On the edge of medieval maps, monsters roam. In the west, pilgrims take well-traveled roads to Rome and Compostela. In the east, Old Testament history unfolds. And at the center, in the city of Jerusalem, Jesus saves the world. In A World Transformed, Lisa Deam takes us on an incredible journey through medieval maps. Despite their curious appearance, these maps, as Deam shows, are surprisingly modern. In their monstrous, marvelous sights lie treasure troves of wisdom to guide twenty-first-century Christians on their walk with God. Each chapter in this geographical journey links medieval maps to biblical concepts and spiritual practices that transform our faith and our world.
