The entrance was from the west end, and the east end was occupied by two seats, one for the bishop and one for the prior. In the apse were five three-light windows of the Decorated period, and above the western door a five-light Perpendicular window, which contained coloured glass, illustrating the "Root of Jesse." On either side of this was a window of two lights, divided by a shaft and enclosed under one arch, carved with chevron ornament. There was also a round-headed Norman window in each of the north and south walls. A doorway in the south wall led to three chambers, one larger, and two smaller, which are stated in the "Rites of Durham" to have been used as a prison for the monks. The chapter-house was used in early times as a burial-place for the bishops, and many of their graves with inscriptions were in existence previous to the demolition of 1796. During excavations in 1874, the graves of Bishops Flambard, Galfrid Rufus, S. Barbara, de Insula, and Kellaw were opened, when various rings and the head of a crozier were discovered and removed to the dean and chapter library. The chapter-house has now been entirely restored as a memorial to the late Bishop Lightfoot. The #Northern Alley# of the Cloister, running along the south wall of the church, contains little of interest, except the two doorways previously described. The effect of the cloister as a whole, in its original condition, with the windows glazed, many containing fine stained glass, the oak roof with its heraldry and colour, and the lavatory in the centre of the garth, must have been exceptionally fine. [Illustration: The Exterior, from the South-east.] A sculptured panel on the north-west turret of the Nine Altar Chapel is now known as the #Dun Cow#. The original sculpture was replaced in the last century by the existing panel, but the legend connected with it is interesting. After their flight from Chester-le-Street, the monks, bearing the body of S. Cuthbert, remained some time at Ripon. While trying to return to Chester-le-Street, at a place called Wardlaw, the coffin stuck fast, and remained absolutely fixed. A fast of three days was proclaimed and kept, when it was revealed to them that they were to carry their saint to Dunholme. Still they were in difficulties, not knowing where Dunholme was, but fortune, or Providence, again favoured them. A woman, who had lost a cow, passed, calling to a companion to inquire if she had seen the animal. The reply was that her cow was in Dunholme; and, to the relief of the monks, they and their precious charge soon safely arrived there. In grateful commemoration of the incident Flambard erected this monument of a milkmaid and her cow. (See p. 9.)
