Whether this aisle was closed by some temporary arrangement at the east end, or whether an east wall was ever built, we cannot tell; no foundations of such a wall exist, so far as is known. Work, at any rate, seems to have stopped about 1310-20. It was not long before it was resumed, but the resumption was gradual. Three great works belong to the next stage—the building of the south chapel of the chancel and the crypt beneath, the rebuilding and northward extension of the north porch, and the building of the rood-screen. Both the south chapel and the extended porch were the result of the foundation of guilds and the multiplication of chantry services.[73] The south chapel itself, extending the whole length of the chancel, and connected with it by an arcade of four bays cut in its south wall, was probably the chapel of the chantry of St. Mary, founded by William Gunthorp. Richard Salteby, whose canopied tomb is in the south wall of the nave, immediately east of the south porch, founded the chantry of St. John the Baptist, whose services were probably performed at an altar near the southern staircase to the roof. This altar may have stood at first against the east wall of the aisle; later, it would have stood against the screen across the entrance of the Lady Chapel. Of the position of the other fourteenth-century chantries we know little; but one helpful document, enrolled among the public records, tells us of some of the altars and services in the church in 1349, and, in particular, of the altar in the rood-loft (_in solario coram magna cruce in medio ecclesie_), at which a chaplain said mass daily “after the first stroke of the bell which is called Daybelle”—the bell which still rings at five o’clock every morning from Lady Day to Michaelmas.[74] The crypt below the Lady Chapel, divided into an eastern and western portion, and approached by two doors on the outside of the church, may have contained other chantry chapels; but the western portion was possibly used as a bone-hole.
