On the south side of the Lady Chapel are two most interesting monuments of early bishops. That towards the east has been assigned to Bartholomew Iscanus (1161-84), but in all probability it represents one of his far earlier predecessors. The sculpture is almost archaic in style, the mitre low, the face bearded, and the type extraordinarily Byzantine. The left hand holds the pastoral staff, the point of which impales a winged dragon, with a sphinx-like head, at his feet. In the angles of the archway at the tomb are the figures of two angels with censers. The other tomb is that of Simon de Apulia (d. 1223). It presents a great contrast to that just described. The great advance made in the art of sculpture is noticeable in the more human character of the face, which is clean shaven, and the more skilful management of the hands. The artist, too, seems to have courted difficulties, for the bishop's robe and mitre are richly jewelled, and the foliage and animal at his feet, though conventional, are most elaborately designed. [Illustration: SCREEN OF ST. GABRIEL'S CHAPEL.] #Bishop Peter Quivil# (1291).--This tombstone in the centre of the pavement was restored here in 1820 on the representation of Mr. John Jones of Franklyn; the cross and letters were re-cut under his directions. The epitaph is "Petra tegit Petrum, nihil officiat sibi tetrum," and Westcott in his "View of Devon" writes, "which verse was written in an ancient character, each letter distant from the other at least four inches; so that this short verse supplied the whole large circumference, and cost me some labour in finding out and reading it." Certainly this is one of the most interesting memorials in the cathedral; indeed, it may be well considered the most interesting, for it is dedicated to the man by whose genius the whole great design was begotten. Its simplicity is noteworthy. But Quivil required no elaborate sepulture; the cathedral itself is his mighty monument, since it was he who founded-- "A fane more noble than the vestal trod-- The Christian's temple, to the Christian's God."[4] [4] Richard Clarke Sewell, 1825, Magdalen College.
