... Still on the subject of glass, one small panel in the Clopton chantry chapel, at the far east of the church, is a very rare depiction of the crucifixion. Dating from 1350 this shows Christ crucified on to a cross made from while lilies. The lily was often used as a symbol of purity and was often pictured in scene containing the Virgin Mary.
