“The design of the windows, thus reproduced from their original materials after being for four centuries immured, is very excellent and interesting. Internally they form a continuous arcade, supported on little clusters of light shafts, while externally--the lights being narrow, and the piers between them wide--the latter are occupied each by a double niche, a fellow to which flanks either jamb, so that while the arcade within consists of four arches, that without is formed of four _groups_ of arches, making twelve in all--four being windows and eight niches. The details of all are excellent; unfortunately, however, the roof of Bishop Vaughan’s Chapel prevents the external group from being seen with any effect, though within we have now, so far as the forms of the windows go, the ancient arrangement complete, and a most effective and beautiful one it is.” On the east wall of the tower the various weather-courses of previous roofs are visible, which make a not unnatural appeal to the imagination of the spectator. For the great defect of the exterior generally is that the roofs are of such a very flat pitch. =The Ruined Chapels=--on the south KING EDWARD’S, on the east that of OUR LADY, on the north of ST. NICHOLAS, and the Ante-Chapel--will be described later, as it is only by an unfortunate chance that they are now roofless (except the last), and will, we hope, shortly be correctly regarded as part of the interior if the proposed restoration takes place. Not far from the east end of the Lady Chapel is the spring which St. David is credited with creating. Giraldus[6] has a very pretty legend concerning this spring, which was known as St. Mary’s Well. It seems to have been of somewhat variable quality, as its waters were sometimes changed into milk and at others into wine. Sir G. Scott, however, with scant respect for its saintly origin, caused it to be drained! =The North Side= is much the more interesting of the two. After passing the chapels we come to a very curious three-storied building, the roof of which is higher than that of the cathedral. On the ground-floor was the Chantry of St. Thomas, now a vestry, entered from the east side of the north transept, and above this the turret stair from the north aisle of the presbytery leads to the old Chapter House, now the Library, and above this again is a disused room, once the Treasury. No parallel has yet been found for this remarkable building, which Freeman (1856) very accurately describes thus:[7]
