Canon Law, the typical study of the Middle Ages, is the _raison d’être_ of Trinity Hall. William Bateman, Bishop of Norwich, founded the College of the Scholars of the Holy Trinity of Norwich in 1350, in order to furnish his diocese with secular priests. His college occupied substantially the same ground as it does to-day. The founder, who also has a claim to be one of the founders of Caius, did not live long to enjoy his work. He was sent by Edward III. on an embassy to Innocent VI., in one of the numerous attempts at arbitration which varied the Hundred Years’ War. While engaged in these negotiations the Bishop died. His death was due to the climate of Avignon, which, in that season of plague, was more than ordinarily pestilent. “Avenio ventosa,” says the doggrel rhyme, “cum vento fastidiosa, sine vento venenosa.” Englishmen, with their usual mistrust of Papal honesty, said that Bateman had been poisoned. He left his foundations of Trinity Hall and the new Gonville Hall in a very incomplete state, and his executor, Archbishop Simon of Sudbury, although he did what he could in the way of building, was too much occupied with his fatal position in the state to attend closely to the condition of the colleges. In fact, Trinity Hall, composed of a master, twenty fellows and three scholars, was very badly off. Early in the fifteenth century they complained to Archbishop Arundel of the insufficiency of their commons, and obtained a dispensation by which they were empowered to add twopence for each weekday and a groat on the Lord’s day. Meanwhile, two of the masters of Trinity Hall are found among the list of bishops. These were the canonists Robert de Stretton, Bishop of Lichfield from 1360 to 1386, and Marmaduke Lumley, Bishop of Lincoln from 1450 to 1452. In the year 1525, Stephen Gardiner* became master. He was a native of Bury St Edmund’s and was a fellow of the college. In 1531, he was made Bishop of Winchester, but retained the mastership till his death, esteeming it a refuge to which, in those troublous times, he could always retire. He was, nevertheless, a little out of his reckoning. Although a reformer, he was of the conservative type and was not a _persona grata_ to Edward VI., who deprived him of both his mastership and bishoprick. His supplanter at Winchester was John Poynet; at Trinity Hall he was superseded by Walter Haddon, reputed to be the best Latinist of his time. Haddon was Professor of Law and Rhetoric and Public Orator, and, in addition to this, with the assistance of Sir John Cheke, compiled a new code of ecclesiastical law. His reforming activities gained him the Presidency of Magdalen College, Oxford, in 1552, from which he retired at Queen Mary’s accession. He died some years later and is buried in Christ Church, Newgate Street.
