Of the many clergy serving the Minster the Dean, who was the incumbent, ranked first. Much of the revenue of the Dean and Chapter, the Governing Body, came from landed possessions in York and various parts of the surrounding country. These possessions, divided into prebends, provided livings for the thirty-six prebendaries or canons, who collectively formed the Chapter. Each canon served at the Minster during a specified portion of the year, when he lived at his residence at York. The residences of the prebendaries were mostly round the Minster Close. While his own parish was served vicariously while he was at York, each canon had a minor-canon or vicar-choral to act as his deputy at York when he was absent. These vicars-choral formed a corporate body and lived collegiately in the Bedern. The numerous chantries in the Minster were served by priests who also lived collegiately but at St. William's College. The College, at the head of which was a Provost, was founded about the middle of the century. Previously these priests had lived in private houses. The parish priest was occupied in performing the services in his church, in hearing confessions, in teaching the children, in visiting, interrogating, consoling, and ministering the Sacraments to the sick and dying, and in guiding and sharing the life of his parish generally. Each parish church had a number of clergy besides the parish priest attached to it: the number varied from one to ten or more according to the number of chantries at the church. Each priest was helped a great deal in parochial affairs by the parish clerk. The latter was the chief lay official for business in connection with the parish church. His duties required him to be a man of some education. The Archbishop was both bishop of the diocese of York, and head of all the dioceses which together formed the Northern Province of the two provinces into which England was divided for the purpose of Church rule. His diocese formerly extended so far south as to include Nottingham and Southwell. The Archbishop was a Primate and occupied a high position in the State. Besides being supreme head of the Church in the northern province, he was a great landowner. He possessed, besides his palace near the Minster, a number of seats (like Cawood Castle) in the country. When he was in London he resided at his fine official palace, York House. The Archbishops were great lords of the realm in every way. Archbishop Neville, brother of Warwick "the king-maker," celebrated his installation in 1465 with a very famous feast. The huge amount and delicacy of the dishes prepared, the number of retainers employed, the splendour of the scene, which was honoured by the presence of the Duke of Gloucester and members of some of the most noble families in the kingdom, all the details of this sumptuous feast, were intended to impress King Edward IV. with the might of the Nevilles.
