teenth century as arising from Irish loyalty to the Catholic faith, when faced with the onslaughts of a heretical regime. Four of the nine chapters treat explicitly of the Catholic community. In other chapters, the insight that the vast majority of Irish Protestants were recent immigrants comes into view. How immigration from Scotland shaped what became the Presbyterian church in Ireland is considered, including the migration pattern of Scots within Ireland, and the recruitment and training of its clergy in Scotland. For Irish Anglicans, England as the source of clerical personnel and training played an analogous role, while the author allows for a serious engagement with Irish history and culture among some Church of Ireland figures. Mobility in the Protestant imagination is explored through Sir John Temple’s The Irish Rebellion (1646), the work of Andrew Stewart on the progress of Presbyterianism in Ireland, and John Vesey’s biography of that episcopal survivor, Archbishop John Bramhall. This work is bold in its conceptual approach, its attention to terminology informed by the social sciences, and its broad canvas which integrates consideration of the three confessions. It draws on a vast array of secondary literature which attempts to set Irish experience within a European context. In these ways it offers a fresh reading of Irish denominational history for the seventeenth century. However the lack of maps is regrettable, and there are a number of misprints. This book, large in size and in scope, considerably advances our understanding both of the experience of mobility, and of denominational identity formation, in seventeenth-century Ireland.
