Passing to the transepts we shall encounter the pleasant custom so rare in England (though common in France) of giving a familiar name to a great window. Here the splendid northern rose is called "The Dean's Eye," and its sister to the south "The Bishop's Eye," which names they have borne for more than six hundred years. Many are the reasons that have been advanced for these titles, but probably the practical one is correct, viz., the Dean's Eye faces the Deanery and the Bishop's Eye the Bishop's palace. Among the many fanciful and more poetic explanations there is one which, although it is less reasonable, we must be pardoned for finding more attractive, viz., as the north is the region of the Evil One, it is proper that the Dean's Eye should look into that direction in order to guard against any attempt on his part to invade the sanctuary. The Bishop's Eye is turned toward the sunny south, "The region of the Holy Spirit whose sweet influence alone can overcome the wiles of the wicked one." The older of the pair, the Dean's Eye, was probably glazed about 1220. It is best seen from the gallery or from the triforium which runs along just below it, and is a fine rose of the usual type. Below it there extends a row of five pointed lancets containing very light toned grisaille which almost entirely lacks the usual touches of colour. Below these are two larger lancets flanking the doorway; the one to the east has grisaille quarries as a border and within, geometric designs in colour. The westerly lancet shows a vine in whose branches are angels playing upon musical instruments, the whole surrounded by grisaille touched with colour. Across in the southern end of these transepts is one of the most delightful windows to be seen anywhere, the Bishop's Eye. Not only is this rose window a jewel of the glazier's art, but the mason as well has added a wondrous charm by the lightness of his stone traceries and the curious interpenetrated stone frame which he has placed about it. The architect, too, has joined in beautifying the _ensemble_ by stationing below it four large lancets of such harmonious proportions as admirably to balance and set off their more important neighbour just above them. In these lancets are found some Early English glass--broad borders of grisaille enframing the rich-toned medallions within. The Bishop's Eye was glazed about the middle of the fourteenth century and yields a warm greenish grey light. Instead of having its lines radiate from the centre in the customary manner, its gracefully curved mullions tend to flow up and down and suggest the fibres of five great leaves standing upright side by side.
