The two large round windows in the end walls are the most interesting features of this transept. That on the north, the "=Dean's Eye=," is of the same date as its surroundings, and may be placed about the year 1220. The tracery of the southern window, the "=Bishop's Eye=," is much later; it is of the Decorated period, and was probably inserted soon after the middle of the fourteenth century. It has already been remarked that the row of quatrefoils above the window _outside_, are relics of the earlier tracery. Near this window was John de Dalderby's shrine. Although this bishop's admirers could not bring forward a record of sufficiently numerous miracles to procure his canonisation at the papal court, yet he was revered as a saint by the people, and it has been suggested that the offerings at his shrine may have supplied the means to insert the tracery of this window, as well as the one above, which lights the roof, and can only be seen from the outside. The round window has been sometimes called the "Prentice's Window"; but this name is never heard now, and the two "eyes" of the minster will always retain the name which they have borne for more than six hundred years. The "dean's eye" and the "bishop's eye" are both mentioned in the "Metrical Life of St. Hugh," which, it will be remembered, was written sometime between the years 1220 and 1235. The simplest explanation of the names seems to be that the one faces the deanery and the other faces the bishop's palace, but a far more poetic interpretation than this has been devised. The north is the region of Lucifer, and in that direction the dean's eye must look to guard against his approach. Meanwhile the bishop's eye is turned towards the sunny south, the region of the Holy Spirit, whose sweet influence alone can overcome the wiles of the wicked one. Both windows are filled with fine early glass. The "dean's eye" presents a most magnificent example of early thirteenth century stained glass, earlier than most of the glass at Canterbury, which is the richest of all our cathedrals in works of this nature. The subject has been described by C. Winston in the Lincoln volume (1848) of the Archæological Institute. It represents the Church on Earth and the Church in Heaven. In the centre is our Saviour seated in the midst of the Blessed in Heaven. Around are four large compartments, containing portions of different subjects, which do not appear to have all originally belonged to their present positions. The most interesting is that shewing the translation of the relics of St. Hugh, represented as borne on the shoulders of crowned and mitred personages. Of the sixteen outer circles, the topmost represents our Saviour seated on a rainbow; on either side are angels with the instruments of the Passion; in the next circles St. Peter and other saints are conducting holy persons to heaven; below these is the General Resurrection; the lowest five circles each contain the figure of an archbishop or bishop.
