Inside Christian churches, natural light has long been harnessed to underscore theological, symbolic, and ideological statements. In this volume, twenty-four international scholars with various specialties explore how the study of sunlight can reveal essential aspects of the design, decoration, and function of medieval sacred spaces. Themes covered include the interaction between patrons, advisors, architects, and artists, as well as local negotiations among competing traditions that yielded new visual and spatial constructs for which natural light served as a defining and unifying factor. The study of natural light in medieval churches reveals cultural relations, knowledge transfer patterns, processes of translation and adaptation, as well as experiential aspects of sacred spaces in the Middle Ages.

Using light as fil rouge reuniting theology and ritual with the architecture, decoration, and iconography of cultic spaces, the present study argues that the mise-en-scene of fifth-century baptism and sixth-century episcopal liturgy was meant to reproduce the luminous atmosphere of heaven. Analysing the material culture of the two sacraments against common ritual expectations and Christian theology, we evince the manner in which the luminous effect was reached through a combination of constructive techniques and perceptual manipulation. One nocturnal and one diurnal, the two ceremonials represented different scenarios, testifying to the capacity of church builders and willingness of Late Antique bishops to stage the ritual experience in order to offer God to the senses.
