=Archbishop John de Thoresby= (1352-1373) added to the prebend of Studley the two districts of Dacre and Bewerley, and it was probably about this time that the Lady-chapel (now the Library) was built. In 1375 some part of the church was burnt, and in 1396-7 the central spire seems to have been rebuilt. The town had now recovered its prosperity, for in 1405 it became the residence of the Court, when King Henry IV. was driven from Westminster by a plague. The next reign is marked by an improvement in the status of the Vicars. They had been living dispersed over the town,--indeed, their common residence or Bedern is said to have been destroyed by the Scots. In 1415, therefore, =Archbishop Henry Bowet= (1407-1423), having obtained from Henry V. a charter with a dispensation of the Statute of Mortmain, gave a site out of his manor for a new Bedern; and the vicars themselves, who at this period are commended by both the Archbishop and the King, were at the same time formed into a corporate body having a common seal, and were allowed to elect from their number a Provost. Under this Archbishop there were several instances of canons exchanging their stalls for other benefices. The discipline of the staff seems to have become exceedingly lax by 1439. The church music was neglected. The Mass of Our Lady was not said regularly in the Lady-chapel. The inferior clergy did not study for their examinations, and wore daggers in the Choir. They and the vicars frequented taverns, walked about the nave during service, and absented themselves without leave. The Canons did not attend church in their habits, and the clergy generally indulged in field sports. =Archbishop John Kemp= (1426-1452) did what he could to reform these abuses, and effected some improvement (the nature of which is not clear) in the status of the Vicars, who had been badly treated by the Chapter in financial matters. Later in this century a chantry chaplain is found engaging in dishonest trade; priests fight; laymen assault one another in the minster during service. But mediaeval morality in general must not be condemned, of course, for a few recorded crimes.
