Meanwhile, Langton received much ecclesiastical preferment. In 1478 he was made treasurer of
Exeter,
prebendary of St. Decuman's,
Wells Cathedral, and about the same time master of
St. Julian's Hospital, Southampton, a post which he still retained twenty years later. He was presented on 1 July 1480 to
All Hallows Church, Bread Street, and on 14 May 1482 to
All Hallows, Lombard Street, City of London, also becoming prebendary of North Kelsey,
Lincoln Cathedral, in the next year. Probably by the favour of
King Edward V, who granted him the
temporalities of the see on 21 May, Langton was advanced in 1483 to the
bishopric of St. Davids; the
papal bull confirming the election is dated 4 July, and he was
consecrated in August or September. Langton's prosperity did not decline with Edward V's deposition. He was sent on an embassy to Rome and to France by
King Richard III, who
translated him to the
bishopric of Salisbury by papal bull dated 8 February 1485. Langton was also elected provost of
Queen's College, Oxford, on 6 December 1487, a post which he seems to have retained till 1495. He was a considerable
benefactor to the college, where he built some new sets of rooms and enlarged the provost's lodgings. In 1493
King Henry VII transferred him from Salisbury to
Winchester, a
see which had been vacant over a year. During the seven years that he was bishop of Winchester Langton started a school in the precincts of the palace, where he had youths trained in
grammar and music. He was a good musician himself, used to examine the scholars in person, and encourage them by good words and small rewards. Finally, a proof of his ever-increasing popularity, Langton was elected
Archbishop of Canterbury on 22 January 1501, but died of the
plague on the 27th, before the confirmation of the deed. He was buried in a marble tomb within 'a very fair chapel' which he had built south of the lady-chapel in
Winchester Cathedral. ==Death==
