The Cathedral of Chartres was built for Mary. Her Assumption and Coronation are depicted in several places, including a dedicated window in the center of the cathedral. How can we understand this theme today? What do we actually know about Mary? And what could we know? Sophia-Janet Aleemi addresses these questions and brings a seemingly conventional representation to life. She draws a wide arc that extends beyond the beginnings of Christianity, thus embedding Mary-Sophia in the history of humanity. At the same time, she anchors Mary in her historical places of life, which the author knows from personal experience. This art-historical examination is written in an engaging manner yet leads to the highest heights. In this way, the stained glass window becomes transparent in a spiritual sense, which can be appreciated when viewing the accompanying color plates.
