James III of Scotland, and in 1491 he baptised the future King Henry VIII of England. In 1492 he helped conclude the Peace of Etaples, and in 1493 he was chief commissioner in the negotiations for the famous commercial agreement with the Netherlands which Bacon seems to have been the first to call the Magnus Intercursus. Meanwhile, in July 1494 Foxe had been translated to the see of Durham, not merely because it was a richer see than Bath and Wells but because of its political importance as a palatine see and its location adjacent to the Borders and hence its importance for relations with Scotland. For these reasons rather than from any ecclesiastical scruples Foxe visited and resided in his new diocese; and he occupied Norham Castle, which he fortified and defended against a Scottish raid launched in 1497 in support of Perkin Warbeck. But his energies were principally devoted to pacific purposes. In that same year he negotiated Perkin's retirement from the court of James IV, and in 1498–1499 he completed the negotiations for that treaty of marriage between the Scottish king and Henry VII's daughter Margaret which led ultimately to the union of the two crowns in 1603 and of the two kingdoms in 1707. The marriage itself did not take place until 1503, just a century before the accession of James I. In August 1501 he was translated once more, this time to the see of Winchester, then reputed the richest diocese in England. In that year he brought to a conclusion marriage negotiations not less momentous in their ultimate results, when Prince Arthur was betrothed to Catherine of Aragon. His last diplomatic achievement in the reign of Henry VII was the betrothal of the king's younger daughter Mary to the future emperor Charles V. In 1500 Foxe was elected chancellor of Cambridge University and in 1507 master of Pembroke Hall, Cambridge. Lady Margaret Beaufort made him one of her executors, and in this capacity as well as in that of chancellor, he had the chief share with Fisher in regulating the foundation of St John's College, Cambridge, and the Lady Margaret professorships and readerships. His financial work brought him a less enviable notoriety, though history has deprived him of the credit which is his due for "Morton's Fork." The invention of that ingenious dilemma for extorting contributions from poor and rich alike is ascribed as
