BESIDES the founder, whose misfortunes hindered the completion of his work, four successive kings aided in its erection. When Henry was taken prisoner at St. Albans in 1455, the Earls of Salisbury and Warwick promised to supply funds for the college buildings. For a time they kept their word, and some part of the £1,000 a year promised by Henry from the Duchy of Lancaster continued to be paid; but the defeat of the King at the battle of Towton in 1461 and the subsequent overthrow of the Lancaster dynasty checked progress. "After a long time spent in hiding in secret places, wherein for safety's sake he was forced to keep close, he was found and taken, brought as a traitor and criminal to London, and imprisoned in the Tower, and eventually suffered a violent death. He was buried at Chertsey Abbey, but his body was afterwards removed to Windsor Castle."[3] Still, the idea was there, and it remained for a later generation only to imitate and complete. In 1483, just before Edward IV's death, we find that nearly £1,300 had been spent on the chapel, about £1,100 given by the King, and £100 by Thomas Rotherham, Archbishop of York, Lord Chancellor of England, formerly a Fellow of the College, but it is not stated how the deficit was met. Richard III, on his accession, resumed the work with great vigour. Between May and December, 1484, about £750 was spent, nearly all of which was provided by the king. It is stated that in the year 1506 sufficient progress had been made in the building to admit of the performance of divine service, at which Henry VII and his mother, Margaret Countess of Richmond, Foundress of St. John's and Christ's Colleges, who were on a visit to Cambridge, were present; and it is said that John Fisher, President of Queens' College, Bishop of Rochester, took part as chief celebrant. Professor Willis, in _The Architectural History of the University of Cambridge_, takes exception to this statement. He is of opinion that, as the Screen and Stall work was not finished until 1536, and as the old Chapel[4] did not fall down until 1537 (in fact it was used on the eve of the day on which it fell), it is unlikely that the new chapel was used for service until that time. He further quotes Dr. Caius to strengthen this view.
