Canterbury, "Becket's Crown" 36 Thirteenth century medallions; notice circular and other forms enclosing the figures. The heavy iron bars needed to support the great weight of lead are skilfully adjusted to the design. The world-famous shrine stood in the centre of this space. Tombof Black Prince in foreground, and above it armour he wore at Crécy. Lincoln, Rose Window 56 Tracery unusual in that it does not radiate from centre. Quantity of greenish grisaille used emphasises leaf-like design. Thirteenth century medallions in the tall lancets below. York Minster, "Five Sisters" 62 Softly toned grisaille, with delicate patterns in faint colour. Of its type unsurpassed in the world. Note difference between mellow strength of this glass and thinness of modern glazing in upper tier of lancets. Map of Decorated Tour 76 York Minster, Chapter-House 78 Note the grouping together in each embrasure of five narrow lights below gracefully elaborated tracery openings. Later on, in the Perpendicular period, these traceries lose their individuality, become stiffly regular, and part of the window below. Tewkesbury Abbey, Choir 100 A rare example of rounded apse, generally replaced in England by a square-ended chancel. Chief charm of these windows is their rich colouring. Wells, "Golden Window" 116 Notice graceful setting, permitting a glimpse through into the Lady chapel beyond. The large Tree of Jesse, rising from the loins of the patriarch, is portrayed in colours of almost barbaric richness. Exeter, East Window 122 Perpendicular stone frame, glazed chiefly with very typically decorated figure-and-canopy glass preserved from the earlier and smaller window. Below and beyond appears the Lady chapel. Map of Perpendicular Tour 140 Oxford, New College Antechapel 144 Transition window, presented by William of Wykeham, Founder of the College. Stone frames are already Perpendicular: note the "pepper-box" tracery lights. The glazing, as usual, lags behind the architecture, and, because of its strong colour and flat drawing, is more Decorated than Perpendicular. Gloucester, Choir 162 Great east window commemorative of knights who fought at Crécy. Backgrounds of pink and soft blue. Tracery lights no longer differentiated from window below, as during Decorated period. Note elaborate masking of earlier walls by later Perpendicular work.
