Sumptuously illustrated with dazzling objects, this publication explores the ways art and science worked hand in hand in the Middle Ages and Renaissance.

Through the manipulation of materials, such as gold, crystal, and glass, medieval artists created dazzling light-filled environments, evoking, in the everyday world, the layered realms of the divine. While contemporary society separates science and spirituality, the medieval world harnessed the science of light to better perceive and understand the sacred. From 800 to 1600, the study of astronomy, geometry, and optics emerged as a framework that was utilized by theologians and artists to comprehend both the sacred realm and the natural world.

Through essays written by contributors from the fields of art history, the history of science, and neuroscience, and with more than two hundred illustrations, including glimmering golden reliquaries, illuminated manuscripts, rock crystal vessels, astronomical instruments, and more, Lumen cuts across religious, political, and geographic boundaries to reveal the ways medieval Christian, Jewish, and Islamic artists, theologians, and thinkers studied light. To convey the sense of wonder created by moving light on precious materials, a number of contemporary artworks are placed in dialogue with historic objects.

This volume is published to accompany an exhibition on view at the J. Paul Getty Museum at the Getty Center from September 10 to December 8, 2024.

Based on a collaboration between historians of Chinese and European politics, this volume offers a first comprehensive overview of current research on political communication in middle-period European and Chinese history. The chapters present new work on the sources and processes of political communication in European and Chinese history partly through juxtaposing and combining formerly separate historiographies and partly through direct comparison. Contrary to earlier comparative work on empires and state formation, which aimed to explain similarities and differences with encompassing models and new theories of divergence, the goal is to further conversations between historians by engaging regional historiographies from the bottom up.
