Designed by the “Father of Sienese Painting,” Duccio di Buonisegna in 1287, the great stained-glass window of Siena Cathedral is a celebration of the city’s spiritual queen – the Blessed Virgin Mary! The window is divided into nine segments. The three central segments depict the “Coronation/Assumption/Dormition of the Virgin Mary” in descending order, while the four “corner” segments depict the “Four Evangelists.” To either side of the central “Assumption” are Siena’s four patron saints. Today, the original stained-glass window is housed in the Museo dell’Opera del Duomo (the Cathedral Museum) for conservation, while a copy sits in its original location in the apse of Siena Cathedral. Buona visione!
