V. Immediately that the nave was roofed in, the canons commenced to rebuild the eastern limb. Meanwhile architectural fashions had changed. While the York people were lingering over their Geometrical nave, a whole architectural period had passed away, leaving behind few traces at York except in the west front. When the new choir was commenced in 1361, the Curvilinear style had disappeared before the new Perpendicular style, invented at Gloucester and taken up by Bishop Edingdon at Winchester. The style, however, was still new, and though the Winchester work is purely Perpendicular, the York design still retains in the window tracery reminiscences of the flow of curve that Edingdon and Wykeham had replaced by grilles of horizontal and vertical bars. Only the eastern part of Archbishop Roger’s Transitional work was at first pulled down, the services going on without interruption in the western bays. The four new eastern bays—designed as a retro-choir, the altar standing originally one bay more to the west than at present—may be distinguished at once externally by the unusual feature of having an external instead of an internal arcade to the clerestory; this gives a fine play of light and shadow. Then the five western bays were built, two bays as sanctuary, three as choir. Owing to the continuation of the high roofs to the extreme east end of the cathedral, there is little of the picturesqueness of the eastern terminations of Wells and Salisbury, but there is spaciousness, dignity and majesty. Here also the canons had not the money—perhaps not the courage—to put up a high vault of stone. Nave, eastern limb, and transept (the vault of which is of the fifteenth century) were all vaulted in wood. The punishment was long in coming, but it came at last. The wooden vault of the choir, the stalls and the organ, were burnt down by a lunatic in 1829; and that of the nave by a plumber in 1840. The finest feature in the choir is the tall transeptal bays, suggested by and built on the foundations of Archbishop Roger’s flanking towers. The whole eastern limb was finished _c._ 1420. Then came the central tower, 1410-1433; the south-west tower, 1433-1447; the north-west tower, 1465-1474; the organ screen, 1475-1505. [Illustration: FROM SOUTH-WEST.] In 1472 the completion of the great works commenced _c._ 1230 was near at hand, and a solemn consecration of the rebuilt cathedral was held. The Norman and Transitional cathedral had disappeared; its successor occupied a century and a half in building. [Illustration: SOUTH CHOIR.]
