Unfortunately the writer had only a very limited number of photographs of panels of the Great East Window to work upon, taken with a very primitive camera by his father over sixty years ago. If photographs of all the 108 subject panels were available, no doubt many more parallelisms with the St. William window could be identified.

^{page 276 note 2} In the Freemen's Roll for 1410 Thornton is described as ‘glacyer’. This is important, for there were other John Thorntons in York at that time, e.g. John Thornton, cordwainer, free 1405, and John Thornton, ‘motlemaker’, free 1407. Freemen of York, i, Surtees Soc, vol. xcvi.

^{page 277 note 2} The present writer has stated, more than once, that in his opinion the Fifteen Last Days of the Earth window in All Saints' church North Street is Thornton's work. It might possibly have been given to him to show what he could do with a set of subjects not dissimilar to those of the Creation which were required for the Great East Window. This would form a test of skill, and would be a natural preliminary precaution for the cathedral authorities to take. A later example occurred in connexion with the east window of Wadham College, Oxford, 1622. The artist, Bernard Van Linge, a young man in his twenties, appears to have been given a window at Kelvenden, Essex, to do as a test of skill, before being entrusted with the more important work. The date 1621 on the window, and the heraldry, were removed at the instance of a tractarian vicar, who regarded such things as pomps and vanities. (Communicated to the writer by the late Capt. Andrew Hamilton.)

^{page 278 note 2} In 1352–3 a John Coventre was one of the impressed glass-painters working on the windows of St. George's chapel, Windsor. (Vide Sir William St. John Hope's Windsor Castle.) He may have been identical with the John de Thornton who is mentioned in 1371, as holder of a tenement in the town of Coventry (Hist. MSS. Comm., Appen., part X, 1899, p. 140).

^{page 281 note 1} Illustrated in Knowles, J. A., York School of Glass Painting, fig. 15, p. 68.Google Scholar A curious and interesting thing is to be seen in this window. Some time during the fifteenth century, some accident must have happened to one of the figures of the kings (pl. XLII) (right-hand light, second panel up) which was evidently broken out through the mishandling of a scaffold pole or ladder, and the glass-painters have been called in to make good the damage. They have done this by making a tracing of King David, eliminating his harp, and changing the sceptre from the left to the right hand. But the head is very inferior to the original, the eyes are too close together, and the yellow stain muddy.

^{page 282 note 1} Were it not for the fact that the date of the St. Michael-le-Belfrey windows is established from dates in the inscriptions, it would be next to impossible to believe that many of them were executed some ten years later than the windows by Galyon Hone and partners, in King's College, Cambridge, the contract for which is dated 1526. They are executed in a debased Gothic style with only one or two insignificant Renaissance details.
