The right lancet of w.210 contains Saint Thaddeus (Jude), the apostle traditionally invoked in difficult causes. He is shown with a green mantle over ochre tunic, a palette echoing the cool–warm chromatic balance found throughout the south clerestory. Like the others, he holds a book of doctrine, presenting himself not as miracle-worker but as apostolic teacher.
Thaddeus’ features are sharply delineated, with angular jawline, pronounced cheekbones, and crisply painted beard curls, typical of early 13th-century French glass painting in the Loire region.
