but by the way the medievals thought and felt and interacted with the spiritual and natural world around them."

"Following closely on his well-received works on Dante and on Christian mysticism, Jason Baxter here opens a window onto the bookshelves and study habits of C. S. Lewis, finding rightly that medieval authors have much more profoundly shaped his imagination and theology than most contemporary criticism has noticed. This well-written volume will be of interest both to seasoned scholars and undergraduate students; for the latter it will prove an invaluable introduction to a rich body of great Christian writing."

"As the author of A Beginner's Guide to Dante's Divine Comedy, Jason M. Baxter is uniquely qualified to guide us through the medieval mind of C. S. Lewis. Those wishing to delve deeper into the ancient roots of Lewis's inspiration and imagination need look no further. Professor Baxter, like Virgil, is a trustworthy guide."

"I am often lamenting about what our culture has lost. C. S. Lewis is one of our sages who revitalizes the premodern world so that we can again reclaim an enchanted vision of reality. In this book, Jason Baxter offers the church what we've longed for—the tools by which Lewis embodied the medieval worldview—so we too can imitate this forgotten way of seeing."

"In this beautifully written book, Jason Baxter invites us to breathe the air of the medieval world that was C. S. Lewis's natural home, providing rich insight into the philosophical and theological imagination that shaped Lewis's thought and writing. But much more, Baxter helps us grasp the urgency Lewis felt to convey the beauty and grandeur of that age to us moderns, who live in a mechanized universe that is robbed of transcendence. This book is a vital resource not only for understanding Lewis and his world but also for making sense of our own."

"C. S. Lewis described himself as a 'dinosaur'—a member of an otherwise extinct species who could still breathe the air of the Middle Ages and could therefore make it come alive for others. Jason Baxter does a great job of surveying and unpacking this whole side of Lewis's work and its sophisticated, sacramental, and symphonic qualities. The result is a thrilling, moving, and even dangerous ride. Welcome to Jurassic Park!"
