replaced by broad windows with flowing tracery. At the same period extensive work took place on the monastic buildings, including the construction of the elegant chapel of Prior Crauden. Chantry Chapels In the late fifteenth and early sixteenth centuries elaborate chantry chapels were inserted in the easternmost bays of the presbytery aisles, on the north for Bishop John Alcock (1486–1500) and on the south for Bishop Nicholas West (1515–33). John Alcock was born in around 1430, the son of a Hull merchant, but achieved high office in both church and state. Amongst his many duties and posts he was given charge of Edward IV's sons, who became known as the Princes in the Tower. That Alcock faithfully served Edward IV and his sons as well Henry VII adds to the mystery of how their fate was kept secret. Appointed bishop of Rochester and then Worcester by Edward IV, he was also declared 'Lord President of Wales' in 1476. On Henry VII's victory over Richard III in 1485, Alcock became interim Lord Chancellor and in 1486 was appointed Bishop of Ely. As early as 1476 he had endowed a chantry for his parents at Hull, but the resources Ely put at his disposal allowed him to found Jesus College, Cambridge and build his own fabulous chantry chapel in an ornate style. The statue niches with their architectural canopies are crammed so chaotically together that some of the statues never got finished as they were so far out of sight. Others, although completed, were overlooked by the destructions of the reformation, and survived when all the others were destroyed. The extent that the chapel is squashed in, despite cutting back parts of the Norman walls, raises the possibility that the design, and perhaps even some of the stonework, was done with a more spacious bay at Worcester in mind. On his death in 1500 he was buried within his chapel. Nicholas West had studied at Cambridge, Oxford and Bologna, had been a diplomat in the service of Henry VII and Henry VIII, and became Bishop of Ely in 1515. For the remaining 19 years of his life he 'lived in greater splendour than any other prelate of his time, having more than a hundred servants.' He was able to build the magnificent Chantry chapel at the south-east corner of the presbytery, panelled with niches for statues (which were destroyed or disfigured just
