The older surviving portions show some remains of the transition style, but the principal parts of the structure have been carried out in the first pointed style. The remains of the choir piers clearly indicate that that style has prevailed in the choir, and the beautiful entrance to the chapter house gives some idea of the boldness and vigour of the first pointed work which, doubtless, extended throughout the building. The cathedral has been very greatly ruined, but some portions have escaped destruction. Of these the east end wall still stands, but without its gable, and one half of the west end wall is entire. Besides these, the south wall of the nave, the west and south walls of the south transept for a considerable height, portions of other walls and foundations, and certain of the pillars to a few feet above the bases, are all that now survive of this once splendid structure. The east end of the choir, and the south transept and nave as far west as the fourth bay of the nave, show some lingering traces of the Transition style; and in portions of the nave, as far as the cloister doorway in the third bay from the west end, the lower part of the wall half-way up to the window sills, is of the same period. This is evident from the flat band, chamfered at top and bottom, which runs along thus far, and is a characteristic feature of early work. The building of the western portion by Wishart is described with considerable minuteness in the _Orygynale Cronykill_, by Andrew Wyntown, who was a canon of the priory. He says (Vol. I., p. 390):-- “Wilyhame Wyschard wes blessyd in Scone. Sevyn yhere and a half wes he Byschape, and gert byggyt be Nere all the body of the Kyrke: Quhare that he begowth to wyrk, Yhit men may the Taknys se Apper and be affinnetè, Ewyn owth[16] the thryd Pillare Frá the Chawnselare Dure[17] sene thare; Báth wndyre, and owth that south part, And the north syd swá westwart, And that west Gáivil alsuá In-til hys tyme all gert he má. And bot of hys Ethchettis[18] hále Hys Kyrk he endyd Cathedyrale, Bath in the Stane, and Thak, and Tre The body of hys Kyrk thus he In all thyng gert be byggyt welle, That langyt til it ilke dele.” [Illustration: FIG. 442.--St. Andrews Cathedral. Original East End.] Nothing is said about an earlier west end, but the description applies well to the later upper story of the south wall (see Fig. 448) and the lower story of the west end of the nave (see Fig. 450).
