"In 1307 a general application was made to Clement V. for the purpose by the Dean and Chapter of Lincoln, who sent one of their number, Robert de Killingworth, to Rome with that object and also by the Dean and Chapter of St Paul's, London, the Abbot and convent of Osney, King Edward the First, Greenfield, Archbishop of York, and the University of Oxford. ...The most interesting testimony is that from the University of Oxford, which says that he never did anything connected with the office he held or his pastoral care through fear of any man, and that he was ready, if need be, to suffer martyrdom for what he believed to be right. It also speaks of his magnificent services to the cause of science, and of the admirable character of his "regency" at Oxford. What was the precise influence which prevented his canonisation is unknown, though his attitude of sturdy independence may have contributed to the result."
