particular union of Lutherans and Calvinists. Dury’s irenicism and philosemitism can be understood as interrelated aspects of an expansionist Protestant cause focussed on Britain, Ireland, continental Europe, and the Atlantic world. In this understanding, the Portuguese Jews (and American Indians) appear as victims of Spanish Catholicism in desperate need of Protestant help. Richard Popkin and Jefferey Jue have argued that Dury was a millenarian. His millenarian views are said to have pointed to 1655 as apocalyptic. Against that view it has been argued that Dury warned readers about attempts to predict the onset of the Millennium. In his preface to the millenarian tract Clavis Apocalyptica Dury seems to come out against the idea of a political millenarianism and to defend a more "moral" interpretation of millenarianism. Position in the Hartlib Circle Pansophism and alchemy Alchemy was within the interests of the Hartlibian group, and both Dury and his wife were involved. In 1649 they were quizzing Worsley on distillation. In the first half of 1651 Dury was a witness to George Starkey, in an apparent transmutation, and then recommended Starkey to Moriaen. Family In 1645 he married Dorothy Moore (née King), an Irish Puritan widow. Dorothy Durie (sic), daughter of Sir John King and Catherine Drury, was a noted writer on education and the role of women in the church. The match was arranged by Dorothy's niece, Katherine Jones, Viscountess Ranelagh (1615–1691), daughter of Richard Boyle, 1st Earl of Cork, and wife of Arthur Jones, 2nd Viscount Ranelagh. To be precise on the somewhat tenuous relationship, Arthur Moore, Dorothy's first husband, and Frances Jones née Moore, mother of Arthur Jones, were brother and sister, both children of Garret Moore, 1st Viscount Moore. By this marriage Dury was connected to Robert Boyle, brother of Lady Ranelagh. Their daughter Dora Katherina Dury (1654–77) was Henry Oldenburg's second wife. Dorothy also had two sons by her first husband.
