The three upper-central panels (14, 17 and 20), representing the Virgin carrying the Christ Child on her lap in a strongly frontal pose (the so-called Sedes Sapientiae or 'Throne of Wisdom' format) are mid-12th century in date - rare survivors from Fulbert's glazing programme, possibly from the eastern axial chapel. They survived the fire of 1194 and were later re-fitted in this window, which otherwise dates from c.1220. The 13th century saw many such examples of earlier panels being re-used, as if their supposed antiquity (in fact most were little more than a generation or two old) gave them a special sanctity. From the 15th century onwards such recycled panels became known as Belles verrieres - many such exist though this is perhaps the most famous. As with the west windows, although the roots of the Virgin and Child panels are 12th century, they have been so heavily restored, in the 13th, 14th and 19th centuries, that relatively little of the original glass survives (for example, of the Virgin's halo, only two small fragments are original).
