The library and the library keeper can play important roles in making knowledge available. As Dury points out, Oxford and Heidelberg have failed to do so. Dury's work enumerates very practical problems that need to be solved and integrates them into an overall picture of the library keeper, the library, the school, and the church--all fundamental components of a better world, if properly reformed. Reforming involves practical changes directed by the spiritual goal of preparing for the millennium. And it should be noticed that while Dury had time to worry about how much librarians should be paid and how books should be classified, and while he was occupied in getting the king's books in their proper place on the shelf, he was also convinced that the penultimate events before the onset of the millennium were about to take place. A month after his official appointment as deputy library keeper, Dury wrote the preface, dated 28 November 1650, to Abraham von Franckenberg's _Clavis Apocalyptica_. This work in Dury's translation of 1651 states on the title page that it offers a key to the prophecies in the books of Daniel and Revelation and "that the Prophetical Numbers com to an end with the year of our Lord 1655." The work, which Dury strongly endorses, lists as events "which are shortly to com to pass, collected out of the XI and XVI Chapters of the REVELATION," the destruction of the city of Rome, the end of the Turkish Empire, the conversion of the Jews, and the ruin of the whole papacy. Thereupon, the Devil will be cast out and shut up in the bottomless pit, and the Son of God will take "possession of the Kingdom" and reign for the millennium (pp. [164-65]). As is all too evident, Dury's reform projects did not lead to the millennium. He was active in England until sent abroad in 1654 as Cromwell's unofficial agent. Again he traveled all over Protestant Europe negotiating to reunite the churches. After the Restoration he was unable to return to England and lived out his life on the Continent trying to bring about Christian reunion. One of his last works, which has not been located, was a shady _Touchant l'intelligence de l'Apocalypse par l'Apocalypse meme_ of 1674. His daughter married Henry Oldenburg, who became a secretary of the Royal Society of England and who helped bring about some of the scientific reforms Dury had advocated. _Richard H.
