"All these features bear a close affinity to the decorated work of the nave of York Minster, erected about 1400. The flying buttresses, with pinnacles enriched with crockets and foliaged finials; the niches, with their elaborate canopies and corbels composed of figures of monks and angels; the statues which formerly filled the niches, of which very few now remain; the decorated tracery of the south transept window, and the whole character of the work, both in its general scope and in its details, is of fine decorated design, and vividly recalls that of York, Beverley, and other English examples. It is not improbable that some parts of the nave and transept were erected during the period between the death of King Robert Bruce and the invasion of Richard II. It should be mentioned that Bruce's bequest was not all received till 1399, and the operations also probably proceeded slowly. The doorway in the south wall of the south transept is apparently an insertion in older work."[462] The south chapels of the nave have apparently been added during the repairs in the earlier part of the fifteenth century; the buttresses were probably executed towards the middle of that century, and the east one contains the arms of Abbot Hunter.[463] There is a distinct change in the transept's design from that of the nave, as if the former had been added to the latter at a later period.[464] The east wall and the other eastern parts of the choir are more recent than the nave, and probably this portion of the church had been more damaged by Richard II. than the nave, and required to be almost wholly rebuilt. The style here corresponds closely with the "perpendicular" of England which prevailed in the fifteenth century.[465] The great eastern window is exceptional and unique, and has more of the character of perpendicular than any other style. Scott, referring to it, has described the moon as shining Through slender shafts of shapely stone, By foliaged tracery combined; Thou would'st have thought some fairy's hand, Twixt poplars straight, the osier wand, In many a freakish knot, had twined; Then framed a spell, when the work was done, And changed the willow-wreaths to stone.
