Medieval Christians knew the past primarily through what they saw and heard. History was reenacted every year in ritual observances particular to each place and region and rooted in the legends of local saints. This richly illustrated book explores the layers of history found in the cult of the Virgin of Chartres as it developed in the eleventh and twelfth centuries. Focusing on the major relic of Chartres Cathedral, the Virgin’s gown, and the Feast of Mary's Nativity, Margot Fassler employs a wide range of historical evidence including local histories, letters, obituaries, chants, liturgical sources, and reports of miracles, leading to a detailed reading of the cathedral's west façade. This interdisciplinary volume will prove invaluable to historians who work in religion, politics, music, and art but will also serve as a guidebook for all interested in the history of Chartres Cathedral.
