=The South Transept= is narrower than the other by a yard, its width being 49 feet to the aisle wall (which, it should be noticed, has not been rebuilt). Without the aisle the width is only 30 feet, but this is partly due to the Perpendicular alterations. The end and west side of this transept, which remain more or less as they were in Archbishop Roger's day, resemble the corresponding walls of the other, yet with the following differences. The roof-shafts on the west side are thinner here than there, and are carried up to the required height in one piece, unbroken save by the string-courses. In connection with the attachment of shafts of any considerable height to wall-surfaces in Archbishop Roger's work, it will be observed that though the shafts (according to the general practice of masonry) are usually made in short joints built in at the back, yet (as here) their jointing sometimes does not harmonize with the coursing of the wall; again (as in the old nave and north transept) the shafts of a cluster are sometimes not worked all on the same stones. To return to the differences of this transept from the other, the roof-shafts over the inserted Perpendicular arch (which here obtrudes into the triforium) descend no lower than the sill of the clearstorey. Again, the thickening of the walls at the top is supported in the south-west angle not by one shaft but by two, one of which stands on a projecting strip of masonry that runs up the angle to the triforium. The design of the eighteenth century monument against the south wall, to Mr. Weddell of Newby, is taken from that of the choragic monument of Lysicrates at Athens.
