 The central oculus shows the Virgin and Child and is surrounded by twelve small petal-shaped windows, 4 with doves (the 'Four Gifts of the Spirit'), the rest with adoring angels carrying candlesticks.Beyond this is a ring of twelve diamond-shaped openings containing the Old Testament Kings of Judah, another ring of smaller lozenges containing the arms of France and Castille, and finally a ring of semicircles containing Old Testament Prophets holding scrolls.The presence of the arms of the French king (yellow fleurs-de-lis on a blue background) and of his mother, Blanche of Castile (yellow castles on a red background) are taken as a sign of royal patronage for this window.
